KUB looks at peak power demand

V.C. Summer nuclear plant leak update: Dominion Energy repaired a valve in the reactor cooling system; radioactive water stayed within containment, NRC oversight continues as power output ramps toward full operation.

Key Points

A minor valve leak in the reactor cooling system contained onsite; Dominion repaired it as the plant resumes power.

✅ Valve leak in piping to steam generators, not environmental release.

✅ Radioactive water remained in containment, monitored per NRC rules.

✅ Plant ramping from 17% power; full operations may take days.

The V.C. Summer nuclear power plant, which has been shut down since early November because of a pipe leak, is expected to begin producing energy in a few days, a milestone comparable to a new U.S. reactor startup reported recently.

Dominion Energy says it has fixed the small leak in a pipe valve that allowed radioactive water to drip out. The company declined to say when the plant would be fully operational, but spokesman Ken Holt said that can take several days, amid broader discussions about the stakes of early nuclear closures across the industry.

The plant was at 17 percent power Wednesday, he said, as several global nuclear project milestones continue to be reported this year.

Holt, who said Dominion is still investigating the cause, said water that leaked was part of the reactor cooling system. While the water came in contact with nuclear fuel in the reactor, the water never escaped the plant's containment building and into the environment, Holt said.

He characterized the valve leak as '"uncommon" but not unexpected. The nuclear leak occurred in piping that links the nuclear reactor with the power plant's steam generators. Hundreds of pipes are in that part of the nuclear plant, a complexity often cited in the energy debate over struggling nuclear plants nationwide.

"There is always some level of leakage when you are operating, but it is contained and monitored, and when it rises to a certain level, you may take action to stop it," Holt said.

A nuclear safety watchdog has criticized Dominion for not issuing a public notice about the leak, but both the company and the U.S. Nuclear Regulatory Commission say the amount was so small it did not require notice.

The V.C. Summer Nuclear plant is about 25 miles northwest of Columbia in Fairfield County. It was licensed in the early 1980s. At one point, Dominion's predecessor, SCE&G, partnered with state owned Santee Cooper to build two more reactors there, even as new reactors in Georgia were taking shape. But the companies walked away from the project in 2017, citing high costs and troubles with its chief contractor, Westinghouse, even as closures such as Three Mile Island's shutdown continued to influence policy.

Ontario Clean Electricity Regulations accelerate renewable energy adoption, drive emissions reduction, and modernize the smart grid with energy storage, efficiency targets, and reliability upgrades to support decarbonization and a stable power system for Ontario.

Key Points

Standards to cut emissions, grow renewables, improve efficiency, and modernize the grid with storage and smart systems.

✅ Phases down fossil generation and invests in storage.

✅ Sets utility efficiency targets to curb demand growth.

✅ Upgrades to smart grid for reliability and resiliency.

Ontario has taken a significant step forward in its energy transition with the introduction of new clean electricity regulations. These regulations, complementing federal Clean Electricity Regulations, aim to reduce carbon emissions, promote sustainable energy sources, and ensure a cleaner, more reliable electricity grid for future generations. This article explores the motivations behind these regulations, the strategies being implemented, and the expected impacts on Ontario’s energy landscape.

The Need for Clean Electricity

Ontario, like many regions around the world, is grappling with the effects of climate change, including more frequent and severe weather events. In response, the province has set ambitious targets to reduce greenhouse gas emissions and increase the use of renewable energy sources, reflecting trends seen in Alberta’s path to clean electricity across Canada. The electricity sector plays a central role in this transition, as it is responsible for a significant portion of the province’s carbon footprint.

For years, Ontario has been moving away from coal as a source of electricity generation, and now, with the introduction of these new regulations, the province is taking a step further in decarbonizing its grid, including its largest competitive energy procurement to date. By setting clear goals and standards for clean electricity, the province hopes to meet its environmental targets while ensuring a stable and affordable energy supply for all Ontarians.

Key Aspects of the New Regulations

The regulations focus on encouraging the use of renewable energy sources such as wind, solar, hydroelectric, and geothermal power. One of the key elements of the plan is the gradual phase-out of fossil fuel-based energy sources. This shift is expected to be accompanied by greater investments in energy storage solutions, including grid batteries, to address the intermittency issues often associated with renewable energy sources.

Ontario’s new regulations also emphasize the importance of energy efficiency in reducing overall demand. As part of this initiative, utilities and energy providers will be required to meet strict energy-saving targets and participate in new electricity auctions designed to reduce costs, ensuring that both consumers and businesses are incentivized to use energy more efficiently.

In addition, the regulations promote technological innovation in the electricity sector. By supporting the development of smart grids, energy storage technologies, and advanced power management systems, Ontario is positioning itself to become a leader in the global energy transition.

Impact on the Economy and Jobs

One of the anticipated benefits of the clean electricity regulations is their positive impact on Ontario’s economy. As the province invests in renewable energy infrastructure and clean technologies, new job opportunities are expected to arise in industries such as manufacturing, construction, and research and development. These regulations also encourage innovation in energy services, which could lead to the growth of new companies and industries, while easing pressures on industrial ratepayers through complementary measures.

Furthermore, the transition to cleaner energy is expected to reduce the long-term costs associated with climate change. By investing in sustainable energy solutions now, Ontario will help mitigate the financial burdens of environmental damage and extreme weather events in the future.

Challenges and Concerns

While the new regulations have been widely praised for their environmental benefits, they are not without their challenges. One of the primary concerns is the potential cost to consumers, and some Ontario hydro policy critique has called for revisiting legacy pricing approaches to improve affordability. While renewable energy sources have become more affordable over the years, transitioning from fossil fuels could still result in higher electricity prices in the short term. Additionally, the implementation of new technologies, such as smart grids and energy storage, will require substantial upfront investment.

Moreover, the intermittency of renewable energy generation poses a challenge to grid stability. Ontario’s electricity grid must be able to adapt to fluctuations in energy supply as more variable renewable sources come online. This challenge will require significant upgrades to the grid infrastructure and the integration of storage solutions to ensure reliable energy delivery.

The Road Ahead

Ontario’s clean electricity regulations represent an important step in the province’s commitment to combating climate change and transitioning to a sustainable, low-carbon economy. While there are challenges to overcome, the benefits of cleaner air, reduced emissions, and a more resilient energy system will be felt for generations to come. As the province continues to innovate and lead in the energy sector, Ontario is positioning itself to thrive in the green economy of the future.

Hydro One CEO Pay Cap sets executive compensation at $1.5 million under Ontario's provincial directive, linking incentives to transmission and distribution cost reductions, governance improvements, and board pay limits at the electricity utility.

Key Points

The Hydro One CEO Pay Cap limits pay to $1.5M, linking incentives to cost reductions and defined targets.

✅ Base salary set at $500,000 per year.

✅ Incentives capped at $1,000,000, tied to cost cuts.

✅ Board pay capped: chair $120,000; members $80,000.

Hydro One has agreed to cap the annual compensation of its chief executive at $1.5 million, the provincial utility said Friday, acquiescing to the demands of the Progressive Conservative government.

The CEO's base salary will be set at $500,000 per year, while short-term and long-term incentives are limited to $1 million. Performance targets under the pay plan will include the CEO's contributions to reductions in transmission and distribution costs, even as Hydro One has pursued a bill redesign to clarify charges for customers.

The framework represents a notable political victory for Premier Doug Ford, who vowed to fire Hydro One's CEO and board during the campaign and promised to reduce the annual earnings of Hydro One's board members.

In February, the province issued a directive to the board, ordering it to pay the utility's CEO no more than the $1.5 million figure it has now agreed to, as part of a broader push to lower electricity rates across Ontario.

Hydro One and the government had been at loggerheads over executive compensation, with the company refusing repeated requests to slash the CEO pay below $2,775,000. The board argued it would have difficulty recruiting suitable leaders for anything less, even as customers contend with a recovery rate that could raise hydro bills.

Further, the company agreed to pay the board chair no more than $120,000 annually and board members no more than $80,000 — figures Energy Minister Greg Rickford had outlined in his directive last month, amid calls for cleaning up Ontario's hydro mess from policy commentators.

"Hydro One's compliance with this directive allows us to move forward as a province. It sets the company on the right course for the future, proving that it can operate as a top-class electricity utility while reining in executive compensation and increasing public transparency," Rickford said in a statement issued Friday morning.

U.S. Transmission Grid Modernization underscores FERC policy certainty, high-voltage infrastructure upgrades, renewables integration, electrification, and grid resilience to cut congestion and enable distributed energy resources, safeguarding against extreme weather, cyber threats, and market volatility.

Key Points

A plan to expand, upgrade, and secure high-voltage networks for renewables integration, electrification, reliability.

✅ Replace aging lines to cut congestion and customer costs

✅ Integrate renewables and distributed energy resources at scale

✅ Enhance resilience to weather, cyber, and physical threats

Today, in a high-visibility hearing on U.S. energy delivery infrastructure before the United States Senate Committee on Energy and Natural Resources, WIRES Executive Director and Former FERC Chairman Jim Hoecker addressed the challenges and opportunities that confront the modern high-voltage grid as the industry strives to upgrade and expand it to meet the demands of consumers and the economy.

In prepared testimony and responses to Senators' questions, Hoecker urged the Committee to support industry efforts to expand and upgrade the transmission network and to help regulators, especially the Federal Energy Regulatory Commission (FERC action on aggregated DERs), promote certainty and predictability in energy policy and regulation. 

His testimony stressed these points:

Significant transmission investment is needed now to replace aging infrastructure like the aging grid risks to clean energy, reduce congestion costs, and deliver widespread benefits to customers.

Increasingly, the role of the transmission grid is to integrate new distributed resources and renewable energy into the electric system and make them available to the market.

The changing electric generation mix, including needed nuclear innovation, and the coming electrification of transportation, heating, and other segments of the American economy in the next quarter century will depend on a strong and adaptable electric system. A robust transmission grid will be the linchpin that will enable us to meet those demands.

"Transmission is the common element that will support all future electricity needs and provide a hedge against uncertainties and potential costly outcomes. The time is now to be proactive in encouraging additional investments in our nation's most crucial infrastructure: the electric transmission system," Hoecker said. 

Hoecker's testimony also emphasized that transmission investment will contribute to the overall resilience of the electric system by bringing multiple resources and technologies to bear on threats to the power system, including extreme weather and proposals like a wildfire-resilient grid bill, cyber or physical attacks, or other events.

"Transmission gives us the optionality to adapt to whatever the future holds, and a modern and resilient transmission system, informed by Texas reliability improvements, will be the most valuable energy asset we have," says Nina Plaushin, president of WIRES and vice president of federal affairs, regulatory and communications for ITC Holdings Corp. 

Hoecker closed his testimony by emphasizing that the "electrification" scenario that is being discussed across multiple industries demands action now in order to ensure policy and regulatory certainty that will support needed transmission investment. More studies need to be conducted to better understand and define how this delivery network must be configured and planned in anticipation of this potential transformation in how we use electrical energy.

Global Renewable LCOE Trends reveal offshore wind costs down 32%, with 10MW turbines, lower CAPEX and OPEX, and parity for solar PV and onshore wind in Europe, China, and California, per BloombergNEF analysis.

Key Points

Benchmarks showing falling LCOE for offshore wind, onshore wind, and solar PV, driven by larger turbines and lower CAPEX

✅ Offshore wind LCOE $78/MWh; $53-64/MWh in DK/NL excl. transmission

✅ Onshore wind $47/MWh; solar PV $51/MWh, best $26-36/MWh

✅ Cost drivers: 10MW turbines, lower CAPEX/OPEX, weak China demand

World offshore wind costs have fallen 32% from just a year ago and 12% compared with the first half of 2019, according to a BNEF long-term outlook from BloombergNEF.

In its latest Levelized Cost of Electricity (LCOE) Update, BloombergNEF said its current global benchmark LCOE estimate for offshore wind is $78 a megawatt-hour.

“New offshore wind projects throughout Europe, including the UK's build-out, now deploy turbines with power ratings up to 10MW, unlocking CAPEX and OPEX savings,” BloombergNEF said.

In Denmark and the Netherlands, it expects the most recent projects financed to achieve $53-64/MWh excluding transmission.

New solar and onshore wind projects have reached parity with average wholesale power prices in California and parts of Europe, while in China levelised costs are below the benchmark average regulated coal price, according to BloombergNEF.

The company's global benchmark levelized cost figures for onshore wind and PV projects financed in the last six months are at $47 and $51 a megawatt-hours, underscoring that renewables are now the cheapest new electricity option in many regions, down 6% and 11% respectively compared with the first half of 2019.

BloombergNEF said for wind this is mainly down to a fall in the price of turbines – 7% lower on average globally compared with the end of 2018.

In China, the world’s largest solar market, the CAPEX of utility-scale PV plants has dropped 11% in the last six months, reaching $0.57m per MW.

“Weak demand for new plants in China has left developers and engineering, procurement and construction firms eager for business, and this has put pressure on CAPEX,” BloombergNEF said.

It added that estimates of the cheapest PV projects financed recently – in India, Chile and Australia – will be able to achieve an LCOE of $27-36/MWh, assuming competitive returns for their equity investors.

Best-in-class onshore wind farms in Brazil, India, Mexico and Texas can reach levelized costs as low as $26-31/MWh already, the research said.

Programs such as the World Bank wind program are helping developing countries accelerate wind deployment as costs continue to drop.

BloombergNEF associate in the energy economics team Tifenn Brandily said: “This is a three- stage process. In phase one, new solar and wind get cheaper than new gas and coal plants on a cost-of- energy basis.

“In phase two, renewables reach parity with power prices. In phase three, they become even cheaper than running existing thermal plants.

“Our analysis shows that phase one has now been reached for two-thirds of the global population.

“Phase two started with California, China and parts of Europe. We expect phase three to be reached on a global scale by 2030.

“As this all plays out, thermal power plants will increasingly be relegated to a balancing role, looking for opportunities to generate when the sun doesn’t shine or the wind doesn’t blow.”

AIDAsol shore power Rostock-Warnemfcnde delivers cold ironing for cruise ships, up to 20 MVA at berths P7 and P8, cutting port emissions during berthing and advancing AIDA's green cruising strategy across European ports.

Key Points

Rostock-Warnemfcnde shore power supplies two cruise ships up to 20 MVA, enabling cold ironing and cutting emissions.

✅ Up to 20 MVA; powers two cruise ships at berths P7 and P8

✅ Enables cold ironing for AIDA fleet to reduce berth emissions

✅ Part of AIDA green cruising with fuel cells and batteries

In a ceremony held in Rostock-Warnemünde yesterday during Germany’s 12th National Maritime Conference, the 2,174-passenger cruise ship AIDAsol inaugurated Europe’s largest shore power plants for ships.

The power plant has been established under a joint agreement between AIDA Cruises, a unit of Carnival Corporation & plc (NYSE/LSE: CCL; NYSE: CUK), the state government of Mecklenburg-Western Pomerania, the city of Rostock and the Port of Rostock.

“With our green cruising strategy, we have been investing in a sustainable cruise market for many years,” said AIDA Cruises President Felix Eichhorn. “The shore power plant in Rostock-Warnemünde is another important step — after the facility in Hamburg — on our way to an emission-neutral cruise that we want to achieve with our fleet. I would like to thank the state government of Mecklenburg-Western Pomerania and all partners involved for the good and trusting cooperation. Together, we are sending out an important signal, not just in Germany, but throughout Europe.”

CAN POWER TWO CRUISE SHIPS AT A TIME
The shore power plant, which was completed in summer 2020, is currently the largest in Europe and aligns with port electrification efforts such as the all-electric berth at London Gateway in the UK. With an output of up to 20 megavolt amperes (MVA), two cruise ships can be supplied with electricity at the same time at berths P7 and P8 in Warnemünde.

In regular passenger operation AIDAsol needs up to 4.5 megawatts per hour (MWh) of electricity.

The use of shore power to supply ships with energy is a decisive step in AIDA Cruises’ plans to reduce local emissions to zero during berthing, complementing recent progress with electric ships on the B.C. coast, as a cruise ship typically stays in port around 40% of its operating time.

As early as 2004, when the order for the construction of AIDAdiva was placed, and for all other ships put into service in subsequent years, the company has considered the use of shore power as an option for environmentally friendly ship operation.

Since 2017, AIDA Cruises has been using Europe’s first shore power plant in Hamburg-Altona, where AIDAsol is in regular operation, while operators like BC Ferries add hybrid ferries to expand low-emission service in Canada. Currently, 10 ships in the AIDA fleet can either use shore power where available or are technically prepared for it.

The aim is to convert all ships built from 2000 onwards, supporting future solutions like offshore charging with wind power.

With AIDA Cruises starting a cruise season from Kiel, Germany, on May 22, AIDAsol will also be the first cruise ship to complete the final tests on a newly built shore power plant there, as innovations such as Berlin’s electric flying ferry highlight the broader shift toward electrified waterways. Construction of that plant is the result of a joint initiative by the state government of Schleswig-Holstein, the city and the port of Kiel and AIDA Cruises. AIDAsol is scheduled to arrive in Kiel on the afternoon of May 13.

As part of its green cruising strategy, AIDA Cruises has been investing in a sustainable cruise operation for many years, paralleling urban shifts toward zero-emission bus fleets in Berlin. Other steps on the path to the zero emission ship of the future are already in preparation. This year, AIDAnova will receive the first fuel cell to be used on an ocean-going cruise ship. In 2022, the largest battery storage system to date in cruise shipping will go into operation on board an AIDA ship, similar to advances in battery-electric ferries in the U.S. In addition, the company is already addressing the question of how renewable fuels can be used on board cruise ships in the future.
