The utilization of geothermal energy is nothing new. Within the last century, geothermal energy was harnessed by plants to produce energy.

Countries around the world, particularly those bordering and within the Ring of Fire, are weighing their options regarding geothermal energy. As it stands, geothermal energy has the global potential to generate 200 gigawatts of electricity, and the world is tapping into only 5 of it.

The United States and the Philippines lead the world in terms of geothermal development, although potential is underutilized. Nations in the Asia-Pacific region have the largest potential for growth in the geothermal sector, with some 74 GW waiting to be exploited through drilling and power plants. Japan has been slow to develop its potential, mainly due to issues with terrain, aesthetics and seismic activity however, its long dormancy is finally coming to an end.

South Korea is also preparing to boost its geothermal sector after thorough testing estimated that tapping 2 of the country's potential could provide as much energy as an entire year's demand. Australia, with more than 9 GW of regional geothermal potential at its disposal, is also pushing to increase its capacity. It currently does not rank among the top 10 nations capable of geothermal energy production.

Most geothermal development within Australia seems to be taking place after 2012, although a few projects may take off before then. Petratherm Limited plans to develop a small pilot plant near Arkaroola in South Australia starting at the end of next year. If the 3.75-megawatt MW Paralana project proves successful after completion in 2012, the company will immediately scale up the $45 million project to demonstration size before commercializing.

Initially, the new plant will supply power to a nearby uranium mine, though eventually it will be connected to local grid. Other projects are in the works as well, but Australia is in a state of flux as it determines the best routes of development through the utilization of enhanced geothermal systems, such as Paratherm's Paralana project.

Geothermal development became a hot topic in 2008 after the Australian Geothermal Energy Association's AGEA release of a report that suggested energy policies could allow for the development of more than 2 GW of geothermal power by 2020, which would cover up to 40 of the government's renewable energy targets. By then, renewable energy is projected to account for at least 20 of energy demand in Australia.

The AGEA also mentioned that developing only 1 of the region's geothermal potential could provide the country with enough energy to meet demands for more than 20,000 years. These estimates provide hopeful news as Australia depends mainly on coal for power needs and is one of the largest per capita carbon producers in the world.

National Grid and SSE to use electrical transformers to heat homes

Grid Transformer Waste Heat Recovery turns substations into neighborhood boilers, supplying district heating via heat networks, helping National Grid and SSE cut emissions, boost energy efficiency, and advance low carbon, net zero decarbonization.

 

Key Points

Grid Transformer Waste Heat Recovery captures substation heat for district heating, cutting emissions and gas use.

✅ Captures waste heat from National Grid transformers

✅ Feeds SSE district heat networks for nearby homes

✅ Cuts carbon, improves efficiency, aligns with net zero

 

Thousands of homes could soon be warmed by the heat from giant electricity grid transformers for the first time as part of new plans to harness “waste heat” and cut carbon emissions from home heating.

Trials are due to begin on how to capture the heat generated by transmission network transformers, owned by National Grid, to provide home heating for households connected to district heating networks operated by SSE.

Currently, hot air is vented from the giant substations to help cool the transformers that help to control the electricity running through National Grid’s high-voltage transmission lines.

However, if the trial succeeds, about 1,300 National Grid substations could soon act as neighbourhood “boilers”, piping water heated by the substations into nearby heating networks, and on into the thousands of homes that use SSE’s services.

“Electric power transformers generate huge amounts of heat as a byproduct when electricity flows through them. At the moment, this heat is just vented directly into the atmosphere and wasted,” said Nathan Sanders, the managing director of SSE Energy Solutions.

“This groundbreaking project aims to capture that waste heat and effectively turn transformers into community ‘boilers’ that serve local heat networks with a low- or even zero-carbon alternative to fossil-fuel-powered heat sources such as gas boilers, a shift akin to a gas-for-electricity swap in heating markets,” Sanders added.

Alexander Yanushkevich, National Grid’s innovation manager, said the scheme was “essential to achieve net zero” and a “great example of how, taking a whole-system approach, including power-to-gas in Europe precedents, the UK can lead the way in helping accelerate decarbonisation”.

The energy companies believe the scheme could initially reduce heat network carbon emissions by more than 40% compared with fossil gas systems. Once the UK’s electricity system is zero carbon, and with recent milestones where wind was the main source of UK electricity on the grid, the heating solution could play a big role in helping the UK meet its climate targets.

The first trials have begun at National Grid’s specially designed testing site at Deeside in Wales to establish how the waste heat could be used in district heating networks. Once complete, the intellectual property will be shared with smaller regional electricity network owners, which may choose to roll out schemes in their areas.

Tim O’Reilly, the head of strategy at National Grid, said: “We have 1,300 transmission transformers, but there’s no reason why you couldn’t apply this technology to smaller electricity network transformers, too, echoing moves to use more electricity for heat in colder regions.”

Once the trials are complete, National Grid and SSE will have a better idea of how many homes could be warmed using the heat generated by electricity network substations, O’Reilly said, and how the heat can be used in ways that complement virtual power plants for grid resilience.

“The heavier the [electricity] load, which typically reaches a peak at around teatime, the more heat energy the transformer will be able to produce, aligning with times when wind leads the power mix nationally. So it fits quite nicely to when people require heat in the evenings,” he added.

Other projects designed to capture waste heat to use in district heating schemes include trapping the heat generated on the Northern line of London’s tube network to warm homes in Islington, and harnessing the geothermal heat from disused mines for district heating networks in Durham.

Only between 2% and 3% of the UK is connected to a district heating network, but more networks are expected to emerge in the years ahead as the UK tries to reduce the carbon emissions from homes, alongside its nuclear power plans in the wider energy strategy.

Investigation underway to determine cause of Atlanta Airport blackout

Atlanta Airport Power Outage disrupts Hartsfield-Jackson as an underground fire cripples switchgear redundancy, canceling flights during holiday travel; Georgia Power restores electricity overnight while utility crews probe causes and monitor system resilience.

 

Key Points

A major Hartsfield-Jackson blackout from an underground fire; power restored as switchgear redundancy is investigated.

✅ Underground fire near Plane Train tunnel damaged switchgear systems

✅ Over 1,100 flights canceled; holiday travel severely disrupted

✅ Georgia Power restored service; redundancy and root cause under review

 

Power has been restored at the world’s busiest airport after a massive outage Sunday afternoon left planes and passengers stranded for hours, forced airlines to cancel more than 1,100 flights and created a logistical nightmare during the already-busy holiday travel season.

An underground fire caused a complete power outage Sunday afternoon at Hartsfield-Jackson Atlanta International Airport, resulting in thousands of canceled flights at the world's busiest terminal and affecting travelers worldwide.

The massive outage didn’t just leave passengers stranded overnight Sunday, it also affected travelers with flights Monday morning schedules.

According to Paul Bowers, the president and CEO of Georgia Power,  “From our standpoint, we apologize for the inconvenience,” he said. The utility restored power to the airport shortly before midnight.

Utility Crews are monitoring the fixes that restored power and investigating what caused the fire and why it was able to damage redundant systems. Bowers said the fire occurred in a tunnel that runs along the path of the underground Plane Train tunnel near Concourse E.

Sixteen highly trained utility personnel worked in the passageway to reconnect the network.“Our investigation is going through the process of what do we do to ensure we have the redundancy going back at the airport, because right now we are a single source feed,” Bowers said.

“We will have that complete by the end of the week, and then we will turn to what caused the failure of the switchgear.”

Though the cause isn’t yet known, he said foul play is not suspected.“There are two things that could happen,” he said.

“There are inner workings of the switchgear that could create the heat that caused the fire, or the splicing going into that switchgear -- that the cable had a failure on that going into the switch gear.”

When asked if age of the system could have been a failure, Bowers said his company conducts regular inspections.“We constantly inspect,” he said. “We inspect on an annual basis to ensure the reliability of the network, and that redundancy is protection for the airport.”Bowers said he is not familiar with any similar fire or outage at the airport.

“The issue for us is to ensure the reliability is here and that it doesn’t happen again and to ensure that our network is resilient enough to withstand any kind of fire,” he said. He added that Georgia Power will seek to determine what can be done in the future to avoid a similar event, such as those experienced during regional outages in other communities.

The German economy used to be the envy of the world. What happened?

Germany's Economic Downturn reflects an energy crisis, deindustrialization risks, export weakness, and manufacturing stress, amid Russia gas loss, IMF and EU recession forecasts, and debates over electricity price caps and green transition.

 

Key Points

An economic contraction from energy price shocks, export weakness, and bottlenecks in manufacturing and digitization.

✅ Energy shock after loss of cheap Russian gas

✅ Exports slump amid China slowdown and weak demand

✅ Policy gridlock on power price cap and permits

 

Germany went from envy of the world to the worst-performing major developed economy. What happened?

For most of this century, Germany racked up one economic success after another, dominating global markets for high-end products like luxury cars and industrial machinery, selling so much to the rest of the world that half the economy ran on exports.

Jobs were plentiful, the government’s financial coffers grew as other European countries drowned in debt, and books were written about what other countries could learn from Germany.

No longer. Now, Germany is the world’s worst-performing major developed economy, with both the International Monetary Fund and European Union expecting it to shrink this year.

It follows Russia’s invasion of Ukraine and the loss of Moscow’s cheap Russian gas that underpinned industry — an unprecedented shock to Germany’s energy-intensive industries, long the manufacturing powerhouse of Europe.

The sudden underperformance by Europe’s largest economy has set off a wave of criticism, handwringing and debate about the way forward.

Germany risks “deindustrialization” as high energy costs and government inaction on other chronic problems threaten to send new factories and high-paying jobs elsewhere, said Christian Kullmann, CEO of major German chemical company Evonik Industries AG.

From his 21st-floor office in the west German town of Essen, Kullmann points out the symbols of earlier success across the historic Ruhr Valley industrial region: smokestacks from metal plants, giant heaps of waste from now-shuttered coal mines, a massive BP oil refinery and Evonik’s sprawling chemical production facility.

These days, the former mining region, where coal dust once blackened hanging laundry, is a symbol of the energy transition, as the power sector’s balancing act continues with wind turbines and green space.

The loss of cheap Russian natural gas needed to power factories “painfully damaged the business model of the German economy,” Kullmann told The Associated Press. “We’re in a situation where we’re being strongly affected — damaged — by external factors.”

After Russia cut off most of its gas to the European Union, spurring an energy crisis in the 27-nation bloc that had sourced 40% of the fuel from Moscow, the German government asked Evonik to turn to coal by keeping its 1960s coal-fired power plant running a few months longer.

The company is shifting away from the plant — whose 40-story smokestack fuels production of plastics and other goods — to two gas-fired generators that can later run on hydrogen amid plans to become carbon neutral by 2030 and following the nuclear phase-out of recent years.

One hotly debated solution: a government-funded cap on industrial electricity prices to get the economy through the renewable energy transition, amid an energy crisis that even saw a temporary nuclear extension to stabilize supply.

The proposal from Vice Chancellor Robert Habeck of the Greens Party has faced resistance from Chancellor Olaf Scholz, a Social Democrat, and pro-business coalition partner the Free Democrats. Environmentalists say it would only prolong reliance on fossil fuels, while others advocate a nuclear option to meet climate goals.

Kullmann is for it: “It was mistaken political decisions that primarily developed and influenced these high energy costs. And it can’t now be that German industry, German workers should be stuck with the bill.”

The price of gas is roughly double what it was in 2021, with a senior official arguing nuclear would do little to solve that gas issue, hurting companies that need it to keep glass or metal red-hot and molten 24 hours a day to make glass, paper and metal coatings used in buildings and cars.

A second blow came as key trade partner China experiences a slowdown after several decades of strong economic growth.

These outside shocks have exposed cracks in Germany’s foundation that were ignored during years of success, including lagging use of digital technology in government and business and a lengthy process to get badly needed renewable energy projects approved.

UK Renewable Energy Auction: Boost for Wind and Tidal Power

UK Wind and Tidal Power Auction signals strong CfD support for offshore wind, tidal stream projects, investor certainty, and clean electricity, accelerating the net-zero transition, boosting jobs, and strengthening UK energy security and grid integration.

 

Key Points

A CfD auction awarding contracts for wind and tidal projects to scale clean power and advance UK net-zero.

✅ Offshore wind dominates CfD awards

✅ Tidal stream gains predictable, reliable capacity

✅ Jobs, investment, and grid integration accelerate

 

In a significant development for the UK’s renewable energy sector, the latest auction for renewable energy contracts has underscored a transformative shift towards wind and tidal power. As reported by The Guardian, the auction results reveal a strong commitment to expanding these technologies, with new contracts adding 10 GW to the UK grid, marking a pivotal moment in the UK’s transition to cleaner energy sources.

The Auction’s Impact

The renewable energy auction, which took place recently, has allocated contracts for a substantial increase in wind and tidal power projects. This auction, part of the UK’s Contracts for Difference (CfD) scheme, is designed to support the development of low-carbon energy technologies by providing financial certainty to investors. By offering fixed prices for the electricity generated by these projects, the CfD scheme aims to stimulate investment and accelerate the deployment of renewable energy sources.

The latest results are particularly notable for the significant share of contracts awarded to offshore wind farms and tidal power projects, highlighting how offshore wind is powering up the UK as policy and investment priorities continue to shift. This marks a shift from previous auctions, where solar power and onshore wind were the dominant technologies. The move towards supporting offshore wind and tidal power reflects the UK’s strategic focus on harnessing its abundant natural resources to drive the transition to a low-carbon energy system.

Offshore Wind Power: A Major Contributor

Offshore wind power has emerged as a major player in the UK’s renewable energy landscape, within a global market projected to become a $1 trillion business over the coming decades. The recent auction results highlight the continued growth and investment in this sector.

The UK has been a global leader in offshore wind development, with several large-scale projects already operational and more in the pipeline. The auction has further cemented this position, underscoring what the U.S. can learn from the U.K. in scaling offshore wind capacity, with new projects set to contribute significantly to the country’s renewable energy capacity. These projects are expected to deliver substantial amounts of clean electricity, supporting the UK’s goal of achieving net-zero emissions by 2050.

Tidal Power: An Emerging Frontier

Tidal power, although less developed compared to wind and solar, is gaining momentum as a promising renewable energy source, with companies harnessing oceans and rivers to demonstrate practical potential. The auction results have allocated contracts to several tidal power projects, signaling growing recognition of the potential of this technology.

Tidal power harnesses the energy from tidal movements and currents, which are highly predictable and consistent, and a market outlook for wave and tidal energy points to emerging growth drivers and investment. This makes it a reliable complement to intermittent sources like wind and solar power. The inclusion of tidal power projects in the auction reflects the UK’s commitment to diversifying its renewable energy portfolio and exploring all available options for achieving energy security and sustainability.

Economic and Environmental Benefits

The expansion of wind and tidal power projects through the recent auction offers numerous economic and environmental benefits. From an economic perspective, these projects are expected to create thousands of jobs in construction, maintenance, and manufacturing. They also stimulate investment in local economies and support the growth of the green technology sector.

Environmentally, the increased deployment of wind and tidal power contributes to significant reductions in greenhouse gas emissions. Offshore wind farms and tidal power projects produce clean electricity with minimal environmental impact, helping to mitigate the effects of climate change and improve air quality.

Challenges and Future Outlook

Despite the positive outcomes of the auction, there are challenges to address. Offshore wind farms and tidal power projects require substantial upfront investment and face technical and logistical challenges. Issues such as grid integration, environmental impact assessments, and supply chain constraints need to be carefully managed to ensure the successful deployment of these projects.

Looking ahead, the UK’s renewable energy strategy will continue to evolve as new technologies and innovations emerge, and growth despite Covid-19 underscores sector resilience. The success of the latest auction demonstrates the growing confidence in wind and tidal power and sets the stage for further advancements in renewable energy.

The UK government’s commitment to supporting these technologies through initiatives like the CfD scheme is crucial for achieving long-term energy and climate goals. As the country progresses towards its net-zero target, the continued expansion of wind and tidal power will play a key role in shaping a sustainable and resilient energy future.

Conclusion

The latest renewable energy auction represents a significant milestone in the UK’s transition to a low-carbon energy system. By awarding contracts to wind and tidal power projects, the auction underscores the country’s commitment to harnessing diverse and reliable sources of renewable energy. The expansion of offshore wind and the emerging role of tidal power highlight the UK’s strategic approach to achieving energy security, reducing emissions, and driving economic growth. As the renewable energy sector continues to evolve, the UK remains at the forefront of global efforts to build a sustainable and clean energy future.

Ireland goes 25 days without using coal to generate electricity

Ireland Coal-Free Electricity Record: EirGrid reports 25 days without coal on the all-island grid, as wind power, renewables, and natural gas dominated generation, cutting CO2 emissions, with Moneypoint sidelined by market competitiveness.

 

Key Points

It is a 25-day period when the grid used no coal, relying on gas and renewables to reduce CO2 emissions.

✅ 25 days coal-free between April 11 and May 7

✅ Gas 60%, renewables 30% of generation mix

✅ Eurostat: 6.8% drop in Ireland's CO2 emissions

 

The island of Ireland has gone a record length of time without using coal-fired electricity generation on its power system, Britain's week-long coal-free run providing a recent comparator, Eirgrid has confirmed.

The all-island grid operated without coal between April 11th and May 7th – a total of 25 days, it confirmed. This is the longest period of time the grid has operated without coal since the all-island electricity market was introduced in 2007, echoing Britain's record coal-free stretch seen recently.

Ireland’s largest generating station, Moneypoint in Co Clare, uses coal, with recent price spikes in Ireland fueling concerns about dispatchable capacity, as do some of the larger generation sites in Northern Ireland.

The analysis coincides with the European statistics agency, Eurostat publishing figures showing annual CO2 emissions in Ireland fell by 6.8 per cent last year; partly due to technical problems at Moneypoint.

Over the 25-day period, gas made up 60 per cent of the fuel mix, while renewable energy, mainly wind, accounted for 30 per cent, echoing UK wind surpassing coal in 2016 across the market. Coal-fired generation was available during this period but was not as competitive as other methods.

EirGrid group chief executive Mark Foley said this was “a really positive development” as coal was the most carbon intense of all electricity sources, with its share hitting record lows in the UK in recent years.

“We are acutely aware of the challenges facing the island in terms of meeting our greenhouse gas emission targets, mindful that low-carbon generation stalled in the UK in 2019, through the deployment of more renewable energy on the grid,” he added.

Last year 33 per cent of the island’s electricity came from renewable energy sources, German renewables surpassing coal and nuclear offering a parallel milestone, a new record. Coal accounted for 9 per cent of electricity generation, down from 12.9 per cent in 2017.

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. "If you're going to have a full and fair process, they have to be there."

[What you need to know about the CMP transmission line proposed for Maine]

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."
