The reliability and security of Manitoba's electricity supply recently received a boost with the completion of Manitoba Hydro's new Riel Terminal Station just east of Winnipeg.

Riel will improve the reliability of the transmission system serving Winnipeg and southern Manitoba by providing a second location where electricity imported from the United States on an existing 500,000-volt transmission line can be fed into Manitoba Hydro's power grid.

"The transmission line to the U.S. is an important piece of Manitoba Hydro's system - it delivers surplus electricity to the U.S., and provides access to an alternate supply of energy in the event of an emergency or prolonged drought," said Scott Thomson, President and CEO, Manitoba Hydro. "With the energizing of Riel, we now have a second point where we can inject electricity from the U.S. into our system, helping ensure energy will be there when we need it."

The 500,000-volt transmission line runs from Dorsey Station, northwest of Winnipeg, to Minnesota. Construction of Riel began after studies concluded it was necessary to reduce dependence on the existing end-point of the line at Dorsey. Those studies were conducted after a major windstorm in September 1996 severely damaged 19 towers on Manitoba Hydro's high voltage direct current HVDC lines north of Dorsey, adjacent to the Dorsey-Minnesota transmission line.

The Riel Terminal Station came in on schedule at a cost of $330 million.

Duke Energy will spend US$25bn to modernise its US grid

Duke Energy Clean Energy Strategy targets smart grid upgrades, wind and solar expansion, efficient gas, and high-reliability nuclear, cutting CO2, boosting decarbonization, and advancing energy efficiency and reliability for the Carolinas.

 

Key Points

A plan investing in smart grids, renewables, gas, and nuclear to cut CO2 and enhance reliability and efficiency by 2030.

✅ US$25bn smart grid upgrades; US$11bn renewables and gas

✅ 40% CO2 reduction and >80% low-/zero-carbon generation by 2030

✅ 2017 nuclear fleet 95.64% capacity factor; ~90 TWh carbon-free

 

The US power group Duke Energy plans to invest US$25bn on grid modernization over the 2017-2026 period, including the implementation of smart grid technologies to cope with the development of renewable energies, along with US$11bn on the expansion of renewable (wind and solar) and gas-fired power generation capacities.

The company will modernize its fleet and expects more than 80% of its power generation mix to come from zero and lower CO2 emitting sources, aligning with nuclear and net-zero goals, by 2030. Its current strategy focuses on cutting down CO2 emissions by 40% by 2030. Duke Energy will also promote energy efficiency and expects cumulative energy savings - based on the expansion of existing programmes - to grow to 22 TWh by 2030, i.e. the equivalent to the annual usage of 1.8 million households.

Duke Energy’s 11 nuclear generating units posted strong operating performance in 2017, as U.S. nuclear costs hit a ten-year low, providing the Carolinas with nearly 90 billion kilowatt-hours of carbon-free electricity – enough to power more than 7 million homes.

Globally, China's nuclear program remains on a steady development track, underscoring broader industry momentum.

“Much of our 2017 success is due to our focus on safety and work efficiencies identified by our nuclear employees, along with ongoing emphasis on planning and executing refueling outages to increase our fleet’s availability for producing electricity,” said Preston Gillespie, Duke Energy chief nuclear officer.

Some of the nuclear fleet’s 2017 accomplishments include, as a new U.S. reactor comes online nationally:

  • The 11 units achieved a combined capacity factor of 95.64 percent, second only to the fleet’s 2016 record of 95.72 percent, marking the 19th consecutive year of attaining a 90-plus percent capacity factor (a measure of reliability).
  • The two units at Catawba Nuclear Station produced more than 19 billion kilowatt-hours of electricity, and the single unit at Harris Nuclear Plant generated more than 8 billion kilowatt-hours, both setting 12-month records.
  • Brunswick Nuclear Plant unit 2 achieved a record operating run.
  • Both McGuire Nuclear Station units completed their shortest refueling outages ever and unit 1 recorded its longest operating run.
  • Oconee Nuclear Station unit 2 achieved a fleet record operating run.

The Robinson Nuclear Plant team completed the station’s 30th refueling outage, which included a main generator stator replacement and other life-extension activities, well ahead of schedule.

“Our nuclear employees are committed to providing reliable, clean electricity every day for our Carolinas customers,” added Gillespie. “We are very proud of our team’s 2017 accomplishments and continue to look for additional opportunities to further enhance operations.”

California scorns fossil fuel but can't keep the lights on without it

California fossil fuel grid reliability plan addresses heat wave demand, rolling blackouts, and grid stability by temporarily procuring gas generation while accelerating renewables, storage, and transmission to meet clean energy and carbon-neutral targets by 2045.

 

Key Points

A stop-gap policy to prevent blackouts by buying fossil power while fast-tracking renewables, storage, and grid upgrades.

✅ Temporary procurement of gas to avoid rolling blackouts

✅ Accelerates renewables, storage, transmission permitting

✅ Aims for carbon neutrality by 2045 without new gas plants

 

California wants to quit fossil fuels. Just not yet Faced with a fragile electrical grid and the prospect of summertime blackouts, the state agreed to put aside hundreds of millions of dollars to buy power from fossil fuel plants that are scheduled to shut down as soon as next year.

That has prompted a backlash from environmental groups and lawmakers who say Democratic Gov. Gavin Newsom’s approach could end up extending the life of gas plants that have been on-track to close for more than a decade and could threaten the state’s goal to be carbon neutral by 2045.

“The emphasis that the governor has been making is ‘We’re going to be Climate Leaders; we’re going to do 100 percent clean energy; we’re going to lead the nation and the world,’” said V. John White, executive director of the Sacramento-based Center for Energy Efficiency and Renewable Technologies, a non-profit group of environmental advocates and clean energy companies. “Yet, at least a part of this plan means going the opposite direction.”

That plan was a last-minute addition to the state’s energy budget, which lawmakers in the Democratic-controlled Legislature reluctantly passed. Backers say it’s necessary to avoid the rolling blackouts like the state experienced during a heat wave in 2020. Critics see a muddled strategy on energy, and not what they expected from a nationally ambitious governor who has made climate action a centerpiece of his agenda.

The legislation, which some Democrats labeled as “lousy” and “crappy,” reflects the reality of climate change. Heat waves are already straining power capacity, and the transition to cleaner energy isn’t coming fast enough to meet immediate needs in the nation’s most populous state.

Officials have warned that outages would be possible this summer, as the grid faces heat wave tests again, with as many as 3.75 million California homes losing power in a worst-case scenario of a West-wide heat wave and insufficient electrical supplies, particularly in the evenings.

It’s also an acknowledgment of the political reality that blackout politics are hazardous to elected officials, even in a state dominated by one party.

Newsom emphasized that the money to prop up the power grid, part of a larger $4.3 billion energy spending package, is meant as a stop-gap measure. The bill allows the Department of Water Resources to spend $2.2 billion on “new emergency and temporary generators, new storage systems, clean generation projects, and funding on extension of existing generation operations, if any occur,” the governor said in a statement after signing the bill.

“Action is needed now to maintain reliable energy service as the State accelerates the transition to clean energy,” Newsom said.

Following the signing, the governor called for the state California Air Resources Board to add a set of ambitious goals to its 2022 Scoping Plan, which lays out California’s path for reducing carbon emissions.

Among Newsom’s requested changes is a move away from fossil fuels, asking state agencies to prepare for an energy transition that avoids the need for new natural gas plants.

Alex Stack, a spokesman for the governor, said in a statement that California has been a global leader in reducing pollution and exporting energy policies across Western states, and pointed to Newsom’s recent letter to the Air Resources Board as well as one sent to President Joe Biden outlining how states can work with the federal government to combat climate change.

“California took action to streamline permitting for clean energy projects to accelerate the build out of clean energy that is needed to meet our climate goals and help maintain reliability in the face of extreme heat, wildfires, and drought,” Stack said.

But the prospect of using state money on fossil fuel power, even in the short term, has raised ire among the state’s many environmental advocacy groups, and raised questions about whether California will be able to achieve its goals.

“What is so frustrating about an energy bill like this is that we are at crunch time to meet these goals,” said Mary Creasman, CEO of California Environmental Voters. “And we’re investing a scale of funding into things that exacerbate those goals.”

With climate change-induced drought and high temperatures continuing to ravage the West, California anticipates the demand on the grid will only continue to grow. Despite more than a decade of bold posturing and efforts to transition to solar, wind and hydropower, the state worries it doesn’t have enough renewable energy sources on hand to keep the power on in an emergency right now, amid a looming shortage that will test reliability.

The specter of power outages poses a hazard to Newsom, and Democrats in general, especially ahead of November. While the governor is widely expected to sail to reelection, rolling blackouts are a serious political liability — in 2003, they were the catalyst for recalling Democratic Gov. Gray Davis. A lack of power isn’t just about people sweating in the dark, said Steven Maviglio, a longtime Democratic consultant who served as communications director for Davis, it can affect businesses, travel and have an outsized impact on the economy.

It behooves any state official to keep the power on, but, unlike Davis, Newsom is under serious pressure to make sure the state also adheres to its climate goals.

“Gavin Newsom’s brand is based on climate change and clean air, so it’s a little more difficult for him to say ‘well that’s not as important as keeping the power on,’” Maviglio said.

The same bill effectively ends local government control over those projects, for the time being. It hopes to speed up the state’s production of renewable energy sources by giving exclusive authority over the siting of those projects to a single state agency for the next seven years.

Environmental advocates say the state is now scrambling to address an issue they’ve long known was coming. In 2010, California officials set a schedule to retire a number of coastal gas plants that rely on what’s known as once-through cooling systems, which are damaging to the environment, especially marine life, even as regulators weigh more power plants to maintain reliability today. Many of those plants have been retired since 2010, but others have received extensions.

The remaining plants have various deadlines for when they must cease operations, with the soonest being the end of 2023.

Also at issue is the embattled Diablo Canyon nuclear power plant, California’s largest electricity source. The Pacific Gas & Electric-owned plant is scheduled to close in 2025, but the strain on the grid has officials considering the possibility of seeking an extension. Newsom said earlier this spring he would be open to extending the life of the plant. Doing so would also require federal approval.

The International Brotherhood of Electrical Workers 1245, a labor union, sees the energy package as a way to preserve Diablo Canyon, and jobs at the plant.

“The value to 1245 PG&E members at Diablo Canyon is clear — funding to keep the plant open,” the union said of the bill.

Assemblymember Al Muratsuchi (D-Los Angeles) criticized the bill as “crappy” when it came to the floor in late June, describing it as “a rushed, unvetted and fossil-fuel-heavy response” to the state’s need to bolster the grid.

“The state has had over 12 years to procure and bring online renewable energy generation to replace these once through cooling gas power plants,” Muratsuchi said. “Yet, the state has reneged on its promise to shut down these plants, not once, but twice already.”

Not all details of the state’s energy budget are final. Lawmakers still have $3.8 billion to allocate when they return on Aug. 1 for the final stretch of the year.

Creasman, at California Environmental Voters, said she wants lawmakers to set specific guidelines for how and where it will spend the $2.2 billion when they return in August to dole out the remaining money in the budget. Newsom and legislators also need to ensure that this is the last time California has to spend money on fossil fuel, she said.

“Californians deserve to see what the plan is to make sure we’re not in this position again of having to choose between making climate impacts worse or keeping our lights on,” Creasman said. “That’s a false choice.”

Electricity Payouts on Biggest U.S. Grid Fall 64 Per Cent in Auction

PJM Capacity Auction Price Drop signals PJM Interconnection capacity market shifts, with $50/MW-day clearing, higher renewables and nuclear participation, declining coal, natural gas pressure, and zone impacts in ComEd and EMAAC, amid 21% reserve margins.

 

Key Points

A decline to $50 per MW-day in PJM capacity prices, shifting resource mix, zonal rates, and reserve margins.

✅ Clearing price fell to $50/MW-day from $140 in 2018

✅ Renewables and nuclear up; coal units down across PJM

✅ Zonal prices: ComEd $68.96, EMAAC $97.86; 21% reserves

 

Power-plant owners serving the biggest U.S. grid will be paid 64% less next year for being on standby to keep the lights on from New Jersey to Illinois.

Suppliers to PJM Interconnection LLC’s grid, which serves more than 65 million people, will get $50 a megawatt-day to provide capacity for the the year starting June 2022, according to the results of an auction released Wednesday. That’s down sharply from $140 in the previous auction, held in 2018. Analysts had expected the price would fall to about $85.

“Renewables, nuclear and new natural gas generators saw the greatest increases in cleared capacity, while coal units saw the largest decrease,” PJM said in a statement.

The PJM auction is the single most important event for power generators across the eastern U.S., including Calpine Corp., NRG Energy Inc. and Exelon Corp., because it dictates a big chunk of their future revenue. It also plays a pivotal role in shaping the region’s electricity mix, determining how much the region is willing to stick with coal and natural gas plants or replace them with wind and solar even as the aging grid complicates progress nationwide.

The results showed that the capacity price for the Chicago-area zone, known as ComEd, was $68.96 compared with $195.55 in the last auction. The price for the Pennsylvania and New Jersey zone, known as EMAAC, fell to $97.86 percent, from $165.73. All told, 144,477 megawatts cleared, representing a reserve margin of 21%.

Exelon shares fell 0.4% after the results were released. Vistra fell 1.5%. NRG was unchanged.

Blackouts triggered by extreme weather in Texas and California over the last year have reignited a debate over whether other regions should institute capacity systems similar to the one used by PJM, and whether to adopt measures like emergency fuel stock programs in New England as well. The market, which pays generators to be on standby in case extra power is needed, has long been a source of controversy. While it makes the grid more reliable, the system drives up costs for consumers. In the area around Chicago, for instance, these charges total more than $1.7 billion per year, accounting for 20% of customer bills, according to the Illinois Clean Jobs Coalition.

In the 2018 auction, PJM contracted supplies that were about 22% in excess of the peak demand projection at the time. This year, the grid is projected to start summer with a reserve margin of about 26%, as COVID-19 demand shifts persist, according to the market monitor -- far higher than the 16% most engineers say is needed to prevent major outages.

“This certainly doesn’t seem fair to ratepayers,” said Ari Peskoe, director of Harvard Law School’s Electricity Law Initiative.

Fossil-Fuel Advantage
Heading into the auction, analysts expected coal and gas plants to have the advantage. Nuclear reactors and renewables, they said, were poised to struggle amid coal and nuclear disruptions nationwide.

That’s because this is the first PJM auction run under a major pricing change imposed by federal regulators during the Trump administration. The new structure creates a price floor for some bidders, effectively hobbling nuclear and renewables that receive state subsidies while making it easier for fossil fuels to compete.

Those rules triggered contentious wrangling between power providers, PJM and federal regulators, delaying the auction for two years. The new system, however, may be short lived. The Biden administration is moving to overhaul the rules in time for the next auction in December.

Dominion Energy Inc., one of the biggest U.S. utility owners, pulled out of the market over the rules. The Virginia-based company, which has a goal to have net-zero carbon emissions by 2050, said the new PJM format will “make renewables more expensive” than delivering clean energy through alternative markets.

Illinois, New Jersey and Maryland have also threatened to leave the capacity market unless the new price floor is eliminated, and Connecticut is leading a market overhaul in New England as well. PJM has already launched a process to do it.

PJM is already one of the most fossil-fuel intensive grids, with 60% of its electricity coming from coal and gas. Power plants that bid into the auction rely on it for the bulk of their revenue. That means plants that win contracts have an incentive to continue operating for as long as they can, even amid a supply-chain crisis this summer.

Germany - A needed nuclear option for climate change

Germany Nuclear Debate Amid Energy Crisis highlights nuclear power vs coal and natural gas, renewables and hydropower limits, carbon emissions, energy security, and baseload reliability during Russia-related supply shocks and winter demand.

 

Key Points

Germany Nuclear Debate Amid Energy Crisis weighs reactor extensions vs coal revival to bolster security, curb emissions.

✅ Coal plants restarted; nuclear shutdown stays on schedule.

✅ Energy security prioritized amid Russian gas supply cuts.

✅ Emissions likely rise despite renewables expansion.

 

Peel away the politics and the passion, the doomsaying and the denialism, and climate change largely boils down to this: energy. To avoid the chances of catastrophic climate change while ensuring the world can continue to grow — especially for poor people who live in chronically energy-starved areas — we’ll need to produce ever more energy from sources that emit little or no greenhouse gases.

It’s that simple — and, of course, that complicated.

Zero-carbon sources of renewable energy like wind and solar have seen tremendous increases in capacity and equally impressive decreases in price in recent years, while the decades-old technology of hydropower is still what the International Energy Agency calls the “forgotten giant of low-carbon electricity.”

And then there’s nuclear power. Viewed strictly through the lens of climate change, nuclear power can claim to be a green dream, even as Europe is losing nuclear power just when it really needs energy most.

Unlike coal or natural gas, nuclear plants do not produce direct carbon dioxide emissions when they generate electricity, and over the past 50 years they’ve reduced CO2 emissions by nearly 60 gigatonnes. Unlike solar or wind, nuclear plants aren’t intermittent, and they require significantly less land area per megawatt produced. Unlike hydropower — which has reached its natural limits in many developed countries, including the US — nuclear plants don’t require environmentally intensive dams.

As accidents at Chernobyl and Fukushima have shown, when nuclear power goes wrong, it can go really wrong. But newer plant designs reduce the risk of such catastrophes, which themselves tend to garner far more attention than the steady stream of deaths from climate change and air pollution linked to the normal operation of conventional power plants.

So you might imagine that those who see climate change as an unparalleled existential threat would cheer the development of new nuclear plants and support the extension of nuclear power already in service.

In practice, however, that’s often not the case, as recent events in Germany underline.

When is a Green not green?
The Russian war in Ukraine has made a mess of global energy markets, but perhaps no country has proven more vulnerable than Germany, reigniting debate over a possible resurgence of nuclear energy in Germany among policymakers.

At the start of the year, Russian exports supplied more than half of Germany’s natural gas, along with significant portions of its oil and coal imports. Since the war began, Russia has severely curtailed the flow of gas to Germany, putting the country in a state of acute energy crisis, with fears growing as next winter looms.

With little natural gas supplies of the country’s own, and its heavily supported renewable sector unable to fully make up the shortfall, German leaders faced a dilemma. To maintain enough gas reserves to get the country through the winter, they could try to put off the closure of Germany’s last three remaining nuclear reactors temporarily, which were scheduled to shutter by the end of 2022 as part of Germany’s post-Fukushima turn against nuclear power, and even restart already closed reactors.

Or they could try to reactivate mothballed coal-fired power plants, and make up some of the electricity deficit with Germany’s still-ample coal reserves.

Based on carbon emissions alone, you’d presumably go for the nuclear option. Coal is by far the dirtiest of fossil fuels, responsible for a fifth of all global greenhouse gas emissions — more than any other single source — as well as a soup of conventional air pollutants. Nuclear power produces none of these.

German legislators saw it differently. Last week, the country’s parliament, with the backing of members of the Green Party in the coalition government, passed emergency legislation to reopen coal-powered plants, as well as further measures to boost the production of renewable energy. There would be no effort to restart closed nuclear power plants, or even consider a U-turn on the nuclear phaseout for the last active reactors.

“The gas storage tanks must be full by winter,” Robert Habeck, Germany’s economy minister and a member of the Green Party, said in June, echoing arguments that nuclear would do little to solve the gas issue for the coming winter.

Partially as a result of that prioritization, Germany — which has already seen carbon emissions rise over the past two years, missing its ambitious emissions targets — will emit even more carbon in 2022.

To be fair, restarting closed nuclear power plants is a far more complex undertaking than lighting up old coal plants. Plant operators had only bought enough uranium to make it to the end of 2022, so nuclear fuel supplies are set to run out regardless.

But that’s also the point. Germany, which views itself as a global leader on climate, is grasping at the most carbon-intensive fuel source in part because it made the decision in 2011 to fully turn its back on nuclear for good at the time, enshrining what had been a planned phase-out into law.

Energy Vault Secures $28M for California Green Hydrogen Microgrid

Calistoga Resiliency Centre Microgrid delivers grid resilience via green hydrogen and BESS, providing island-mode backup during PSPS events, wildfire risk, and outages, with black-start and grid-forming capabilities for reliable community power.

 

Key Points

A hybrid green hydrogen and BESS facility ensuring resilient, islanded power for Calistoga during PSPS and outages.

✅ 293 MWh capacity with 8.5 MW peak for critical backup

✅ Hybrid lithium-ion BESS plus green hydrogen fuel cells

✅ Island mode with black-start and grid-forming support

 

Energy Vault, a prominent energy storage and technology company known for its gravity storage, recently secured US$28 million in project financing for its innovative Calistoga Resiliency Centre (CRC) in California. This funding will enable the development of a microgrid powered by a unique combination of green hydrogen and battery energy storage systems (BESS), marking a significant step forward in enhancing grid resilience in the face of natural disasters such as wildfires.

Located in California's fire-prone regions, the CRC is designed to provide critical backup power during Public Safety Power Shutoff (PSPS) events—periods when utility companies proactively cut power to prevent wildfires. These events can leave communities without electricity for extended periods, making the need for reliable, independent power sources more urgent as many utilities see benefits in energy storage today. The CRC, with a capacity of 293 MWh and a peak output of 8.5 MW, will ensure that the Calistoga community maintains power even when the grid is disconnected.

The CRC features an integrated hybrid system that combines lithium-ion batteries and green hydrogen fuel cells, even as some grid-scale projects adopt vanadium flow batteries for long-duration needs. During a PSPS event or other grid outages, the system will operate in "island mode," using hydrogen to generate electricity. This setup not only guarantees power supply but also contributes to grid stability by supporting black-start and grid-forming functions. Energy Vault's proprietary B-VAULT DC battery technology complements the hydrogen fuel cells, enhancing the overall performance and resilience of the microgrid.

One of the key aspects of the CRC project is the utilization of green hydrogen. Unlike traditional hydrogen, which is often produced using fossil fuels, green hydrogen is generated through renewable energy sources like solar or wind power, with large-scale initiatives such as British Columbia hydrogen project accelerating supply, making it a cleaner and more sustainable alternative. This aligns with California’s ambitious clean energy goals and is expected to reduce the carbon footprint of the region’s energy infrastructure.

The CRC project also sets a precedent for future hybrid microgrid deployments across California and other wildfire-prone areas, with utilities like SDG&E Emerald Storage highlighting growing adoption. Energy Vault has positioned the CRC as a model for scalable, utility-scale microgrids that can be adapted to various locations facing similar challenges. Following the success of this project, Energy Vault is expanding its portfolio with additional projects in Texas, where it anticipates securing up to US$25 million in financing.

The funding for the CRC also includes the sale of an investment tax credit (ITC), a key component of the financing structure that helps make such ambitious projects financially viable. This structure is crucial as it allows companies to leverage government incentives to offset development costs, including CEC long-duration storage funding, thus encouraging further investment in green energy infrastructure.

Despite some skepticism regarding the transportation of hydrogen rather than producing it onsite, the project has garnered strong support. California’s Public Utilities Commission (CPUC) acknowledged the potential risks of transporting green hydrogen but emphasized that it is still preferable to using more harmful fuel sources. This recognition is important as it validates Energy Vault’s approach to using hydrogen as part of a broader strategy to transition to clean, reliable energy solutions.

Energy Vault's shift from its traditional gravity-based energy storage systems to battery energy storage systems, such as BESS in New York, reflects the company's adaptation to the growing demand for versatile, efficient energy solutions. The hybrid approach of combining BESS with green hydrogen represents an innovative way to address the challenges of energy storage, especially in regions vulnerable to natural disasters and power outages.

As the CRC nears mechanical completion and aims for full commercial operations by Q2 2025, it is poised to become a critical part of California’s grid resilience strategy. The microgrid's ability to function autonomously during emergencies will provide invaluable benefits not only to Calistoga but also to other communities that may face similar grid disruptions in the future.

Energy Vault’s US$28 million financing for the Calistoga Resiliency Centre marks a significant milestone in the development of hybrid microgrids that combine the power of green hydrogen and battery energy storage. This project exemplifies the future of energy resilience, showcasing a forward-thinking approach to mitigating the impact of natural disasters and ensuring a reliable, sustainable energy future for communities at risk. With its innovative use of renewable energy sources and cutting-edge technology, the CRC sets a strong example for future energy storage projects worldwide.
