The California Energy Commission has temporarily withdrawn approval of a controversial solar power plant by NTR's Tessera Solar after opponents protested that the 663.5-megawatt Calico project had been improperly licensed.

California aims to get a third of its electricity from renewable energy by 2020 and the $2 billion plant is an important step toward that goal.

An attorney for California Unions for Reliable Energy had argued in a November 11 letter that the energy commission, which licenses large-scale solar thermal power plants, had not filed required written findings about Calico environmental consequences when it approved the project on October 28.

The order was issued November 19 and the commission will take up the decision again on December 1, but the Sierra Club told Reuters that the environmental group may mount a legal challenge to Calico due to its impact on the imperiled desert tortoise, fringe-toed lizard and other wildlife.

"We are considering litigation," Gloria D. Smith, a senior staff attorney with the Sierra Club in San Francisco, said in an email.

Calico is one of seven huge solar thermal power plants that the energy commission has licensed over the past three months so developers can begin construction by the end of the year to qualify for a federal cash grant that covers 30 percent of a project's cost.

Tessera has signed a contract to supply electricity generated by Calico to utility Edison International's Southern California Edison, which is counting on the project to help it meet its renewable energy targets.

Karen Douglas, the energy commission's chairman, issued an order withdrawing approval for Calico.

Douglas wrote that the withdrawal of approval did not mean that the commission agreed with the argument by the California Unions for Reliable Energy that its decision had been improper.

A Tessera representative did immediately not respond to a request for comment.

The company plans to deploy 26,540 solar dishes called Suncatchers at Calico. Resembling giant mirrored satellite receivers, each Suncatcher is 40 feet high and 38 feet wide and generates electricity by focusing the sun on a Stirling engine to heat hydrogen gas. As the gas expands, it drives pistons to generate electricity.

The commission approved Calico only after Tessera agreed to reduce its footprint nearly in half to 4,613 acres in Southern California's Mojave Desert. The revised configuration would reduce the impact on the desert tortoise by 79 percent, the commission said.

But in an October 20 letter to the commission, Smith argued that even a downsized project would prove devastating to protected wildlife.

"It would result in the deaths of scores of threatened desert tortoises, result in the local extinction of the Mojave fringe-toed lizard, destroy an exceedingly rare desert plant, obstruct bighorn sheep movement, risk the survival of local golden eagles and impact burrowing owls, desert kit fox, and American badger," Sierra Club's Smith wrote. "The mere fact that each of these species is even present on the Calico site is astounding."

Tessera also faces a challenge to its 709-megawatt Imperial Valley solar project to be built near the Mexican border. Last month, the Quechan Indian Tribe filed suit against the federal government over its approval of the power plant, contending that it would harm the flat-tailed horned lizard, an animal proposed for endangered species protection that is part of the tribe's creation story.

Pennsylvania residents could see electricity prices rise as much as 50 percent this winter

Pennsylvania Electric Rate Increases hit Peco, PPL, and Pike County, driven by natural gas costs and wholesale power markets; default rate changes, price to compare shifts, and time-of-use plans affect residential bills.

 

Key Points

Electric default rates are rising across Pennsylvania as natural gas costs climb, affecting Peco, PPL, and Pike customers.

✅ PPL, Peco, and Pike raising default rates Dec. 1

✅ Natural gas costs driving wholesale power prices

✅ Consider standard offer, TOU rates, and efficiency

 

Energy costs for electric customers are going up by as much as 50% across Pennsylvania next week, the latest manifestation of US electricity price increases impacting gasoline, heating oil, propane, and natural gas.

Eight Pennsylvania electric utilities are set to increase their energy prices on Dec. 1, reflecting the higher cost to produce electricity. Peco Energy, which serves Philadelphia and its suburbs, will boost its energy charge by 6.4% on Dec. 1, from 6.6 cents per kilowatt hour to about 7 cents per kWh. Energy charges account for about half of a residential bill.

PPL Electric Utilities, the Allentown company that serves a large swath of Pennsylvania including parts of Bucks, Montgomery, and Chester Counties, will impose a 26% increase on residential energy costs on Dec. 1, from about 7.5 cents per kWh to 9.5 cents per kWh. That’s an increase of $40 a month for an electric heating customer who uses 2,000 kWh a month.

Pike County Light & Power, which serves about 4,800 customers in Northeast Pennsylvania, will increase energy charges by 50%, according to the Pennsylvania Public Utility Commission.

“All electric distribution companies face the same market forces as PPL Electric Utilities,” PPL said in a statement. Each Pennsylvania utility follows a different PUC-regulated plan for procuring energy from power generators, and those forces can include rising nuclear power costs in some regions, which explains why some customers are absorbing the hit sooner rather than later, it said.

There are ways customers can mitigate the impact. Utilities offer a host of programs and grants to support low-income customers, and some states are exploring income-based fixed charges to address affordability, and they encourage anyone struggling to pay their bills to call the utility for help. Customers can also control their costs by conserving energy. It may be time to put on a sweater and weatherize the house.

Peco recently introduced time-of-use rates — as seen when Ontario ended fixed pricing — that include steep discounts for customers who can shift electric usage to late night hours — that’s you, electric vehicle owners.

There’s also a clever opportunity available for many Pennsylvania customers called the “standard offer” that might save you some real money, but you need to act before the new charges take effect on Dec. 1 to lock in the best rates.

Why are the price hikes happening?
But first, how did we get here?

Energy charges are rising for a simple reason: Fuel prices for power generators are increasing, and that’s driven mostly by natural gas. It’s pushing up electricity prices in wholesale power markets and has lifted typical residential bills in recent years.

“It’s all market forces right now,” said Nils Hagen-Frederiksen, PUC spokesperson. Energy charges are strictly a pass-through cost for utilities. Utilities aren’t allowed to mark them up.

The increase in utility energy charges does not affect customers who buy their energy from competitive power suppliers in deregulated electricity markets. About 27% of Pennsylvania’s 5.9 million electric customers who shop for electricity from third-party suppliers either pay fixed rates, whose price remains stable, or are on a variable-rate plan tied to market prices. The variable-rate electric bills have probably already increased to reflect the higher cost of generating power.

Most New Jersey electric customers are shielded for now from rising energy costs. New Jersey sets annual energy prices for customers who don’t shop for power. Those rates go into effect on June 1 and stay in place for 12 months. The current energy market fluctuations will be reflected in new rates that take effect next summer, said Lauren Ugorji, a spokesperson for Public Service Electric & Gas Co., New Jersey’s largest utility.

For each utility, its own plan
Pennsylvania has a different system for setting utility energy charges, which are also known as the “default rate,” because that’s the price a customer gets by default if they don’t shop for power. The default rate is also the same thing as the “price to compare,” a term the PUC has adopted so consumers can make an apples-to-apples comparison between a utility’s energy charge and the price offered by a competitive supplier.

Each of the state’s 11 PUC-regulated electric utilities prepares its own “default service plan,” that governs the method by which they procure power on wholesale markets. Electric distribution companies like Peco are required to buy the lowest priced power. They typically buy power in blind auctions conducted by independent agents, so that there’s no favoritism for affiliated power generators

Some utilities adjust charges quarterly, and others do it semi-annually. “This means that each [utility’s] resulting price to compare will vary as the market changes, some taking longer to reflect price changes, both up and down,” PPL said in a statement. PPL conducted its semi-annual auction in October, when energy prices were rising sharply.

Most utilities buy power from suppliers under contracts of varying durations, both long-term and short-term. The contracts are staggered so market price fluctuations are smoothed out. One utility, Pike County Power & Light, buys all its power on the spot market, which explains why its energy charge will surge by 50% on Dec. 1. Pike County’s energy charge will also be quicker to decline when wholesale prices subside, as they are expected to next year.

Peco adjusts its energy charge quarterly, but it conducts power auctions semi-annually. It buys about 40% of its power in one-year contracts, and 60% in two-year contracts, and does not buy any power on spot markets, said Richard G. Webster Jr., Peco’s vice president of regulatory policy and strategy.

“At any given time, we’re replacing about a third of our supplied portfolio,” he said.

The utility’s energy charge affects only part of the monthly bill. For a Peco residential electric customer who uses 700 kWh per month, the Dec. 1 energy charge increase will boost monthly bills by $2.94 per month, or 2.9%. For an electric heating customer who uses about 2,000 kWh per month, the change will boost bills $8.40 a month, or about 3.5%, said Greg Smore, a Peco spokesperson.

State-owned electricity generation firm could save Britons nearly 21bn a year?

Great British Energy could cut UK electricity costs via public ownership, investing in clean energy like wind, solar, tidal, and nuclear, curbing windfall profits, stabilizing bills, and reinvesting returns through a state-backed generator.

 

Key Points

A proposed state-backed UK generator investing in clean power to cut costs and return gains to taxpayers.

✅ Publicly owned investment in wind, solar, tidal, and nuclear

✅ Cuts electricity bills by reducing generators' windfall profits

✅ Funded via bonds or asset buyouts; non-profit operations

 

A publicly owned electricity generation firm could save Britons nearly £21bn a year, according to new analysis that bolsters Labour’s case to launch a national energy company if the party gains power.

Thinktank Common Wealth has calculated that the cost of generating electricity to power homes and businesses could be reduced by £20.8bn or £252 per household a year under state ownership, according to a report seen by the Guardian.

The Labour leader, Keir Starmer, has committed to creating “a publicly owned national champion in clean energy” named Great British Energy.

Starmer is yet to lay out the exact structure of the mooted company, although he has said it would not involve nationalising existing assets, or become involved in the transmission grid or retail supply of energy.

Starmer instead hopes to create a state-backed entity that would invest in clean energy – wind, solar, tidal, nuclear, large-scale storage and other emerging technologies – creating jobs and ensuring windfalls from the growth in low carbon power feed back to the government.

The Common Wealth report, which analysed scenarios for reforming the electricity market, said that a huge saving on electricity costs could be made by buying out assets such as wind, solar and biomass generators on older contracts and running them on a non-profit basis. Funding the measure could require a government bond issuance, or some form of compulsory purchase process.

Last year the government attempted to get companies operating low carbon generators, including nuclear power plants, on older contracts to switch to contracts for difference (CfD), allowing any outsized profits to flow back to taxpayers. However, the government later decided to tax eligible firms through the electricity generator levy instead.

The Common Wealth study concluded that a publicly owned low carbon energy generator would best deliver on Britain’s climate and economic goals, would eliminate windfall profits made by generators and would cut household bills significantly.

MPs and campaigners have argued that Britain’s energy companies should be nationalised since the energy crisis, even as coal-free records have multiplied and renewables still need more support, which has resulted in North Sea oil and gas producers and electricity generators making windfall profits, and a string of retail suppliers collapsing, costing taxpayers billions. Detractors of nationalisation in energy argue it can stifle innovation and expose taxpayers to huge financial risks.

Common Wealth pointed out that more than 40% of the UK’s offshore wind generation capacity was publicly owned by overseas national entities, meaning the benefits of high electricity prices linked to the war in Ukraine had flowed back to other governments.

The study found the publicly owned generator model would create more savings than other options, including a drive for voluntary CfDs; splitting the generation market between low carbon and fossil fuel sources at a time when wind and solar have outproduced nuclear, and a “single buyer model” with nationalised retail suppliers.

Electricity Payouts on Biggest U.S. Grid Fall 64 Per Cent in Auction

PJM Capacity Auction Price Drop signals PJM Interconnection capacity market shifts, with $50/MW-day clearing, higher renewables and nuclear participation, declining coal, natural gas pressure, and zone impacts in ComEd and EMAAC, amid 21% reserve margins.

 

Key Points

A decline to $50 per MW-day in PJM capacity prices, shifting resource mix, zonal rates, and reserve margins.

✅ Clearing price fell to $50/MW-day from $140 in 2018

✅ Renewables and nuclear up; coal units down across PJM

✅ Zonal prices: ComEd $68.96, EMAAC $97.86; 21% reserves

 

Power-plant owners serving the biggest U.S. grid will be paid 64% less next year for being on standby to keep the lights on from New Jersey to Illinois.

Suppliers to PJM Interconnection LLC’s grid, which serves more than 65 million people, will get $50 a megawatt-day to provide capacity for the the year starting June 2022, according to the results of an auction released Wednesday. That’s down sharply from $140 in the previous auction, held in 2018. Analysts had expected the price would fall to about $85.

“Renewables, nuclear and new natural gas generators saw the greatest increases in cleared capacity, while coal units saw the largest decrease,” PJM said in a statement.

The PJM auction is the single most important event for power generators across the eastern U.S., including Calpine Corp., NRG Energy Inc. and Exelon Corp., because it dictates a big chunk of their future revenue. It also plays a pivotal role in shaping the region’s electricity mix, determining how much the region is willing to stick with coal and natural gas plants or replace them with wind and solar even as the aging grid complicates progress nationwide.

The results showed that the capacity price for the Chicago-area zone, known as ComEd, was $68.96 compared with $195.55 in the last auction. The price for the Pennsylvania and New Jersey zone, known as EMAAC, fell to $97.86 percent, from $165.73. All told, 144,477 megawatts cleared, representing a reserve margin of 21%.

Exelon shares fell 0.4% after the results were released. Vistra fell 1.5%. NRG was unchanged.

Blackouts triggered by extreme weather in Texas and California over the last year have reignited a debate over whether other regions should institute capacity systems similar to the one used by PJM, and whether to adopt measures like emergency fuel stock programs in New England as well. The market, which pays generators to be on standby in case extra power is needed, has long been a source of controversy. While it makes the grid more reliable, the system drives up costs for consumers. In the area around Chicago, for instance, these charges total more than $1.7 billion per year, accounting for 20% of customer bills, according to the Illinois Clean Jobs Coalition.

In the 2018 auction, PJM contracted supplies that were about 22% in excess of the peak demand projection at the time. This year, the grid is projected to start summer with a reserve margin of about 26%, as COVID-19 demand shifts persist, according to the market monitor -- far higher than the 16% most engineers say is needed to prevent major outages.

“This certainly doesn’t seem fair to ratepayers,” said Ari Peskoe, director of Harvard Law School’s Electricity Law Initiative.

Fossil-Fuel Advantage
Heading into the auction, analysts expected coal and gas plants to have the advantage. Nuclear reactors and renewables, they said, were poised to struggle amid coal and nuclear disruptions nationwide.

That’s because this is the first PJM auction run under a major pricing change imposed by federal regulators during the Trump administration. The new structure creates a price floor for some bidders, effectively hobbling nuclear and renewables that receive state subsidies while making it easier for fossil fuels to compete.

Those rules triggered contentious wrangling between power providers, PJM and federal regulators, delaying the auction for two years. The new system, however, may be short lived. The Biden administration is moving to overhaul the rules in time for the next auction in December.

Dominion Energy Inc., one of the biggest U.S. utility owners, pulled out of the market over the rules. The Virginia-based company, which has a goal to have net-zero carbon emissions by 2050, said the new PJM format will “make renewables more expensive” than delivering clean energy through alternative markets.

Illinois, New Jersey and Maryland have also threatened to leave the capacity market unless the new price floor is eliminated, and Connecticut is leading a market overhaul in New England as well. PJM has already launched a process to do it.

PJM is already one of the most fossil-fuel intensive grids, with 60% of its electricity coming from coal and gas. Power plants that bid into the auction rely on it for the bulk of their revenue. That means plants that win contracts have an incentive to continue operating for as long as they can, even amid a supply-chain crisis this summer.

B.C. electricity demand hits an all-time high

BC Hydro Peak Electricity Demand reached a record 10,902 megawatts during a cold snap, driven by home heating. Peak hours surged; load shifting and energy conservation can ease strain on the grid and lower bills.

 

Key Points

Record winter peak of 10,902 MW, set during a cold snap, largely from home heating demand at peak hours.

✅ All-time high load: 10,902 MW between 5 and 6 p.m., Dec. 27.

✅ Cold snap increased home heating demand during peak hours.

✅ Shift laundry and dishwashers off-peak; use programmable thermostats.

 

BC Hydro says the province set a new record for peak electricity demand on Monday as temperatures hit extreme lows, and Quebec shattered consumption records during similar cold weather.

Between 5 and 6 p.m. on Dec. 27, demand for electricity hit an all-time high of 10,902 megawatts, which is higher than the previous record of 10,577 megawatts set in 2020, and follows a record-breaking year in 2021 for the utility.

“The record represents a single moment in the hour when demand for electricity was the highest yesterday,” says Simi Heer, BC Hydro spokesperson, in a statement. “Most of the increase is likely due to additional home heating required during this cold snap.”

In addition to the peak demand record on Monday, BC Hydro has observed an overall increase in electricity demand since Friday, and has noted that cryptocurrency mining electricity use is an emerging load in the province as well. Monday’s hourly peak demand was 18 per cent higher than Friday’s, while Calgary's electricity use soared during a frigid February, underscoring how cold snaps strain regional grids.

“BC Hydro has enough supply options in place to meet increasing electricity demand,” adds Heer, and pointed to customer supports like a winter payment plan for households managing higher bills. “However, if British Columbians want to help ease some of the demand on the system during peak times, we encourage shifting activities like doing laundry or running dishwashers to earlier in the day or later in the evening.”

BC Hydro is also offering energy conservation tips for people looking to lower their electricity use and their electricity bills, noting that Earth Hour once saw electricity use rise in the province:

Manage your home heating actively by turning the heat down when no one his home or when everyone is sleeping. Consider installing a programmable thermostat to automatically adjust temperatures at different times based on your family's activities, and remember that in warmer months wasteful air conditioning can add $200 to summer energy bills. BC Hydro recommends the following temperatures:

16 degrees Celsius when sleeping or away from home
21 degrees Celsius when relaxing, watching TV
18 degrees Celsius when doing housework or cleaning

Romania enhances safety at Cernavoda, IAEA reports

IAEA OSART Cernavoda highlights strengthened operational safety at Romania’s Cernavoda NPP, citing improved maintenance practices, simulator training, and deficiency reporting, with ongoing actions on spare parts procurement, procedure updates, and chemical control for nuclear compliance.

 

Key Points

An IAEA follow-up mission confirming improved operational safety at Cernavoda NPP, with remaining actions tracked.

✅ Enhanced simulator training and crew performance

✅ Improved field deficiency identification and reporting

✅ Ongoing upgrades to procedures, spares, and chemical control

 

The International Atomic Energy Agency (IAEA) said yesterday that the operator of Romania’s Cernavoda nuclear power plant had demonstrated "strengthened operational safety" by addressing the findings of an initial IAEA review in 2016. The Operational Safety Review Team (OSART) concluded a five-day follow-up mission on 8 March to the Cernavoda plant, which is on the Danube-Black Sea Canal, about 160 km from Bucharest.

The plant's two 706 MWe CANDU pressurised heavy water reactors, reflecting Canadian nuclear projects, came online in 1996 and 2007, respectively.

The OSART team was led by Fuming Jiang, a senior nuclear safety officer at the IAEA, which recently commended China's nuclear security in separate assessments.

"We saw improvements in key areas, such as the procurement of important spare parts, the identification and reporting of some deficiencies, and some maintenance work practices, as evidenced by relevant performance indicators," Jiang said, noting milestones at nuclear projects worldwide this year.

The team observed that several findings from the 2016 review had been fully addressed, including: enhanced operator crew performance during simulator training; better identification and reporting of deficiencies in the field; and improvement in maintenance work practices.

More time is required, it said, to fully implement some actions, including: further improvements in the procurement of important spare parts with relevance to safety; further enhancement in the revision and update of some operating procedures, drawing on lessons from Pickering NGS life extensions undertaken in Ontario; and control and labelling of some plant chemicals.

Dan Bigu, site vice president of Cernavoda NPP, said the 2016 mission had "proven to be very beneficial", adding that the current follow-up mission would "provide further catalyst support to our journey to nuclear excellence".

The team provided a draft report of the mission to the plant's management and a final report will be submitted to the Romanian government, which recently moved to terminate talks with a Chinese partner on a separate nuclear project, within three months.

OSART missions aim to improve operational safety by objectively assessing safety performance, even as the agency reports mines at Ukraine's Zaporizhzhia plant amid ongoing risks, using the IAEA's safety standards and proposing recommendations and suggestions for improvement where appropriate. The follow-up missions are standard components of the OSART programme and, as the IAEA has warned of risks from attacks on Ukraine's power grids, are typically conducted within two years of the initial mission.

Australia PM rules out taxpayer funded power plants amid energy battle

ACCC energy underwriting guarantee proposes government-backed certainty for new generation, cutting electricity prices and supporting gas, pumped hydro, renewables, batteries, and potentially coal-fired power, addressing market failure without direct subsidies.

 

Key Points

A tech-neutral, government-backed plan underwriting new generation revenue to increase certainty and cut power prices.

✅ Government guarantee provides a revenue floor for new generators.

✅ Technology neutral: coal, gas, renewables, pumped hydro, batteries.

✅ Intended to reduce bills by up to $400 and address market failure.

 

Australian Taxpayers won't directly fund any new power plants despite some Coalition MPs seizing on a new report to call for a coal-fired power station.

The Australian Competition and Consumer Commission recommended the government give financial certainty to new power plants, guaranteeing energy will be bought at a cheap price if it can't be sold, as part of an electricity market plan to avoid threats to supply.

It's part of a bid to cut up to $400 a year from average household power prices.

Prime Minister Malcolm Turnbull said the finance proposal had merit, but he ruled out directly funding specific types of power generation.

"We are not in the business of subsidising one technology or another," he told reporters in Queensland today.

"We've done enough of that. Frankly, there's been too much of that."

Renewable subsidies, designed in the 1990s to make solar and wind technology more affordable, have worked and will end in 2020.

Some Coalition MPs claim the ACCC's recommendation to underwrite power generation is vindication for their push to build new coal-fired power plants.

But ACCC chair Rod Sims said no companies had proposed building new coal plants - instead they're trying to build new gas projects, pumped hydro or renewable projects.

Opposition Leader Bill Shorten said Mr Turnbull was offering solutions years away, having overseen a rise in power prices over the past year.

"You don't just go down to K-Mart and get a coal-fired power station off the shelf," Mr Shorten told reporters, admitting he had not read the ACCC report.

Energy Minister Josh Frydenberg said the recommendation to underwrite new power generators had a lot of merit, as it would address a market failure highlighted by AEMO warnings about reduced reserves.

"What they're saying is the government needs to step in here to provide some sort of assurance," Mr Frydenberg told 9NEWS today.

He said that could include coal, gas, renewable energy or battery storage.

Deputy Nationals leader Bridget McKenzie said science should determine which technology would get the best outcomes for power bills, with a scrapping coal report suggesting it can be costly.

Mr Turnbull said there was strong support for the vast majority of the ACCC's 56 recommendations, but the government would carefully consider the report, which sets out a blueprint to cut electricity bills by 25 percent.

Acting Greens leader Adam Bandt said Australia should exit coal-fired power in favour of renewable energy to cut pollution.

In contrast, Canada has seen the Stop the Shock campaign advocate a return to coal power in some provinces.

The Australian Energy Council, which represents 21 major energy companies, said the government should consult on changes to avoid "unintended consequences".
