The State Grid Corporation of China (SGC) (Beijing) has decided to invest $340 million this year to improve the Hunan power grid's ability to withstand ice, according to Hunan Electric Power Company (Changsha), a subsidiary of SGC in Hunan Province.

From mid-January to mid-February of this year, the grid was greatly affected by the severe snowstorms that hit the country. The grid's transmission lines were encased in ice about 70 millimeters to 90 millimeters thick; the lines' designed limit was 15 millimeters to 20 millimeters.

The $340 million upgrade will cover six transmission lines with a total length of 531 kilometers and 38 crossovers at the 500-kilovolt (kV) level; 20 transmission lines with a total length of 733 kilometers and 38 crossovers at the 220 kV level; and 26 transmission lines with a total length of 452 kilometers and 165 crossovers at the 110 kV level.

Related departments of the SGC have been planning for various stages of the project, including tendering and construction. During construction, new technologies, new materials and new processes will be used. For instance, the application of multi-circuit, compact and narrow foundation steel pipe assembled towers will be adopted in 220 kV and 110 kV transmission lines.

Massive power line will send Canadian hydropower to New York

Twin States Clean Energy Link connects New England to Hydro-Quebec via a 1,200 MW transmission line, DOE-backed capacity, underground segments, existing corridors, boosting renewable energy reliability across Vermont and New Hampshire with cross-border grid flexibility.

 

Key Points

DOE-backed 1,200 MW line linking Hydro-Quebec to New England, adding clean capacity with underground routes.

✅ 1,200 MW cross-border capacity for the New England grid

✅ Uses existing corridors; underground in VT and northern NH

✅ DOE capacity contract lowers risk and spurs investment

 

A proposal to build a new transmission line to connect New England with Canadian hydropower is one step closer to reality.

The U.S. Department of Energy announced Monday that it has selected the Twin States Clean Energy Link as one of three transmission projects that will be part of its $1.3 billion cross-border transmission initiative to add capacity to the grid.

WBUR is a nonprofit news organization. Our coverage relies on your financial support. If you value articles like the one you're reading right now, give today.

Twin States is a proposal from National Grid, a utility company that serves Massachusetts, New York, and Rhode Island, and also owns transmission in England and Wales as the region advances projects like the Scotland-to-England subsea link that expand renewable flows, and the non-profit Citizens Energy Corporation.

The transmission line would connect New England with power from Hydro-Quebec, moving into the United States from Canada in Northern Vermont and crossing into New Hampshire near Dalton. It would run through parts of Grafton, Merrimack, and Hillsborough counties, routing through a substation in Dunbarton and ending at a proposed new substation in Londonderry. (Here's a map of the Twin States proposal.)

The federal funding will allow the U.S. Department of Energy to purchase capacity on the planned transmission line, which officials say reduces the risk for other investors and can help encourage others to purchase capacity.

The project has gotten support from local officials in Vermont and New Hampshire, but there are still hurdles to cross. The contract negotiation process is beginning, National Grid said, and the proposal still needs approvals from regulators before construction could begin.

First Nations communities in Canada have opposed transmission lines connecting Hydro-Quebec with New England in the past, and the company has faced scrutiny from environmental groups.

What would Twin States look like?
Transmission projects, like the failed Northern Pass proposal, have been controversial in New England, though the Great Northern Transmission Line progressed in Minnesota.

But Reihaneh Irani-Famili, vice president of capital delivery, project management and construction at National Grid, said this one is different because the developers listened to community concerns before planning the project.

“They did not want new corridors of infrastructure, so we made sure that we're using existing right of way,” she said. “They did not want the visual impact and some of the newer corridors of infrastructure, we're making sure we're undergrounding portions of the line.”

In Vermont and northern New Hampshire, the transmission lines would be buried underground along state roads. South of Littleton, they would be located within existing transmission corridors.

The developers say the lines could provide 1,200 megawatts of transmission capacity. The project would have the ability to carry electricity from hydro facilities in Quebec to New England, and would also be able to bring electricity from New England into Quebec, a step toward broader macrogrid connectivity across regions.

“Those hydro dams become giant green batteries for the region, and they hold that water until we need the electrons,” Irani-Famili said. “So if you think about our energy system not as one that sees borders, but one that sees resources, this is connecting the Quebec resources to the New England resources and helping all of us get into that cleaner energy future with a lot less build than we otherwise would have.”

Irani-Famili says the transmission line could help facilitate more clean energy resources like offshore wind coming online. In a report released last week by New Hampshire’s Department of Energy, authors said importing Canadian hydropower could be one of the most cost-effective ways to move away from fossil fuels on the electric grid.

National Grid estimates the project will help save energy customers $8.3 billion in its first 12 years. The developers are constructing a $260 million “community benefits plan” that would take some profits from the transmission line and give that money back to communities that host the transmission lines and environmental justice communities in New England.

New England takes key step to 1.2 GW of Quebec hydro as Maine approves transmission line

NECEC Clean Energy Connect advances with Maine DEP permits, Hydro-Québec contracts, and rigorous transmission line mitigation, including tapered vegetation, culvert upgrades, and forest conservation, delivering low-carbon power, broadband fiber, and projected ratepayer savings.

 

Key Points

A Maine transmission project delivering Hydro-Québec power with strict DEP mitigation, lower bills, and added broadband.

✅ DEP permits mandate tapered vegetation, culvert upgrades, land conservation

✅ Hydro-Québec to supply 9.55 TWh/yr via MA contracts; bill savings 2-4%

✅ Added broadband fiber in Somerset and Franklin; local tax benefits

 

The Maine DEP reviewed the Clean Energy Connect project for more than two years, while regional interest in cross-border transmission continued to grow, before issuing permits that included additional environmental mitigation elements.

"Collectively, the requirements of the permit require an unprecedented level of environmental protection and compensatory land conservation for the construction of a transmission line in the state of Maine," DEP said in a May 11 statement.

Requirements include limits on transmission corridor width, forest preservation, culvert replacement and vegetation management projects, while broader grid programs like vehicle-to-grid integration enhance clean energy utilization across the region.

"In our original proposal we worked hard to develop a project that provided robust mitigation measures to protect the environment," NECEC Transmission CEO Thorn Dickinson said in a statement. "And through this permitting process, we now have made an exceedingly good project even better for Maine."

NECEC will be built on land owned or controlled by Central Maine Power. The 53 miles of new corridor on working forest land will use a new clearing technique for tapered vegetation, while the remainder of the project follows existing power lines.

Environmentalists said they agreed with the decision, and the mitigation measures state regulators took, noting similar momentum behind new wind investments in other parts of Canada.

"Building new ways to deliver low-carbon energy to our region is a critical piece of tackling the climate crisis," CLF Senior Attorney Phelps Turner said in a statement. "DEP was absolutely right to impose significant environmental conditions on this project and ensure that it does not harm critical wildlife areas."

Once complete, Turner said the transmission line will allow the region "to retire dirty fossil fuel plants in the coming years, which is a win for our health and our climate."

The Massachusetts Department of Public Utilities in June 2019 advanced the project by approving contracts for the state's utilities to purchase 9,554,940 MWh annually from Hydro-Quebec. Officials said the project is expected to provide approximately 2% to 4% savings on monthly energy bills.

Total net benefits to Massachusetts ratepayers over the 20-year contract, including both direct and indirect benefits, are expected to be approximately $4 billion, according to the state's estimates.

NECEC "will also deliver significant economic benefits to Maine and the region, including lower electricity prices, increased local real estate taxes and reduced energy costs with examples like battery-backed community microgrids demonstrating local resilience, expanded fiber optic cable for broadband service in Somerset and Franklin counties and funding of economic development for Western Maine," project developers said in a statement.​

Washington County planning officials develop proposed recommendations for solar farms

Washington County solar farm incentives aim to steer projects to industrial sites with tax breaks, underground grid connections, decommissioning bonds, and wildlife corridors, balancing zoning, historic preservation, and Maryland renewable energy mandates.

 

Key Points

Policies steer solar to industrial sites with tax breaks, buried lines, and bonds, aligning with zoning and state goals.

✅ Tax breaks to favor rooftops and parking canopies

✅ Bury new grid lines to shift projects to industrial parks

✅ Require decommissioning bonds and wildlife corridors

 

Incentives for establishing solar farms at industrial spaces instead of on prime farmland are among the ideas the Washington County Planning Commission is recommending for the county to update its policies regarding solar farms.

Potential incentives would include tax breaks on solar equipment and requiring developers to put power-grid connections and line extensions underground, a move tied to grid upgrade cost debates in other regions, Planning Commission members said during a Monday meeting.

The tax break could make it more attractive for a developer to put a solar farm on a roof or over a parking lot, similar to California's building-solar requirement policies that favor rooftop generation, which could cost more than putting it on farmland, said Commission member Dave Kline, who works for FirstEnergy.

Requiring a company to bury new transmission lines could steer them to industrial or business parks where, theoretically, transmission lines are more readily available, Kline said Wednesday in a phone interview.

Chairman Clint Wiley suggested talking to industrial property owners to create a list of industrial sites that make sense for a solar site, which could generate extra income for the property owner.

Commission members also talked about requiring a wildlife corridor. Anne Arundel County requires such a corridor if a solar site is over 15 acres, according to Jill Baker, deputy director of planning and zoning. The solar site is broken into sections so animals such as deer can get through, she said.

However, that means the solar farm would take up more agricultural land, Commission member Jeremiah Weddle said. Weddle, a farmer, has repeatedly voiced concerns about solar farms using prime farmland.

County zoning law already states solar farms are prohibited in Rural Legacy Areas, Priority Preservation Areas, and within Antietam Overlay zones that preserve the Antietam National Battlefield viewshed. They also cannot be built on land with permanent preservation easements, Baker said.

However, a big reason county officials are looking to strengthen county policies for solar generating systems, or solar farms, is a recent court decision that ruled the Maryland Public Service Commission can preempt county zoning law when it comes to large solar farms.

County zoning law defines a solar energy generating system as a solar facility, with multiple solar arrays, tied into the power grid and whose primary purpose is to generate power to distribute and/or sell into the public utility grid rather than consuming that power on site.

The Maryland Court of Appeals ruled in July that the Public Service Commission can preempt local zoning regarding solar farms larger than 2 megawatts. But the ruling also stated local government is a "significant participant in the process" and the state commission must give "due consideration" to local zoning laws.

County officials are looking at recommendations for solar farms, whether they are over 2 megawatts or not.

Solar farms are a popular issue statewide, especially with Maryland solar subscriptions expanding, and were discussed at a recent Maryland Association of Counties meeting for planners, Planning and Zoning Director Stephen Goodrich said.

The thinking is the best way for counties to express their opinions about a solar project is to participate in the state commission's local public hearings, where issues like how solar owners are paid often arise, Goodrich said. Another popular idea is for the county to continue to follow its process, which requires a public hearing for a special exception to establish a solar farm. That will help the county form an opinion, on individual cases, to offer the state commission, he said.

Recommendations discussed by the Planning Commission include:

A break on personal property taxes, which is on equipment, including affordable battery storage that can firm output, to steer developers away from areas where the county doesn't want solar farms. The Board of County Commissioners have been split on tax-break agreements for solar farms, with a majority recently granting a few.

 

Protecting valuable historic sites.

Requiring a decommissioning bond for removing the equipment at the end of the solar farm's life. The bond is protection in case the company goes bankrupt. The county commissioners have been making such a bond a requirement when granting recent tax breaks.

Looking at allowing solar farms in stormwater-management areas.

Other counties, particularly in Western Maryland and on the Eastern Shore, are having issues with solar farms even as research to improve solar and wind advances, because land is cheaper and there are wide-open spaces, Goodrich said.

Many solar projects are being developed or proposed because state lawmakers passed legislation requiring 50% of electricity produced in the state to come from renewable sources by 2030, and a federal plan to expand solar is also shaping expectations. Of that 50%, 14.5% is to come from solar energy.

In Maryland, the average number of homes that can be powered by 1 megawatt of solar energy is about 110, according to the Solar Energy Industries Association's website.

Toronto Prepares for a Surge in Electricity Demand as City Continues to Grow

Toronto Electricity Demand Growth underscores IESO projections of rising peak load by 2050, driven by population growth, electrification, new housing density, and tech economy, requiring grid modernization, transmission upgrades, demand response, and local renewable energy.

 

Key Points

It refers to the projected near-doubling of Toronto's peak load by 2050, driven by electrification and urban growth.

✅ IESO projects peak demand nearly doubling by 2050

✅ Drivers: population, densification, EVs, heat pumps

✅ Solutions: efficiency, transmission, storage, demand response

 

Toronto faces a significant challenge in meeting the growing electricity needs of its expanding population and ambitious development plans. According to a new report from Ontario's Independent Electricity System Operator (IESO), Toronto's peak electricity demand is expected to nearly double by 2050. This highlights the need for proactive steps to secure adequate electricity supply amidst the city's ongoing economic and population growth.


Key Factors Driving Demand

Several factors are contributing to the projected increase in electricity demand:

Population Growth: Toronto is one of the fastest-growing cities in North America, and this trend is expected to continue. More residents mean more need for housing, businesses, and other electricity-consuming infrastructure.

  • New Homes and Density: The city's housing strategy calls for 285,000 new homes within the next decade, including significant densification in existing neighbourhoods. High-rise buildings in urban centers are generally more energy-intensive than low-rise residential developments.
  • Economic Development: Toronto's robust economy, a hub for tech and innovation, attracts new businesses, including energy-intensive AI data centers that fuel further demand for electricity.
  • Electrification: The push to reduce carbon emissions is driving the electrification of transportation and home heating, further increasing pressure on Toronto's electricity grid.


Planning for the Future

Ontario and the City of Toronto recognize the urgency to secure stable and reliable electricity supplies to support continued growth and prosperity without sacrificing affordability, drawing lessons from British Columbia's clean energy shift to inform local approaches. Officials are collaborating to develop a long-term plan that focuses on:

  • Energy Efficiency: Efforts aim to reduce wasteful electricity usage through upgrades to existing buildings, promoting energy-efficient appliances, and implementing smart grid technologies. These will play a crucial role in curbing overall demand.
  • New Infrastructure: Significant investments in building new electricity generation, transmission lines, and substations, as well as regional macrogrids to enhance reliability, will be necessary to meet the projected demands of Toronto's future.
  • Demand Management: Programs incentivizing energy conservation during peak hours will help to avoid strain on the grid and reduce the need to build expensive power plants only used at peak demand times.


Challenges Ahead

The path ahead isn't without its hurdles.  Building new power infrastructure in a dense urban environment like Toronto can be time-consuming, expensive, and sometimes disruptive, especially as grids face harsh weather risks that complicate construction and operations. Residents and businesses might worry about potential rate increases required to fund these necessary investments.


Opportunity for Innovation

The IESO and the city view the situation as an opportunity to embrace innovative solutions. Exploring renewable energy sources within and near the city, developing local energy storage systems, and promoting distributed energy generation such as rooftop solar, where power is created near the point of use, are all vital strategies for meeting needs in a sustainable way.

Toronto's electricity future depends heavily on proactive planning and investment in modernizing its power infrastructure.  The decisions made now will determine whether the city can support economic growth, address climate goals and a net-zero grid by 2050 ambition, and ensure that lights stay on for all Torontonians as the city continues to expand.

Hydro One will keep running its U.S. coal plant indefinitely, it tells American regulators

Hydro One-Avista Merger outlines a utility acquisition shaped by Washington regulators, Colstrip coal plant depreciation, and plans for renewables, clean energy, and emissions cuts, while Montana reviews implications for jobs, ratepayers, and a 2027 closure.

 

Key Points

A utility deal setting Colstrip depreciation and renewables, without committing to an early coal plant closure.

✅ Washington sets 2027 depreciation for Colstrip units

✅ Montana reviews jobs, ratepayer impacts, community fund

✅ Avista seeks renewables; no binding shutdown commitment

 

The Washington power company Hydro One is buying will be ready to close its huge coal-fired generating station ahead of schedule, thanks to conditions put on the corporate merger by state regulators there.

Not that we actually plan to do that, the company is telling other regulators in Montana, where coal unit retirements are under debate, the huge coal-fired generating station in question employs hundreds of people. We’ll be in the coal business for a good long time yet.

Hydro One, in which the Ontario government now owns a big minority stake, is still working on its purchase of Avista, a private power utility based in Spokane. The $6.7-billion deal, which Hydro One announced in July, includes a 15 per cent share in two of the four generating units in a coal plant in Colstrip, Montana, one of the biggest in the western United States. Avista gets most of its electricity from hydro dams and gas but uses the Colstrip plant when demand for power is high and water levels at its dams are low.

#google#

Colstrip’s a town of fewer than 2,500 people whose industries are the power plant and the open-pit mines that feed it about 10 million tonnes of coal a year. Two of Colstrip’s generators, older ones Avista doesn’t have any stake in, are closing in 2022. The other two will be all that keep the town in business.

In Washington, they don’t like the coal plant and its pollution. In Montana, the future of Colstrip is a much bigger concern. The companies have to satisfy regulators in both places that letting Hydro One buy Avista is in the public interest.

Ontario proudly closed the last of our coal plants in 2014 and outlawed new ones as environmental menaces, and Alberta's coal phase-out is now slated to finish by 2023. When Hydro One said it was buying Avista, which makes about $100 million in profit a year, Premier Kathleen Wynne said she hoped Ontario’s “value system” would spread to Avista’s operations.

The settlement is “an important step towards bringing together two historic companies,” Hydro One’s chief executive Mayo Schmidt said in announcing it.

The deal has approval from the Washington Utilities and Transportation Commission staff but is subject to a vote by the group’s three commissioners. It doesn’t commit Avista to closing anything at Colstrip or selling its share. But Avista and Hydro One will budget as if the Colstrip coal burners will close in 2027, instead of running into the 2040s as their owners had once planned, a timeline that echoes debates over the San Juan Generating Station in New Mexico.

In accounting terms, they’ll depreciate the value of their share of the plant to zero over the next nine years, reflecting what they say is the end of the plant’s “useful life.” Another of Colstrip’s owners, Puget Sound Energy, has previously agreed with Washington regulators that it’ll budget for a Colstrip closure in 2027 as well.

Avista and Hydro One will look for sources of 50 megawatts of renewable electricity, including independent power projects where feasible, in the next four years and another 90 megawatts to supplement Avista’s supply once the Colstrip plant eventually closes, they promise in Washington. They’ll put $3 million into a “community transition fund” for Colstrip.

The money will come from the companies’ profits and cash, the agreement says. “Hydro One will not seek cost recovery for such funds from ratepayers in Ontario,” it says specifically.

“Ontario has always been a global leader in the transition away from dirty coal power and towards clean energy,” said Doug Howell, an anti-coal campaigner with the Sierra Club, which is a party to the agreement. “This settlement continues that tradition, paving the way for the closure of the largest single source of climate pollution in the American West by 2027, if not earlier.”

Montanans aren’t as thrilled. That state has its own public services commission, doing its own examination of the corporate merger, which has asked Hydro One and Avista to explain in detail why they want to write off the value of the Colstrip burners early. The City of Colstrip has filed a petition saying it wants in on Montana hearings because “the potential closure of (Avista’s units) would be devastating to our community.”

Don’t get too worked up, an Avista vice-president urged the Montana commission just before Easter.

“Just because an asset is depreciated does not mean that one would otherwise remove that asset from service if the asset is still performing as intended,” Jason Thackston testified in a session that dealt only with what the deal with Washington state would mean to Colstrip. We’re talking strictly about an accounting manoeuvre, not an operational commitment.

Six joint owners will have to agree to close the Colstrip generators and there’s “no other tacit understanding or unstated agreement” to do that, he said.

Besides Washington and Montana, state regulators in Idaho, including those overseeing the Idaho Power settlement process, Alaska and Oregon and multiple federal authorities have to sign off on the deal before it can happen. Hydro One hopes it’ll be done in the second half of this year.

German coalition backs electricity subsidy for industries

Germany Industrial Electricity Price Subsidy weighs subsidies for energy-intensive industries to bolster competitiveness as Germany shifts to renewables, expands grid capacity, and debates free-market tax cuts versus targeted relief and long-term policies.

 

Key Points

Policy to subsidize power for energy-intensive industry, preserving competitiveness during the energy transition.

✅ SPD backs 5-7 cents per kWh for 10-15 years

✅ FDP prefers tax cuts and free-market pricing

✅ Scholz urges cheap renewables and grid expansion first

 

Germany’s three-party coalition is debating whether electricity prices for energy-intensive industries should be subsidised in a market where rolling back European electricity prices can be tougher than it appears, to prevent companies from moving production abroad.

Calls to reduce the electricity bill for big industrial producers are being made by leading politicians, who, like others in Germany, fear the country could lose its position as an industrial powerhouse as it gradually shifts away from fossil fuel-based production, amid historic low energy demand and economic stagnation concerns.

“It is in the interest of all of us that this strong industry, which we undoubtedly have in Germany, is preserved,” Lars Klingbeil, head of Germany’s leading government party SPD (S&D), told Bayrischer Rundfunk on Wednesday.

To achieve this, Klingbeil is advocating a reduced electricity price for the industry of about 5 to 7 cents per Kilowatt hour, which the federal government would subsidise. This should be introduced within the next year and last for about 10 to 15 years, he said.

Under the current support scheme, which was financed as part of the €200 billion “rescue shield” against the energy crisis, energy-intensive industries already pay 13 cents per Kilowatt hour (KWh) for 70% of their previous electricity needs, which is substantially lower than the 30 to 40 cents per KWh that private consumers pay.

“We see that the Americans, for example, are spending $450 billion on the Inflation Reduction Act, and we see what China is doing in terms of economic policy,” Klingbeil said.

“If we find out in 10 years that we have let all the large industrial companies slip away because the investments are not being made here in Germany or Europe, and jobs and prosperity and growth are being lost here, then we will lose as a country,” he added.

However, not everyone in the German coalition favours subsidising electricity prices.

Finance Minister Christian Lindner of the liberal FDP (Renew), for example, has argued against such a step, instead promoting free-market principles and, amid rising household energy costs, reducing taxes on electricity for all.

“Privileging industrial companies would only be feasible at the expense of other electricity consumers and taxpayers, for example, private households or the small trade sector,” Lindner wrote in an op-ed for Handelsblatt on Tuesday.

“Increasing competitiveness for some would mean a loss of competitiveness for others,” he added.

Chancellor Olaf Scholz, himself a member of SPD, was more careful with his words, amid ongoing EU electricity reform debates in Brussels.

Asked about a subsidised electricity price for the industry at a town hall event on Monday, Scholz said he does not “want to make any promises now”.

“First of all, we have to make sure that we have cheap electricity in Germany in the first place,” Scholz said, promoting the expansion of renewable energy such as wind and solar, as local utilities cry for help, as well as more electricity grid infrastructure.

“What we will not be able to do as an economy, even as France’s new electricity pricing scheme advances, is to subsidise everything that takes place in normal economic activity,” Scholz said. “We should not get into the habit of doing that,” he added.
