California Rooftop Solar Rate Reforms propose shifting net metering to fixed access fees, peak-demand charges, and time-of-use pricing, aligning grid costs, distributed generation incentives, and retail rates for efficient, least-cost electricity and fair cost recovery.

Key Points

Policies replacing net metering with fixed fees, demand charges, and time-of-use rates to align costs and incentives.

✅ Large fixed access charge funds grid infrastructure

✅ Peak-demand pricing reflects capacity costs at system peak

✅ Time-varying rates align marginal costs and emissions

The California Public Service Commission has proposed revamping electricity rates for residential customers who produce electricity through their rooftop solar panels. In a recent New York Times op‐​ed, former Governor Arnold Schwarzenegger argued the changes pose an existential threat to residential rooftop solar. Interest groups favoring rooftop solar portray the current pricing system, often called net metering, in populist terms: “Net metering is the one opportunity for the little guy to get relief, and they want to put the kibosh on it.” And conventional news coverage suggests that because rooftop solar is an obvious good development and nefarious interests, incumbent utilities and their unionized employees, support the reform, well‐​meaning people should oppose it. A more thoughtful analysis would inquire about the characteristics and prices of a system that supplies electricity at least cost.

Currently, under net metering customers are billed for their net electricity use plus a minimum fixed charge each month. When their consumption exceeds their home production, they are billed for their net use from the electricity distribution system (the grid) at retail rates. When their production exceeds their consumption and the excess is supplied to the grid, residential consumers also are reimbursed at retail rates. During a billing period, if a consumer’s production equaled their consumption their electric bill would only be the monthly fixed charge.

Net metering would be fine if all the fixed costs of the electric distribution and transmission systems were included in the fixed monthly charge, but they are not. Between 66 and 77 percent of the expenses of California private utilities do not change when a customer increases or decreases consumption, but those expenses are recovered largely through charges per kWh of use rather than a large monthly fixed charge. Said differently, for every kWh that a PG&E solar household exported into the grid in 2019, it saved more than 26 cents, on average, while the utility’s costs only declined by about 8 cents or less including an estimate of the pollution costs of the system’s fossil fuel generators. The 18‐​cent difference pays for costs that don’t change with variation in a household’s consumptions, like much of the transmission and distribution system, energy efficiency programs, subsidies for low‐​income customers, and other fixed costs. Rooftop solar is so popular in California because its installation under a net metering system avoids the 18 cents, creating a solar cost shift onto non-solar customers. Rooftop solar is not the answer to all our environmental needs. It is simply a form of arbitrage around paying for the grid’s fixed costs.

What should electricity tariffs look like? This article in Regulation argues that efficient charges for electricity would consist of three components: a large fixed charge for the distribution and transmission lines, meter reading, vegetation trimming, etc.; a peak‐​demand charge related to your demand when the system’s peak demand occurs to pay for fixed capacity costs associated with peak use; and a charge for electricity use that reflects the time‐ and location‐​varying cost of additional electricity supply.

Actual utility tariffs do not reflect this ideal because of political concerns about the effects of large fixed monthly charges on low‐​income customers and the optics of explaining to customers that they must pay 50 or 60 dollars a month for access even if their use is zero. Instead, the current pricing system “taxes” electricity use to pay for fixed costs. And solar net metering is simply a way to avoid the tax. The proposed California rate reforms would explicitly impose a fixed monthly charge on rooftop solar systems that are also connected to the grid, a change that could bring major changes to your electric bill statewide, and would thus end the fixed‐​cost avoidance. Any distributional concerns that arise because of the effect of much larger fixed charges on lower‐​income customers could be managed through explicit tax deductions that are proportional to income.

The current rooftop solar subsidies in California also should end because they have perverse incentive effects on fossil fuel generators, even as the state exports its energy policies to neighbors. Solar output has increased so much in California that when it ends with every sunset, natural gas generated electricity has to increase very rapidly. But the natural gas generators whose output can be increased rapidly have more pollution and higher marginal costs than those natural gas plants (so called combined cycle plants) whose output is steadier. The rapid increase in California solar capacity has had the perverse effect of changing the composition of natural gas generators toward more costly and polluting units.

The reforms would not end the role of solar power. They would just shift production from high‐​cost rooftop to lower‐​cost centralized solar production, a transition cited in analyses of why electricity prices are soaring in California, whose average costs are comparable with electricity production in natural gas generators. And they would end the excessive subsidies to solar that have negatively altered the composition of natural gas generators.

Getting prices right does not generate citizen interest as much as the misguided notion that rooftop solar will save the world, and recent efforts to overturn income-based utility charges show how politicized the debate remains. But getting prices right would allow the decentralized choices of consumers and investors to achieve their goals at least cost.

Brazil ICMS Tax Cap limits state VAT on fuels, natural gas, electricity, communications, and transit, promising short-term price relief amid inflation, with federal compensation to states and potential legal challenges affecting investments and ANP auctions.

Key Points

A policy capping state VAT at 17-18 percent on fuels, electricity, and services to temper prices and inflation.

✅ Caps VAT to 17-18% on fuels, power, telecom, transit

✅ Short-term relief; medium-long term impact uncertain

✅ Federal compensation; potential court challenges, investment risk

Brazil’s congress approved a bill that limits the ICMS tax rate that state governments can charge on fuels, natural gas, electricity, communications, and public transportation. 

Local lawyers told BNamericas that the measure may reduce fuel and power prices in the short term, similar to Brazil power sector relief loans seen during the pandemic, but it is unlikely to produce any major effects in the medium and long term. 

In most states the ceiling was set at 17% or 18% and the federal government will pay compensation to the states for lost tax revenue until December 31, via reduced payments on debts that states owe the federal government.

The bill will become law once signed by President Jair Bolsonaro, who pushed strongly for the proposal with an eye on his struggling reelection campaign for the October presidential election. Double-digit inflation has turned into a major election issue and fuel and electricity prices have been among the main inflation drivers, as seen in EU energy-driven inflation across the bloc this year. Congress’ approval of the bill is seen by analysts as political victory for the Brazilian leader.

How much difference will it make?

Marcus Francisco, tax specialist and partner at Villemor Amaral Advogados, said that in the formation of fuel and electricity prices there are other factors, including high natural gas prices, that drive increases.

“In the case of fuels, if the barrel of oil [price] increases, automatically the final price for the consumer will go up. For electricity, on the other hand, there are several subsidies and policy choices such as Florida rejecting federal solar incentives that are part of the price and that can increase the rate [paid],” he said. 

There is also a possibility that some states will take the issue to the supreme court since ICMS is a key source of revenue for them, Francisco added.

Tiago Severini, a partner at law firm Vieira Rezende, said the comparison between the revenue impact and the effective price reduction, based on the estimates made by the states and the federal government, seems disproportionate, and, as seen in Europe, rolling back European electricity prices is often tougher than it appears. 

“In other words, a large tax collection impact is generated, which is quite unequal among the different states, for a not so strong price reduction,” he said.

“Due to the lack of clarity regarding the precision of the calculations involved, it’s difficult even to assess the adequacy of the offsets the federal government has been considering, and international cases such as France's new electricity pricing scheme illustrate how complex it can be to align fiscal offsets with regulatory constraints, to cover the cost it would have with the compensation for the states” Severini added.

The compensation ideas that are known so far include hiking other taxes, such as the social contribution on net profits (CSLL) that is paid by oil and gas firms focused on exploration and production.

“This can generate severe adverse effects, such as legal disputes, reduced investments in the country, and reduced attractiveness of the new auctions by [sector regulator] ANP, and costly interventions like the Texas electricity market bailout after extreme weather events,” Severini said.

Ukraine Electricity Imports surge to record levels as EU neighbors bolster grid stability amid Russian strikes, supporting energy security, preventing blackouts, and straining cross-border transmission capacity while Ukraine rebuilds damaged infrastructure and diversifies with renewables.

Key Points

Emergency EU power purchases stabilizing Ukraine’s grid after war damage.

✅ Record 19,000 MWh per day from EU interconnectors

✅ Supports grid stability and blackout prevention

✅ Cost and transmission upgrades challenge sustainability

Russia's ongoing war in Ukraine has extended far beyond the battlefield, with critical infrastructure becoming a target. Ukraine's once-robust energy system has sustained significant damage amid energy ceasefire violations and Russian missile and drone strikes. To cope with these disruptions and maintain power supplies for Ukrainian citizens, the country is turning to record-breaking electricity imports from neighboring European nations.

Prior to the war, Ukraine enjoyed a self-sufficient energy sector, even exporting electricity to neighboring countries. However, targeted attacks on power plants and transmission lines have crippled generation capacity. The situation is particularly dire in eastern and southern Ukraine, where ongoing fighting has caused extensive damage.

Faced with this energy crisis, Ukraine is looking to Europe for a lifeline. The country's energy ministry has announced plans to import a staggering amount of electricity – exceeding 19,000 megawatt-hours (MWh) per day – to prepare for winter and stabilize supplies. This surpasses the previous record set in March 2024 and represents a significant increase in Ukraine's reliance on external power sources.

Several European nations are stepping up to support Ukraine. Countries like Poland, Slovakia, Romania, Hungary, which maintains quiet energy ties with Russia today, and Moldova have agreed to provide emergency electricity supplies. These imports will help stabilize Ukraine's power grid and prevent widespread blackouts, especially during peak consumption hours.

The reliance on imports, however, presents its own set of challenges. Firstly, the sheer volume of electricity needed puts a strain on the capacity of neighboring grids. Upgrading and expanding transmission infrastructure will be crucial to ensure a smooth flow of electricity. Secondly, the cost of imported electricity can be higher than domestically generated power amid price hikes and instability globally, placing additional pressure on Ukraine's already strained finances.

Beyond these immediate concerns, the long-term implications of relying on external energy sources need to be considered. Ukraine's long-term goal is to rebuild its own energy infrastructure and regain energy independence. International assistance, including energy security support measures, will be crucial in this endeavor. Financial aid and technical expertise can help Ukraine repair damaged power plants, diversify its energy mix through further investment in renewables, and develop more resilient grid infrastructure.

The war in Ukraine has underscored the importance of energy security. A nation's dependence on a single source of energy, be it domestic or foreign, leaves it vulnerable to disruption, as others consider national security and fossil fuels in their own policies. For Ukraine, diversification and building a more resilient energy infrastructure are key takeaways from this crisis.

The international community also has a role to play. Supporting Ukraine's energy sector not only helps the nation weather the current crisis but also strengthens European energy security as a whole, where concerns over Europe's energy nightmare remain pronounced. A stable and independent Ukraine, less reliant on Russian energy, contributes to a more secure and prosperous Europe.

As the war in Ukraine continues, the battle for energy security rages on. While the immediate focus is on keeping the lights on through imports, the long-term goal for Ukraine is to rebuild a stronger, more resilient energy sector that can power the nation's future. The international community's support will be crucial in helping Ukraine achieve this goal.

Ireland Coal-Free Electricity Record: EirGrid reports 25 days without coal on the all-island grid, as wind power, renewables, and natural gas dominated generation, cutting CO2 emissions, with Moneypoint sidelined by market competitiveness.

Key Points

It is a 25-day period when the grid used no coal, relying on gas and renewables to reduce CO2 emissions.

✅ 25 days coal-free between April 11 and May 7

✅ Gas 60%, renewables 30% of generation mix

✅ Eurostat: 6.8% drop in Ireland's CO2 emissions

The island of Ireland has gone a record length of time without using coal-fired electricity generation on its power system, Britain's week-long coal-free run providing a recent comparator, Eirgrid has confirmed.

The all-island grid operated without coal between April 11th and May 7th – a total of 25 days, it confirmed. This is the longest period of time the grid has operated without coal since the all-island electricity market was introduced in 2007, echoing Britain's record coal-free stretch seen recently.

Ireland’s largest generating station, Moneypoint in Co Clare, uses coal, with recent price spikes in Ireland fueling concerns about dispatchable capacity, as do some of the larger generation sites in Northern Ireland.

The analysis coincides with the European statistics agency, Eurostat publishing figures showing annual CO2 emissions in Ireland fell by 6.8 per cent last year; partly due to technical problems at Moneypoint.

Over the 25-day period, gas made up 60 per cent of the fuel mix, while renewable energy, mainly wind, accounted for 30 per cent, echoing UK wind surpassing coal in 2016 across the market. Coal-fired generation was available during this period but was not as competitive as other methods.

EirGrid group chief executive Mark Foley said this was “a really positive development” as coal was the most carbon intense of all electricity sources, with its share hitting record lows in the UK in recent years.

“We are acutely aware of the challenges facing the island in terms of meeting our greenhouse gas emission targets, mindful that low-carbon generation stalled in the UK in 2019, through the deployment of more renewable energy on the grid,” he added.

Last year 33 per cent of the island’s electricity came from renewable energy sources, German renewables surpassing coal and nuclear offering a parallel milestone, a new record. Coal accounted for 9 per cent of electricity generation, down from 12.9 per cent in 2017.

Nation Rise Wind Farm Ruling overturns Ontario cancellation, as Superior Court finds the minister's decision unreasonable; EDP Renewables restarts 100-megawatt project near Cornwall, citing jobs, clean energy, and procedural fairness over bat habitat concerns.

Key Points

Ontario court quashes cancellation, letting EDP Renewables finish 100 MW Nation Rise project and resume clean energy.

✅ Judges call minister's decision unreasonable, unfair

✅ EDP Renewables to restart construction near Cornwall

✅ 100 MW, 29 turbines; costs awarded, appeal considered

Construction of a wind farm in eastern Ontario, as wind power makes gains nationwide, will move ahead after a court quashed a provincial government decision to cancel the project.

In a ruling released Wednesday, a panel of Ontario Superior Court judges said the province's decision to scrap the Nation Rise Wind Farm in December 2019 did not meet the proper requirements.

At the time, Environment Minister Jeff Yurek revoked the approvals of the project near Cornwall, Ont., citing the risk to three bat species.

That decision came despite a ruling from the province's Environmental Review Tribunal that determined the risk the project posed to the bat population was negligible.

The judges said the minister's decision was "unreasonable" and "procedurally unfair."

"The decision does not meet requirements of transparency, justification, and intelligibility, as the Minister has failed to adequately explain his decision," the judges wrote in their decision.

The company behind the project, EDP Renewables, said the 29-turbine wind farm was almost complete when its approval was revoked in December, even as Alberta saw TransAlta scrap a wind farm in a separate development.

The company said Thursday it plans to restart construction on the 100-megawatt wind farm.

"EDPR is eager to recommence construction of the Nation Rise Wind Farm, which will bring much-needed jobs and investment to the community," the company said in a statement. "This delay has resulted in unnecessary expenditures to-date, at a time when governments and businesses should be focused on reducing costs and restarting the economy."

A spokesman for Yurek said the government is disappointed with the outcome of the case but did not comment on a possible appeal.

"At this time, we are reviewing the decision and are carefully considering our next steps," Andrew Buttigieg said in a statement.

NDP climate change critic Peter Tabuns said the court decision is an embarrassment for the minister and the government. He urged the government not to pursue an appeal.

Yurek "was found to have ignored the evidence and the facts," he said. "They didn't just lose, their case collapsed. They had nothing to stand on. Taking this to appeal would be a complete and total waste of money."

Green party Leader Mike Schreiner said the ruling proves the government was acting based on ideology over evidence when it revoked the project's approval.

"As we shift towards a post-COVID recovery, we need the Ford government to give up the irrational crusade against affordable and reliable clean energy," Schreiner said in a statement.

Last year, the NDP revealed the province had spent $231 million to cancel more than 750 renewable energy contracts, a move Ford said he was proud of, shortly after winning the 2018 election.

The Progressive Conservatives have blamed the previous Liberal government, as leadership candidates debate how to fix power, for signing the bad energy deals while the province had an oversupply of electricity.

The Ford government, amid a new stance on wind power, has also said that by cancelling the contracts it would ultimately save ratepayers $790 million -- a figure industry officials have disputed.

At the time of the wind farm cancellation, the government also said it would introduce legislation that would protect consumers from any costs incurred, though a developer warned cancellations could exceed $100M at the time.

It has since acknowledged it will have to pay some companies to cancel the deals and set aside $231 million to reach agreements with those firms, and more recently has moved to reintroduce renewable projects in some cases.

On Wednesday, the judges awarded Nation Rise $126,500 in costs, which the government will have to pay.

Power Grid Attacks surge across substations and transmission lines, straining critical infrastructure as DHS and FBI cite vandalism, domestic extremists, and cybersecurity risks impacting resilience, outages, and grid reliability nationwide.

Key Points

Power Grid Attacks are deliberate strikes on substations and lines to disrupt power and weaken grid reliability.

✅ Physical attacks rose across multiple states and utilities.

✅ DHS and FBI warn of threats to critical infrastructure.

✅ Substation security and grid resilience upgrades urged.

Even before Christmas Day attacks on power substations in five states in the Pacific Northwest and Southeast, similar incidents of attacks, vandalism and suspicious activity were on the rise.

Federal energy reports through August – the most recent available – show an increase in physical attacks at electrical facilities across the nation this year, continuing a trend seen since 2017.

At least 108 human-related events were reported during the first eight months of 2022, compared with 99 in all of 2021 and 97 in 2020. More than a dozen cases of vandalism have been reported since September.

The attacks have prompted a flurry of calls to better protect the nation's power grid, with a renewed focus on protecting the U.S. power grid across sectors, but experts have warned for more than three decades that stepped-up protection was needed.

Attacks on power stations on the rise 
Twice this year, the Department of Homeland Security warned "a heightened threat environment" remains for the nation, including its critical infrastructure amid reports of suspected Russian breaches of power plant systems. 

At least 20 actual physical attacks were reported, compared with six in all of 2021. 
Suspicious-activity reports jumped three years ago, nearly doubling in 2020 to 32 events. In the first eight months of this year, 34 suspicious incidents were reported.
Total human-related incidents – including vandalism, suspicious activity and cyber events such as Russian hackers and U.S. utilities in recent years – are on track to be the highest since the reports started showing such activity in 2011.

Attacks reported in at least 5 states
Since September, attacks or potential attacks have been reported on at least 18 additional substations and one power plant in Florida, Oregon, Washington and the Carolinas. Several involved firearms.

• In Florida: Six "intrusion events" occurred at Duke Energy substations in September, resulting in at least one brief power outage, according to the News Nation television network, which cited a report the utility sent to the Energy Department. Duke Energy spokesperson Ana Gibbs confirmed a related arrest, but the company declined to comment further.
• In Oregon and Washington state: Substations were attacked at least six times in November and December, with firearms used in some cases, local news outlets reported. On Christmas Day, four additional substations were vandalized in Washington State, cutting power to more than 14,000 customers.
• In North Carolina: A substation in Maysville was vandalized on Nov. 11. On Dec. 3, shootings that authorities called a "targeted attack" damaged two power substations in Moore County, leaving tens of thousands without power amid freezing temperatures.
• In South Carolina: Days later, gunfire was reported near a hydropower plant, but police said the shooting was a "random act."

It's not yet clear whether any of the attacks were coordinated. After the North Carolina attacks, a coordinating council between the electric power industry and the federal government ordered a security evaluation.

FBI mum on its investigations
The FBI is looking into some of the attacks, including cyber intrusions where hackers accessed control rooms in past cases, but it hasn't said how many it's investigating or where. 

Shelley Lynch, a spokesperson for the FBI's Charlotte field office, confirmed the bureau was investigating the North Carolina attack. The Kershaw County Sheriff's Office reported the FBI was looking into the South Carolina incident.

Utilities in Oregon and Washington told news outlets they were cooperating with the FBI, but spokespeople for the agency's Seattle and Portland field offices said they couldn't confirm or deny an investigation.

Could domestic extremists be involved?
In January, the Department of Homeland Security said domestic extremists had been developing "credible, specific plans" since at least 2020, including a Neo-Nazi plot against power stations detailed in a federal complaint, and would continue to "encourage physical attacks against electrical infrastructure."

In February, three men who ascribed to white supremacy and Neo-Nazism pleaded guilty to federal crimes related to a scheme to attack the grid with rifles.

In a news release, Timothy Langan, assistant director of the FBI’s Counterterrorism Division, said the defendants "wanted to attack regional power substations and expected the damage would lead to economic distress and civil unrest."

Why is the power grid so hard to protect?
Industry experts, federal officials and others have warned in one report after another since at least 1990 that the power grid was at risk, and a recent grid vulnerability report card highlights dangerous weak points, said Granger Morgan, an engineering professor at Carnegie Mellon University who chaired three National Academies of Sciences reports.

The reports urged state and federal agencies to collaborate to make the system more resilient to attacks and natural disasters such as hurricanes and storms. 

"The system is inherently vulnerable, with the U.S. grid experiencing more blackouts than other developed nations in one study. It's spread all across the countryside," which makes the lines and substations easy targets, Morgan said. The grid includes more than 7,300 power plants, 160,000 miles of high-voltage power lines and 55,000 transmission substations.

One challenge is that there's no single entity whose responsibilities span the entire system, Morgan said. And the risks are only increasing as the grid expands to include renewable energy sources such as solar and wind, he said.
