A malfunction caused a shutdown of a nuclear power reactor at one of South Korea's atomic power plants, authorities said.

Operators at the Younggwang Nuclear Power Plant in South Cholla Province said operations of Unit No. 1 were suspended after a malfunction was detected.

"There was no radiation leakage, and once experts determine the exact cause of the malfunction, operations will begin again," said a spokesman for the plant, located 322 kilometres south of Seoul. Minor malfunctions that could lead to a shutdown are not reported to the International Atomic Energy Agency.

The generator is one of six units in the power plant. It went into commercial operation in August 1986 and has generates 950 megawatt of electricity.

In addition to the Younggwang plant, South Korea operates 20 nuclear reactors throughout the country that fuel 40 per cent of the country's electricity needs.

Federal Government announces funding for Manitoba-Saskatchewan power line

Birtle Transmission Line connects Manitoba Hydro to SaskPower, enabling 215 MW of clean hydroelectricity, improving grid reliability, supporting affordable rates, and advancing Green Infrastructure goals under the Investing in Canada Plan across Manitoba and Saskatchewan.

 

Key Points

A 46 km line moving up to 215 MW from Manitoba Hydro to SaskPower, improving reliability and supplying cleaner power.

✅ Enables interprovincial grid tie between Manitoba and Saskatchewan

✅ Delivers up to 215 MW of renewable hydroelectricity

✅ Supports affordable rates and lower GHG emissions

 

The federal government announced funding for the Birtle Transmission Line Monday morning.

The project will help Manitoba Hydro build a transmission line from Birtle South Station in the Municipality of Prairie View to the Manitoba–Saskatchewan border 46 kilometres northwest. Once completed, the new line will allow up to 215 megawatts of hydroelectricity to flow from the Manitoba Hydro power grid to the SaskPower power grid, similar to the Great Northern Transmission Line connecting Manitoba and Minnesota today.

The government said the transmission line would create a more stable energy supply, keep energy rates affordable and help Saskatchewan's efforts to reduce cumulative greenhouse-gas emissions in that province.

"The Government of Canada is proud to be working with Manitoba to support projects that create jobs and improve people's lives across the province. The Birtle Transmission Line will provide the region with reliable and greener energy, as seen with Canadian hydropower to New York projects, that will help protect our environment while laying the groundwork for clean economic growth," said Jim Carr, member of Parliament for Winnipeg South Centre, on behalf of Catherine McKenna, minister of infrastructure and communities.

The Government of Canada is investing more than $18.7 million, and the government of Manitoba is contributing more than $42 million in this project through the Green Infrastructure Stream of the Investing in Canada Plan, which also supports Atlantic grid improvements nationwide.

"The Province of Manitoba has one of the cleanest electricity grids in Canada and the world with over 99 per cent of our electricity generated from clean, renewable sources, rooted in Manitoba's hydro history," said Central Services Minister Reg Helwer. "The Made-in-Manitoba Climate and Green Plan is good not only for Manitoba but for Canada and globally."

Jay Grewal, president, and CEO of Manitoba Hydro said the funding is a great example of co-operation between the provincial and federal governments, including investments in smart grid technology that modernize local networks.

"We are very pleased that Manitoba Hydro's Birtle Transmission Project is among the first projects to receive funding under the Canada Infrastructure Program, and we would like to thank both levels of governments for recognizing the importance of the project as we strengthen ties with our neighbours in Saskatchewan, as U.S.-Canada transmission approvals advance elsewhere," said Grewal.

A spokesperson for Manitoba Hydro said it’s too early to say how many jobs will be created during construction, as final contracts have not yet been awarded.

Ireland and France will connect their electricity grids - here's how

Celtic Interconnector, a subsea electricity link between Ireland and France, connects EU grids via a high-voltage submarine cable, boosting security of supply, renewable integration, and cross-border trade with 700 MW capacity by 2026.

 

Key Points

A 700 MW subsea link between Ireland and France, boosting security, enabling trade, and supporting renewables.

✅ Approx. 600 km subsea cable from East Cork to Brittany

✅ 700 MW capacity; powers about 450,000 homes

✅ Financed by EIB, banks, CEF; Siemens Energy and Nexans

 

France and Ireland signed contracts on Friday to advance the Celtic Interconnector, a subsea electricity link to allow the exchange of electricity between the two EU countries. It will be the first interconnector between continental Europe and Ireland, as similar UK interconnector plans move forward in parallel. 

Representatives for Ireland’s electricity grid operator EirGrid and France’s grid operator RTE signed financial and technical agreements for the high-voltage submarine cable, mirroring developments like Maine’s approved transmission line in North America for cross-border power. The countries’ respective energy ministers witnessed the signing.

European commissioner for energy Kadri Simson said:

In the current energy market situation, marked by electricity price volatility, and the need to move away from imports of Russian fossil fuels, European energy infrastructure has become more important than ever.

The Celtic Interconnector is of paramount importance as it will end Ireland’s isolation from the Union’s power system, with parallels to Cyprus joining the electricity highway in the region, and ensure a reliable high-capacity link improving the security of electricity supply and supporting the development of renewables in both Ireland and France.

EirGrid and RTE signed €800 million ($827 million) worth of financing agreements with Barclays, BNP Paribas, Danske Bank, and the European Investment Bank, similar to the Lake Erie Connector investment that blends public and private capital.

In 2019, the project was awarded a Connecting Europe Facility (CEF) grant worth €530.7 million to support construction works and align with a broader push for electrification in Europe under climate strategies. The CEF program also provided €8.3 million for the Celtic Interconnector’s feasibility study and initial design and pre-consultation.

Siemens Energy will build converter stations in both countries, and Paris-based global cable company Nexans will design and install a 575-km-long cable for the project.

The cable will run between East Cork, on Ireland’s southern coast, and northwestern France’s Brittany coast and will connect into substations at Knockraha in Ireland and La Martyre in France.

The Celtic Interconnector, which is expected to be operational by 2026, will be approximately 600 km (373 miles) long and have a capacity of 700 MW, similar to cross-border initiatives such as Quebec-to-New York power exports expected in 2025, which is enough to power 450,000 households.

Ontario to seek new wind, solar power to help ease coming electricity supply crunch

Ontario Clean Grid Plan outlines emissions-free electricity growth, renewable energy procurement, nuclear expansion at Bruce and Darlington, reduced natural gas, grid reliability, and net-zero alignment to meet IESO demand forecasts and EV manufacturing loads.

 

Key Points

A plan to expand emissions-free power via renewables and nuclear, cut natural gas use, and meet growing demand.

✅ Targets renewables, hydro, and nuclear capacity growth

✅ Aims to reduce reliance on gas for grid reliability

✅ Aligns with IESO demand forecasts and EV manufacturing loads

 

Ontario is working toward filling all of the province’s quickly growing electricity needs with emissions-free sources, including a plan to secure new renewable generation and clean power options, but isn’t quite ready to commit to a moratorium on natural gas.

Energy Minister Todd Smith announced Monday a plan to address growing energy needs for 2030 to 2050 — the Independent Electricity System Operator projects Ontario’s electricity demand could double by mid-century — and next steps involve looking for new wind, solar and hydroelectric power.

“While we may not need to start building today, government and those in the energy sector need to start planning immediately, so we have new clean, zero-emissions projects ready to go when we need them,” Smith said in Windsor, Ont.

The strategy also includes two nuclear projects announced last week — a new large-scale nuclear plant at Bruce Power on the shore of Lake Huron and three new small modular reactors at the site of the Darlington nuclear plant east of Toronto.

Those projects, enough to power six million homes, will help Ontario end its reliance on natural gas to generate electricity, said Smith, but committing to a natural gas moratorium in 2027 and eliminating natural gas by 2050 is contingent on the federal government helping to speed up the new nuclear facilities.

“Today’s report, the Powering Ontario’s Growth plan, commits us to working towards a 100 per cent clean grid,” Smith said in an interview.

“Hopefully the federal government can get on board with our intentions to build this clean generation as quickly as possible … That will put us in a much better position to use our natural gas facilities less in the future, if we can get those new projects online.”

The IESO has said that natural gas is required to ensure supply and stability in the short to medium term, as Ontario works on balancing demand and emissions across the grid, but that it will also increase greenhouse gas emissions from the electricity sector.

The province is expected to face increased demand for electricity from expanded electric vehicle use and manufacturing in the coming years, even as a $400-billion cost estimate for greening the grid is debated.

Keith Brooks, programs director for Environmental Defence, said the provincial plan could have been much more robust, containing firm timelines and commitments.

“This plan does not commit to getting emissions out of the system,” he said.

“It doesn’t commit to net zero, doesn’t set a timeline for a net zero goal or have any projection around emissions from Ontario’s electricity sector going forward. In fact, it’s not really a plan. It doesn’t set out any real goals and it doesn’t it doesn’t project what Ontario’s supply mix might look like.”

The Canadian Climate Institute applauded the plan’s focus on reducing reliance on gas-fired generation and emphasizing non-emitting generation, but also said there are still some question marks.

“The plan is silent on whether the province intends to construct new gas-fired generation facilities,” even as new gas plant expansions are proposed, senior research director Jason Dion wrote in a statement.

“The province should avoid building new gas plants since cost-effective alternatives are available, and such facilities are likely to end up as stranded assets. The province’s timeline for reaching net zero generation is also unclear. Canada and other G7 countries have set a target for 2035, something Ontario will need to address if it wants to remain competitive.”

Aging U.S. power grid threatens progress on renewables, EVs

U.S. Grid Modernization is critical for renewable energy integration, EV adoption, climate resilience, and reliability, requiring transmission upgrades, inter-regional links, hardened substations, and smart grid investments to handle extreme weather and decarbonization targets.

 

Key Points

U.S. Grid Modernization upgrades power networks to improve reliability, integrate renewables, and support EV demand.

✅ $2T+ investment needed for transmission upgrades

✅ Extreme weather doubling outages since 2017

✅ Regulatory fragmentation slows inter-regional lines

 

After decades of struggle, the U.S. clean-energy business is booming, with soaring electric-car sales and fast growth in wind and solar power. That’s raising hopes for the fight against climate change.

All this progress, however, could be derailed, as the green revolution stalls without a massive overhaul of America’s antiquated electric infrastructure – a task some industry experts say requires more than $2 trillion. The current network of transmission wires, substations and transformers is decaying with age and underinvestment, a condition highlighted by catastrophic failures during increasingly frequent and severe weather events.

Power outages over the last six years have more than doubled in number compared to the previous six years, according to a Reuters examination of federal data. In the past two years, power systems have collapsed in Gulf Coast hurricanes, West Coast wildfires, Midwest heat waves and a Texas deep freeze and recurring Texas grid crisis risks, causing long and sometimes deadly outages.

Compounding the problem, the seven regional grid operators in the United States are underestimating the growing threat of severe weather caused by climate change, Reuters found in a review of more than 10,000 pages of regulatory documents and operators’ public disclosures. Their risk models, used to guide transmission-network investments, consider historical weather patterns extending as far back as the 1970s. None account for scientific research documenting today’s more extreme weather and how it can disrupt grid generation, transmission and fuel supplies simultaneously.

The decrepit power infrastructure of the world’s largest economy is among the biggest obstacles to expanding clean energy and combating climate change on the ambitious schedule laid out by U.S. President Joe Biden. His administration promises to eliminate or offset carbon emissions from the power sector by 2035 and from the entire U.S. economy by 2050. Such rapid clean-energy growth would pressure the nation’s grid in two ways: Widespread EV adoption will spark a huge surge in power demand; and increasing dependence on renewable power creates reliability problems on days with less sun or wind, as seen in Texas, where experts have outlined reliability improvements that address these challenges.

The U.S. transmission network has seen outages double in recent years amid more frequent and severe weather events, driven by climate change and a utility supply-chain crunch that slows critical repairs. The system needs a massive upgrade to handle expected growth in clean energy and electric cars. 

“Competition from renewables is being strangled without adequate and necessary upgrades to the transmission network,” said Simon Mahan, executive director of the Southern Renewable Energy Association, which represents solar and wind companies.

The federal government, however, lacks the authority to push through the massive grid expansion and modernization needed to withstand wilder weather and accommodate EVs and renewable power. Under the current regulatory regime, and amid contentious electricity pricing proposals in recent years, the needed infrastructure investments are instead controlled by a Byzantine web of local, state and regional regulators who have strong political incentives to hold down spending, according to Reuters interviews with grid operators, federal and state regulators, and executives from utilities and construction firms.

“Competition from renewables is being strangled without adequate and necessary upgrades to the transmission network.”

Paying for major grid upgrades would require these regulators to sign off on rate increases likely to spark strong opposition from consumers and local and state politicians, who are keen to keep utility bills low. In addition, utility companies often fight investments in transmission-network improvements because they can result in new connections to other regional grids that could allow rival companies to compete on their turf, even as coal and nuclear disruptions raise brownout risks in some regions. With the advance of green energy, those inter-regional connections will become ever more essential to move power from far-flung solar and wind installations to population centers.

The power-sharing among states and regions with often conflicting interests makes it extremely challenging to coordinate any national strategy to modernize the grid, said Alison Silverstein, an independent industry consultant and former senior adviser to the U.S. Federal Energy Regulatory Commission (FERC).

“The politics are a freakin’ nightmare,” she said.

The FERC declined to comment for this story. FERC Commissioner Mark Christie, a Republican, acknowledged the limitations of the agency’s power over the U.S. grid in an April 21 agency meeting involving transmission planning and costs.

“We can’t force states to do anything,” Christie said.

The White House and Energy Department did not comment in response to detailed questions from Reuters on the Biden administration’s plans to tackle U.S. grid problems and their impact on green-energy expansion.

The administration said in an April news release that it plans to offer $2.5 billion in grants for grid-modernization projects as part of Biden’s $1 trillion infrastructure package, complementing a proposed clean electricity standard to accelerate decarbonization over the next decade. A modernized grid, the release said, is the “linchpin” of Biden’s clean-energy agenda.

Minister approves 30-megawatt wind farm expansion in Eastern Kings

Eastern Kings Wind Farm Expansion advances P.E.I. renewable energy with seven new wind turbines, environmental assessment, wildlife monitoring of birds and bats, and community consultation to double output to 30 MW for domestic consumption.

 

Key Points

A P.E.I. project adding seven turbines for 30 MW, under 17 conditions, with wildlife monitoring and community oversight.

✅ Seven new turbines, larger than existing units

✅ 17 conditions, monthly compliance reporting

✅ Two-year wildlife study for birds and bats

 

A proposal to expand an existing wind farm in eastern P.E.I. has been given the go-ahead, according to P.E.I.’s Department of Environment, Water and Climate Change, as related grid work like a new transmission line progresses in the region.

Minister Natalie Jameson approved the P.E.I. Energy Corporation’s Eastern Kings Wind Farm expansion project, the province announced in a release Wednesday afternoon, as Atlantic Canada advances other renewable initiatives like tidal power to diversify supply.

The project will be subject to 17 conditions, which were drawn from a review of the 80 responses the province received from the public on the proposed Eastern Kings Wind Farm expansion.

The corporation must provide a summary on the status of each condition to the department on a monthly basis.

“This decision balances the needs of people, communities, wellness and the environment,” Jameson said in the release.

“It allows this renewable energy project to proceed and reduce greenhouse [gas] emissions that cause climate change while mitigating the project’s impact to the Island’s ecosystem.”

The P.E.I. Energy Corporation wants to double the output of its Eastern Kings Wind Farm with the installation of seven wind turbines between the communities of Elmira and East Point to develop 30 megawatts of wind power for domestic consumption, according to the minister’s impact assessment, aligning with regional moves to expand wind and solar projects across Atlantic Canada.

The new turbines are expected to be larger than the existing 10 at the site, even as regional utilities study major grid changes to integrate more renewables.

Project must comply with conditions

In February, the province said it would identify any specific questions or concerns it felt needed to be addressed in the submissions, according to Greg Wilson, manager of environmental land management for the province, while some advocate for independent electricity planning to guide such decisions.

Public feedback closed in January, after an earlier extension to wait for a supplemental report on birds and bats.

The corporation needs to comply with all conditions – such as monitoring environmental impact, setting up an environmental management plan and creating a committee to address concerns – listed in the release on Wednesday, amid calls from environmental advocates to reduce biomass use in electricity generation.

A condition in the release suggests representatives from L’nuey, the Souris and Area Wildlife Branch, the Rural Municipality of Eastern Kings and local residents to make up the committee.

The corporation will also need to conduct a study over two years after construction to look at the impact on bats and birds, and implement a protocol to report deaths of birds to federal and provincial authorities.

According to Canada Energy Regulator, roughly 98 per cent of power generated on P.E.I. comes from wind farms. It also said there were 203 megawatts installed on P.E.I. as of 2018, and the majority of energy consumed on the Island comes from New Brunswick from a mix of nuclear, fossil fuels and hydroelectricity, while in Nova Scotia, the utility has increased biomass generation as part of its supply mix.
