To meet electric power demands, Japan's Ministry of Land, Infrastructure and Transport MLIT has announced that it will reopen five closed hydropower plants.

One of the stations belongs to East Japan Railway Company JR East and is located along the Shinano River in Niigata prefecture. The remaining four, Shiobara, Shinanogawa, Kiyotsugawa-Yuzawa and Uonogawa-Ishiuchi, belong to Tokyo Electric Power Company Incorporated TEPCO.

The Shiobara plant was shut down for unlicensed operation in 2007. However after the earthquake, all accrued punishment was lifted, and TEPCO was given special permission by MLIT to bring the power station back into operation. TEPCO and JR East were given permission to reduce river capacity in order to generate power for electrical demand.

The five hydropower stations are expected to bring 360 megawatts of power online and will be able to provide electricity for at least 120,000 homes throughout TEPCO's service area.

TEPCO announced that it would be unable to sufficiently provide electricity to its service area due to a compromised electrical infrastructure and the loss of several key power stations, including Fukushima Daiichi nuclear power station and Fukushima Daini nuclear power station. TEPCO's service area includes Yamanashi and Shizuoka prefectures, as well as the Kanto region of Japan, which is comprised of Tokyo, Chiba, Kanagawa, Gunma, Tochigi, Saitama and Ibaraki prefectures.

As a result of insufficient electrical capacity, the company broke its service area into five groups that are currently undergoing scheduled power outages in specified time blocks. TEPCO typically provides for a daily 40-gigawatt GW power demand from these areas, but announced that it would only be able to provide approximately 20 GW and called on residents, businesses, and industries alike to cooperate in conserving power to aid in power outages.

U.S. Ends Support for Ukraine’s Energy Grid Restoration

US Termination of Ukraine Energy Grid Support signals a policy shift: USAID halts aid for grid restoration amid Russia attacks, impacting energy security, infrastructure resilience, winter readiness, and negotiations leverage with Moscow and allies.

 

Key Points

A US policy reversal ending USAID support for Ukraine's grid, impacting energy security, resilience, and leverage.

✅ USAID halt reduces funds for grid restoration and winter prep

✅ Policy shift may weaken Kyiv's leverage in talks with Russia

✅ Ukraine seeks EU, IFIs, private capital for energy resilience

 

The U.S. government has recently decided to terminate its support for Ukraine's energy grid restoration, a critical initiative managed by the U.S. Agency for International Development (USAID). This decision, reported by NBC News, comes at a time when Ukraine is grappling with significant challenges to its energy infrastructure due to ongoing Russian attacks. The termination of support was reportedly finalized before Ukrainian President Volodymyr Zelensky's scheduled visit to Washington, marking a significant shift in U.S. policy and raising concerns about the broader implications for Ukraine's energy resilience and its negotiations with Russia.

The Critical Role of U.S. Support

Since Russia's invasion of Ukraine, the country’s energy infrastructure has been one of the primary targets of military strikes. Russia has launched numerous attacks on Ukraine's power generation facilities, substations, and power lines, causing power outages across multiple regions. These attacks have led to significant material losses, with damage reaching billions of dollars. As part of its commitment to Ukraine, the U.S. government, through USAID, had been instrumental in funding restoration efforts aimed at rebuilding and reinforcing Ukraine’s energy grid.

USAID's support was crucial in helping Ukraine withstand the damage inflicted by Russian missile strikes. This aid was not just about restoring basic services but also about fortifying the energy grid to ensure that Ukraine could continue functioning amidst the war and keep the lights on this winter as temperatures drop. The U.S. contribution to Ukraine's energy sector, alongside international support, helped reduce the immediate vulnerabilities faced by Ukraine's civilians and industries.

The Abrupt Change in U.S. Policy

The decision to cut support for energy grid restoration is seen as a sharp reversal in U.S. policy, particularly as the Biden administration has previously shown strong backing for Ukraine in the aftermath of the invasion. This shift in policy was reportedly made by the U.S. State Department, which directed USAID to halt its involvement in the energy sector.

According to NBC News, USAID officials expressed concern about the timing of this decision. One official noted that terminating support for Ukraine’s energy grid restoration would severely undermine the U.S. government's ability to negotiate on issues like ceasefires and peace talks with Russia. The official argued that such a move would signal to Russia that the U.S. is backing away from its long-term investments in Ukraine, potentially weakening Ukraine's position in the ongoing war.

The abrupt end to this support is also seen as a blow to the morale of Ukraine’s government and people. Ukraine had been heavily reliant on the U.S. for resources to repair its critical infrastructure, and the decision to cut this support without warning has created uncertainty about the future of such recovery efforts.

Ukraine’s Response and Search for Alternatives

In response to the termination of U.S. support, Ukrainian officials have been seeking alternative sources of funding to continue the restoration of their energy grid. Deputy Prime Minister Olha Stefanishyna reported that Ukraine has already reached preliminary agreements with other international partners to secure financial support for energy resilience, cyber defense, and recovery programs including new energy solutions for winter blackouts.

These efforts come at a time when Ukraine is working to rebuild its war-torn economy and safeguard critical sectors like energy and infrastructure. The termination of U.S. support for energy restoration projects underscores the growing pressure on Ukraine to diversify its sources of aid and not become overly dependent on any one nation. Ukrainian leaders are in ongoing talks with European governments, international financial institutions, and private investors to ensure that essential programs do not stall due to the lack of funding from the U.S., as energy cooperation grows and Ukraine helps Spain amid blackouts in solidarity.

Implications for Ukraine’s Energy Security

Ukraine's energy security remains a critical issue in the context of the ongoing conflict with Russia. The war has made the country’s energy infrastructure vulnerable to repeated attacks, and the restoration of this infrastructure is essential for ensuring that Ukraine can keep the lights on and recover in the long term. The U.S. has been one of the largest contributors to Ukraine's energy security efforts, and its withdrawal could force Ukraine to look for other partners who may not have the same level of financial or technological resources.

This development also raises questions about the future of U.S. involvement in Ukraine's recovery efforts more broadly. As the war continues and winter looms over the battlefront for frontline communities, the need for reliable and sustained support from international partners will only increase. If the U.S. significantly scales back its aid, Ukraine may face even greater challenges in maintaining its energy infrastructure and achieving long-term recovery.

Moving Forward

The termination of U.S. support for Ukraine’s energy grid restoration serves as a reminder of the complexities involved in international aid and geopolitics during wartime. As Ukraine faces the ongoing realities of the war, it must adapt to a shifting international landscape where traditional allies may not always be reliable sources of support. Ukraine’s leadership will need to be strategic in its search for alternative sources of aid, while also focusing on strengthening its energy grid, managing electricity reserves to stabilize supply, and reducing its vulnerabilities to Russian attacks.

While the end of U.S. support for Ukraine's energy restoration is a significant setback, it also underscores the urgent need for Ukraine to diversify its international partnerships. The future of Ukraine’s energy resilience may depend on how effectively it can navigate these changing dynamics while maintaining the support of the international community in the fight against Russian aggression.

Alberta breaks summer electricity record, still far short of capacity

Alberta Electricity Peak Demand surged to 10,638 MW, as AESO reported record summer load from air conditioning, Stampede visitors, and heatwave conditions, with ample generation capacity, stable grid reliability, and conservation urged during 5-7 p.m.

 

Key Points

It is the record summer power load in Alberta, reaching 10,638 MW, with evening conservation urged by AESO.

✅ Record 10,638 MW at 4 pm; likely to rise this week

✅ Drivers: A/C use, heat, Stampede visitors

✅ AESO reports ample capacity; conserve 5-7 pm

 

Consumer use hit 10,638 MW, blowing past a previous high of 10,520 MW set on July 9, 2015, said the Alberta Electric System Operator (AESO).

“We hit a new summer peak and it’s likely we’ll hit higher peaks as the week progresses,” said AESO spokeswoman Tara De Weerd.

“We continue to have ample supply, and as Alberta's electricity future trends toward more wind, our generators are very confident there aren’t any issues.”

That new peak was set at 4 p.m. but De Weerd said it was likely to be exceeded later in the day.

Heightened air conditioner use is normally a major driver of such peak electricity consumption, said De Weerd.

She also said Calgary’s big annual bash is also likely playing a role.

“It’s the beginning of Stampede, you have an influx of visitors so you’ll have more people using electricity,” she said.

Alberta’s generation capacity is 16,420 MW, said the AESO, with wind power increasingly outpacing coal in the province today.

There are no plans, she said, for any of the province’s electricity generators to shut down any of their plants for maintenance or other purposes in the near future as demand rises.

The summer peak is considerably smaller than that reached in the depths of Alberta’s winter.

Alberta’s winter peak usage was recorded last year and was 11,458 MW.

Though the province’s capacity isn’t being strained by the summer heat, De Weerd still encouraged consumers to go easy during the peak use time of the day, between 5 and 7 p.m.

“We don’t have to be running all of our appliances at once,” she said.

Alberta exports an insignificant amount of electricity to Montana, B.C. and Saskatchewan, where demand recently set a new record.

The weather forecast calls for temperatures to soar above 30C through the weekend.

In northern Canada, Yukon electricity demand recently hit a record high, underscoring how extreme temperatures can strain systems.

Abengoa, Acciona to start work on 110MW Cerro Dominador CSP plant in Chile

Cerro Dominador CSP Plant delivers 110MW concentrated solar power in Chile's Atacama Desert, with 10,600 heliostats, 17.5-hour molten salt storage, and 24/7 dispatchable energy; built by Acciona and Abengoa within a 210MW complex.

 

Key Points

A 110MW CSP solar-thermal plant in Chile with heliostats and 17.5h molten salt storage, delivering 24/7 dispatchable clean power.

✅ 110MW CSP with 17.5h molten salt for 24/7 dispatch

✅ 10,600 heliostats; part of a 210MW hybrid CSP+PV complex

✅ Built by Acciona and Abengoa; first of its kind in LatAm

 

A consortium formed by Spanish groups Abengoa and Acciona, as Spain's renewable sector expands with Enel's 90MW wind build activity, has signed a contract to complete the construction of the 110MW Cerro Dominador concentrated solar power (CSP) plant in Chile.

The consortium received notice to proceed to build the solar-thermal plant, which is part of the 210MW Cerro Dominador solar complex.

Under the contract, Acciona, which has 51% stake in the consortium and recently launched a 280 MW Alberta wind farm, will be responsible for building the plant while Abengoa will act as the technological partner.

Expected to be the first of its kind in Latin America upon completion, the plant is owned by Cerro Dominador, which in turn is owned by funds managed by EIG Global Energy Partners.

The project will add to a Abengoa-built 100MW PV plant, comparable to California solar projects in scope, which was commissioned in February 2018, to form a 210MW combined CSP and PV complex.

Spread across an area of 146 hectares, the project will feature 10,600 heliostats and will have capacity to generate clean and dispatachable energy for 24 hours a day using its 17.5 hours of molten salt storage technology, a field complemented by battery storage advances.

Expected to prevent 640,000 tons of CO2 emission, the plant is located in the commune of María Elena, in the Atacama Desert, in the Antofagasta Region.

“In total, the complex will avoid 870,000 tons of carbon dioxide emissions into the atmosphere every year and, in parallel with Enel's 450 MW U.S. wind operations, will deliver clean energy through 15-year energy purchase agreements with distribution companies, signed in 2014.

“The construction of the solarthermal plant of Cerro Dominador will have an important impact on local development, with the creation of more than 1,000 jobs in the area during its construction peak, and that will be priority for the neighbors of the communes of the region,” Acciona said in a statement.

The Cerro Dominador plant represents Acciona’s fifth solar thermal plant being built outside of Spain. The firm has constructed 10 solarthermal plants with total installed capacity of 624MW.

Acciona has been operating in Chile since 1993. The company, through its Infrastructure division, executed various construction projects for highways, hospitals, hydroelectric plants and infrastructures for the mining sector.

Environmentalist calls for reduction in biomass use to generate electricity

Nova Scotia Biomass Energy faces scrutiny as hydropower from Muskrat Falls via the Maritime Link increases, raising concerns over carbon emissions, biodiversity, ratepayer costs, and efficiency versus district heating in the province's renewable mix.

 

Key Points

Electricity from wood chips and waste wood in Nova Scotia, increasingly questioned as hydropower from the Maritime Link grows.

✅ Hydropower deliveries reduce need for biomass on the grid

✅ Biomass is inefficient, costly, and impacts biodiversity

✅ District heating offers better use of forestry residuals

 

The Ecology Action Centre's senior wilderness coordinator is calling on the Nova Scotia government to reduce the use of biomass to generate electricity now that more hydroelectric power is flowing into the province.

In 2020, the government of the day signed a directive for Nova Scotia Power to increase its use of biomass to generate electricity, including burning more wood chips, waste wood and other residuals from the forest industry. At the time, power from Muskrat Falls hydroelectric project in Labrador was not flowing into the province at high enough levels to reach provincial targets for electricity generated by renewable resources.

In recent months, however, the Maritime Link from Muskrat Falls has delivered Nova Scotia's full share of electricity, and, in some cases, even more, as the province also pursues Bay of Fundy tides projects to diversify supply.

Ray Plourde with the Ecology Action Centre said that should be enough to end the 2020 directive.

Biomass is "bad on a whole lot of levels," said Plourde, including its affects on biodiversity and the release of carbon into the atmosphere, he said. The province's reliance on waste wood as a source of fuel for electricity should be curbed, said Plourde.

"It's highly inefficient," he said. "It's the most expensive electricity on the power grid for ratepayers."

A spokesperson for the provincial Natural Resources and Renewables Department said that although the Maritime Link has "at times" delivered adequate electricity to Nova Scotia, "it hasn't done so consistently," a context that has led some to propose an independent planning body for long-term decisions.

"These delays and high fossil fuel prices mean that biomass remains a small but important component of our renewable energy mix," Patricia Jreiga said in an email, even as the province plans to increase wind and solar projects in the years ahead.

But to Plourde, that explanation doesn't wash.

The Nova Scotia Utility and Review Board recently ruled that Nova Scotia Power could begin recouping costs of the Maritime Link project from ratepayers. As for the rising cost of fossil fuels, Ploude noted that the inefficiency of biomass means there's no deal to be had using it as a fuel source.

"Honestly, that sounds like a lot of obfuscation," he said of the government's position.

No update on district heating plans
At the time of the directive, government officials said the increased use of forestry byproducts at biomass plants in Point Tupper and Brooklyn, N.S., including the nearby Port Hawkesbury Paper mill, would provide a market for businesses struggling to replace the loss of Northern Pulp as a customer. Brooklyn Power has been offline since a windstorm damaged that plant in February, however. Repairs are expected to be complete by the end of the year or early 2023.

Ploude said a better use for waste wood products would be small-scale district heating projects, while others advocate using more electricity for heat in cold regions.

Although the former Liberal government announced six public buildings to serve as pilot sites for district heating in 2020, and a list of 100 other possible buildings that could be converted to wood heat, there have been no updates.

"Currently, we're working with several other departments to complete technical assessments for additional sites and looking at opportunities for district heating, but no decisions have been made yet," provincial spokesperson Steven Stewart said in an email.

N.S. senior suspects smart meter to blame for shocking $666 power bill

Nova Scotia Power smart meter billing raises concerns amid estimated billing, catch-up bills, and COVID-19 meter reading delays, after seniors report doubled electricity usage and higher utility charges despite consistent consumption and on-time payments.

 

Key Points

Smart meter billing uses digital reads, limits estimates, and may trigger catch-up charges after reading suspensions.

✅ COVID-19 reading pause led to estimated bills and later catch-ups

✅ Smart meters reduce reliance on estimated billing errors

✅ Customers can seek payment plans and bill reviews

 

A Nova Scotia senior says she couldn't believe her eyes when she opened her most recent power bill. 

Gloria Chu was billed $666 -- more than double what she normally pays, and similar spikes such as rising electricity bills in Calgary have drawn attention.

As someone who always pays her bi-monthly Nova Scotia Power bill in full and on time, Chu couldn't believe it.

According to her bill, her electricity usage almost tripled during the month of May, compared to last year, and is even more than it was last winter, and with some utilities exploring seasonal power rates customers may see confusing swings.

She insists she and her husband aren't doing anything differently -- but one thing has changed.

"I have had a problem since they put the smart meter in," said Chu, who lives in Upper Gulf Shore, N.S.

Chu got a big bill right after the meter was installed in January, too. That one was more than $530.

She paid it, but couldn't understand why it was so high.

As for this bill, she says she just can't afford it, especially amid a recently approved 14% rate hike in Nova Scotia.

"That's all of my CPP," Chu said. "Actually, it's more than my CPP."

Chu says a neighbor up the road who also has a smart meter had her bill double, too. In nearby Pugwash, she says some residents have seen an increase of about $20-$30.

Nova Scotia Power had put a pause on installing smart meters because of the COVID-19 pandemic, but it has resumed as of June 1, with the goal of upgrading 500,000 meters by 2021, even as in other provinces customers have faced fees for refusing smart meters during similar rollouts.

In this case, the utility says it's not the meter that's the problem, and notes that in New Brunswick some old meters gave away free electricity even as the pandemic forced Nova Scotia Power to suspend meter readings for two months.

"As a result, every one of our customers in Nova Scotia received an estimated bill," said Jennifer parker, Nova Scotia Power's director of customer care.

The utility estimated Chu's bill at $182 -- less than she normally pays -- so her latest bill is considered a catch-up bill after meter readings resumed last month.

Parker admits how estimates are calculated isn't perfect.

"There would be a lot of customers who probably had a more accurate bill because of the way that we estimate, and that's actually one of things that smart meters will get rid of, is that we won't need to do estimated billing," Parker said.

Chu isn't quite convinced.

"It is pretty smart for the power company, but it's not smart for us," she said with a laugh.

Nova Scotia Power has put a hold on her bill and says it will work with Chu on an affordable solution, though the province cannot order the utility to lower rates which limits what can be offered.

She just hopes to never see a big bill like this again, while elsewhere in Newfoundland and Labrador a lump-sum electricity credit is being provided to help customers.

Energy dashboard: how is electricity generated in Great Britain?

Great Britain electricity generation spans renewables and baseload: wind, solar, nuclear, gas, and biomass, supported by National Grid interconnectors, embedded energy estimates, and BMRS data for dynamic imports and exports across Europe.

 

Key Points

A diverse, weather-driven mix of renewables, gas, nuclear, and imports coordinated by National Grid.

✅ Baseload from nuclear and biomass; intermittent wind and solar

✅ Interconnectors trade zero carbon imports via subsea cables

✅ Data from BMRS and ESO covers embedded energy estimates

 

Great Britain has one of the most diverse ranges of electricity generation in Europe, with everything from windfarms off the coast of Scotland to a nuclear power station in Suffolk tasked with keeping the lights on. The increasing reliance on renewable energy sources, as part of the country’s green ambitions, also means there can be rapid shifts in the main source of electricity generation. On windy days, most electricity generation comes from record wind generation across onshore and offshore windfarms. When conditions are cold and still, gas-fired power stations known as peaking plants are called into action.

The electricity system in Great Britain relies on a combination of “baseload” power – from stable generators such as nuclear and biomass plants – and “intermittent” sources, such as wind and solar farms that need the right weather conditions to feed energy into the grid. National Grid also imports energy from overseas, through subsea cables known as interconnectors that link to France, Belgium, Norway and the Netherlands. They allow companies to trade excess power, such as renewable energy created by the sun, wind and water, between different countries. By 2030 it is hoped that 90% of the energy imported by interconnectors will be from zero carbon energy sources, though low-carbon electricity generation stalled in 2019 for the UK.

The technology behind Great Britain’s power generation has evolved significantly over the last century, and at times wind has been the main source of electricity. The first integrated national grid in the world was formed in 1935 linking seven regions of the UK. In the aftermath of industrialisation, coal provided the vast majority of power, before oil began to play an increasingly important part in the 1950s. In 1956, the world’s first commercial nuclear reactor, Calder Hall 1 at Windscale (later Sellafield), was opened by Queen Elizabeth II. Coal use fell significantly in the 1990s while the use of combined cycle gas turbines grew, and in 2016 wind generated more electricity than coal for the first time. Now a combination of gas, wind, nuclear and biomass provide the bulk of Great Britain’s energy, with smaller sources such as solar and hydroelectric power also used. From October 2024, coal will no longer be used to generate electricity, following coal-free power records set in recent years.

Energy generation data is fetched from the Balancing Mechanism Reporting Service public feed, provided by Elexon – which runs the wholesale energy market – and is updated every five minutes, covering periods when wind led the power mix as well.

Elexon’s data does not include embedded energy, which is unmetered and therefore invisible to Great Britain’s National Grid. Embedded energy comprises all solar energy and wind energy generated from non-metered turbines. To account for these figures we use embedded energy estimates from the National Grid electricity system operator, which are published every 30 minutes.

Import figures refer to the net flow of electricity from the interconnectors with Europe and with Northern Ireland. A positive value represents import into the GB transmission system, while a negative value represents an export.

Hydro figures combine renewable run-of-the-river hydropower and pumped storage.

Biomass figures include Elexon’s “other” category, which comprises coal-to-biomass conversions and biomass combined heat and power plants.
