California should have adequate power supplies this summer, even if the state experiences warmer-than-normal temperatures, the California Energy Commission said in a summer outlook.

In the forecast, the Commission said ample resources should be available to meet peak loads and operating reserves will be sufficient even with a very warm summer.

The Commission, however, urged consumers to continue conserving electricity on hot afternoons, noting air conditioners use about 30 percent of total consumption during peak summer hours.

The outlook showed reserve margins, or the level of electricity supplies above demand, are about 22 percent for average weather conditions and 14 percent under hotter-than-normal weather.

California however is divided into regions north and south of Path 26, a transmission line area that frequently has constraints during periods of high electricity demand. Under hotter-than-normal temperatures, the Commission said supplies could be tight in Southern California with reserve margins dipping below the 15 percent to 17 percent target.

Power Outages to Mitigate Wildfire Risks

Colorado Wildfire Power Shutoffs reduce ignition risk through PSPS, grid safety protocols, data-driven forecasts, and emergency coordination, protecting communities, natural resources, and infrastructure during extreme fire weather fueled by drought and climate change.

 

Key Points

Planned PSPS outages cut power in high-risk areas to prevent ignitions, protect residents, and boost wildfire resilience.

✅ PSPS triggered by forecasts, fuel moisture, and fire danger indices.

✅ Utilities coordinate alerts, timelines, and critical facility support.

✅ Paired with forest management, education, and rapid response.

 

Colorado, known for its stunning landscapes and outdoor recreation, has implemented proactive measures to reduce the risk of wildfires by strategically shutting off power in high-risk areas, similar to PG&E wildfire shutoffs implemented in California during extreme conditions. This approach, while disruptive, aims to safeguard communities, protect natural resources, and mitigate the devastating impacts of wildfires that have become increasingly prevalent in the region.

The decision to initiate power outages as a preventative measure against wildfires underscores Colorado's commitment to proactive fire management and public safety, aligning with utility disaster planning practices that strengthen grid readiness. With climate change contributing to hotter and drier conditions, the state faces heightened wildfire risks, necessitating innovative strategies to minimize ignition sources and limit fire spread.

Utility companies, in collaboration with state and local authorities, identify areas at high risk of wildfire based on factors such as weather forecasts, fuel moisture levels, and historical fire data. When conditions reach critical thresholds, planned power outages, also known as Public Safety Power Shutoffs (PSPS), are implemented to reduce the likelihood of electrical equipment sparking wildfires during periods of extreme fire danger, particularly during windstorm-driven outages that elevate ignition risks.

While power outages are a necessary precautionary measure, they can pose challenges for residents, businesses, and essential services that rely on uninterrupted electricity, as seen when a North Seattle outage affected thousands last year. To mitigate disruptions, utility companies communicate outage schedules in advance, provide updates during outages, and coordinate with emergency services to ensure the safety and well-being of affected communities.

The implementation of PSPS is part of a broader strategy to enhance wildfire resilience in Colorado. In addition to reducing ignition risks from power lines, the state invests in forest management practices, wildfire prevention education, and emergency response capabilities, including continuity planning seen in the U.S. grid COVID-19 response, to prepare for and respond to wildfires effectively.

Furthermore, Colorado's approach to wildfire prevention highlights the importance of community preparedness and collaboration, and utilities across the region adopt measures like FortisAlberta precautions to sustain critical services during emergencies. Residents are encouraged to create defensible space around their properties, develop emergency evacuation plans, and stay informed about wildfire risks and response protocols. Community engagement plays a crucial role in building resilience and fostering a collective effort to protect lives, property, and natural habitats from wildfires.

The effectiveness of Colorado's proactive measures in mitigating wildfire risks relies on a balanced approach that considers both short-term safety measures and long-term fire prevention strategies. By integrating technology, data-driven decision-making, and community partnerships, the state aims to reduce the frequency and severity of wildfires while enhancing overall resilience to wildfire impacts.

Looking ahead, Colorado continues to refine its wildfire management practices in response to evolving environmental conditions and community needs, drawing on examples of localized readiness such as PG&E winter storm preparation to inform response planning. This includes ongoing investments in fire detection and monitoring systems, research into fire behavior and prevention strategies, and collaboration with neighboring states and federal agencies to coordinate wildfire response efforts.

In conclusion, Colorado's decision to implement power outages as a preventative measure against wildfires demonstrates proactive leadership in wildfire risk reduction and public safety. By prioritizing early intervention and community engagement, the state strives to safeguard vulnerable areas, minimize the impact of wildfires, and foster resilience in the face of increasing wildfire threats. As Colorado continues to innovate and adapt its wildfire management strategies, its efforts serve as a model for other regions grappling with the challenges posed by climate change and wildfire risks.

Electricity blackouts spark protests in Iranian cities

Iran Power Outage Protests surge as electricity blackouts, drought, and a looming heat wave spark unrest in Tehran, Shiraz, and more, with chants against leadership, strikes, and sanctions-driven economic pressures mounting.

 

Key Points

Protests across Iran over blackouts, drought, and economic strain challenge authorities and demand accountability.

✅ Rolling blackouts blamed on drought, heat wave, and surging demand.

✅ Chants target leadership amid strikes and wage, water shortages.

✅ Legitimacy questioned after low-turnout election and sanctions.

 

There have been protests in a number of cities in Iran amid rising public anger over widespread electricity blackouts.

Videos on social media appeared to show crowds in Shar-e Rey near Tehran, Shiraz, Amol and elsewhere overnight.

Some people can be heard shouting "Death to the dictator" and "Death to Khamenei" - a reference to Supreme Leader Ayatollah Ali Khamenei.

The government has apologised for the blackouts, which it has blamed on a severe drought and high demand.

Elsewhere, similar outages have had political repercussions, as a widespread power outage in Taiwan prompted a minister's resignation earlier this year.

President Hassan Rouhani explained in televised remarks on Tuesday morning that the drought meant most of the country's hydroelectric power plants were not operating, placing more pressure on thermal power plants, and that electricity consumption had surged as people used air conditioning to cope with the intense summer heat.

"I apologise to our dear people who have faced problems and suffering in the past few days and I urge them to co-operate [by cutting their electricity use]. People complain about power outages and they are right," Mr Rouhani said.

A video that has gone viral in recent days shows a woman complaining about the blackouts and corruption at a government office in the northern city of Gorgan and demanding that her comments be conveyed to "higher-ups like Mr Rouhani". "The only thing you have done is forcing hijab on us," she shouts.

The president has promised that the government will seek to resolve the problems within the next two or three weeks.

However, a power sector spokesman warned on Monday that consumption was exceeding the production capacity of Iran's power plants by 11GW, and said a "looming heat wave" could make the situation worse, as seen in Iraq's summer electricity crunch this year.

Iranians have also been complaining about water shortages and the non-payment of wages by some local authorities, while thousands of people working in Iran's oil industry have been on strike over pay and conditions, as officials discuss further energy cooperation with Iraq to ease supply pressures.

There was already widespread discontent at government corruption and the economic hardship caused by sanctions that were reinstated when the US abandoned a nuclear deal with Iran three years ago, even as Iran supplies about 40% of Iraq's electricity through cross-border sales.

Analysts say that after the historically low turnout in last month's presidential election, when more than half of the eligible voters stayed at home, the government is facing a serious challenge to its legitimacy.

Mr Rouhani will be succeeded next month by Ebrahim Raisi, a hard-line cleric close to Ayatollah Khamenei who won 62% of the vote after several prominent contenders were disqualified, while Iran finalizes power grid deals with Iraq to bolster regional ties.

The 60-year-old former judiciary chief has presented himself as the best person to combat corruption and solve Iran's economic problems, including ambitions to transmit electricity to Europe as a regional power hub.

But many Iranians and human rights activists have pointed to his human rights record, accusing him of playing a role in the executions of thousands of political prisoners in the 1980s and in the deadly crackdowns on mass anti-government protests in 2009 and 2019.

CALIFORNIA: Why your electricity prices are soaring

California Electricity Prices are surging across PG&E, SCE, and SDG&E territories, driven by fixed grid costs, wildfire mitigation, CARE subsidies, and Net Energy Metering, burdening low-income renters and increasing statewide utility debt, CPUC reports show.

 

Key Points

High rates driven by fixed grid costs and policies, burdening low-income customers across PG&E, SCE, and SDG&E.

✅ Fixed costs: transmission, distribution, wildfire mitigation

✅ Solar NEM shifts grid costs onto remaining ratepayers

✅ CPUC, CARE, LIHEAP aim to relieve rising utility debt

 

California's electricity prices are among the highest in the country, new research says, and those costs are falling disproportionately on a customer base that's already struggling to pay their bills.

PG&E customers pay about 80 percent more per kilowatt-hour than the national average, according to a study by the energy institute at UC Berkeley's Haas Business School with the nonprofit think tank Next 10. The study analyzed the rates of the state's three largest investor-owned utilities and found that Southern California Edison charged 45 percent more than the national average, while San Diego Gas & Electric charged double. Even low-income residents enrolled in the California Alternate Rates for Energy program paid more than the average American.

"California's retail prices are out of line with utilities across the country," said UC Berkeley assistant professor and study co-author Meredith Fowlie, citing Hawaii and some New England states among the outliers with even higher rates. "And they're increasing, as regulators face calls for action across the state."


So why are prices so high?
One reason is that California's size and geography inflate the "fixed" costs of operating its electric system, even as the state considers revamping electricity rates to clean the grid in parallel, which include maintenance, generation, transmission, and distribution as well as public programs like CARE and wildfire mitigation, according to the study. Those costs don't change based on how much electricity residents consume, yet between 66 and 77 percent of Californians' electricity bills are used to offset the costs of those programs, the study found.

These are legitimate expenses, Fowlie said. However, because lower-income residents use only moderately less electricity than higher income households, they end up with a disproportionate share of the burden, according to the study. And while the bills of older, wealthier Californians continue to decrease as they adopt cost-efficient alternatives like the state's Net Energy Metering solar program and the resulting solar power cost shift dynamic, costs will keep rising for a shrinking customer base composed mostly of low- and middle-income renters who still use electricity as their main energy source.

"When households adopt solar, they're not paying their fair share," Fowlie said. While solar users generate power that decreases their bills, they still rely on the state's electric grid for much of their power consumption - without paying for its fixed costs like others do.

"As this continues it's going to make electricity even more unaffordable," said F. Noel Perry, founder of Next 10, which funds nonpartisan research on the economy and environment.

PG&E this month raised its electricity rates 3.7 percent, amounting to a $5.01 a month increase for the average residential customer, who now pays $138.85 a month for electricity. It was the second increase this year, as regulators consider major changes to electric bills statewide, said Mark Toney, executive director of The Utility Reform Network, who noted that higher rates are particularly difficult for those who have lost their jobs in the pandemic. The California Public Utilities Commission last year approved a PG&E plan for more incremental increases through Dec. 31, 2022.

PG&E spokesperson Kristi Jourdan said in an email statement that the company was committed to keeping prices as low as possible as the state weighs income-based flat-fee utility bills proposals, and that although some programs are meant to be subsidized through rates, "in other cases, given that some customers have greater access to energy alternatives, the remaining customers - often those with limited means - are left paying unintended subsidies."

The costs quickly became overwhelming for Fretea Sylver, who rents a small house in Castro Valley and lost much of her work as the owner of a small woodwork business early in the pandemic. "They're little tiny changes but they accumulate. You turn around and you're like wait a second, why is my bill $20 more?," Sylver said. "And you have to pay it, no matter what."

Many more are unable to pay. Between February and December of last year, Californians accumulated more than $650 million in late payments from their utility providers, according to an analysis by the CPUC. In 2019, utility debt fell $71,646,869 from the prior year.

Sylver, who was on unemployment for 10 months last year, accumulated over $600 in unpaid PG&E bills. "We sort of went into a bit of debt, having to use credit cards and loans to sustain what we had to pay for. We're trying to catch up," Sylver said. The family received some help from the federal Low-Income Home Energy Assistance Program, which provides up to $1,000 to those who are late on their utility bills.

The study identified improvements to make California's power grid more equitable, such as income-based fixed electricity charges for the grid's cost that are based on income. Republican state senators this week called on the state to use federal relief money to forgive the billions Californians owe in utility debt, even as some lawmakers move to overturn income-based utility charges amid ongoing debate. Californians are currently protected by a statewide moratorium on disconnection for nonpayment of electricity bills through June 30. The CPUC this month began taking public input on the issue of how to grant some relief to those who have fallen behind on their utility bills.

Hydro One bends to government demands, caps CEO pay at $1.5M

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.

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.

Planning for our electricity future should be led by an independent body

Nova Scotia Integrated Resource Plan evaluates NSPI supply options, UARB oversight, Muskrat Falls imports, coal retirements, wind and biomass expansion, transmission upgrades, storage, and least-cost pathways to decarbonize the grid for ratepayers.

 

Key Points

A 25-year roadmap assessing supply, imports, costs, and emissions to guide least-cost decarbonization for Nova Scotia.

✅ Compares wind, biomass, gas, imports, and storage costs

✅ Addresses coal retirements, emissions caps, and reliability

✅ Recommends transmission upgrades and Muskrat Falls utilization

 

Maintaining a viable electricity network requires good long-term planning and, as a recent grid operations report notes, ongoing operational improvements. The existing stock of generating assets can become obsolete through aging, changes in fuel prices or environmental considerations. Future changes in demand must be anticipated.

Periodically, an integrated resource plan is created to predict how all this will add up during the ensuing 25 years. That process is currently underway and is led by Nova Scotia Power Inc. (NSPI) and will be submitted for approval to the Utilities and Review Board (UARB).

Coal-fired plants are still the largest single source of electricity in Nova Scotia. They need to be replaced with more environmentally friendly sources when they reach the end of their useful lives. Other sources include wind, hydroelectricity from rivers, biomass, as seen in increased biomass use by NS Power, natural gas and imports from other jurisdictions.

Imports are used sparingly today but will be an important source when the electricity from Muskrat Falls comes on stream. That project has big capacity. It can produce all the power needed in Newfoundland and Labrador (NL), where Quebec's power ambitions influence regional flows, plus the amount already committed to Nova Scotia, and still have a lot left over.

Some sources of electricity are more valuable than others. The daily amount of power from wind and solar cannot be controlled. Fuel-based sources and hydro can.

Utilities make their profits by providing the capital necessary to build infrastructure. Most of the money is borrowed but a portion, typically 30 per cent, usually comes from NSPI or a sister company. On that they receive a rate of return of nine per cent. Nova Scotia can borrow money today at less than two per cent.

The largest single investment of that type is the $1.577-billion Maritime Link connecting power from Newfoundland to Nova Scotia. It continues through to the New Brunswick border to facilitate exports to the United States. NSPI’s sister company, NSP Maritime Link Inc. (NSPML), is making nine per cent on $473 million of the cost.

There is little unexploited hydro capacity in Nova Scotia and there will not be any new coal-fired plants. Large-scale solar is not competitive in Nova Scotia’s climate. Nova Scotia’s needs would not accommodate the amount of nuclear capacity needed to be cost-effective, even as New Brunswick explores small reactors in its strategy.

So the candidates for future generating resources are wind, natural gas, biomass (though biomass criticism remains) and imports from other jurisdictions. Tidal is a promising opportunity but is still searching for a commercially viable technology. 

NSPI is commendably transparent about its process (irp.nspower.ca). At this stage there is little indication of the conclusions they are reaching but that will presumably appear in due course.

The mountains of detail might obscure the fact that NSPI is not an unbiased arbiter of choices for the future.

It is reported that they want to prematurely close the Trenton 5 coal plant in 2023-25. It is valued at $88.5 million. If it is closed early, ratepayers will still have to pay off the remaining value even though the plant will be idle. NSPI wants to plan a decommissioning of five of its other seven plants. There is a federal emissions constraint but retiring coal plants earlier than needed will cost ratepayers a lot.

Whenever those plants are closed, there will be a need for new sources of power. NSPI is proposing to plan for new investments in new transmission infrastructure to facilitate imports. Other possibilities would be additional wind farms, consistent with the shift to more wind and solar projects, thermal plants that burn natural gas or biomass, or storage for excess wind power that arrives before it can be used. The investment in storage could be anywhere from $20 million to $200 million.

These will add to the asset burden funded by ratepayers, even as industrial customers seek discounts while still paying for shuttered coal infrastructure.

External sources of new power will not provide NSPI the same opportunity: wind power by independent producers might be less expensive because they are willing to settle for less than nine per cent or because they are more efficient. Buying more power from Muskrat Falls will use transmission infrastructure we are already paying for. If a successful tidal technology is found, it will not be owned by NSPI or a sister company, which are no longer trying to perfect the technology.

This is not to suggest that NSPI would misrepresent the alternatives. But they can tilt the discussion in their favour. How tough will they be negotiating for additional Muskrat Falls power when it hurts their profits? Arguing for premature coal retirement on environmental grounds is fair game but whether the cost should be accepted is a political choice. 

NSPI is in a conflict of interest. We need a different process. An independent body should author the integrated resource plan. They should be fully informed about NSPI’s views.

They should communicate directly with Newfoundland and Labrador for Muskrat power, with independent wind producers, and with tidal power companies. The UARB cannot do any of these things.

The resulting plan should undergo the same UARB review that NSPI’s version would. This enhances the likelihood that Nova Scotians will get the least-cost alternative.
