The U.S. military is growing increasingly concerned that proposed wind farms can disrupt or block radar designed to detect threats and protect America's skies, a problem that is stalling the alternative energy projects around the country.

A top U.S. general told Congress that federal agencies need to work better together on a formal vetting process for the wind projects to prevent them from being built where they will interfere with radar defenses.

Air Force Gen. Gene Renuart, head of U.S. Northern Command, said a number of projects raise "real concerns" involving radar interference, and he suggested that requiring companies to do early checks during the approval process for such obstruction may be needed.

"We've heard concerns that wind turbines may interfere with radar and impact military training routes," said House Armed Services Committee Chairman Ike Skelton, D-Mo. "While we must find new ways to meet our energy security needs, we must not compromise our national security."

While the radar interference issue is not new, it has become a bigger problem as more wind projects move through the permit process. Industry leaders and the Energy Department have said that wind power could provide as much as 20 percent of the nation's electricity by 2030.

Last month, Pentagon officials raised the issue with Congress, saying that they are devoting a lot of time and effort to the growing challenge of ensuring that energy projects don't conflict with military requirements.

"The current process for reviewing proposals and handling disputes is opaque, time-consuming and ad hoc," said Dorothy Robyn, deputy undersecretary of defense for installations and environment.

The Federal Aviation Administration reviews wind farm projects, looking at any interference with air navigation or radar systems. But while the FAA can flag problems during its review of a project, it cannot force a change or prevent a wind farm from being approved if a change is not made. Its recommendations, however, can sometimes affect a local zoning or other approval process.

Renuart and others say a more coordinated, interagency process is needed to better evaluate proposals.

It is difficult to say how many projects are tied up over the radar issue, but industry executives in a 2009 survey said that more than a dozen had been stalled, according to Laurie Jodziewicz, manager of siting policy for the American Wind Energy Association.

Jodziewicz said that projects totaling 10,000 megawatts of wind power were built in the U.S. last year, while projects involving another 10,000 megawatts were stalled by the radar issue. Projects vary in size and can include any number of turbines, but one turbine can generate between 1.5-3 megawatts of power in an hour at higher wind speeds.

The industry, Jodziewicz said, wants to work with federal agencies and officials are getting closer to finding a process that works. She conceded, however, that bringing everyone together can be a challenge.

Jodziewicz also said that at times the interference can be solved by upgrading the older radar systems, and that developers will work with the Defense Department to do those improvements.

In other cases the problem can be solved by shifting the configuration of the wind farm. Renuart said the North American Aerospace Defense Command, which he also heads, is putting together a radar obstruction evaluation team to determine the impacts of proposed wind energy projects in close proximity to our radars.

The Pentagon released a report in 2006 detailing the concerns with the wind farms, and said the Defense Department is developing other ways to deal with the problem, including technology improvements to the radar systems.

Opponent of Site C dam sharing concerns with northerners

Site C Dam Controversy highlights Peace River risks, BC Hydro claims, Indigenous rights under Treaty 8, environmental assessment findings, and potential impacts to agriculture and the Peace-Athabasca Delta across Alberta and the Northwest Territories.

 

Key Points

Debate over BC Hydro's Site C dam: clean energy vs Indigenous rights, Peace-Athabasca Delta impacts, and agriculture.

✅ Potential drying of Peace-Athabasca Delta and wildlife habitat

✅ Treaty 8 rights and First Nations legal challenges

✅ Loss of prime Peace Valley farmland; alternatives in renewables

 

One of the leading opponents of the Site C dam in northeastern B.C. is sharing her concerns with northerners this week.

Proponents of the Site C dam say it will be a cost-effective source of clean electricity, even as a major Alberta wind farm was scrapped elsewhere in Canada, and that it will be able to produce enough energy to power the equivalent of 450,000 homes per year in B.C. But a number of Indigenous groups and environmentalists are against the project.

Wendy Holm is an economist and agronomist who did an environmental assessment of the dam focusing on its potential impacts on agriculture.

On Tuesday she spoke at a town hall presentation in Fort Smith, N.W.T., organized by the Slave River Coalition. She is also speaking at an event in Yellowknife on Friday, as small modular reactors in Yukon receive study as a potential long-term option.

 

Worried about downstream impacts, Northern leaders urge action on Site C dam

"I learned that people outside of British Columbia are as concerned with this dam as we are," Holm said.

"There's just a lot of concern with what's happening on the Peace River and this dam and the implications for Alberta, where hydro's share has diminished in recent decades, and the Northwest Territories."

If completed, BC Hydro's Site C energy project will be the third dam on the Peace River in northeast B.C. and the largest public works project in B.C. history. The $10.7-billion project was approved by both the provincial and federal governments as B.C. moves to streamline clean energy permitting for future projects.

Amy Lusk, co-ordinator of the Slave River Coalition, said many issues were discussed at the town hall, but she also left with a sense of hope.

"I think sometimes in our little corner of the world, we are up against so much when it comes to industrial development and threats to our water," she said.

"To kind of take away that message of, this is not a done deal, and that we do have a few options in place to try and stop this and not to lose hope, I think was a very important message for the community."

 

Drying of the Peace-Athabasca Delta

Holm said her main concern for the Northwest Territories is how it could affect the Peace-Athabasca Delta. She said the two dams already on the river are responsible for two-thirds of the drying that's happening in the delta.

"These are very real issues and very present in the minds of northerners who want to stay connected to a traditional lifestyle, want to have access to those wild foods," she said.

Lusk said northerners are fed up with defending waters "time after time after time."

BC Hydro, however, said studies commissioned during the environmental assessment of Site C show the project will have no measurable effect on the delta, which is located 1,100 kilometres away.

Holm said the fight against the Site C dam is also important when it comes to First Nations treaty rights.

The West Moberly and Prophet River First Nations applied for an injunction to halt construction on Site C, as well as a treaty infringement lawsuit against the B.C. government. They argue the dam would cause irreparable harm to their territories and way of life, which are rights protected under Treaty 8.

 

Agricultural land

While the project is located in B.C., Holm said its impacts on prime horticulture land would also affect northerners, something that's important given issues of food security and nutrition.

"This is some of the best agriculture land in all of Canada," she said of the Peace Valley.

According to BC Hydro, around 2.6 million hectares of land in the Peace agricultural region would remain available for agricultural production while 3,800 hectares would be unavailable. It has also proposed a number of mitigation efforts, including a $20-million agricultural compensation fund.

Holm said renewable energy, including tidal energy for remote communities, will be cheaper and less destructive than the dam, and there's a connection between the dams on the Peace River and water sharing with the U.S.

"When you run out of water there's nothing else you can use. You can't use orange juice to irrigate your fields or to run your industries or to power your homes," she said.

No time to be silent on NZ's electricity future

New Zealand Renewable Energy Strategy examines decarbonisation, GHG emissions, and net energy as electrification accelerates, expanding hydro, geothermal, wind, and solar PV while weighing intermittency, storage, materials, and energy security for a resilient power system.

 

Key Points

A plan to expand electricity generation, balancing decarbonisation, net energy limits, and energy security.

✅ Distinguishes decarbonisation targets from renewable capacity growth

✅ Highlights net energy limits, intermittency, and storage needs

✅ Addresses materials, GHG build-out costs, and energy security

 

The Electricity Authority has released a document outlining a plan to achieve the Government’s goal of more than doubling the amount of electricity generated in New Zealand over the next few decades.

This goal is seen as a way of both reducing our greenhouse gas (GHG) emissions overall, as everything becomes electrified, and ensuring we have a 100 percent renewable energy system at our disposal. Often these two goals are seen as being the same – to decarbonise we must transition to more renewable energy to power our society.

But they are quite different goals and should be clearly differentiated. GHG emissions could be controlled very effectively by rationing the use of a fossil fuel lockdown approach, with declining rations being available over a few years. Such a direct method of controlling emissions would ensure we do our bit to remain within a safe carbon budget.

If we took this dramatic step we could stop fretting about how to reduce emissions (that would be guaranteed by the rationing), and instead focus on how to adapt our lives to the absence of fossil fuels.

Again, these may seem like the same task, but they are not. Decarbonising is generally thought of in terms of replacing fossil fuels with some other energy source, signalling that a green recovery must address more than just wind capacity. Adapting our lives to the absence of fossil fuels pushes us to ask more fundamental questions about how much energy we actually need, what we need energy for, and the impact of that energy on our environment.

MBIE data indicate that between 1990 and 2020, New Zealand almost doubled the total amount of energy it produced from renewable energy sources - hydro, geothermal and some solar PV and wind turbines.

Over this same time period our GHG emissions increased by about 25 percent. The increase in renewables didn’t result in less GHG emissions because we increased our total energy use by almost 50 percent, mostly by using fossil fuels. The largest fossil fuel increases were used in transport, agriculture, forestry and fisheries (approximately 60 percent increases for each).

These data clearly demonstrate that increasing renewable energy sources do not necessarily result in reduced GHG emissions.

The same MBIE data indicate that over this same time period, the amount of Losses and Own Use category for energy use more than doubled. As of 2020 almost 30 percent of all energy consumed in New Zealand fell into this category.

These data indicate that more renewable energy sources are historically associated with less energy actually being available to do work in society.

While the category Losses and Own Use is not a net energy analysis, the large increase in this category makes the call for a system-wide net energy analysis all the more urgent.

Net energy is the amount of energy available after the energy inputs to produce and deliver the energy is subtracted. There is considerable data available indicating that solar PV and wind turbines have a much lower net energy surplus than fossil fuels.

And there is further evidence that when the intermittency and storage requirements are engineered into a total renewable energy system, the net energy of the entire system declines sharply. Could the Losses and Other Uses increase over this 30-year period be an indication of things to come?

Despite the importance of net energy analysis in designing a national energy system which is intended to provide energy security and resilience, there is not a single mention of net energy surplus in the EA reference document.

So over the last 30 years, New Zealand has doubled its renewable energy capacity, and at the same time increased its GHG emissions and reduced the overall efficiency of the national energy system.

And we are now planning to more than double our renewable energy system yet again over the next 30 years, even as zero-emissions electricity by 2035 is being debated elsewhere. We need to ask if this is a good idea.

How can we expand New Zealand’s solar PV and wind turbines without using fossil fuels? We can’t.

How could we expand our solar PV and wind turbines without mining rare minerals and the hidden costs of clean energy they entail, further contributing to ecological destruction and often increasing social injustices? We can't.

Even if we could construct, deliver, install and maintain solar PV and wind turbines without generating more GHG emissions and destroying ecosystems and poor communities, this “renewable” infrastructure would have to be replaced in a few decades. But there are at least two major problems with this assumed scenario.

The rare earth minerals required for this replacement will already be exhausted by the initial build out. Recycling will only provide a limited amount of replacements.

The other challenge is that a mostly “renewable” energy system will likely have a considerably lower net energy surplus. So where, in 2060, will the energy come from to either mine or recycle the raw materials, and to rebuild, reinstall and maintain the next iteration of a renewable energy system?

There is currently no plan for this replacement. It is a serious misnomer to call these energy technologies “renewable”. They are not as they rely on considerable raw material inputs and fossil energy for their production and never ending replacement.

New Zealand is, of course, blessed with an unusually high level of hydro electric and geothermal power. New Zealand currently uses over 170 GJ of total energy per capita, 40 percent of which is “renewable”. This provides approximately 70 GJ of “renewable” energy per capita with our current population.

This is the average global per capita energy level from all sources across all nations, as calls for 100% renewable energy globally emphasize. Several nations operate with roughly this amount of total energy per capita that New Zealand can generate just from “renewables”.

It is worth reflecting on the 170 GJ of total energy use we currently consume. Different studies give very different results regarding what levels are necessary for a good life.

For a complex industrial society such as ours, 100 GJ pc is said to be necessary for a high levels of wellbeing, determined both subjectively (life satisfaction/ happiness measures), and objectively (e.g. infant mortality levels, female morbidity as an index of population health, access to nutritious food and educational and health resources, etc). These studies do not take into account the large amount of energy that is wasted either through inefficient technologies, or frivolous use, which effective decarbonization strategies seek to reduce.

Other studies that consider the minimal energy needed for wellbeing suggest a much lower level of per capita energy consumption is required. These studies take a different approach and focus on ensuring basic wellbeing is maintained, but not necessarily with all the trappings of a complex industrial society. Their results indicate a level of approximately 20 GJ per capita is adequate.

In either case, we in New Zealand are wasting a lot of energy, both in terms of the efficiency of our technologies (see the Losses and Own Use info above), and also in our uses which do not contribute to wellbeing (think of the private vehicle travel that could be done by active or public transport – if we had good infrastructure in place).

We in New Zealand need a national dialogue about our future. And energy availability is only one aspect. We need to discuss what our carrying capacity is, what level of consumption is sustainable for our population, and whether we wish to make adjustments in either our per capita consumption or our population. Both together determine whether we are on the sustainable side of carrying capacity. Currently we are on the unsustainable side, meaning our way of life cannot endure. Not a good look for being a good ancestor.

The current trajectory of the Government and Electricity Authority appears to be grossly unsustainable. At the very least they should be able to answer the questions posed here about the GHG emissions from implementing a totally renewable energy system, the net energy of such a system, and the related environmental and social consequences.

Public dialogue is critical to collectively working out our future. Allowing the current profit-driven trajectory to unfold is a recipe for disasters for our children and grandchildren.

Being silent on these issues amounts to complicity in allowing short-term financial interests and an addiction to convenience jeopardise a genuinely secure and resilient future. Let’s get some answers from the Government and Electricity Authority to critical questions about energy security.

Hydropower Plants to Support Solar and Wind Energy

Solar-Wind-Water West Africa integrates hydropower with solar and wind to boost grid flexibility, clean electricity, and decarbonization, leveraging the West African Power Pool and climate data modeling reported in Nature Sustainability.

 

Key Points

A strategy using hydropower to balance solar and wind, enabling reliable, low-carbon electricity across West Africa.

✅ Hydropower dispatch covers solar and wind shortfalls.

✅ Regional interconnection via West African Power Pool.

✅ Cuts CO2 versus gas while limiting new dam projects.

 

Hydropower plants can support solar and wind power, rather unpredictable by nature, in a climate-friendly manner. A new study in the scientific journal Nature Sustainability has now mapped the potential for such "solar-wind-water" strategies for West Africa: an important region where the power sector is still under development, amid IEA investment needs for universal access, and where generation capacity and power grids will be greatly expanded in the coming years. "Countries in West Africa therefore now have the opportunity to plan this expansion according to strategies that rely on modern, climate-friendly energy generation," says Sebastian Sterl, energy and climate scientist at Vrije Universiteit Brussel and KU Leuven and lead author of the study. "A completely different situation from Europe, where power supply has been dependent on polluting power plants for many decades - which many countries now want to rid themselves of."

Solar and wind power generation is increasing worldwide and becoming cheaper and cheaper. This helps to keep climate targets in sight, but also poses challenges. For instance, critics often argue that these energy sources are too unpredictable and variable to be part of a reliable electricity mix on a large scale, though combining multiple resources can enhance project performance.

"Indeed, our electricity systems will have to become much more flexible if we are to feed large amounts of solar and wind power into the grid. Flexibility is currently mostly provided by gas power plants. Unfortunately, these cause a lot of CO2 emissions," says Sebastian Sterl, energy and climate expert at Vrije Universiteit Brussel (VUB) and KU Leuven. "But in many countries, hydropower plants can be a fossil fuel-free alternative to support solar and wind energy. After all, hydropower plants can be dispatched at times when insufficient solar and wind power is available."

The research team, composed of experts from VUB, KU Leuven, the International Renewable Energy Agency (IRENA), and Climate Analytics, designed a new computer model for their study, running on detailed water, weather and climate data. They used this model to investigate how renewable power sources in West Africa could be exploited as effectively as possible for a reliable power supply, even without large-scale storage, in line with World Bank support for wind in developing countries. All this without losing sight of the environmental impact of large hydropower plants.

"This is far from trivial to calculate," says Prof. Wim Thiery, climate scientist at the VUB, who was also involved in the study. "Hydroelectric power stations in West Africa depend on the monsoon; in the dry season they run on their reserves. Both sun and wind, as well as power requirements, have their own typical hourly, daily and seasonal patterns. Solar, wind and hydropower all vary from year to year and may be impacted by climate change, including projections that wind resources shift southward in coming years. In addition, their potential is spatially very unevenly distributed."

West African Power Pool

The study demonstrates that it will be particularly important to create a "West African Power Pool", a regional interconnection of national power grids to serve as a path to universal electricity access across the region. Countries with a tropical climate, such as Ghana and the Ivory Coast, typically have a lot of potential for hydropower and quite high solar radiation, but hardly any wind. The drier and more desert-like countries, such as Senegal and Niger, hardly have any opportunities for hydropower, but receive more sunlight and more wind. The potential for reliable, clean power generation based on solar and wind power, supported by flexibly dispatched hydropower, increases by more than 30% when countries can share their potential regionally, the researchers discovered.

All measures taken together would allow roughly 60% of the current electricity demand in West Africa to be met with complementary renewable sources, despite concerns about slow greening of Africa's electricity, of which roughly half would be solar and wind power and the other half hydropower - without the need for large-scale battery or other storage plants. According to the study, within a few years, the cost of solar and wind power generation in West Africa is also expected to drop to such an extent that the proposed solar-wind-water strategies will provide cheaper electricity than gas-fired power plants, which currently still account for more than half of all electricity supply in West Africa.

Better ecological footprint

Hydropower plants can have a considerable negative impact on local ecology. In many developing countries, piles of controversial plans for new hydropower plants have been proposed. The study can help to make future investments in hydropower more sustainable. "By using existing and planned hydropower plants as optimally as possible to massively support solar and wind energy, one can at the same time make certain new dams superfluous," says Sterl. "This way two birds can be caught with one stone. Simultaneously, one avoids CO2 emissions from gas-fired power stations and the environmental impact of hydropower overexploitation."

Global relevance

The methods developed for the study are easily transferable to other regions, and the research has worldwide relevance, as shown by a US 80% study on high variable renewable shares. Sterl: "Nearly all regions with a lot of hydropower, or hydropower potential, could use it to compensate shortfalls in solar and wind power." Various European countries, with Norway at the front, have shown increased interest in recent years to deploy their hydropower to support solar and wind power in EU countries. Exporting Norwegian hydropower during times when other countries undergo solar and wind power shortfalls, the European energy transition can be advanced.

E.ON to Commission 2500 Digital Transformer Stations

E.ON Digital Transformer Stations modernize distribution grids with smart grid monitoring, voltage control, and remote switching, enabling bidirectional power flow, renewables integration, and rapid fault isolation from centralized grid control centres.

 

Key Points

Remotely monitored grid nodes enhancing smart grid stability and speedier fault response.

✅ Real-time voltage and current data along feeders and laterals

✅ Remote switching cuts outage duration and truck rolls

✅ Supports renewables and bidirectional power flows

 

E.ON plans to commission 2500 digital transformer stations in the service areas of its four German distribution grid operators - Avacon, Bayernwerk, E.DIS and Hansewerk - by the end of 2019. Starting this year, E.ON will solely install digital transformer stations in Germany, aligning with 2019 grid edge trends seen across the sector. This way, the digital grid is quite naturally being integrated into E.ON's distribution grids.

With these transformer stations as the centrepiece of the smart grid, it is possible to monitor and control using synchrophasors in the power grid from the grid control centre. This helps to maintain a more balanced utilisation of the grid and, with increasing complexity, ensures continued security of supply.

Until now, the current and voltage parameters required for safe grid operation could usually only be determined at the beginning of a power line, where there is usually a grid substation in place. Controlling current flow and voltage in the downstream system was physically impossible.

In the future, grids will have to function in both directions: they will bring electricity to the customer while at the same time collecting and transmitting more and more green electricity via HVDC technology where appropriate. This requires physical data to be made available along the entire route. To ensure security of supply, voltage fluctuations must be kept within narrowly defined limits and the current flow must not exceed the specified value, while reducing line losses with superconducting cables remains an important consideration. To manage this challenge, it is necessary to install digital technology.

The possibility of remotely controlling grids also reduces downtimes in the event of faults and supports a smarter electricity infrastructure approach. With the new technology, our grid operators can quickly and easily access the stations of the affected line. The grid control centres can thus limit and eliminate faults on individual line sections within a very short space of time.

Maryland’s renewable energy facilities break pollution rules, say groups calling for enforcement

Maryland Renewable Energy Violations highlight RPS compliance gaps as facilities selling renewable energy certificates, including waste-to-energy, biomass, and paper mills, face emissions and permit issues, prompting PSC and Attorney General scrutiny of environmental standards.

 

Key Points

Alleged RPS noncompliance by REC-eligible plants, prompting PSC review and potential decertification under Maryland law.

✅ Complaint targets waste-to-energy, biomass plants, and paper mills

✅ Facilities risk loss of REC certification for environmental violations

✅ PSC may investigate nonreporting; AG reviewing evidence

 

Many facilities that supply Maryland with renewable energy have exceeded pollution limits or otherwise broken environmental rules, violating a state law, according to a complaint sent by environmental groups to state energy and law enforcement officials.

Maryland law says that any company that contributes to a state renewable energy goal — half the state’s energy portfolio must come from renewable sources by 2030 — must “substantially comply” with rules on air and water quality and waste management. The complaint says more than two dozen power generators, including paper mills and trash incinerators, have records of formal or informal enforcement actions by environmental authorities.

For years, environmental groups have criticized Maryland policy that counts power plants that produce planet-warming carbon dioxide and health-threatening pollution as “renewable” energy generation, and similar tensions have emerged in California’s reliance on fossil fuels despite ambitious targets, but lawmakers concerned about protecting industrial jobs have resisted reforms. The renewable label qualifies the companies for subsidies drawn from energy bills across the state.

In a complaint filed this week, the groups asked the attorney general and Public Service Commission to step in.

“We’re subsidizing companies to produce dirty energy, but we’re also using ratepayer money to support companies that in many instances are paying environmental fines or just flouting the law,” said Timothy Whitehouse, executive director of Public Employees for Environmental Responsibility. “There’s no one to hold them to account in Maryland.”

A spokeswoman for Attorney General Brian Frosh said his office would review the complaint, which was signed by Whitehouse and Mike Ewall, executive director of the Energy Justice Network.

Public Service Commission officials said the facilities must notify them if found out of compliance with environmental rules, while at the federal level FERC action on aggregated DERs is shaping market participation, and the commission can then revoke certification under the state renewable energy program. In a statement, commission officials said they would launch an investigation if any facility had failed to notify them of any environmental violations, and encouraged anyone with evidence of such a transgression to file a complaint.

Companies named in the document accused the groups of painting an inaccurate picture.

“This complaint is based on misleading arguments designed to halt waste-to-energy practices that have clear environmental benefits recognized by the global scientific community,” said Jim Connolly, vice president of environment, health and safety for Wheelabrator, which owns a Baltimore trash incinerator.

Maryland launched its renewable energy program in 2004, diversifying the state’s energy portfolio with more environmentally friendly sources of power, even as regional debates over a Maine-Québec transmission line highlight cross-border impacts. Under the program, separate from the electricity they generate and sell to the grid, renewable power facilities can sell what are known as renewable energy certificates. Utilities such as Baltimore Gas and Electric Co. are required to buy a growing number of the certificates each year, essentially subsidizing the renewable energy facilities with money from ratepayer bills.

A dozen types of power generation qualify to sell the certificates: Solar, wind, geothermal and hydroelectric plants, as well as “biomass” facilities that burn wood and other organic matter, waste-to-energy plants that burn household trash and paper mills that burn a byproduct known as black liquor.

The complaint focuses on waste incinerators, biomass plants and paper mills, all of which environmental groups have cast as counter to the renewable energy program’s environmental goals, even as ACORE criticized a coal and nuclear subsidy proposal in federal proceedings.

“By subsidizing these corporations, Maryland is diverting the hard-earned income of Maryland ratepayers to wealthy corporations with poor environmental compliance records and undermining the state’s transition to clean renewable energy,” Whitehouse and Ewall wrote.

For example, they note that the Wheelabrator plant in Southwest Baltimore has been fined for exceeding mercury limits in the past. That occurred in 2011, when the plant settled with state regulators for violations in 2010 and 2009.

Connolly said there is “no question” the facility complies with Maryland’s renewable energy law.

Incinerators in Montgomery County and in Fairfax County, Virginia, that are owned by Covanta and sell the energy certificates in Maryland have been cited for accidental fires inside both facilities. The Maryland incinerator violated emissions rules in 2014, the same year that New Jersey forbade the Virginia facility from selling energy certificates into that state’s renewable energy program over concerns it wasn’t following ash testing regulations.

James Regan, a spokesman for Covanta, said both facilities “have excellent compliance records and they operate well below their permitted limits.” He said the Virginia facility is complying with ash testing requirements, and that both facilities emit far lower levels of pollutants such as particulate matter than vehicles do.

“It’s clear to us there’s a lot of misleading and wrong information in this document," Regan said.

The Environmental Protection Agency endorsed waste-to-energy facilities under former President Barack Obama because, while burning household trash emits carbon dioxide, scientists said that still had a smaller impact on global warming than sending trash to landfills, even as industry groups have backed the EPA in a legal challenge to the ACE rule as regulatory approaches shifted.

Environmentalists and community groups say the facilities still are harmful because they emit high levels of pollutants such as mercury, nitrogen oxides and lead. The concerns prompted Baltimore City Council to pass an ordinance in February that tightened emissions limits on the Wheelabrator facility, even as the new EPA pollution limits for coal and gas plants are being proposed, so dramatically that the company said it would no longer be able to operate once the rules go into effect in 2022.

The complaint does not mention the century-old Luke paper mill in Western Maryland that long faced criticism for its participation in the renewable energy program, but which owner Verso Co. closed this year.

It does say several of paper company WestRock’s mills in North Carolina and Virginia have faced both formal and informal EPA enforcement actions for violation of the Clean Water Act, including evolving EPA wastewater limits for power plants and other facilities, and the Clean Air Act. A WestRock spokesperson could not be reached for comment.

The complaint also says a large biomass facility in South Boston, Virginia, owned by the Northern Virginia Electric Cooperative has a record of noncompliance with the Clean Air Act over three years.

John Rainey, the plant’s operations director, said it “experienced some small exceedances to its permit limits,” but that it addressed the issues with Virginia environmental officials and has installed new technology.

All those plants have sold credits in Maryland.

Whitehouse said the environmental groups’ goal is to clean up Maryland’s renewable energy program. They did not file a lawsuit because he said there was no clear cause of action to take the state to court, but said he hopes the complaint nonetheless spurs action.

“It’s not acceptable in a clean energy program that we’re subsidizing some of the most dirty sources of energy,” he said. “Those sources aren’t even in compliance with the law, and no one seems to care.”

As Maine debates 145-mile electric line, energy giant with billions at stake is absent

Hydro-Quebec NECEC Transmission Line faces Maine PUC scrutiny over clean energy claims, greenhouse gas emissions, spillage capacity, resource shuffling, and Massachusetts contracts, amid opposition from natural gas generators and environmental groups debating public need.

 

Key Points

A $1B Maine corridor for Quebec hydropower to Massachusetts, debated over emissions, spillage, and public need.

✅ Maine PUC weighing public need and ratepayer benefits

✅ Emissions impact disputed: resource shuffling vs new supply

✅ Hydro-Quebec spillage claims questioned without data

 

As Maine regulators are deciding whether to approve construction of a $1 billion electricity corridor across much of western Maine, the Canadian hydroelectric utility poised to make billions of dollars from the project has been absent from the process.

This has left both opponents and supporters of the line arguing about how much available energy the utility has to send through a completed line, and whether that energy will help fulfill the mission of the project: fighting climate change.

And while the utility has avoided making its case before regulators, which requires submitting to cross-examination and discovery, it has engaged in a public relations campaign to try and win support from the region's newspapers.

Government-owned Hydro-Quebec controls dams and reservoirs generating hydroelectricity throughout its namesake province. It recently signed agreements to sell electricity across the proposed line, named the New England Clean Energy Connect, to Massachusetts as part of the state's effort to reduce its dependence on fossil fuels, including natural gas.

At the Maine Public Utilities Commission, attorneys for Central Maine Power Co., which would build and maintain the line, have been sparring with the opposition over the line's potential impact on Maine and its electricity consumers. Leading the opposition is a coalition of natural gas electricity generators that stand to lose business should the line be built, as well as the Natural Resources Council of Maine, an environmental group.

That unusual alliance of environmental and business groups wants Hydro-Quebec to answer questions about its hydroelectric system, which they argue can't deliver the amount of electricity promised to Massachusetts without diverting energy from other regions.

In that scenario, critics say the line would not produce the reduction in greenhouse gas emissions that CMP and Hydro-Quebec have made a central part of their pitch for the project. Instead, other markets currently buying energy from Hydro-Quebec, such as New York, Ontario and New Brunswick, would see hydroelectricity imports decrease and have to rely on other sources of energy, including coal or oil, to make up the difference. If that happened, the total amount of clean energy in the world would remain the same.

Opponents call this possibility "greenwashing." Massachusetts regulators have described these circumstances as "resource shuffling."

But CMP spokesperson John Carroll said that if hydropower was diverted from nearby markets to power Massachusetts, those markets would not turn to fossil fuels. Rather they would seek to develop other forms of renewable energy "leading to further reductions in greenhouse gas emissions in the region."

Hydro-Quebec said it has plenty of capacity to increase its electricity exports to Massachusetts without diverting energy from other places.

However, Hydro-Quebec is not required to participate -- and has not voluntarily participated -- in regulatory hearings where it would be subject to cross examinations and have to testify under oath. Some participants wish it would.

At a January hearing at the Maine Public Utilities Commission, hearing examiner Mitchell Tannenbaum had to warn experts giving testimony to "refrain from commentary regarding whether Hydro-Quebec is here or not" after they complained about its absence when trying to predict potential ramifications of the line.

"I would have hoped they would have been visible and available to answer legitimate questions in all of these states through which their power is going to be flowing," said Dot Kelly, a member of the executive committee at the Maine Chapter of the Sierra Club who has participated in the line's regulatory proceedings as an individual.

While Hydro-Quebec has not presented data on its system directly to Maine regulators, it has brought its case to the press. Central to that case is the fact that it's "spilling" water from its reservoirs because it is limited by how much electricity it can export. It said that it could send more water through its turbines and lower reservoir levels, eliminating spillage and creating more energy, if only it had a way to get that energy to market. Hydro-Quebec said the line would make that possible, and, in doing so, help lower emissions and fight climate change.

"We have that excess potential that we need to use. Essentially, it's a good problem to have so long as you can find an export market," Hydro-Quebec spokesperson Serge Abergel told the Bangor Daily News.

Hydro-Quebec made its "spillage" case to the editorial boards of The Boston Globe, The Portland Press Herald and the BDN, winning qualified endorsements from the Globe and Press Herald. (The BDN editorial board has not weighed in on the project).

Opponents have questioned why Hydro-Quebec is willing to present their case to the press but not regulators.

"We need a better answer than 'just trust us,'" Natural Resources Council of Maine attorney Sue Ely said. "What's clear is that CMP and HQ are engaging in a full-court publicity tour peddling false transparency in an attempt to sell their claims of greenhouse gas benefits."

Energy generators aren't typically parties to public utility commission proceedings involving the building of transmission lines, but Maine regulators don't typically evaluate projects that will help customers in another state buy energy generated in a foreign country.

"It's a unique case," said Maine Public Advocate and former Democratic Senate Minority Leader Barry Hobbins, who has neither endorsed nor opposed the project. Hobbins noted the project was not proposed to improve reliability for Maine electricity customers, which is typically the point of new transmission line proposals evaluated by the commission. Instead, the project "is a straight shot to Massachusetts," Hobbins said.

Maine Public Utilities Commission spokesperson Harry Lanphear agreed. "The Commission has never considered this type of project before," he said in an email.

In order to proceed with the project, CMP must convince the Maine Public Utilities Commission that the proposed line would fill a "public need" and benefit Mainers. Among other benefits, CMP said it will help lower electricity costs and create jobs in Maine. A decision is expected in the spring.

Given the uniqueness of the case, even the commission seems unsure about how to apply the vague "public need" standard. On Jan. 14, commission staff asked case participants to weigh in on how it should apply Maine law when evaluating the project, including whether the hydroelectricity that would travel over the line should be considered "renewable" and whether Maine's own carbon reduction goals are relevant to the case.

James Speyer, an energy consultant whose firm was hired by natural gas company and project opponent Calpine to analyze the market impacts of the line, said he has testified before roughly 20 state public utility commissions and has never seen a proceeding like this one.

"I've never been in a case where one of the major beneficiaries of the PUC decision is not in the case, never has filed a report, has never had to provide any data to support its assertions, and never has been subject to cross examination," Speyer said. "Hydro-Quebec is like a black box."

Hydro-Quebec would gladly appear before the Maine Public Utilities Commission, but it has not been invited, said spokesperson Abergel.

"The PUC is doing its own process," Abergel said. "If the PUC were to invite us, we'd gladly intervene. We're very willing to collaborate in that sense."

But that's not how the commission process works. Individuals and organizations can intervene in cases, but the commission does not invite them to the proceedings, commission spokesperson Lanphear said.

CMP spokesperson Carroll dismissed concerns over emissions, noting that Hydro-Quebec is near the end of completing a more than 15-year effort to develop its clean energy resources. "They will have capacity to satisfy the contract with Massachusetts in their reservoirs," Carroll said.

While Maine regulators are evaluating the transmission line, Massachusetts' Department of Public Utilities is deciding whether to approve 20-year contracts between Hydro-Quebec and that state's electric utilities. Those contracts, which Hydro-Quebec has estimated could be worth close to $8 billion, govern how the utility sells electricity over the line.

Dean Murphy, a consultant hired by the Massachusetts Attorney General's office to review the contracts, testified before Massachusetts regulators that the agreements do not require a reduction in global greenhouse gas emissions. Murphy also warned the contracts don't actually require Hydro-Quebec to increase the total amount of energy it sends to New England, as energy could be shuffled from established lines to the proposed CMP line to satisfy the contracts.

Parties in the Massachusetts proceeding are also trying to get more information from Hydro-Quebec. Energy giant NextEra is currently trying to convince Massachusetts regulators to issue a subpoena to force Hydro-Quebec to answer questions about how its exports might change with the construction of the transmission line. Hydro-Quebec and CMP have opposed the motion.

Hydro-Quebec has a reputation for guarding its privacy, according to Hobbins.

"It would have been easier to not have to play Sherlock Holmes and try to guess or try to calculate without having a direct 'yes' or 'no' response from the entity itself," Hobbins said.

Ultimately, the burden of proving that Maine needs the line falls on CMP, which is also responsible for making sure regulators have all the information they need to make a decision on the project, said former Maine Public Utilities Commission Chairman Kurt Adams.

"Central Maine Power should provide the PUC with all the info that it needs," Adams said. "If CMP can't, then one might argue that they haven't met their burden."

'They treat HQ with nothing but distrust'

If completed, the line would bring 9.45 terawatt hours of electricity from Quebec to Massachusetts annually, or about a sixth of the total amount of electricity Massachusetts currently uses every year (and roughly 80 percent of Maine's annual load). CMP's parent company Avangrid would make an estimated $60 million a year from the line, according to financial analysts.

As part of its legally mandated efforts to reduce carbon emissions and fight climate change, Massachusetts would pay the $950 million cost of constructing the line. The state currently relies on natural gas, a fossil fuel, for nearly 70 percent of its electricity, a figure that helps explain natural gas companies' opposition to the project.

A panel of experts recently warned that humanity has 12 years to keep global temperatures from rising above 1.5 degrees Celsius and prevent the worst effects of climate change, which include floods, droughts and extreme heat.

The line could lower New England's annual carbon emissions by as much as 3 million metric tons, an amount roughly equal to Washington D.C.'s annual emissions. Opponents worry that reduction could be mostly offset by increases in other markets.

But while both sides have claimed they are fighting for the environment, much of the debate features giant corporations with headquarters outside of New England fighting over the future of the region's electricity market, echoing customer backlash seen in other utility takeovers.

Hydro-Quebec is owned by the people of Quebec, and CMP is owned by Avangrid, which is in turn owned by Spanish energy giant Iberdrola. Leading the charge against the line are several energy companies in the Fortune 500, including Houston-based Calpine and Florida-based NextEra Energy.

However, only one side of the debate counts environmental groups as part of its coalition, and, curiously enough, that's the side with fossil fuel companies.

Some environmental groups, including the Natural Resources Council of Maine and Environment Maine, have come out against the line, while others, including the Acadia Center and the Conservation Law Foundation, are still deciding whether to support or oppose the project. So far, none have endorsed the line.

"It is discouraging that some of the environmental groups are so opposed, but it seems the best is the enemy of the good," said CMP's Carroll in an email. "They seem to have no sense of urgency; and they treat HQ with nothing but distrust."

Much of the environmentally minded opposition to the project focuses on the impact the line would have on local wildlife and tourism.

Sandi Howard administers the Say NO To NECEC Facebook page and lives in Caratunk, one of the communities along the proposed path of the line. She said opposition to the line might change if it was proven to reduce emissions.

"If it were going to truly reduce global CO2 emissions, I think it would be be a different conversation," Howard said.

 

Not the first choice

Before Maine, New Hampshire had its own debate over whether it should serve as a conduit between Quebec and Massachusetts. The proposed Northern Pass transmission line would have run the length of the state. It was Massachusetts' first choice to bring Quebec hydropower to its residents.

But New Hampshire's Site Evaluation Committee unanimously voted to reject the Northern Pass project in February 2018 on the grounds that the project's sponsor, Eversource, had failed to prove the project would not interfere with local business and tourism. Though it was the source of the electricity that would have traveled over the line, Hydro-Quebec was not a party to the proceedings.

In its decision, the committee noted the project would not reduce emissions if it was not coupled with a "new source of hydropower" and the power delivered across the line was "diverted from Ontario and New York." The committee added that it was unclear if the power would be new or diverted.

The next month, Massachusetts replaced Northern Pass by selecting CMP's proposed line. As the project came before Maine regulators, questions about Hydro-Quebec and emissions persisted. Two different analyses of CMP's proposed line, including one by the Maine Public Utility Commission's independent consultant, found the line would greatly reduce New England's emissions.

But neither of those studies took into account the line's impact on emissions outside of New England. A study by Calpine's consultant, Energyzt, found New England's emissions reduction could be mostly offset by increased emissions in other areas, including New Brunswick and New York, that would see hydroelectricity imports shrink as energy was redirected to fulfill the contract with Massachusetts.

'They failed in any way to back up those spillage claims'

Hydro-Quebec seemed content to let CMP fight for the project alone before regulators for much of 2018. But at the end of the year, the utility took a more proactive approach, meeting with editorial boards and providing a two-page letter detailing its "spillage" issues to CMP, which entered it into the record at the Maine Public Utilities Commission.

The letter provided figures on the amount of water the utility spilled that could have been converted into sellable energy, if only Hydro-Quebec had a way to get it to market. Instead, by "spilling" the water, the company essentially wasted it.

Instead of sending water through turbines or storing it in reservoirs, hydroelectric operators sometimes discharge water held behind dams down spillways. This can be done for environmental reasons. Other times it is done because the operator has so much water it cannot convert it into electricity or store it, which is usually a seasonal issue: Reservoirs often contain the most water in the spring as temperatures warm and ice melts.

Hydro-Quebec said that, in 2017, it spilled water that could have produced 4.5 terawatt hours of electricity, or slightly more than half the energy needed to fulfill the Massachusetts contracts. In 2018, the letter continued, Hydro-Quebec spilled water that could have been converted into 10.4 terawatts worth of energy. The company said it didn't spill at all due to transmission constraints prior to 2017.

 

The contracts Hydro-Quebec signed with the Massachusetts utilities are for 9.45 terawatt hours annually for 20 years. In its letter, the utility essentially showed it had only one year of data to show it could cover the terms of the contract with "spilled" energy.

"Reservoir levels have been increasing in the last 15 years. Having reached their maximum levels, spillage maneuvers became necessary in 2017 and 2018," said Hydro-Quebec spokesperson Lynn St. Laurent.

By providing the letter through CMP, Hydro-Quebec did not have to subject its spillage figures to cross examination.

Dr. Shaleen Jain, a civil and environmental engineering professor at the University of Maine, said that, while spilled water could be converted into power generation in some circumstances, spills happen for many different reasons. Knowing whether spillage can be translated into energy requires a great deal of analysis.

"Not all of it can be repurposed or used for hydropower," Jain said.

In December, one of the Maine Public Utility Commission's independent consultants, Gabrielle Roumy, told the commission that there's "no way" to "predict how much water would be spilled each and every year." Roumy, who previously worked for Hydro-Quebec, added that even after seeing the utility's spillage figures, he believed it would need to divert energy from other markets to fulfill its commitment to Massachusetts.

"I think at this point we're still comfortable with our assumptions that, you know, energy would generally be redirected from other markets to NECEC if it were built," Roumy said.

In January, Tanya Bodell, the founder and executive director of consultant Energyzt, testified before the commission on behalf of Calpine that it was impossible to know why Hydro-Quebec was spilling without more data.

"There's a lot of details you'd have to look at in order to properly assess what the reason for the spillage is," Bodell said. "And you have to go into an hourly level because the flows vary across the year, within the month, the week, the days. ...And, frankly, it would have been nice if Hydro-Quebec was here and brought their model and allowed us to see how this could help them to sell more."

Even though CMP and Hydro-Quebec's path to securing approval of the project does not go through the Legislature, and despite a Maine court ruling that energized Hydro-Quebec's export bid, lawmakers have taken notice of Hydro-Quebec's absence. Rep. Seth Berry, D-Bowdoinham, the House chairman of the Joint Committee On Energy Utilities and Technology and a frequent critic of CMP, said he would like to see Hydro-Quebec "show up and subject their proposal to examination and full analysis and public examination by the regulators and the people of Maine."

"They're trying to sell an incredibly lucrative proposal, and they failed in any way to back up those spillage claims with defensible numbers and defensible analysis," Berry said.

Berry was part of a bipartisan group of Maine lawmakers that wrote a letter to Massachusetts regulators last year expressing concerns about the project, which included doubts about whether the line would actually reduce global gas emissions. On Monday, he announced legislation that would direct the state to create an independent entity to buy out CMP from its foreign investors.

 

'No benefit to remaining quiet'

Hydro-Quebec would like to provide answers, but "there is always a commercially sensitive information concern when we do these things," said spokesperson Abergel.

"There might be stuff we can do, having an independent study that looks at all of this. I'm not worried about the conclusion," Abergel said. "I'm worried about how long it takes."

Instead of asking Hydro-Quebec questions directly, participants in both Maine and Massachusetts regulatory proceedings have had to direct questions for Hydro-Quebec to CMP. That arrangement may be part of Hydro-Quebec's strategy to control its information, said former Maine Public Utilities Commissioner David Littell.

"From a tactical point of view, it may be more beneficial for the evidence to be put through Avangrid and CMP, which actually doesn't have that back-up info, so can't provide it," Littell said.

Getting information about the line from CMP, and its parent company Avangrid, has at times been difficult, opponents say.

In August 2018, the commission's staff warned CMP in a legal filing that it was concerned "about what appears to be a lack of completeness and timeliness by CMP/Avangrid in responding to data requests in this proceeding."

The trouble in getting information from Hydro-Quebec and CMP only creates more questions for Hydro-Quebec, said Jeremy Payne, executive director of the Maine Renewable Energy Association, which opposes the line in favor of Maine-based renewables.

"There's a few questions that should have relatively simple answers. But not answering a couple of those questions creates more questions," Payne said. "Why didn't you intervene in the docket? Why are you not a party to the case? Why won't you respond to these concerns? Why wouldn't you open yourself up to discovery?"

"I don't understand why they won't put it to bed," Payne said. "If you've got the proof to back it up, then there's no benefit to remaining quiet."
