The administration of Gov. Deval Patrick is urging the New England electric grid operator to allow the closure of the coal- and oil-fired Salem Harbor Power Station in Salem, Mass., according to a letter posted online by a Boston environmental nonprofit.

In response, a spokesman for the grid operator, ISO New England, said the organization is not blocking the closure and is looking for solutions that would eliminate the need for the plant.

The company that owns the Salem power plant, Dominion Resources Inc. of Virginia, said in November that the plant is expected to close within five years. But ISO has signaled that this could pose problems for the reliability of the grid, since the 745-megawatt Salem Harbor plant is among the stateÂ’s largest sources of power.

In a recent letter to ISO New England — posted by the Conservation Law Foundation — state energy and environmental secretary Ian Bowles asked that “all cost effective options” be considered to “allow Salem Harbor to be retired while safeguarding reliability.”

“I am concerned that if Salem Harbor is not allowed to retire, Dominion Energy will be forced to spend hundreds of millions of dollars on environmental upgrades to extend the life of an outmoded plant,” Bowles wrote.

“In my view, Massachusetts consumer dollars should be invested in clean energy solutions — better transmission, efficiency, conservation and renewables — rather than in keeping open an older generation coal plant that cannot compete economically and struggles to meet standards necessary to protect our environmental and public health,” wrote Bowles, who leaves the Patrick Administration at the end of the year.

In a recent e-mail, ISO spokesman Marcia Blomberg said that “the ISO is not preventing Dominion from retiring its Salem Harbor units, and we don’t have the authority to do so.”

“The ISO is aware of the situation and in accordance with our responsibility to ensure reliability, we have been studying the power system needs on the North Shore,” she said. “We are working with the utility companies to design and implement a transmission solution that will eliminate the reliability need for Salem Harbor.”

Dominion spokesman Dan Genest said previously that the company is basing its Salem Harbor closure plans on the expectation that the U.S. Environmental Protection agency will put stricter regulations on nitrogen oxide and sulfur dioxide emissions in place by 2015 or 2017.

Genest said the company hasn’t set a date for closing the plant, which has been open since 1951 and employs 145 people. The company could see scenarios in which the plant does not end up closing, he said — such as if the EPA regulations are delayed, or if ISO rules that the plant is crucial for grid reliability.

Environmental advocates, such as the Conservation Law Foundation, have called for Salem Harbor to either close or put stronger environmental measures put in place. In June, the organization filed a federal lawsuit alleging hundreds of violations of the U.S. Clean Air Act at the power plant in recent years.

Coal plant operators around the U.S. have also been under increasing pressure from government and public scrutiny due to climate change, since coal produces the largest amount of carbon dioxide emissions of any power source.

A tidal project in Scottish waters just generated enough electricity to power nearly 4,000 homes

MeyGen Tidal Stream Project delivers record 13.8 GWh to Scotland's grid, showcasing renewable ocean energy. Simec Atlantis Energy's 6 MW array of tidal turbines advances EU power goals and plans an ocean-powered data center.

 

Key Points

A Scottish tidal energy array exporting record power, using four 1.5 MW turbines and driving renewable innovation.

✅ Delivered 13.8 GWh to the grid in 2019, a project record.

✅ Four 1.5 MW turbines in Phase 1A, 6 MW installed.

✅ Plans include an ocean-powered data center near site.

 

A tidal power project in waters off the north coast of Scotland, where Scotland’s wind farms also deliver significant output, sent more than 13.8 gigawatt hours (GWh) of electricity to the grid last year, according to an operational update issued Monday. This figure – a record – almost doubled the previous high of 7.4 GWh in 2018.

In total, the MeyGen tidal stream array has now exported more than 25.5 GWh of electricity to the grid since the start of 2017, according to owners Simec Atlantis Energy. Phase 1A of the project is made up of four 1.5 megawatt (MW) turbines.

The 13.8 GWh of electricity exported in 2019 equates to the average yearly electricity consumption of roughly 3,800 “typical” homes in the U.K., where wind power records have been set recently, according to the company, with revenue generation amounting to £3.9 million ($5.09 million).

Onshore maintenance is now set to be carried out on the AR1500 turbine used by the scheme, with Atlantis aiming to redeploy the technology in spring.

In addition to the production of electricity, Atlantis is also planning to develop an “ocean-powered data centre” near the MeyGen project.

The European Commission has described “ocean energy” as being both abundant and renewable, and milestones like the biggest offshore windfarm starting U.K. supply underscore wider momentum, too. It’s estimated that ocean energy could potentially contribute roughly 10% of the European Union’s power demand by the year 2050, according to the Commission.

While tidal power has been around for decades — EDF’s 240 MW La Rance Tidal Power Plant in France was built as far back as 1966, and the country’s first offshore wind turbine has begun producing electricity — recent years have seen a number of new projects take shape.

In December last year, Scottish tidal energy business Nova Innovation was issued with a permit to develop a project in Nova Scotia, Canada, aiming to harness the Bay of Fundy tides in the region further.

In an announcement at the time, the firm said a total of 15 tidal stream turbines would be installed by the year 2023. The project, according to the firm, will produce enough electricity to power 600 homes, as companies like Sustainable Marine begin delivering tidal energy to the Nova Scotia grid.

Elsewhere, a business called Orbital Marine Power is developing what it describes as the world’s most powerful tidal turbine, with grid-supplied output already demonstrated.

The company says the turbine will have a swept area of more than 600 square meters and be able to generate “over 2 MW from tidal stream resources.” It will use a 72-meter-long “floating superstructure” to support two 1 MW turbines.

California Utility Cuts Power to Massive Areas in Northern, Central California

PG&E Public Safety Power Shutoff curbs wildfire risk amid high winds, triggering California outages across Northern California and Bay Area counties; grid safety measures, outage maps, campus closures, and restoration timelines guide residents and businesses.

 

Key Points

A preemptive outage program by PG&E to reduce wildfire ignition during extreme wind events in California.

✅ Cuts power during red flag, high wind, dry fuel conditions

✅ Targets Northern California, Bay Area counties at highest risk

✅ Restoration follows inspections, weather all-clear, hazard checks

 

California utility Pacific Gas and Electric Co. (PG&E) has cut off power supply to hundreds of thousands of residents in Northern and Central California as a precaution to possible breakout of wildfires, a move examined in reasons for shutdowns by industry observers.

PG&E confirmed that about 513,000 customers in many counties in Northern California, including Napa, Sierra, Sonoma and Yuba, were affected in the first phase of Public Safety Power Shutoff, a preemptive measure it took to prevent wildfires believed likely to be triggered by strong, dry winds.

The utility said the decision to shut off power was, amid ongoing debate over nuclear's status in California, "based on forecasts of dry, hot and windy weather including potential fire risk."

"This weather event will last through midday Thursday, with peak winds forecast from Wednesday morning through Thursday morning and reaching 60 mph (about 96 km per hour) to 70 mph (about 112 km per hour) at higher elevations," it said, while abroad National Grid warnings about short supply have highlighted parallel reliability concerns.

PG&E noted that about 234,000 residents in mostly counties of San Francisco Bay Area such as Alameda, Alpine, Contra Costa, San Mateo and Santa Clara were impacted in the second phase of the power shutoff, as the state considers power plant closure delays with potential grid impacts, that began around noon in Wednesday.

The unprecedented power outages sweeping across Northern California has darkened homes and forced schools and business to close, even as the UK paused an emergency energy plan amid its own supply concerns.

University of California, Berkeley canceled all classes for Wednesday due to expected campus power loss over the next few days.

The university said it has received notice from PG&E, as China's power woes cloud U.S. solar supplies that could aid resilience, that "most of the core campus will be without power" possibly for 48 hours.

A freshman at California State University San Jose told Xinhua that their classes were canceled Wednesday as the campus was running out of power.

"I had to go home because even our dormitory went without electricity," the student added.

However, PG&E noted in an updated statement Wednesday night that only 4,000 customers would be affected in the third phase being considered for Kern County in Central California, compared to an earlier forecast of 43,000 people who would experience power outage.

The PG&E power shutoff was the largest preemptive measure ever taken to prevent wildfires in the state's history, and it comes as clean power grows while fossil declines across California's grid, highlighting broader transition challenges.

The San Francisco-based California utility was held responsible for poor management of its power lines that sparked fatal wildfires in Northern California and killed 86 people last year in what was called Camp Fire, the single-deadliest wildfire in California's history.

Several lawsuits and other requests for compensation from wildfire victims that amounted to billions of U.S. dollars forced the embattled the company to claim bankruptcy protection early this year.

Financial update from N.L energy corp. reflects pandemic's impact

Nalcor Energy Pandemic Loss underscores Muskrat Falls delays, hydroelectric risks, oil price shocks, and COVID-19 impacts, affecting ratepayers, provincial debt, timelines, and software commissioning for the Churchill River project and Atlantic Canada subsea transmission.

 

Key Points

A $171M Q1 2020 downturn linked to COVID-19, oil price collapse, and Muskrat Falls delays impacting schedules and costs.

✅ Q1 2020 profit swing: +$92M to -$171M amid oil price crash

✅ Muskrat Falls timeline slips; cost may reach $13.1B

✅ Software, workforce, COVID-19 constraints slow commissioning

 

Newfoundland and Labrador's Crown energy corporation reported a pandemic-related profit loss from the first quarter of 2020 on Tuesday, along with further complications to the beleaguered Muskrat Falls hydroelectric project.

Nalcor Energy recorded a profit loss of $171 million in the first quarter of 2020, down from a $92 million profit in the same period last year, due in part to falling oil prices during the COVID-19 pandemic.

The company released its financial statements for 2019 and the first quarter of 2020 on Tuesday, and officials discussed the numbers in a livestreamed presentation that detailed the impact of the global health crisis on the company's operations.

The loss in the first quarter was caused by lower profits from electricity sales and a drop in oil prices due to the pandemic and other global events, company officials said.

The novel coronavirus also added to the troubles plaguing the Muskrat Falls hydroelectric dam on Labrador's Churchill River, amid Quebec-N.L. energy tensions that long predate the pandemic.

Work at the remote site stopped in March over concerns about spreading the virus. Operations have been resuming slowly, with a reduced workforce tackling the remaining jobs.

Officials with Nalcor said it will likely be another year before the megaproject is complete.

CEO Stan Marshall estimates the months of delays could bring the total cost to $13.1 billion including financing, up from the previous estimate of $12.7 billion -- though the total impact of the coronavirus on the project's price tag has yet to be determined.

"If we're going to shut down again, all of that's wrong," Marshall said. "But otherwise, we can just carry on and we'll have a good idea of the productivity level. I'm hoping that by September we'll have a more definitive number here."

The 824 megawatt hydroelectric dam will eventually send power to Newfoundland, and later Nova Scotia, through subsea cables, even as Nova Scotia boosts wind and solar in its energy mix.

It has seen costs essentially double since it was approved in 2012, and faced significant delays even before pandemic-forced shutdowns in North America and around the world this spring.

Cost and schedule overruns were the subject of a sweeping inquiry that held hearings last year, while broader generation choices like biomass use have drawn scrutiny as well.

The commissioner's report faulted previous governments for failing to protect residents by proceeding with the project no matter what, and for placing trust in Nalcor executives who "frequently" concealed information about schedule, cost and related risks.

Some of the latest delays have come from challenges with the development of software required to run the transmission link between Labrador and Newfoundland, where winter reliability issues have been flagged in reports.

The software is still being worked out, Marshall said Tuesday, and the four units at the dam will come online gradually over the next year.

"It's not an all or nothing thing," Marshall said of the final work stages.
Nalcor's financial snapshot follows a bleak fiscal update from the province this month. The Liberal government reported a net debt of $14.2 billion and a deficit of more than $1.1 billion, even as a recent Churchill Falls deal promised new revenues for the province, citing challenges from pandemic-related closures and oil production shutdowns.

Finance Minister Tom Osborne said at the time that help from Ottawa will be necessary to get the province's finances back on track.

Muskrat Falls represents about one-third of the province's debt, and is set to produce more power than the province of about half a million people requires. Anticipated rate increases due to the ballooning costs and questions about Muskrat Falls benefits have posed a significant political challenge for the provincial government.

Ottawa has agreed to work with Newfoundland and Labrador on a rewrite of the project's financial structure, scrapping the format agreed upon in past federal-provincial loan agreements in order to ease the burden on ratepayers, while some argue independent planning would better safeguard ratepayers.

Marshall, a former Fortis CEO who was brought in to lead Nalcor in 2016, has called the project a "boondoggle" and committed to seeing it completed within four years. Though that plan has been disrupted by the pandemic, Marshall said the end is in sight.

"I'm looking forward to a year from now. And I hope to be gone," Marshall said.

Alberta Electricity market needs competition

Alberta Electricity Market faces energy-only vs capacity debate as transmission, distribution, and administration fees surge; rural rates rise amid a regulated duopoly of investor-owned utilities, prompting calls for competition, innovation, and lower bills.

 

Key Points

Alberta's electricity market is an energy-only system with rising delivery charges and limited rural competition.

✅ Energy-only design; capacity market scrapped

✅ Delivery charges outpace energy on monthly bills

✅ Rural duopoly limits competition and raises rates

 

Last week, Alberta’s new Energy Minister Sonya Savage announced the government, through its new electricity rules, would be scrapping plans to shift Alberta’s electricity to a capacity market and would instead be “restoring certainty in the electricity system.”


The proposed transition from energy only to a capacity market is a contentious subject as a market reshuffle unfolds across the province that many Albertans probably don’t know much about. Our electricity market is not a particularly glamorous subject. It’s complicated and confusing and what matters most to ordinary Albertans is how it affects their monthly bills.


What they may not realize is that the cost of their actual electricity used is often just a small fraction of their bill amid rising electricity prices across the province. The majority on an average electricity bill is actually the cost of delivering that electricity from the generator to your house. Charges for transmission, distribution and franchise and administration fees are quickly pushing many Alberta households to the limit with soaring bills.


According to data from Alberta’s Utilities Consumer Advocate (UCA), and alongside policy changes, in 2004 the average monthly transmission costs for residential regulated-rate customers was below $2. In 2018 that cost was averaging nearly $27 a month. The increase is equally dramatic in distribution rates which have more than doubled across the province and range wildly, averaging from as low as $10 a month in 2004 to over $80 a month for some residential regulated-rate customers in 2018.


Where you live determines who delivers your electricity. In Alberta’s biggest cities and a handful of others the distribution systems are municipally owned and operated. Outside those select municipalities most of Alberta’s electricity is delivered by two private companies which operate as a regulated duopoly. In fact, two investor-owned utilities deliver power to over 95 per cent of rural Alberta and they continue to increase their share by purchasing the few rural electricity co-ops that remained their only competition in the market. The cost of buying out their competition is then passed on to the customers, driving rates even higher.


As the CEO of Alberta’s largest remaining electricity co-op, I know very well that as the price of materials, equipment and skilled labour increase, the cost of operating follows. If it costs more to build and maintain an electricity distribution system there will inevitably be a cost increase passed on to the consumer. The question Albertans should be asking is how much is too much and where is all that money going with these private- investor-owned utilities, as the sector faces profound change under provincial leadership?


The reforms to Alberta’s electricity system brought in by Premier Klein in the late 1900s and early 2000s contributed to a surge in investment in the sector and led to an explosion of competition in both electricity generation and retail. 


More players entered the field which put downward pressure on electricity rates, encouraged innovation and gave consumers a competitive choice, even as a Calgary electricity retailer urged the government to scrap the overhaul. But the legislation and regulations that govern rural electricity distribution in Alberta continue to facilitate and even encourage the concentration of ownership among two players which is certainly not in the interests of rural Albertans.


It is also not in the spirit of the United Conservative Party platform commitment to a “market-based” system. A market-based system suggests more competition. Instead, what we have is something approaching a monopoly for many Albertans. The UCP promised a review of the transition to a capacity market that would determine which market would be best for Alberta, and through proposed electricity market changes has decided that we will remain an energy-only market.
Consumers in rural Alberta need electricity to produce the goods that power our biggest industries. Instead of regulating and approving continued rate increases from private multinational corporations, we need to drive competition and innovation that can push rates down and encourage growth and investment in rural-based industries and communities.

SC nuclear plant on the mend after a leak shut down production for weeks

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.

Venezuela: Electricity Recovery Continues as US Withdraws Diplomatic Staff

Venezuela Power Outage cripples the national grid after a massive blackout; alleged cyber attacks at Guri Dam and Caracas, damaged transmission lines, CORPOELEC restoration, looting, water shortages, and sanctions pressure compound recovery.

 

Key Points

A March 2019 blackout crippling Venezuela's grid amid alleged cyber attacks, equipment failures, and slow restoration.

✅ Power restored partially after 96 hours across all states

✅ Alleged cyber attacks at Guri Dam and Caracas systems

✅ CORPOELEC urges reduced load during grid stabilization

 

Venezuelan authorities continue working to bring back online the electric grid following a massive outage that started on Thursday, March 7.

According to on-the-ground testimonies and official sources, power finally began to reach Venezuela’s western states, including Merida and Zulia, on Monday night, around 96 hours after the blackout started. Electricity has now been restored at least in some areas of every state, with authorities urging citizens, as seen in Ukraine's efforts to keep lights on during crisis, to avoid using heavy usage devices while efforts to restore the whole grid continue.

President Nicolas Maduro gave a televised address on Tuesday evening, offering more details about the alleged attack against the country’s electrical infrastructure. According to Maduro, both the computerized system in the Guri Dam, on Thursday afternoon, and the central electrical “brain” in Caracas, on Saturday morning, suffered cyber attacks, while recovery was delayed by physical attacks against transmission lines and electrical substations, a pattern seen in power outages in western Ukraine as well.

“The recovery has been a miracle by CORPOELEC (electricity) workers” he said, vowing that a “battle” had been won.

Maduro claimed that the attacks were directed from Chicago and Houston and that more evidence would be presented soon. The Venezuelan president had announced on Monday that two arrests were made in connection to alleged acts of sabotage against the communications system in the Guri Dam.

Venezuela’s electrical grid has suffered from poor maintenance and sabotage in recent years, with infrastructure strained by under-investment and Washington’s economic sanctions further compounding difficulties, with parallels to electricity inequality in California highlighting broader systemic challenges, though causes differ.

The extended power outage saw episodes of lootings take place, especially in the Zulia capital of Maracaibo. Food warehouses, supermarkets and a shopping mall were targeted according to reports and footage on social media.

Isolated episodes of protests and lootings were also reported in other cities, including some sectors of Caracas. A video spread on social media appeared to show a violent confrontation in the eastern city of Maturin in which a National Guardsman was shot dead.

While electricity has been gradually restored, public transportation and other services have yet to be reactivated, a contrast with U.S. grid resilience during COVID-19 where power systems remained stable, with the government suspending work and school activities until Wednesday.

In Caracas, attention has now turned to water. Shortages started to be felt after the water pumping system in the nearby Tuy valley was shut down amid the electricity blackout, underscoring that electricity is civilization in conflict zones, as interdependent systems cascade. Authorities announced on Tuesday afternoon that the system was due to resume supplying water to the capital metropolitan region.

Some communities protested the lack of water on Monday and long queues formed at water distribution points, with local authorities looking to send water tanks to supply communities and guarantee the normal functioning of hospitals.

The Venezuelan government has yet to release any information concerning casualties in hospitals, with NGO Doctors for Health reporting 24 dead as of Monday night following alleged contact with multiple hospitals. Higher figures, including claims of 80 newborns dead in Maracaibo, have been denied by local sources.

Self-proclaimed “Interim President” Juan Guaido has blamed the electricity crisis on government mismanagement and corruption, dismissing the government’s cyber attack thesis on the grounds that the system is analog, and attributing the national outage to a lack of qualified personnel needed to reactivate the grid. However, these claims have been called into question by people with knowledge of the system.

Guaido called for street protests on Tuesday afternoon which saw small groups momentarily take to streets in Caracas and other cities, or banging pots and pans from windows.

The opposition-controlled National Assembly, which has been in contempt of court since 2016, approved a decree on Monday declaring a state of “national alarm,” blaming the government for the current crisis and issuing instructions for public officials and security forces.

Likewise on Tuesday, Venezuelan Attorney General Tarek William Saab announced that an investigation was being opened against Guaido regarding his alleged responsibility for the recent power outage. Saab explained that this investigation would add to the previous one, opened on January 29, as well as determine responsibilities in instigating violence.
