On the west side of the ridge where the Post Ranch Inn is perched, the sun dazzles guests as it sets over the Pacific Ocean.

On the other side, its rays are soaked up by two acres of solar panels and converted into electricity for the Big Sur resort's 40 guest rooms and other facilities.

Installation of the panels was completed about two months ago and since then they have provided about 90 percent of the resort's power.

Post Ranch, just south of Pfeiffer Big Sur State Park on Highway 1, had already built a reputation as one of the world's most ecologically sensitive hotels, so the decision to go solar was not a ploy to put the resort on the map. And while Post Ranch will possibly save money by using the new power source, it was not primarily a cost-saving move, said General Manager Dan Priano.

"We're more concerned about our carbon footprint," Priano said. "We've always been good stewards of the land. Even our Lexus vehicles are hybrids."

The inn's Lexus SUV fleet, used to transport guests between the parking lot and their rooms, is probably the resort's flashiest amenity.

Most of the resort's materials and designs exemplify the green-building philosophy, which emphasizes a low environmental impact and seamless integration into the natural landscape.

Structures are made of recycled redwood. Landscaping features drought-resistant native plants. A vegetable garden contributes to the restaurant's organic cuisine.

The rooms — which range from $550 to $2,200 a night — and other accommodations sit atop the 100-acre property, 1,200 feet above the coastline that makes up the resort's western boundary.

The solar panels are down the hill from the main facilities, closer to Highway 1. Wildlife is often seen roaming around the posts that hold the panels 3 1/2 feet to 15 feet off the ground. Most mornings, deer can be seen hanging out in the panel field, Priano said.

"Normally you see them laying out here," he said. "I think they see it as a shade room."

The 990 panels, which cover about two acres, are owned and operated by Recurrent Energy, a San Francisco-based developer and manager of solar power systems. The inn buys its electricity from Recurrent at a lower rate than what Pacific Gas & Electric Co. charges.

Recurrent Chief Executive Arno Harris said the agreement works out for both parties financially, because the inn did not have to pay for the installation and Recurrent receives monthly payments from Post Ranch.

"The thing that is great about this is working with a client that is so committed to their renewability goals," Harris said.

The solar panel field is expected to produce about 400,000 kilowatt-hours of electricity a year, which translates to savings of more than 600,000 pounds of carbon emissions that would be produced by fossil-fuel sources to power the resort.

On sunny days, when the panels produce more energy than is needed by the inn, the extra electricity is sold to PG&E, Priano said.

"Some days the meter is running backwards," he said.

The inn's Web site provides live updates of the solar array's energy output for each day, for the past month and for the past year.

Since being turned on in March, the panels have produced more than 63,000 kilowatt hours. They produced about 1,400 kilowatt hours on Tuesday, said the Web site's monitor.

In 2008, Post Ranch was ranked the eighth-best hotel in the continental U.S. and Canada by Travel and Leisure magazine. In 2003, Conde Nast Traveler magazine ranked it the best hotel in North America.

The inn's environmental stewardship has earned it a perennial spot among Trip Advisor's top 100 environmentally friendly accommodations in the world. It would meet the qualifications for Leadership in Energy and Environmental Design certification — a rating system employed by the U.S. Green Building Council — but the inn's executives have not pursued certification, Priano said.

"We just haven't done it," he said. "We just do our thing."

Ontario Energy minister downplays dispute between auditor, electricity regulator

Ontario IESO Accounting Dispute highlights tensions over public sector accounting standards, auditor general oversight, electricity market transparency, KPMG advice, rate-regulated accounting, and an alleged $1.3B deficit understatement affecting Hydro bills and provincial finances.

 

Key Points

A PSAS clash between Ontario's auditor general and the IESO, alleging a $1.3B deficit impact and transparency failures.

✅ Auditor alleges deficit understated by $1.3B

✅ Dispute over PSAS vs US-style accounting

✅ KPMG support, transparency and co-operation questioned

 

The bad blood between the Ontario government and auditor general bubbled to the surface once again Monday, with the Liberal energy minister downplaying a dispute between the auditor and the Crown corporation that manages the province's electricity market, even as the government pursued legislation to lower electricity rates in the province.

Glenn Thibeault said concerns raised by auditor general Bonnie Lysyk during testimony before a legislative committee last week aren't new and the practices being used by the Independent Electricity System Operator are commonly endorsed by major auditing firms.

"(Lysyk) doesn't like the rate-regulated accounting. We've always said we've relied on the other experts within the field as well, plus the provincial controller," Thibeault said.

#google#

"We believe that we are following public sector accounting standards."

Thibeault said that Ontario Power Generation, Hydro One and many other provinces and U.S. states use the same accounting practices.

"We go with what we're being told by those who are in the field, like KPMG, like E&Y," he said.

But a statement from Lysyk's office Monday disputed Thibeault's assessment.

"The minister said the practices being used by the IESO are common in other jurisdictions," the statement said.

"In fact, the situation with the IESO is different because none of the six other jurisdictions with entities similar to the IESOuse Canadian Public Sector Accounting Standards. Five of them are in the United States and use U.S. accounting standards."

Lysyk said last week that the IESO is using "bogus" accounting practices and her office launched a special audit of the agency late last year after the agency changed their accounting to be more in line with U.S. accounting, following reports of a phantom demand problem that cost customers millions.

Lysyk said the accounting changes made by the IESO impact the province's deficit, understating it by $1.3 billion as of the end of 2017, adding that IESO "stalled" her office when it asked for information and was not co-operative during the audit.

Lysyk's full audit of the IESO is expected to be released in the coming weeks and is among several accounting disputes her office has been engaged in with the Liberal government over the past few years.

Last fall, she accused the government of purposely obscuring the true financial impact of its 25% hydro rate cut by keeping billions in debt used to finance that plan off the province's books. Lysyk had said she would audit the IESO because of its role in the hydro plan's complex accounting scheme.

"Management of the IESO and the board would not co-operate with us, in the sense that they continually say they're co-operating, but they stalled on giving us information," she said last week.

Terry Young, a vice-president with the IESO, said the agency has fully co-operated with the auditor general. The IESO opened up its office to seven staff members from the auditor's office while they did their work.

"We recognize the work that she's doing and to that end we've tried to fully co-operate," he said. "We've given her all of the information that we can."

Young said the change in accounting standards is about ensuring greater transparency in transactions in the energy marketplace.

"It's consistent with many other independent electricity system operators are doing," he said.

Lysyk also criticized IESO's accounting firm, KPMG, for agreeing with the IESO on the accounting standards. She was critical of the firm billing taxpayers for nearly $600,000 work with the IESO in 2017, compared to their normal yearly audit fee of $86,500.

KPMG spokeswoman Lisa Papas said the accounting issues that IESO addressed during 2017 were complex, contributing to the higher fees.

The accounting practices the auditor is questioning are a "difference of professional judgement," she said.

"The standards for public sector organizations such as IESO are principles-based standards and, accordingly, require the exercise of considerable professional judgement," she said in a statement.

"In many cases, there is more than one acceptable approach that is compliant with the applicable standards."

Progressive Conservative energy critic Todd Smith said the government isn't being transparent with the auditor general or taxpayers, aligning with calls for cleaning up Ontario's hydro mess in the sector.

"Obviously, they have some kind of dispute but the auditor's office is saying that the numbers that the government is putting out there are bogus.

Those are her words," he said. "We've always said that we believe the auditor general's are the true numbers for the
province of Ontario."

NDP energy critic Peter Tabuns said the Liberal government has decided to "play with accounting rules" to make its books look better ahead of the spring election, despite warnings that electricity prices could soar if costs are pushed into the future.

UK homes can become virtual power plants to avoid outages

Demand Flexibility Service rewards households and businesses for shifting peak-time electricity use, enhancing grid balancing, energy security, and net zero goals with ESO and Ofgem support, virtual power plants, and 2GW capacity this winter.

 

Key Points

A grid program paying homes and businesses to shift peak demand, boosting energy security and lowering winter costs.

✅ Pays £3,000/MWh for reduced peak-time usage

✅ Targets at least 2GW via virtual power plants

✅ Rolled out by suppliers with Ofgem and ESO

 

This month we published our analysis of the British electricity system this winter. Our message is clear: in the base case our analysis indicates that supply margins are expected to be adequate, however this winter will undoubtedly be challenging, with high winter energy costs adding pressure. Therefore, all of us in the electricity system operator (ESO) are working round the clock to manage the system, ensure the flow of energy and do our bit to keep costs down for consumers.

One of the tools we have developed is the demand flexibility service, designed to complement efforts to end the link between gas and electricity prices and reduce bills. From November, this new capability will reward homes and businesses for shifting their electricity consumption at peak times. And we are working with the government, businesses and energy providers to encourage as high a level of take-up as possible. We are confident this innovative approach can provide at least 2 gigawatts of power – about a million homes’ worth.

What began as an initiative to help achieve net zero and keep costs down is also proving to be an important tool in ensuring Britain’s energy security, alongside the Energy Security Bill progressing into law.

We are particularly keen to get businesses involved right across Britain. When the Guardian first reported on this service we had calls from businesses ranging from multinationals to an owner of a fish and chip shop asking how they could do their bit and get signed up.

We can now confirm our proposals for how much people and businesses can be paid for shifting their electricity use outside peak times. We anticipate paying a rate of £3,000 per megawatt hour, reflecting the dynamics of UK natural gas and electricity markets today. Businesses and homes can become virtual power plants and, crucially, get paid like one too. For a consumer that could mean a typical household could save approximately £100, and industrial and commercial businesses with larger energy usage could save multiples of this.

We are working with Ofgem to get this scheme launched in November and for it to be rolled out through energy suppliers. If you are interested in participating, or understanding what you could get paid, please contact your energy supplier.

Innovations such as these have never mattered more. Vladimir Putin’s unlawful aggression means we are facing unprecedented energy market volatility, across the continent where Europe’s worst energy nightmare is becoming reality, and pressures on energy supplies this winter.

As a result of Russia’s war in Ukraine, European gas is scarce and prices are high, prompting Europe to weigh emergency measures to limit electricity prices amid the crisis. Alongside this, France’s nuclear fleet has experienced a higher number of outages than expected. Energy shortages in Europe could have knock-on implications for energy supply in Britain.

We have put in place additional contingency arrangements for this winter. For example, the ability to call on generators to fire-up emergency coal units, even as the crisis is a wake-up call to ditch fossil fuels for many, giving Britain 2GW of additional capacity.

We need to be clear, it is possible that without these measures supply could be interrupted for some customers for limited periods of time. This could eventually force us to initiate a temporary rota of planned electricity outages, meaning that some customers could be without power for up to three hours at a time through a process called the electricity supply emergency code (ESEC).

Under the ESEC process we would advise the public the day before any disconnections. We are working with government and industry on planning for this so that the message can be spread across all communities as quickly and accurately as possible. This would include press conferences, social media campaigns, and working with influencers in different communities.

Tackling climate change with machine learning: Covid-19 and the energy transition

Covid-19 Energy Transition and Machine Learning reshape climate change policy, electricity planning, and grid operations, from demand forecasting and decarbonization strategies in Europe to scalable electrification modeling and renewable integration across Africa.

 

Key Points

How the pandemic reshapes energy policy and how ML improves planning, demand forecasts, and grid reliability in Africa.

✅ Pandemic-driven demand shifts strain grid operations and markets

✅ Policy momentum risks rollback; favor future-oriented decarbonization

✅ ML boosts demand prediction, electrification, and grid reliability in Africa

 

The impact of Covid-19 on the energy system was discussed in an online climate change workshop that also considered how machine learning can help electricity planning in Africa.

This year’s International Conference on Learning Representations event included a workshop held by the Climate Change AI group of academics and artificial intelligence industry representatives, which considered how machine learning can help tackle climate change and highlighted advances by European electricity prediction specialists working in this field.

Bjarne Steffen, senior researcher at the energy politics group at ETH Zürich, shared his insights at the workshop on how Covid-19 and the accompanying economic crisis are affecting recently introduced ‘green’ policies. “The crisis hit at a time when energy policies were experiencing increasing momentum towards climate action, especially in Europe, and in proposals to invest in smarter electricity infrastructure for long-term resilience,” said Steffen, who added the coronavirus pandemic has cast into doubt the implementation of such progressive policies.

The academic said there was a risk of overreacting to the public health crisis, as far as progress towards climate change goals was concerned.

 

Lobbying

“Many interest groups from carbon-intensive industries are pushing to remove the emissions trading system and other green policies,” said Steffen. “In cases where those policies are having a serious impact on carbon-emitting industries, governments should offer temporary waivers during this temporary crisis, instead of overhauling the regulatory structure.”

However, the ETH Zürich researcher said any temptation to impose environmental conditions to bail-outs for carbon-intensive industries should be resisted. “While it is tempting to push a green agenda in the relief packages, tying short-term environmental conditions to bail-outs is impractical, given the uncertainty in how long this crisis will last,” he said. “It is better to include provisions that will give more control over future decisions to decarbonize industries, such as the government taking equity shares in companies.”

Steffen shared with pv magazine readers an article published in Joule which can be accessed here, and which articulates his arguments about how Covid-19 could affect the energy transition.

 

Covid-19 in the U.K.

The electricity system in the U.K. is also being affected by Covid-19, even as the U.S. electric grid grapples with climate risks, according to Jack Kelly, founder of London-based, not-for-profit, greenhouse gas emission reduction research laboratory Open Climate Fix.

“The crisis has reduced overall electricity use in the U.K.,” said Kelly. “Residential use has increased but this has not offset reductions in commercial and industrial loads.”

Steve Wallace, a power system manager at British electricity system operator National Grid ESO recently told U.K. broadcaster the BBC electricity demand has fallen 15-20% across the U.K. The National Grid ESO blog has stated the fall-off makes managing grid functions such as voltage regulation more challenging.

Open Climate Fix’s Kelly noted even events such as a nationally-coordinated round of applause for key workers was followed by a dramatic surge in demand, stating: “On April 16, the National Grid saw a nearly 1 GW spike in electricity demand over 10 minutes after everyone finished clapping for healthcare workers and went about the rest of their evenings.”

Climate Change AI workshop panelists also discussed the impact machine learning could have on improving electricity planning in Africa. The Electricity Growth and Use in Developing Economies (e-Guide) initiative funded by fossil fuel philanthropic organization the Rockefeller Foundation aims to use data to improve the planning and operation of electricity systems in developing countries.

E-Guide members Nathan Williams, an assistant professor at the Rochester Institute of Technology (RIT) in New York state, and Simone Fobi, a PhD student at Columbia University in NYC, spoke about their work at the Climate Change AI workshop, which closed on Thursday. Williams emphasized the importance of demand prediction, saying: “Uncertainty around current and future electricity consumption leads to inefficient planning. The weak link for energy planning tools is the poor quality of demand data.”

Fobi said: “We are trying to use machine learning to make use of lower-quality data and still be able to make strong predictions.”

The market maturity of individual solar home systems and PV mini-grids in Africa mean more complex electrification plan modeling is required, similar to integrating AI data centers into Canada's grids at scale.

 

Modeling

“When we are doing [electricity] access planning, we are trying to figure out where the demand will be and how much demand will exist so we can propose the right technology,” added Fobi. “This makes demand estimation crucial to efficient planning.”

Unlike many traditional modeling approaches, machine learning is scalable and transferable. Rochester’s Williams has been using data from nations such as Kenya, which are more advanced in their electrification efforts, to train machine learning models to make predictions to guide electrification efforts in countries which are not as far down the track.

Williams also discussed work being undertaken by e-Guide members at the Colorado School of Mines, which uses nighttime satellite imagery and machine learning to assess the reliability of grid infrastructure in India, where new algorithms to prevent ransomware-induced blackouts are also advancing.

 

Rural power

Another e-Guide project, led by Jay Taneja at the University of Massachusetts, Amherst – and co-funded by the Energy and Economic Growth program on development spending based at Berkeley – uses satellite imagery to identify productive uses of electricity in rural areas by detecting pollution signals from diesel irrigation pumps.

Though good quality data is often not readily available for Africa, Williams added, it does exist.

“We have spent years developing trusting relationships with utilities,” said the RIT academic. “Once our partners realize the value proposition we can offer, they are enthusiastic about sharing their data … We can’t do machine learning without high-quality data and this requires that organizations can effectively collect, organize, store and work with data. Data can transform the electricity sector, as shown by Canadian projects to use AI for energy savings, but capacity building is crucial.”

Updated Germany hydrogen strategy sees heavy reliance on imported fuel

Germany Hydrogen Import Strategy outlines reliance on green hydrogen imports, expanded electrolysis capacity, IPCEI-funded pipelines, and industrial decarbonization for steel and chemicals to reach climate-neutral goals by 2045, meeting 2030 demand of 95-130 TWh.

 

Key Points

A plan to import 50-70% of hydrogen by 2030, backing green hydrogen, electrolysis, pipelines, and decarbonization.

✅ Imports cover 50-70% of 2030 hydrogen demand

✅ 10 GW electrolysis target with state aid and IPCEI

✅ 1,800 km H2 pipelines to link hubs by 2030

 

Germany will have to import up to 70% of its hydrogen demand in the future as Europe's largest economy aims to become climate-neutral by 2045, an updated government strategy published on Wednesday showed.

The German cabinet approved a new hydrogen strategy, setting guidelines for hydrogen production, transport infrastructure and market plans.

Germany is seeking to expand reliance on hydrogen as a future energy source to bolster energy resilience and cut greenhouse emissions for highly polluting industrial sectors that cannot be electrified such as steel and chemicals and cut dependency on imported fossil fuel.

Produced using solar and wind power, green hydrogen is a pillar of Berlin's plan to build a sustainable electric planet and transition away from fossil fuels.

But even with doubling the country's domestic electrolysis capacity target for 2030 to at least 10 gigawatts (GW), Germany will need to import around 50% to 70% of its hydrogen demand, forecast at 95 to 130 TWh in 2030, the strategy showed.

"A domestic supply that fully covers demand does not make economic sense or serve the transformation processes resulting from the energy transition and the broader global energy transition overall," the document said.

The strategy underscores the importance of diversifying future hydrogen sources, including potential partners such as Canada's clean hydrogen sector, but the government is working on a separate strategy for hydrogen imports whose exact date is not clear, a spokesperson for the economy ministry said.

"Instead of relying on domestic potential for the production of green hydrogen, the federal government's strategy is primarily aimed at imports by ship," Simone Peter, the head of Germany's renewable energy association, said.

Under the strategy, state aid is expected to be approved for around 2.5 GW of electrolysis projects in Germany this year and the government will earmark 700 million euros ($775 million) for hydrogen research to optimise production methods, research minister Bettina Stark-Watzinger said.

But Germany's limited renewable energy space will make it heavily dependent on imported hydrogen from emerging export hubs such as Abu Dhabi hydrogen exports gaining scale, experts say.

"Germany is a densely populated country. We simply need space for wind and photovoltaic to be able to produce the hydrogen," Philipp Heilmaier, an energy transition researcher at Germany energy agency, told Reuters.

The strategy allows the usage of hydrogen produced through fossil energy sources preferably if the carbon is split off, but said direct government subsidies would be limited to green hydrogen.

Funds for launching a hydrogen network with more than 1,800 km of pipelines in Germany are expected to flow by 2027/2028 through the bloc's Important Projects of Common European Interest (IPCEI) financing scheme, as the EU plans to double electricity use by 2050 could raise future demand, with the goal of connecting all major generation, import and storage centres to customers by 2030.

Transport Minister Volker Wissing said his ministry was working on plans for a network of hydrogen filling stations and for renewable fuel subsidies.

Environmental groups said the strategy lacked binding sustainability criteria and restriction on using hydrogen for sectors that cannot be electrified instead of using it for private heating or in cars, calling for a plan to eventually phase-out blue hydrogen which is produced from natural gas.

Germany has already signed several hydrogen cooperation agreements with countries such as clean energy partnership with Canada and Norway, United Arab Emirates and Australia.

Japan opens part of last town off-limits since nuclear leaks

Futaba Partial Reopening marks limited access to the Fukushima exclusion zone, highlighting radiation decontamination progress, the train station restart, and regional recovery ahead of the Tokyo Olympics after the 2011 nuclear disaster and evacuation.

 

Key Points

A lift of entry bans in Futaba, signaling Fukushima recovery, decontamination progress, and a train station restart.

✅ Unrestricted access to 2.4 km² around Futaba Station

✅ Symbolic step ahead of Tokyo Olympics torch relay

✅ Decommissioning and decontamination to span decades

 

Japan's government on Wednesday opened part of the last town that had been off-limits due to radiation since the Fukushima nuclear disaster nine years ago, in a symbolic move to show the region's recovery ahead of the Tokyo Olympics, even as grid blackout risks have drawn scrutiny nationwide.

The entire population of 7,000 was forced to evacuate Futaba after three reactors melted down due to damage at the town's nuclear plant caused by a magnitude 9. 0 quake and tsunami March 11, 2011.

The partial lifting of the entry ban comes weeks before the Olympic torch starts from another town in Fukushima, as new energy projects like a large hydrogen system move forward in the prefecture. The torch could also arrive in Futaba, about 4 kilometres (2.4 miles) from the wrecked nuclear plant.

Unrestricted access, however, is only being allowed to a 2.4 square-kilometre (less than 1 square-mile) area near the main Futaba train station, which will reopen later this month to reconnect it with the rest of the region for the first time since the accident. The vast majority of Futaba is restricted to those who get permission for a day visit.

The three reactor meltdowns at the town's Fukushima Dai-ichi nuclear power plant spewed massive amounts of radiation that contaminated the surrounding area and at its peak, forced more than 160,000 people to flee, even as regulators later granted TEPCO restart approval for a separate Niigata plant elsewhere in Japan.

The gate at a checkpoint was opened at midnight Tuesday, and Futaba officials placed a signboard at their new town office, at a time when the shutdown of Germany's last reactors has reshaped energy debates abroad.

“I'm overwhelmed with emotion as we finally bring part of our town operations back to our home town," said Futaba Mayor Shiro Izawa. “I pledge to steadily push forward our recovery and reconstruction."

Town officials say they hope to see Futaba’s former residents return, but prospects are grim because of lingering concern about radiation, and as Germany's nuclear exit underscores shifting policies abroad. Many residents also found new jobs and ties to communities after evacuating, and only about 10% say they plan to return.

Futaba's registered residents already has decreased by 1,000 from its pre-disaster population of 7,000. Many evacuees ended up in Kazo City, north of Tokyo, after long bus trips, various stopovers and stays in shelters at an athletic arena and an abandoned high school. The town's government reopened in a makeshift office in another Fukushima town of Iwaki, while abroad projects like the Bruce reactor refurbishment illustrate long-term nuclear maintenance efforts.

Even after radiation levels declined to safe levels, the region's farming and fishing are hurt by lingering concerns among consumers and retailers. The nuclear plant is being decommission in a process that will take decades, with spent fuel removal delays extending timelines, and it is building temporary storage for massive amounts of debris and soil from ongoing decontamination efforts.

✅ LFP chemistry with UL 9540 and UL 9540A safety compliance

✅ Adds capacity, energy, and ancillary services to CA grid

 

San Diego Gas & Electric Company (SDG&E), a regulated public utility that provides energy service to 3.7 million people, has awarded Mitsubishi Power an order for a 10 megawatt (MW) / 60 megawatt-hour (MWh) energy storage solution for its Pala-Gomez Creek Energy Storage Project in Pala, California. The battery energy storage system (BESS) will add capacity to help meet high energy demand, support grid reliability and operational flexibility, underscoring the broader benefits of energy storage now recognized by utilities, maximize use of renewable energy, and help prevent outages during peak demand.

The BESS project is Mitsubishi Power’s eighth in California, bringing total capacity to 280 MW / 1,140 MWh of storage to help meet California’s clean energy goals with reliable power to complement renewables, alongside emerging solutions like a California green hydrogen microgrid for added resilience.

Mitsubishi Power’s Emerald storage solution for SDG&E includes full turnkey design, engineering, procurement, and construction, as well as a 10-year long-term service agreement, aligning with CEC long-duration storage funding initiatives underway. It is scheduled to be online in early 2023.

The project will repower an existing energy storage site. It will employ Mitsubishi Power’s Emerald Integrated Plant Controller, which is an Energy Management System (EMS) and Supervisory Control and Data Acquisition (SCADA) system with real-time BESS operation and a monitoring/supervisory control platform. Mitsubishi Power leverages its decades of technology monitoring and diagnostics to turn data into actionable insights to maximize reliability, a priority as regions like Ontario increasingly rely on battery storage to meet rising demand. The Mitsubishi Power Emerald Integrated Plant Controller complies with North American Electric Reliability Corporation critical infrastructure protection (NERC CIP) standards and meets the highest security certification in the energy storage industry (IEC/ISA 62443, NIST 800-53) for maximum protection from cybersecurity risks and vulnerabilities.

For added physical safety, Mitsubishi Power’s solution employs lithium iron phosphate (LFP) battery chemistry, aligning with BESS adoption in New York where safety and performance are critical. Compared with other chemistries, LFP provides longer life and superior thermal stability and chemical stability, while meeting UL 9540 and UL 9540A safety standards.

Fernando Valero, Director, Advanced Clean Technology, SDG&E, said, “SDG&E is committed to achieving net-zero greenhouse gas emissions by 2045. We are increasing our portfolio of energy storage assets, including virtual power plant models, to reach this goal. These assets enhance grid reliability and operational flexibility while maximizing our use of abundant renewable energy sources in California.”

Tom Cornell, Senior Vice President, Energy Storage Solutions, Mitsubishi Power Americas, said, “As more and more renewables come online during the energy transition, BESS solutions are essential to support a reliable and stable grid. We look forward to providing SDG&E with our BESS solution to add capacity, energy, and ancillary services to California’s grid. Mitsubishi Power’s Emerald storage solutions are enabling a smarter and more resilient energy future for our customers in California and around the globe, with projects like an energy storage demonstration in India underscoring this momentum.”
