Xcel ditches coal plants to go solar

NB Power and Hydro-Québec Electricity Agreements expand clean hydroelectric exports, support Mactaquac dam refurbishment, add grid interconnections, and advance decarbonization, climate goals, reliability, and transmission capacity across Atlantic Canada and U.S. markets through 2040.

Key Points

Deals for hydro exports, Mactaquac upgrades, and new interconnections to improve reliability and cut emissions.

✅ 47 TWh to NB by 2040 over existing transmission lines

✅ HQ expertise to address Mactaquac concrete swelling

✅ Talks on new interconnections for Atlantic and U.S. exports

NB Power and Hydro-Quebec have signed three deals that will see Quebec sell more electricity to New Brunswick and provide help with the refurbishment of the Mactaquac hydroelectric generating station.

Under the first agreement, Hydro-Quebec will export 47 terawatt hours of electricity to New Brunswick between now and 2040 over existing power lines — expanding on an agreement in place since 2012 and on related regional agreements such as the Churchill Falls deal in Newfoundland and Labrador.

The second deal will see Hydro-Quebec share expertise for part of the refurbishment of the Mactaquac dam to extend the useful life of the generating station until at least 2068, when the 670 megawatt facility on the St. John River will be 100 years old.

Since the 1980s, concrete portions of the facility have been affected by a chemical reaction that causes the concrete to swell and crack.

Hydro-Quebec has been dealing with the same problem, and has developed expertise in addressing the issue.

“This is why we have signed a technical collaboration agreement between Hydro-Quebec and us for part of the refurbishment of the Mactaquac generating station,” NB Power president Gaetan Thomas said Friday.

Eric Martel, CEO of Hydro-Quebec, said hydroelectric plants provide long-term clean power that’s important in the fight against climate change as the province has ruled out nuclear power for now.

“We understand how important it is to ensure the long term sustainability of these facilities and we are happy to share the expertise that Hydro-Quebec has acquired over the years,” Martel said.

The refurbishment of the Mactaquac generating station is expected to cost between $2.9 billion and $3.5 billion. Once the work begins, each of the facility’s six generators will have to be taken offline for months at a time, and Thomas said that’s where the increased power from Quebec, supported by Hydro-Quebec's capacity expansion in recent years, will come into use.

He expects the power could cost about $100 million per year but will be much cheaper than other sources.

The third agreement calls for talks to begin for the construction of additional power connections between Quebec and New Brunswick to increase exports to Atlantic Canada and the United States, where transmission constraints have limited incremental deliveries in recent years.

“Building new interconnections and allowing for increased power transfer between our systems could be mutually beneficial, even as historic tensions in Newfoundland and Labrador linger. More than ever, we are looking to the future,” Martel said.

“Partnering will permit us to seize new business opportunities together and pool our effort to support de-carbonization, including Hydro-Quebec's non-fossil strategy that is now underway, and fight against climate change, both here and in our neighbourhood market,” he said.

B.C. EV Electrification 2055 projects grid capacity needs doubling to 37 GW, driven by electric vehicles, renewable energy expansion, wind and solar generation, limited natural gas, and policy mandates for zero-emission transportation.

Key Points

A projection that electrifying all B.C. road transport by 2055 would more than double grid demand to 37 GW.

✅ Site C adds 1.1 GW; rest from wind, solar, limited natural gas.

✅ Electricity price per kWh rises 9%, but fuel savings offset.

✅ Significant GHG cuts with 93% renewable grid under Clean Energy Act.

Researchers at the University of Victoria say that if B.C. were to shift to electric power for all road vehicles by 2055, the province would require more than double the electricity now being generated.

The findings are included in a study to be published in the November issue of the Applied Energy journal.

According to co-author and UVic professor Curran Crawford, the team at the university's Pacific Institute for Climate Solutions took B.C.'s 2015 electrical capacity of 15.6 gigawatts as a baseline, and added projected demands from population and economic growth, then added the increase that shifting to electric vehicles would require, while acknowledging power supply challenges that could arise.

They calculated the demand in 2055 would amount to 37 gigawatts, more than double 15.6 gigawatts used in 2015 as a baseline, and utilities warn of a potential EV charging bottleneck if demand ramps up faster than infrastructure.

"We wanted to understand what the electricity requirements are if you want to do that," he said. "It's possible — it would take some policy direction."

The team took the planned Site C dam project into account, but that would only add 1.1 gigawatts of power. So assuming no other hydroelectric dams are planned, the remainder would likely have to come from wind and solar projects and some natural gas.

"Geothermal and biomass were also in the model," said Crawford, adding that they are more expensive electricity sources. "The model we were using, essentially, we're looking for the cheapest options."

The electricity bill, per kilowatt hour, would increase by nine per cent, according to the team's research, but Crawford said getting rid of the gasoline and diesel now used to fuel vehicles could amount to an overall cost saving, especially when combined with zero-emission vehicle incentives available to consumers.

The province introduced a law this year requiring that all new light-duty vehicles sold in B.C. be zero emission by 2040, while the federal 2035 EV mandate adds another policy signal, so the researchers figured 2055 was a reasonable date to imagine all vehicles on the road to be electric.

Crawford said hydrogen-powered vehicles weren't considered in the study, as the model used was already complicated enough, but hydrogen fuel would actually require more electricity for the electrolysis, when compared to energy stored in batteries.

Electric vehicles are approaching a tipping point as faster charging becomes more available — here's why
The study also found that shifting to all-electric ground transportation in B.C. would also mean a significant decrease in greenhouse gas emissions, assuming the Clean Energy Act remains in place, which mandates that 93 per cent of grid electricity must come from renewable resources, whereas nationally, about 18 per cent of electricity still comes from fossil fuels, according to 2019 data. 

"Doing the electrification makes some sense — If you're thinking of spending some money to reduce carbon emissions, this is a pretty cost effective way of doing that," said Crawford.

Nuclear Waste Corrosion accelerates as stainless steel, glass, and ceramics interact in aqueous conditions, driving localized corrosion in repositories like Yucca Mountain, according to Nature Materials research on high-level radioactive waste storage.

Key Points

Degradation of waste forms and canisters from water-driven chemistry, causing accelerated, localized corrosion in storage.

✅ Stainless steel-glass contact triggers severe localized attack

✅ Ceramics and steel co-corrosion observed under aqueous conditions

✅ Yucca Mountain-like chemistry accelerates waste form degradation

The materials the United States and other countries plan to use to store high-level nuclear waste, even as utilities expand carbon-free electricity portfolios, will likely degrade faster than anyone previously knew because of the way those materials interact, new research shows.

The findings, published today in the journal Nature Materials (https://www.nature.com/articles/s41563-019-0579-x), show that corrosion of nuclear waste storage materials accelerates because of changes in the chemistry of the nuclear waste solution, and because of the way the materials interact with one another.

"This indicates that the current models may not be sufficient to keep this waste safely stored," said Xiaolei Guo, lead author of the study and deputy director of Ohio State's Center for Performance and Design of Nuclear Waste Forms and Containers, part of the university's College of Engineering. "And it shows that we need to develop a new model for storing nuclear waste."

Beyond waste storage, options like carbon capture technologies are being explored to reduce atmospheric CO2 alongside nuclear energy.

The team's research focused on storage materials for high-level nuclear waste -- primarily defense waste, the legacy of past nuclear arms production. The waste is highly radioactive. While some types of the waste have half-lives of about 30 years, others -- for example, plutonium -- have a half-life that can be tens of thousands of years. The half-life of a radioactive element is the time needed for half of the material to decay.

The United States currently has no disposal site for that waste; according to the U.S. General Accountability Office, it is typically stored near the nuclear power plants where it is produced. A permanent site has been proposed for Yucca Mountain in Nevada, though plans have stalled. Countries around the world have debated the best way to deal with nuclear waste; only one, Finland, has started construction on a long-term repository for high-level nuclear waste.

But the long-term plan for high-level defense waste disposal and storage around the globe is largely the same, even as the U.S. works to sustain nuclear power for decarbonization efforts. It involves mixing the nuclear waste with other materials to form glass or ceramics, and then encasing those pieces of glass or ceramics -- now radioactive -- inside metallic canisters. The canisters then would be buried deep underground in a repository to isolate it.

At the generation level, regulators are advancing EPA power plant rules on carbon capture to curb emissions while nuclear waste strategies evolve.

In this study, the researchers found that when exposed to an aqueous environment, glass and ceramics interact with stainless steel to accelerate corrosion, especially of the glass and ceramic materials holding nuclear waste.

In parallel, the electrical grid's reliance on SF6 insulating gas has raised warming concerns across Europe.

The study qualitatively measured the difference between accelerated corrosion and natural corrosion of the storage materials. Guo called it "severe."

"In the real-life scenario, the glass or ceramic waste forms would be in close contact with stainless steel canisters. Under specific conditions, the corrosion of stainless steel will go crazy," he said. "It creates a super-aggressive environment that can corrode surrounding materials."

To analyze corrosion, the research team pressed glass or ceramic "waste forms" -- the shapes into which nuclear waste is encapsulated -- against stainless steel and immersed them in solutions for up to 30 days, under conditions that simulate those under Yucca Mountain, the proposed nuclear waste repository.

Those experiments showed that when glass and stainless steel were pressed against one another, stainless steel corrosion was "severe" and "localized," according to the study. The researchers also noted cracks and enhanced corrosion on the parts of the glass that had been in contact with stainless steel.

Part of the problem lies in the Periodic Table. Stainless steel is made primarily of iron mixed with other elements, including nickel and chromium. Iron has a chemical affinity for silicon, which is a key element of glass.

The experiments also showed that when ceramics -- another potential holder for nuclear waste -- were pressed against stainless steel under conditions that mimicked those beneath Yucca Mountain, both the ceramics and stainless steel corroded in a "severe localized" way.

Other Ohio State researchers involved in this study include Gopal Viswanathan, Tianshu Li and Gerald Frankel.

This work was funded in part by the U.S. Department of Energy Office of Science.

Meanwhile, U.S. monitoring shows potent greenhouse gas declines confirming the impact of control efforts across the energy sector.

CCUS in the U.S. Power Sector drives investments as DOE grants, 45Q tax credits, and EPA carbon rules spur carbon capture, geologic storage, and utilization, while debates persist over costs, transparency, reliability, and emissions safeguards.

Key Points

CCUS captures CO2 from power plants for storage or use, backed by 45Q tax credits, DOE funding, and EPA carbon rules.

✅ DOE grants and 45Q credits aim to de-risk project economics.

✅ EPA rules may require capture rates to meet emissions limits.

✅ Transparency and MRV guard against tax credit abuse.

New public and private funding, including DOE $110M for CCUS announced recently, and expected strong federal power plant emissions reduction standards have accelerated electricity sector investments in carbon capture, utilization and storage,’ or CCUS, projects but some worry it is good money thrown after bad.

CCUS separates carbon from a fossil fuel-burning power plant’s exhaust through carbon capture methods for geologic storage or use in industrial and other applications, according to the Department of Energy. Fossil fuel industry giants like Calpine and Chevron are looking to take advantage of new federal tax credits and grant funding for CCUS to manage potentially high costs in meeting power plant performance requirements, amid growing investor pressure for climate reporting, including new rules, expected from EPA soon, on reducing greenhouse gas emissions from existing power plants.

Power companies have “ambitious plans” to add CCUS to power plants, estimated to cause 25% of U.S. CO2 emissions. As a result, the power sector “needs CCUS in its toolkit,” said DOE Office of Fossil Energy and Carbon Management Assistant Secretary Brad Crabtree. Successful pilots and demonstrations “will add to investor confidence and lead to more deployment” to provide dispatchable clean energy, including emerging CO2-to-electricity approaches for power system reliability after 2030,| he added.

But environmentalists and others insist potentially cost-prohibitive CCUS infrastructure, including CO2 storage hub initiatives, must still prove itself effective under rigorous and transparent federal oversight.

“The vast majority of long-term U.S. power sector needs can be met without fossil generation, and better options are being deployed and in development,” Sierra Club Senior Advisor, Strategic Research and Development, Jeremy Fisher, said, pointing to carbon-free electricity investments gaining momentum in the market. CCUS “may be needed, but without better guardrails, power sector abuses of federal funding could lead to increased emissions and stranded fossil assets,” he added.

New DOE CCUS project grants, an increased $85 per metric ton, or tonne, federal 45Q tax credit, and the forthcoming EPA power plant carbon rules and the federal coal plan will do for CCUS what similar policies did for renewables, advocates and opponents agreed. But controversial past CCUS performance and tax credit abuses must be avoided with transparent reporting requirements for CO2 capture, opponents added.

Pacific Northwest Transmission Bottleneck slows clean energy progress as BPA's aging grid constrains renewable interconnections, delaying wind, solar, and data center growth; decarbonization targets depend on transmission upgrades, new substations, and policy reform.

Key Points

An interconnection and capacity shortfall on BPA's aging grid that delays renewables and impedes clean energy goals.

✅ BPA approvals lag: 1 of 469 projects since 2015.

✅ Yakama solar waits for substation upgrades until 2027.

✅ Data centers and decarbonization targets face grid constraints.

Oregon and Washington have set ambitious targets to decarbonize their power sectors, aiming for 100% clean electricity in the coming decades. However, a significant obstacle stands in the way: the region's aging and overburdened transmission grid, underscoring why 100% renewables remain elusive even as momentum builds.

The Grid Bottleneck

The BPA operates a transmission system that is nearly a century old in some areas, and its capacity has not expanded sufficiently to accommodate the influx of renewable energy projects, reflecting stalled grid spending in many parts of the U.S., according to recent analyses. Since 2015, 469 large renewable projects have applied to connect to the BPA's grid; however, only one has been approved—a stark contrast to other regions in the country. This bottleneck has left numerous wind and solar projects in limbo, unable to deliver power to the grid.

One notable example is the Yakama Nation's solar project. Despite receiving a $32 million federal grant under the bipartisan infrastructure law as part of a broader grid overhaul for renewables, the tribe faces significant delays. The BPA estimates that it will take until 2027 to complete the necessary upgrades to the transmission system, including a new substation, before the solar array can be connected. This timeline poses a risk of losing federal funding if the project isn't operational by 2031.

Economic and Environmental Implications

The slow pace of grid expansion has broader implications for the region's economy and environmental goals. Data centers and other energy-intensive industries are increasingly drawn to the Pacific Northwest due to its clean energy potential, while interregional projects like the Wyoming-to-California wind link illustrate how transmission access can unlock supply. However, without adequate infrastructure, these industries may seek alternatives elsewhere. Additionally, the inability to integrate renewable energy efficiently hampers efforts to reduce greenhouse gas emissions and combat climate change.

Policy Challenges and Legislative Efforts

Efforts to address the grid limitations through state-level initiatives have faced challenges, even as a federal rule to boost transmission advances nationally. In 2025, both Oregon and Washington considered legislation to establish state bonding authorities aimed at financing transmission upgrades. However, these bills failed to pass, leaving the BPA as the primary entity responsible for grid expansion. The BPA's unique structure—operating as a self-funded federal agency without direct state oversight—has made it difficult for regional leaders to influence its decision-making processes.

Looking Ahead

The Pacific Northwest's renewable energy aspirations hinge on modernizing its transmission infrastructure, aligning with decarbonization strategies that emphasize grid buildout. While the BPA has proposed several projects to enhance grid capacity, the timeline for completion remains uncertain. Without significant investment and policy reforms, the region risks falling behind in the transition to a clean energy future. Stakeholders across Oregon and Washington must collaborate to advocate for necessary changes and ensure that the grid can support the growing demand for renewable energy.

The Pacific Northwest's commitment to clean energy is commendable, but achieving these goals requires overcoming substantial infrastructure challenges, and neighboring jurisdictions such as British Columbia have pursued B.C. regulatory streamlining to accelerate projects. Addressing the limitations of the BPA's transmission system is critical to unlocking the full potential of renewable energy in the region. Only through concerted efforts at the federal, state, and local levels can Oregon and Washington hope to realize their green energy ambitions.

Canada Clean Electricity Regulations align climate policy with grid reliability, scaling renewables, energy storage, and low-carbon power to reach net-zero by 2050 while maintaining affordability through federal incentives, provincial flexibility, and investment.

Key Points

Nationwide rules to decarbonize power by 2050, capping emissions and protecting grid reliability and affordability.

✅ Net-zero electricity by 2050 with strict emissions limits

✅ Provincial flexibility and federal investments to cut costs

✅ Scales renewables, storage, and clean firm power for reliability

Canada's final Clean Electricity Regulations, unveiled in December 2024, alongside complementary provincial frameworks such as Ontario's clean electricity regulations that guide provincial implementation, represent a critical step toward ensuring a sustainable and reliable energy future. With electricity demand set to rise as the country’s population and economy grow, the Canadian government has put forward a robust plan that balances climate goals with the need for reliable, affordable power.

The regulations are designed to reduce greenhouse gas emissions from the electricity sector, which is already one of Canada's cleanest, with 85% of its electricity sourced from renewable energies like hydro, wind, and solar, and growing attention to clean grids and batteries nationwide. The target is to achieve net-zero emissions in electricity generation by 2050, a goal that will support the country’s broader climate ambitions.

One of the central goals of the Clean Electricity Regulations is to make sure that Canada’s power grid can accommodate future demand in light of a critical electrical supply crunch identified by analysts, while ensuring that emissions are cut effectively. The regulations set strict pollution limits but allow flexibility for provinces and territories to meet these goals in ways that suit their local circumstances. This approach recognizes the diverse energy resources across Canada, from the large-scale hydroelectric capacity in Quebec to the growing wind and solar projects in the West.

A key benefit of these regulations is the assurance that they will not result in higher electricity rates for most Canadians. In fact, according to government analyses, and resources like the online CER bill tool that explain how fees and usage affect charges, the regulations are expected to have a neutral or even slightly positive impact on electricity costs. This is due in part to significant federal investments in the electricity sector, totaling over $60 billion. These investments are intended to support the transition to clean electricity while minimizing costs for consumers.

The shift to clean electricity is also expected to generate significant savings for Canadian households. As energy prices continue to fluctuate, clean electricity, especially from renewable sources, is becoming more cost-competitive compared to fossil fuels. Over the next decade, this transition is expected to result in $15 billion in total savings for Canadians, with 84% of households projected to benefit from lower energy bills. The savings are a result of federal incentives aimed at encouraging the adoption of efficient electric appliances, vehicles, and heating systems.

Moreover, reducing emissions from the electricity sector will play a major role in cutting Canada’s overall greenhouse gas pollution. By 2050, it’s estimated that these regulations will reduce nearly 181 megatonnes of emissions, which is equivalent to removing over 55 million cars from the road. This is a crucial step in meeting Canada’s climate targets and mitigating the impacts of climate change, such as extreme weather events, which have already led to significant economic losses.

The economic benefits extend beyond savings on energy bills. The regulations and the broader clean electricity strategy will create substantial job opportunities. The clean energy sector, which includes jobs in wind, solar, and nuclear power, is poised for massive growth, and provinces like Alberta have outlined a path to clean electricity to support that momentum. It’s estimated that by 2030, the transition to clean electricity could create 400,000 new jobs, with further job growth projected for the years to come. These jobs are expected to include roles in both the construction and operation of new energy infrastructure, many of which will be unionized positions offering good wages and benefits.

To help meet the rising demand for clean energy, the government’s strategy emphasizes technological innovation and the integration of new energy sources, including market design updates such as proposed market changes that can enable investment. Renewable energy technologies such as wind and solar power have become increasingly cost-competitive, and their continued development is expected to reduce the overall cost of electricity generation. The regulations also encourage the adoption of energy storage solutions, which are essential for managing the intermittent nature of renewable energy sources.

In addition to the environmental and economic benefits, the Clean Electricity Regulations will help improve public health. Air pollution from fossil fuel power generation is a major contributor to respiratory illnesses and other health issues. By transitioning to clean energy sources, Canada can reduce harmful air pollutants, leading to better health outcomes and a lower burden on the healthcare system.

As Canada moves toward a net-zero electricity grid, including the federal 2035 target that some have criticized as changing goalposts in Saskatchewan, the Clean Electricity Regulations represent a comprehensive and flexible approach to managing the energy transition. With significant investments in clean energy technologies and the adoption of policies that ensure affordable electricity for all Canadians, the government is setting the stage for a cleaner, more sustainable future. These efforts will not only help Canada meet its climate goals but also create a thriving clean energy economy that benefits workers, businesses, and families across the country.
