Sunrise Technologies is teaming with Ember to turn the countryÂ’s grid of streetlights into a wide-area communications network for a host of new public utility, security, environmental and other applications.

Sunrise TechnologiesÂ’ new BrownBetty system creates a mesh network for communications between ground-based sensor and control devices and the Internet, utilizing EmberÂ’s ZigBee wireless network technology. By taking advantage of the existing streetlight infrastructure with its high elevation poles and clean line of sight, BrownBetty dramatically lowers the cost of backhaul communications while enabling applications that were previously not practical or affordable.

For utilities, these could include automatic meter reading (AMR), time-of-use metering (TOU), advanced metering infrastructure (AMI), remote water meter reading, remote electric meter disconnect, fault indication, distribution automation, and utility GPS mapping.

Other applications include Homeland Security sensor monitoring, peak period load shedding (air conditioners, water heaters, pool pumps, etc.), vehicle tracking, bridge stress monitoring, advanced parking meters (APM), storm drain blockage monitoring, water flow monitoring, home/business heating oil tank monitoring, and bridge stress monitoring, among many others.

The system gets its curious name from Brown Betty, the horse used by Paul Revere in his famous ride to alert the Minuteman in Lexington and Concord of the British ArmyÂ’s approach.

“BrownBetty makes smart use of ZigBee to eliminate the need for expensive long haul communications options like cellular, pagers or powerline,” said Bob Gohn, Ember’s Vice President of Marketing. “Because it uses standard based communications, BrownBetty can network work with any other ZigBee enabled devices to form a reliable and robust network.”

Inexpensive communication nodes are plugged into a streetlightÂ’s standard NEMA twist lock receptacles, replacing the lightÂ’s dusk to dawn photocontrols. Thanks to ZigBeeÂ’s self-forming network capabilities, the nodes automatically install themselves into the BrownBetty network, resulting in minimal installation costs. This local network communicates with a network computer operating center through bridge nodes which connect to the internet via fiber, broadband or WiFi connections. A single low cost node can communicate with multiple houses with multiple applications. Each node incorporates a photo control circuit to provide normal dusk to dawn lighting control of the streetlight.

Sunrise Technologies partnered with muNet, a provider of IP and ZigBee-based electric meter interfaces, in a successful pilot of the BrownBetty system at the Taunton Municipal Light Plant (TMLP) in Taunton, Mass. “The system is great because you can start inexpensively on a small scale and expand coverage and add on additional applications when you want them. It makes so many things more efficient,” said Mike Horrigan, General Manager for TMLP. Other participants in the project included NightHawk to perform remote electric meter disconnect/reconnect, DataMatic remote water meter reading, Graphic Technologies, Inc. (GTI) to provide geospatial data, and Power Delivery Products, Inc. for its faulted circuit indicators.

Vance Spillman, Vice President and General Manager of Sunrise Technologies said, “BrownBetty was created to fill the void of cost effective wide area coverage for backhaul of ZigBee device information to the Internet,” he said. “Smart grid implementation becomes instantly affordable. Adding the BrownBetty communications layer to Municipal WiFi systems makes the WiFi technology more useful. It adds value to the WiFi network and makes the WiFi network much more financially viable.”

The BrownBetty system used Ember’s EM250 ZigBee “system-on-chip” transceiver and EmberZNet PRO wireless mesh networking software. Sunrise Technologies realizes that Ember’s ZigBee technology addresses the need for a cost-effective, standards-based wireless networking solution that supports low data-rates, low-power consumption, security and reliability.

Ontario's electricity 'recovery rate' could lead to higher hydro bills

Ontario Hydro Flat Rate sets a single electricity rate at 12.8 cents per kWh, replacing time-of-use pricing for Ontario ratepayers, affecting hydro bills this summer, alongside COVID-19 Energy Assistance Program support.

 

Key Points

A fixed 12.8 cents per kWh electricity price replacing time-of-use rates across Ontario from June to November.

✅ Single rate applies 24/7, replacing time-of-use pricing

✅ May slightly raise bills versus pre-pandemic usage patterns

✅ COVID-19 aid offers one-time credits for households, small firms

 

A new provincial COVID-19 measure, including a fixed COVID-19 hydro rate designed to give Ontario ratepayers "stability" on their hydro bills this summer, could result in slightly higher hydro costs over the next four months.

Ontario Premier Doug Ford's government announced over the weekend that consumers would be charged a single around-the-clock electricity rate between June and November, before a Nov. 1 rate increase takes effect, replacing the much-derided time-of-use model ratepayers have complained about for years.

Instead of being charged between 10 to 20 cents per kilowatt hour, depending on the time of day electricity is used, including ultra-low TOU rates during off-peak hours, hydro users will be charged a blanket rate of 12.8 cents per kWh.

"The new rate will simply show up on your bill," Premier Doug Ford said at a Monday afternoon news conference.

While the government said the new fixed rate would give customers "greater flexibility" to use their home appliances without having to wait for the cheapest rate -- and has tabled legislation to lower rates as part of its broader plan -- the new policy also effectively erases a pandemic-related hydro discount for millions of consumers.

For example, a pre-pandemic bill of $59.90 with time-of-use rates, will now cost $60.28 with the government's new recovery rate, as fixed pricing ends across the province, before delivery charges, rebates and taxes.

That same bill would have been much cheaper -- $47.57 -- if the government continued applying the lowest tier of time-of-use 24/7 under an off-peak price freeze as it had been doing since March 24.

The government also introduced support for electric bills with two new assistance programs to help customers struggling to pay their bills.

The COVID-19 Energy Assistance Program will provide a one-time payment consumers to help pay off electricity debt incurred during the pandemic -- which will cost the government $9 million.

The government will spend another $8 million to provide similar assistance to small businesses hit hard by the pandemic.

Sub-Saharan Africa has a huge electricity problem - but with challenge comes opportunity

Sub-Saharan Africa Energy Access faces critical deficits; SDG7, clean energy finance, off-grid solar, and microgrids drive electrification for health, education, and economy amid World Bank and IEA efforts to expand reliable, affordable power.

 

Key Points

Reliable, affordable power in sub-Saharan Africa via renewables, off-grid solar, and SDG7-led electrification.

✅ SDG7 targets universal, modern energy access by 2030

✅ Off-grid solar and microgrids boost rural electrification

✅ Health, education, and business depend on reliable power

 

Sub-Saharan Africa has an electricity problem. While the world as a whole has made great strides when it comes to providing access to electricity and moving toward universal electricity access worldwide (the world average is now 90 per cent with access, up from 83 per cent in 2010), southern and western African states still lag far behind.

According to Tracking SDG7: The Energy Progress Report, produced by a consortium of organisations including the World Bank, the International Energy Agency and the World Health Organization, 759 million people were without electricity in 2019 and threequarters of them were based in sub-Saharan Africa. At just seven per cent, South Sudan had the lowest access figures; Chad, Burundi and Malawi were only marginally higher. What’s more, due to a combination of factors, the situation is getting worse. In total, the region’s access deficit increased from 556 million people in 2010 to 570 million people in 2019.

These days, being without electricity has an impact on every sphere of life. The Covid-19 pandemic only served to put this into sharper relief. Intermittent electricity meant vaccination doses that rely on cold storage were impossible to deliver and, as more than 70 per cent of the health facilities in sub-Saharan Africa have no access to reliable electricity, the problem was vast. But even without a global pandemic, having no power stymies opportunity in every field, from education to economics.

French photojournalist Pascal Maitre, who has spent much of his career writing about sub-Saharan Africa, wanted to document the problems faced by people in areas with no electricity. He thought particularly carefully about the location for his project. ‘First, I was thinking I could take images in the Democratic Republic of the Congo,’ he says. ‘But then I thought that if you chose a place that has war, it’s logical that electricity won’t really work. So, instead, I wanted to find a place that is quite stable. I decided to go to Benin, where they have a democracy. It is a good example of a country that’s not in really bad shape but where they still have this problem. Also, I didn’t want to go to a place that is very remote, where it is normal not to have good service. So I decided to go to a place around 50 kilometres from the capital that you can get to by road.’

Maitre visited several villages in the region, as well as making trips to Chad and Senegal, and encountered the full range of limitations engendered by the power shortage. From teachers struggling to conduct lessons in the dark to midwives forced to work with only the weak light from a phone, the situation was clearly unacceptable. ‘People were very, very, very upset,’ he says. ‘I conducted a lot of interviews in different villages and lack of electricity touches education, economy, business, security and also emigration, because people have to move to big cities or maybe to Europe to get jobs.’

Where once the situation might have been accepted as the norm, people today are fully aware of the ways in which they are held back by the lack of power. As Maitre remembers: ‘A guy said to me one day, “Do you think it is normal that last time my wife delivered a baby, the midwife had to hold her phone between her teeth in order to see what she was doing?” You feel very frustrated.’ He adds that the fact that most people now have mobile phones only highlights the hardship. ‘Before, maybe it was not so frustrating. But now, most of these people have cellphones. The cellphone company puts antennae everywhere so the phones work, but people cannot recharge their phones. They have to go to the market, where someone will come with a generator to recharge.’

Governments and global organisations are very aware of the problem across the world as a whole. Sustainable Development Goal 7 (SDG7) – one of the 17 goals set out in 2015 by the United Nations General Assembly – was designed to ensure universal access to affordable, reliable, sustainable and modern energy by 2030, underscoring the push for clean, affordable and sustainable electricity for all by 2030. As part of this goal, international financial flows to developing countries in support of clean energy reached US$17 billion in 2018. As a result, some areas have seen huge improvement. According to the Energy Progress Report, in Latin America and the Caribbean, and in Eastern and South-Eastern Asia, the advance of electrification has been enough to approach universal access. By 2019, in Western Asia and North Africa, and Central and South Asia, 94 and 95 per cent of the population respectively had access to electricity.

But these statistics only serve to emphasise just how bad the situation is in sub-Saharan Africa, where electricity systems are unlikely to go green this decade according to several analyses. As the report states: ‘While renewable energy has demonstrated remarkable resilience during the pandemic, the unfortunate fact is that gains in energy access throughout Africa are being reversed: the number of people lacking access to electricity is set to increase in 2020, making basic electricity services unaffordable for up to 30 million people who had previously enjoyed access.’

The small silver lining is that if the situation is dealt with properly, the region could build a renewable-energy system from the ground up, rather than having to undergo the costly and complex transitions underway in developed countries. In rural areas, small-scale or off-grid renewable systems (mostly solar) are expected to play an important role, as highlighted by a recent IRENA report on decarbonisation, in increasing access. In fact, solar panels are already used in many areas. In 2019, 105 million people had access to off-grid solar solutions, up from 85 million in 2016, and almost half lived in sub-Saharan Africa, with 17 million in Kenya and eight million in Ethiopia.

Rachel Kyte is currently serving as the 14th dean of the Fletcher School at Tufts University in the USA, but her CV is long. She was previously CEO of the UN-affiliated Sustainable Energy for All (SeforALL), as well as the World Bank Group vice president and special envoy for climate change, leading the run-up to the Paris Agreement. According to her, a focus on renewables is absolutely essential, both for wider efforts to tackle climate change, with some advocating a fossil fuel lockdown to drive a climate revolution, but also for the people of sub-Saharan Africa. ‘The fossil fuel industry has said it will just extend the centralised fossil-fuel power systems that we have today to reach these people,’ she says.

Demand for electricity in Yukon hits record high

Yukon Electricity Demand Record underscores peak load growth as winter cold snaps drive heating, lighting, and EV charging, blending hydro, LNG, and diesel with renewable energy and planned grid-scale battery storage in Whitehorse.

 

Key Points

It is the territory's new peak electricity load, reflecting winter demand, electric heating, EVs, and mixed generation.

✅ New peak: 104.42 MW, surpassing 2020 record of 103.84 MW

✅ Winter peaks met with hydro, LNG, diesel, and renewables mix

✅ Customers urged to shift use off peak hours and use timers

 

A new record for electricity demand has been set in Yukon. The territory recorded a peak of 104.42 megawatts, according to a news release from Yukon Energy.

The new record is about a half a megawatt higher than the previous record of 103.84 megawatts recorded on Jan. 14, 2020.

While in general, over 90 per cent of the electricity generated in Yukon comes from renewable resources each year, with initiatives such as new wind turbines expanding capacity, during periods of high electricity use each winter, Yukon Energy has to use its hydro, liquefied natural gas and diesel resources to generate the electricity, the release says.

But when it comes to setting records, Andrew Hall, CEO of Yukon Energy, says it's not that unusual.

"Typically, during the winter, when the weather is cold, demand for electricity in the Yukon reaches its maximum. And that's because folks use more electricity for heating their homes, for cooking meals, there's more lighting demand, because the days are shorter," he said.

"It usually happens either in December or sometimes in January, when we get a cold snap."

He said generally over the years, electricity demand has grown.

"We get new home construction, construction of new apartment buildings. And typically, those new homes are all heated by electricity, maybe not all of them but the majority," Hall said.

Efforts to curb climate change add to electricity demand
There are also other reasons, ones that are "in the name of climate change," Hall added.

That includes people trying to limit fossil fuel heating by swapping to electric heating. And, he said some Yukoners are switching to electric vehicles as incentives expand across the North.

"Over time, those two new demands, in the name of climate change, will also contribute to growing demand for electricity," he said.

While Yukon did reach this new all time high, Hall said the territory still hadn't hit the maximum capacity for the week, which was 118 megawatts, and discussions about a potential connection to the B.C. grid are part of long-term planning.

Tips to curve demand
"When we plan our system, we actually plan for a scenario, guided by the view that sustainability is key to the grid's future, where we actually lose our largest hydro generating facility," Hall said.

"We had plenty of generation available so it wasn't an emergency situation, and, even as other provinces face electricity shortages, it was more just an observation that hey, our peaks are growing."

He also said it was an opportunity to reach out to customers on ways to curve their demand for electricity around peak times, drawing on energy efficiency insights from other provinces, which is typically between 7 a.m. and 9 a.m., and between 5 p.m. and 7 p.m., Monday to Friday.

For example, he said, people should consider running major appliances, like dishwashers, during non-peak hours, such as in the afternoon rather than in the morning or evening.

During winter peaks, people can also use a block heater timer on vehicles and turn down the thermostat by one or two degrees.

'We plan for each winter'
Hall said Yukon Energy is working to increase its peak output, including working on a large grid scale battery to be installed in Whitehorse, similar to Ontario's energy storage push now underway. 

When it comes to any added load from people working from home due to COVID-19, Hall said they haven't noticed any identifiable increase there.

"Presumably, if someone's working from home, you know, their computer is at home, and they're not using the computer at the office," he said.

Yukon Energy one step closer to having largest battery storage site in the North
He said there shouldn't be any concern for maxing out the capacity of electricity demand as Yukon moves into the colder winter months, since those days are forecast for.

"This number of 104 megawatts wasn't unexpected," he said, adding how much electricity is needed depends on the weather too.

"We plan for each winter."

Avista Commissions Largest Solar Array in Washington

Adams Nielson Solar Array, a 28 MW DC utility-scale project in Lind, WA, spans 200 acres with 81,700 panels, powering about 4,000 homes, supporting Avista’s Solar Select program and renewable energy, sustainability, and carbon reduction.

 

Key Points

Adams Nielson Solar Array is a 28 MW DC facility in Lind, WA, powering ~4,000 homes via Avista’s Solar Select.

✅ 81,700 panels across 200 acres in Eastern Washington

✅ Offsets emissions equal to removing 7,300 cars annually

✅ Collaboration by Avista, Strata Solar, WUTC, WSU Energy

 

Official commissioning of the Adams Nielson solar array located in Lind, WA occurred today. The 28 Megawatt DC array is comprised of 81,700 panels that span 200 acres and generates enough electricity to supply the equivalent of approximately 4,000 homes annually, similar to a new co-op solar project serving South Metro members.

“Avista’s interest in the development of Solar Select, a voluntary commercial solar program reflecting broader corporate adoption such as a corporate solar power plant commissioned by Arvato, is consistent with the Company’s ongoing commitment to provide customers with renewable energy choices at reasonable cost,” said Dennis Vermillion, president, Avista Corporation. “In recent years, an increasing number of Avista customers have expressed their expectations and challenges in acquiring renewable energy. Avista is pleased to lead this effort and develop renewable energy products that meet our customers’ needs today and into the future.” This interest is being generated by a mix of local and national customers across a variety of industries, including Huckleberry’s, Gonzaga University, Community Colleges of Spokane, Hotstart, Central Pre-Mix Concrete, a CRH Co., independently owned McDonald's franchise locations, Spokane City, Main Market and Community Building and VA Medical Center.

Jim Simon, director of sustainability at Gonzaga University said, “The Solar Select program helps Gonzaga University move even closer to achieving its goal of climate neutrality by 2050 by continuing to prioritize renewables in our energy portfolio, as other communities add projects like a municipal solar project to boost local supply. We are grateful for Avista’s leadership in this project and look forward to other opportunities to reduce our greenhouse gas emissions.”

Spokane Mayor David Condon said, “The City of Spokane is pleased to partner with Avista through the Solar Select Program, as we continue to seek out opportunities that are both environmentally and financially responsible. The City already is a net producer of energy, generating more clean, green energy than our use of electricity, natural gas, and fuel, a milestone also seen with North Carolina's first wind farm now fully operational. We are excited to add even more clean energy to power City Hall.”

The Solar Select program created a cost-effective structure to bring solar energy to large business customers in Eastern Washington, allowing them to advance their desired sustainability goals and benefiting from industry service innovations led by companies like Omnidian expanding their global reach. The array is projected to deliver the environmental benefit equivalent of more than 7,300 cars removed from the road each year. This renewable energy program was made possible through a collaboration of Avista, Strata Solar, the Washington Utilities and Transportation Commission, and the WSU Energy Program.

Alberta creates fund to help communities hit by coal phase-out

Alberta Coal Community Transition Fund backs renewables, natural gas, and economic diversification, offering grants, workforce retraining, and community development to municipalities and First Nations as Alberta phases out coal-fired power by 2030.

 

Key Points

A provincial grant helping coal-impacted communities diversify, retrain workers, and transition to renewables by 2030.

✅ Grants for municipalities and First Nations

✅ Supports diversification and job retraining

✅ Focus on renewables, natural gas, and new sectors

 

The Coal Community Transition Fund is open to municipalities and First Nations affected as Alberta phases out coal-fired electricity by 2030 under the federal coal plan to focus on renewables and natural gas.

Economic Development Minister Deron Bilous says the government wants to ensure these communities thrive through the transition, aligning with views that fossil-fuel workers support the energy transition across the economy.

“Residents in our communities have concerns about the transition away from coal, even as discussions about phasing out fossil fuels in B.C. unfold nationally,” Rod Shaigec, mayor of Parkland County, said.

“They also have ideas on how we can mitigate the impacts on workers and diversify our economy, including clean energy partnerships to create new employment opportunities for affected workers. We are working to address those concerns and support their ideas. This funding means we can make those ideas a reality in various economic sectors of opportunity.”

The coal-mining town of Hanna, northeast of Calgary, has already received $450,000 through the program to work on economic diversification, exploring options like bridging the Alberta-B.C. electricity gap that could support new industries.

The application deadline for the coal transition fund is the end of November.

A provincial advisory panel is also expected to report back this fall on ways to create new jobs and retrain workers during the coal phase-out.

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."
