Cause of transformer fire unknown

Minnesota Electric Cooperatives are driving grid innovation with smart meters, time-of-use pricing, demand response, and energy storage, including iron-air batteries, to manage peak loads, integrate wind and solar, and cut costs for rural members.

Key Points

Member-owned utilities piloting load management, meters, and storage to integrate wind and solar, cutting peak demand.

✅ Time-of-use pricing pilots lower bills and shift peak load.

✅ Iron-air battery tests add multi-day, low-cost energy storage.

✅ Smart meters enable demand response across rural co-ops.

Minnesota electric cooperatives have quietly emerged as laboratories for clean grid innovation, outpacing investor-owned utilities on smart meter installations, time-based pricing pilots, and experimental battery storage solutions.

“Co-ops have innovation in their DNA,” said David Ranallo, a spokesperson for Great River Energy, a generation and distribution cooperative that supplies power to 28 member utilities — making it one of the state’s largest co-op players.

Minnesota farmers helped pioneer the electric co-op model more than a century ago, similar to modern community-generated green electricity initiatives, pooling resources to build power lines, transformers and other equipment to deliver power to rural parts of the state. Today, 44 member-owned electric co-ops serve about 1.7 million rural and suburban customers and supply almost a quarter of the state’s electricity.

Co-op utilities have by many measures lagged on clean energy. Many still rely on electricity from coal-fired power plants. They’ve used political clout with rural lawmakers to oppose new pollution regulations and climate legislation, and some have tried to levy steep fees on customers who install solar panels.

Where they are emerging as innovators is with new models and technology for managing electric grid loads — from load-shifting water heaters to a giant experimental battery made of iron. The programs are saving customers money by delaying the need for expensive new infrastructure, and also showing ways to unlock more value from cheap but variable wind and solar power.

Unlike investor-owned utilities, “we have no incentive to invest in new generation,” said Darrick Moe, executive director of the Minnesota Rural Electric Association. Curbing peak energy demand has a direct financial benefit for members.

Minnesota electric cooperatives have launched dozens of programs, such as the South Metro solar project, in recent years aimed at reducing energy use and peak loads, in particular. They include:

Cost calculations are the primary driver for electric cooperatives’ recent experimentation, and a lighter regulatory structure and evolving electricity market reforms have allowed them to act more quickly than for-profit utilities.

“Co-ops and [municipal utilities] can act a lot more nimbly compared to investor-owned utilities … which have to go through years of proceedings and discussions about cost-recovery,” said Gabe Chan, a University of Minnesota associate professor who has researched electric co-ops extensively. Often, approval from a local board is all that’s required to launch a venture.

Great River Energy’s programs, which are rebranded and sold through member co-ops, yielded more than 101 million kilowatt-hours of savings last year — enough to power 9,500 homes for a year.

Beyond lowering costs for participants and customers at large, the energy-saving and behavior-changing programs sometimes end up being cited as case studies by larger utilities considering similar offerings. Advocates supporting a proposal by the city of Minneapolis and CenterPoint Energy to allow residents to pay for energy efficiency improvements on their utility bills through distributed energy rebates used several examples from cooperatives.

Despite the pace of innovation on load management, electric cooperatives have been relatively slow to transition from coal-fired power. More than half of Great River Energy’s electricity came from coal last year, and Dairyland Power, another major power wholesaler for Minnesota co-ops, generated 70% of its energy from coal. Meanwhile, Xcel Energy, the state’s largest investor-owned utility, has already reduced coal to about 20% of its energy mix.

The transition to cleaner power for some co-ops has been slowed by long-term contracts with power suppliers that have locked them into dirty power. Others have also been stalled by management or boards that have been resistant to change. John Farrell, director of the Institute for Local Self-Reliance’s Energy Democracy program, said generalizing co-ops is difficult. 

“We’ve seen some co-ops that have got 75-year contracts for coal, that are invested in coal mines and using their newsletter to deny climate change,” he said. “Then you see a lot of them doing really amazing things like creating energy storage systems … and load balancing [programs], because they are unique and locally managed and can have that freedom to experiment without having to go through a regulatory process.”

Great River Energy, for its part, says it intends to reach 54% renewable generation by 2025, while some communities, like Frisco, Colorado, are targeting 100% clean electricity by specific dates. Its members recently voted to sell North Dakota’s largest coal plant, but the arrangement involves members continuing to buy power from the new owners for another decade.

The cooperative’s path to clean power could become clearer if its experimental iron-air battery project is successful. The project, the first of its kind in the country, is expected to be completed by 2023.

NB Power Pulp and Paper Subsidies lower electricity rates for six New Brunswick mills using firm power benchmarks and interruptible discounts, while government mandates, utility debt, ratepayer impacts, and competitiveness pressures shape provincial energy policy.

Key Points

Provincial mandates that buy down firm electricity rates for six mills to a national average, despite NB Power's debt.

✅ Mandated buy-down to match national firm electricity rates

✅ Ignores large non-firm interruptible power discounts

✅ Raises equity concerns amid NB Power debt and rate pressure

An effort to fix NB Power's struggling finances that is supposed to involve a look at "all options" will not include a review of the policy that requires the utility to subsidize electricity prices for six New Brunswick pulp and paper mills, according to the Department of Natural Resources and Energy Development.

The program is meant "to enable New Brunswick's pulp and paper companies have access to competitive priced electricity,"  said the department's communications officer Nick Brown in an email Monday 

"Keeping our large industries competitive with other Canadian jurisdictions, amid Nova Scotia rate hike opposition debates elsewhere, is important," he wrote, knocking down the idea the subsidy program might be scrutinized for shortcomings like other NB Power expenses.

Figures released last week show NB Power paid out $9.7 million in rate subsidies to the mills under the program in the fiscal year ended in March 2021, even though the utility was losing $4 million for the year and falling deeper into debt, amid separate concerns about old meter issues affecting households.

Subsidies went to three mills owned by J.D. Irving Ltd. including two in Saint John and one in Lake Utopia, two owned by the AV group in Nackawic and Atholville and the Twin Rivers pulp mill in Edmundston.

The New Brunswick government has made NB Power subsidize pulp and paper mills like Twin Rivers Paper Company since 2012, and is requiring the program to continue despite financial problems at the utility. (CBC)
It was NB Power's second year in a row of financial losses, while it is supposed to pay down $500 million of its $4.9 billion debt load in the next five years to prepare for the refurbishment of the Mactaquac dam, a burden comparable to customers in Newfoundland paying for Muskrat Falls elsewhere under separate policies, under a directive issued by the province

NB Power president Keith Cronkhite said he was "very disappointed" with debt increasing last year instead of  falling and senior vice president and chief financial officer Darren Murphy said everything would be under the microscope this year to turn the utility's finances around.  

"We need to do better," said Murphy on Thursday

"We need to step back and make sure we're considering all options, including approaches like Newfoundland's ratepayer shield agreement on megaproject overruns, to achieve that objective because the objective is quickly closing in on us."

However, reviewing the subsidy program for the six pulp and paper mills is apparently off limits.

The subsidy program requires NB Power to buy down the cost of "firm" electricity bought by pulp and paper mills to a national average that is calculated by the Department of Natural Resources and Energy Development.

Last year the province declared the price mills in New Brunswick pay to be an average of  7.536 cents per kilowatt hour (kwh).  It is higher than rates in five other provinces that have mills, which the province points to as justification for the subsidies, even as Nova Scotia's 14% rate hike approval highlights broader upward pressure, although the true significance of that difference is not entirely clear.

In British Columbia, the large forest products company Paper Excellence operates five pulp and paper mills which are charged 17.2 per cent less for firm electricity than the six mills in New Brunswick.

The Paper Excellence Paper Mill in Port Alberni, B.C. pays lower electricity prices than mills in New Brunswick, a benefit largely offset by higher property taxes. It's a factor New Brunswick does not count in calculating subsidies NB Power must pay. (Paper Excellence)
However, local property taxes on the five BC mills are a combined $7.8 million higher than the six New Brunswick plants, negating much of that difference.

The province's subsidy formula does not account for differences like that or for the fact New Brunswick mills buy a high percentage of their electricity at cheap non-firm prices.

Not counting the subsidies, NB Power already sells high volumes of what it calls interruptible and surplus power to industry at deep discounts on the understanding it can be cut off and redeployed elsewhere on short notice when needed.

Actual interruptions in service are rare.  Last year there were none, but NB Power sold 837 million kilowatt hours of the discounted power to industry at an average price of 4.9 cents per kwh.   

NB Power does not disclose how much of the $22 million or more in savings went to the six mills, but the price was 35 per cent below NB Power's posted rate for the plants and rivaled firm prices big mills receive anywhere in Canada, including Quebec.

Asked why the subsidy program ignores large amounts of discounted interruptible power used by New Brunswick mills in making comparisons between provinces, Brown said regulations governing the program require a comparison of firm prices only.

"The New Brunswick average rate is based on NB Power's published large industrial rate for firm energy, as required by the Electricity from Renewable Resources regulation," he wrote.

The subsidy program itself was imposed on NB Power by the province in 2012 to aid companies suffering after years of poor markets for forest products following the 2008 financial collapse and recession.  

Providing subsidies has cost NB Power $100 million so far and has continued even as markets for pulp products improved significantly and NB Power's own finances worsened.

Report warned against subsidies
NB Power has never directly criticized the program, but in a matter currently in front the of the New Brunswick Energy and Utilities Board looking at how NB Power might restructure its rates, including proposals such as seasonal rates that could prompt backlash, an independent consultant hired by the utility suggested rate subsidies to large export oriented manufacturing facilities, like pulp and paper mills, is generally a poor idea.

"We do not recommend offering subsidies to exporters," says the report by Christensen Associates Energy Consulting of Madison, Wis.

"There are two serious economic problems with subsidizing exports. The first is that the benefits may be less than the costs. The second problem is that subsidies tend to last forever, even if the circumstances that initially justified the subsidies have disappeared."

The Christensen report did not directly assess the merits of the current subsidy for pulp and paper mills but it addressed the issue because it said in the design of new rates "one NB Power business customer has raised the possibility that their electricity-intensive business ought to be granted subsidies because of the potential to generate extra benefits for the Province through increases in their exports"

That, said Christensen, rarely benefits the public.

"The direct costs of the subsidies are the subsidies themselves, a part of which ends up in the pockets of out-of-province consumers of the exported goods," said the report.  

"But there are also indirect costs due to the fact that the subsidies are financed through higher electricity prices, which means that other electricity customers have less money to spend on services provided by local businesses, thus putting a drag on the local economy."

The province does not agree.

Asked whether it has any studies or cost-benefit reviews that show the subsidy program is a net benefit to New Brunswick, the department cited none but maintained it is an important initiative, even as elsewhere governments have offered electricity bill credit relief to ratepayers.

"The program was designed to give large industrial businesses the ability to compete on a level energy field," wrote Brown.

Hydro-Quebec Crypto Mining Pause signals a temporary halt as blockchain power requests surge; energy regulator review will weigh electricity demand, winter peak constraints, tariffs, investments, and local jobs to optimize grid stability and revenues.

Key Points

A provincial halt on new miner power requests as Hydro-Quebec sets rules to safeguard demand, winter peaks, and rates.

✅ Temporary halt on new electricity sales to crypto miners

✅ Regulator to rank projects by jobs, investment, and revenue

✅ Winter peak demand and tariffs central to new framework

Major Canadian electricity provider Hydro-Québec will temporarily stop processing requests from cryptocurrency miners in order for the company to fulfil its obligations to supply energy to the entire province, while its global ambitions adjust to changing demand, according to a press release published June 7.

Hydro-Québec is experiencing “unprecedented” demand from blockchain companies, which reportedly exceeds the electric utility’s short and medium-term capacity. In this regard, the Quebec provincial government has ordered Hydro-Québec to halt electric power sales to cryptocurrency miners, and, following the New Hampshire rejection of Northern Pass announced a new framework for this category of electricity consumers.

In the coming days, Hydro-Québec will reportedly file an application to local energy regulator Régie de l'énergie, proposing a selection process for blockchain industry projects so as “not to miss the opportunities offered by this industry.” Regulators will reportedly target companies which can offer the province the most profitable economic advantages, including investments and local job creation.

#google#

Régie de l'énergie is instructed to consider “the need for a reserved block of energy for this category of consumers, the possibility of maximizing Hydro-Québec's revenues, and issues related to the winter peak period” as well as interprovincial arrangements like the Ontario-Québec electricity deal under discussion. Éric Filion, President of Hydro-Québec Distribution, said:

"The blockchain industry is a promising avenue for Hydro-Québec. Guidelines are nevertheless required to ensure that the development of this industry maximizes spinoffs for Québec without resulting in rate increases for our customers. We are actively participating in the Régie de l'énergie's process so that these guidelines can be produced as quickly as possible."

With this move, the government of Québec deviates from its decision to reportedly open the electricity market to miners at the end of last month, even as an Ontario-Quebec energy swap helps manage electricity demands. In March, the government said it was not interested in providing cheap electricity to Bitcoin miners, stating that cryptocurrency mining at a discount without any sort of “added value” for the local economy was unfavorable.

Hydro Quebec Power Consumption Record surges amid extreme cold, peak demand, and grid stress, as Hydro-Quebec urges energy conservation, load management, and reduced heating during morning and evening peaks across Montreal and southern Quebec.

Key Points

Quebec's grid hit 40,300 MW during an extreme cold snap, setting a new record and prompting conservation appeals.

✅ Lower thermostats 1-2 C in unused rooms during peak hours

✅ Delay dishwashers, dryers, and hot water use to off-peak

✅ Peak windows: 6-9 a.m. and 4-8 p.m.; import power if needed

Hydro Quebec says it has once again set a new record for power consumption, echoing record-breaking demand in B.C. in 2021 as extreme cold grips much of the province.

An extreme cold warning has been in effect across southern Quebec since Friday morning, straining the system, just as Calgary's electricity use soared during a frigid February, as Quebecers juggle staying warm and working from home.

Hydro Québec recorded consumption levels reaching 40,300 megawatts as of 8 a.m. Friday, breaking a previous record of 39,000 MW (with B.C. electricity demand hit an all-time high during a similar cold snap) that was broken during another cold snap on Jan 11. 

The publicly owned utility is now asking Quebecers to reduce their electricity consumption as much as possible today and tomorrow, a move consistent with clean electricity goals under federal climate pledges, predicting earlier in the morning the province would again reach an all-time high.

Reducing heating by just one or two degrees, especially in rooms that aren't being used, is one step that people can take to limit their consumption. They can also avoid using large appliances like the dishwasher and clothing dryer as often, and shortening the use of hot water. 

"They're small actions, but across millions of clients, it makes a difference," said Cendrix Bouchard, a spokesperson with Hydro Québec, while speaking with Tout un matin.

"We understand that asking this may pose challenges for some who are home throughout the day because they are working remotely, but if people are able to contribute, we appreciate it."

The best time to try and limit electricity usage is in the morning and evening, when electricity usage tends to peak, Bouchard said.

The province can import electricity from other regions if Quebec's system reaches its limits, even as the utility pursues selling to the United States as part of its long-term strategy, he added.

Temperatures dropped to –24 C in Montreal at 7 a.m., with a wind chill of –29 C. 

It will get colder across the south of the province through the evening and wind chills are expected to make it feel as cold as – 40 until Saturday morning, Environment Canada warned.

Those spending time outdoors are at a higher risk of frostbite and hypothermia.

"Frostbite can develop within minutes on exposed skin, especially with wind chill," Environment Canada said.

Conserving energy
Hydro-Québec has signed up 160,000 clients to a flexible billing plan similar to BC Hydro's winter payment plan that allows them to pay less for energy — as long as they use it during non-peak periods.

Quebec's energy regulator, the Régie de l'énergie, also forces crypto-currency mining operations to shut down for some hours  on peak-demand days, a topic where BC Hydro's approach to crypto mining has also drawn attention, Bouchard said.

Hydro-Québec says the highest consumption periods are usually between 6 a.m.-9 a.m. and 4 p.m.-8 p.m.

Duration Portfolio Energy Storage aligns layered peak demand with right-sized batteries, enabling peak shaving, gas peaker replacement, and solar-plus-storage synergy while improving grid flexibility, reliability, and T&D deferral through two- to four-hour battery durations.

Key Points

An approach that layers battery durations to match peaks, cut costs, replace peakers, and boost grid reliability.

✅ Layers 2- to 4-hour batteries by peak duration

✅ Enables solar-plus-storage and peak shaving

✅ Cuts T&D upgrades, emissions, and fuel costs

The debate over energy storage replacing gas-fired peakers has raged for years, but a new approach that shifts the terms of the argument could lead to an acceleration of storage deployments.

Rather than looking at peak demand as a single mountainous peak, some analysts now advocate a layered approach that allows energy storage to better match peak needs and complement ongoing efforts to improve solar and wind power across the grid.

"You don’t have to have batteries that run to infinity."

Some developers of solar-plus-storage projects, bolstered by cheap batteries, say they can already compete head-to-head with gas-fired peakers. "I can beat a gas peaker anywhere in the country today with a solar-plus-storage power plant," Tom Buttgenbach, president and CEO of developer 8minutenergy Renewables, recently told S&P Global.

Customers are very busy these days and rebate programs need to fit the speed of their life. Participation should be quick, easy, and accessible anywhere.

Others disagree. Storage is not disruptive for generation, but will be disruptive for transmission and distribution, Kris Zadlo, executive vice president and chief development officer at Invenergy, told the audience at a Bloomberg New Energy Finance conference last spring. Invenergy, like many renewable power developers, develops generation, energy storage and transmission projects.

But there is another path that avoids the pitfalls of positions on either end of the all-or-none approach. "Do the analysis of the need itself," Ray Hohenstein, market applications director at Fluence, told Utility Dive. If the need is only two hours in duration, it may be best served by a two-hour battery. "You don’t have to have batteries that run to infinity."

Storage vs. fossil fuel peakers

Energy storage has several benefits over traditional fossil fuel peaking plants, Hohenstein said. It is instantaneous, it has no emissions and requires no fuel, and has limited infrastructure needs. It can also help the grid absorb higher levels of renewable generation by soaking up excess output, such as solar power at noon, and many planned storage additions will be paired with solar in the next few years. But the one thing energy storage cannot do, he said, is provide limitless energy.

So, instead of looking at replacing an individual peaker, Hohenstein advocated a "duration portfolio" approach that uses energy storage to shave peak load.

If the need is for 150 MW of resources that will never need to run for more than two hours at a time, then a battery is "quite cheap," significantly less than a four or eight-hour battery, said Hohenstein. "If you fill up your peak by duration layer, it could be more cost effective."

NREL research driver

Fluence’s approach is informed by research by Paul Denholm and Robert Margolis at the National Renewable Energy Laboratory (NREL), released last spring.

The NREL researchers looked at the California market where they said 11 GW of fossil fuel capacity is expected to be retired by 2029 because of new once-through-cooling requirements that are taking effect. A lot of that capacity is peaking capacity and, according to NREL’s analysis, a large fraction could be replaced with four-hour energy storage, assuming continued storage cost reductions and growth in solar installations.

The key in NREL’s research was the level of solar power penetration. There is a "synergistic" relationship between solar penetration and storage deployment, the researchers wrote, and other studies suggest wind and solar could meet 80% of U.S. demand as these trends continue.

UK Nuclear Power Expansion is vital for low-carbon baseload, energy security, and Net Zero, complementing renewables like wind and solar, reducing gas reliance, and unlocking investment through clear financing rules and proven, dependable reactor technology.

Key Points

Accelerating reactor build-out for low-carbon baseload to boost energy security and help deliver the UK Net Zero target.

✅ Cuts gas dependence and stabilizes grids with firm capacity.

✅ Complements wind and solar for reliable, low-carbon supply.

✅ Needs clear financing to unlock investment and lower costs.

Leading nuclear industry figures will today call for a major programme of new power stations to hit ambitious emissions reduction targets.

The 19th Nuclear Industry Association annual conference in London will highlight the need for a proven, dependable source of low carbon electricity generation alongside growth in weather-dependent solar and wind power, and particularly the rapid expansion of wind and solar generation across the UK.

Without this, they argue, the country risks embedding a major reliance on carbon-emitting gas fired power stations as Europe loses nuclear capacity at a critical time for energy security for generations to come.

Annual public opinion polling released today to coincide with the conference revealed 75% of the population want the UK Government to take more action to reduce CO2 emissions.

The survey, conducted by YouGov in October 2019, has tracked opinion trends on nuclear for more than a decade. It shows continued and consistent public support for an energy mix including nuclear and renewables, with 72% of respondents agreeing this was needed to ensure a reliable supply of electricity.

Nuclear power was also perceived as the most secure energy source for keeping the lights on, compared to other sources such as oil, gas, coal, wind power, fracking and solar power.

Last month both the Labour and Conservative Parties committed to new nuclear power as part of their election Manifestos and the government's wider green industrial revolution plans for clean growth. At the same time, 27 leading figures in the fields of environment, energy, and industry signed an open letter addressed to parliamentary candidates, which set out the benefits of nuclear and underscored the consequences of not, at least, replacing the UK's current fleet of power stations.

The Nuclear Industry Association said there is no time to be lost in clarifying the ambition and the financing rules for new nuclear power which would bring down costs and unlock a major programme of investment.

Tom Greatrex, Chief Executive of the NIA, said "We have to grow the industry's contribution to a low carbon economy. The independent Committee on Climate Change said earlier this year that we need a variety of technologies including nuclear power/1 for net zero to reach the UK's Net Zero emissions target by 2050".

"This is a proven, dependable, technology with lower lifecycle CO2 emissions than solar power and the same as offshore wind/2. It is also an important economic engine for the UK, supporting uses beyond electricity and creating high quality direct and indirect employment for around 155,000 people."

"Right now nuclear provides 20%/3 of all the UK's electricity but all but one of our existing fleet will close over the next decade, amid the debate over nuclear's decline as power demand will only increase with a shift to electric heating and vehicles."

"The countries and regions which have most successfully decarbonised, like Sweden, France and Ontario in Canada, have done so by relying on nuclear, aligning with Canada's climate goals for affordable, safe power today. You are not serious about tackling climate change if you are not serious about nuclear".
