Two large-scale battery energy storage systems providing a total of 20 MW of power and 80 MWh of storage are now online along the eastern coast of Virginia. Funded by Climate First Bank and developed by Patterson Enterprises in partnership with battery manufacturer Great Power, the investment will increase the resilience of the region’s electricity grid and community sustainability in the towns of Exmore and Tasley. The LiFePO4 BESS projects support Virginia’s Clean Economy Act goal of 100% clean energy by 2050 and generate money through energy arbitrage, storing electricity when supply is plentiful and releasing it during peak demand.…
Germany’s battery storage boom is real, but so are its bottlenecks. With capital flowing in and gigawatt-hour-scale projects nearing launch, grid connection delays and regulatory uncertainty threaten to dampen momentum. At the third BVES Investor Summit in Berlin, more than 500 industry leaders gathered to weigh the hype against the harsh reality. October 22, 2025 Marija Maisch By ESS news The hype surrounding the German battery storage market continues to grow, but so do the challenges, especially around grid connections. While operating assets are delivering almost unbelievably strong returns and the first gigawatt-hour scale projects are on the horizon, the…
Storage is essential to increase the penetration of renewable energy sources and ensure the flexibility of the electricity grid, according to a study by consultant PSR. However, regulatory and tax barriers still limit the sector and new sources of revenue are needed to make projects viable. October 22, 2025 Livia Neves By ESS news The adoption of energy storage technologies, such as lithium-ion batteries and hydroelectric power plants, could reduce the average cost of Brazil’s electricity system by as much as 16% by 2029, in addition to contributing to reliability and enabling a greater share of renewable energy sources without…
Standard Solar announced it has completed a new community solar and storage project in Westport, Massachusetts. The Division Road project, a 2.38 MW ground-mounted solar array paired with 999 kW DC-coupled battery storage, is now delivering clean power to the New England electric grid. The project was taken over from New Leaf Energy and built in collaboration with EDF power solutions. With nearly 1 MW of storage integrated into the design, the project adds flexibility and resilience to the regional grid, ensuring clean energy is available when demand is greatest. The project also contributes to the state’s Solar Massachusetts Renewable…
Gore Street Energy Storage Fund (GSF) has appointed Norman Crighton as non-executive director of the company, among other changes to the composition of its board of directors and the appointment of Alexa Capital as sell-side advisor.Alexa Capital will advise GSF on the sales process for its 22MW/28MWh Cremzow battery energy storage system (BESS) in Germany, in which the company acquired a 90% stake in 2022.The firm will also advise on the sale of other, as yet undisclosed, pre-construction assets in GSF’s portfolio.GSF announced further changes to its board, with Norman Crighton appointed as the company’s new non-executive director and joining…
Statistics from Enedis show that in the period January-September, 4.2 GW of solar energy was connected to the French electricity grid, including 82 MW combined with storage, which represents a slight decrease compared to 2024. October 22, 2025 Gwénaëlle Deboutte By pv magazine France French distribution network operator Enedis reported 1,507 MW of new PV capacity connected to the electricity grid in the third quarter of 2025, of which 82 MW was equipped with storage. Combined with 1,407 MW connected in the first quarter and 1,358 MW in the second, total new capacity reached 4,272 MW in the first nine…
On October 21, Vote Solar and Sierra Club filed Request for reconsideration with the Idaho Public Utilities Commission (PUC) following Idaho Power’s partially approved proposal to reduce offset rates for customer-generated solar. In this petition, the organizations asked the committee to establish a working group to resolve issues with rooftop solar export tariffs before the next scheduled review in 2028. In the final orderthe PUC allowed Idaho Power to reduce its solar export rate by 31%, down from the original 60% the utility requested, and froze further changes until 2028. This decision affects more than 14,000 Idaho households that installed…
Metals and energy production company Metlen has signed a power purchase agreement (PPA) with French energy company Engie for solar energy in Britain. Under the ten-year agreement, Metlen Engie will supply 235 MW of solar energy annually, generated from six solar projects in the UK. The projects were all developed and built by M Renewables, Metlen’s solar project engineering and construction division. Four locations are expected to be operational by the end of 2025, the company said, while the last two are planned for 2026. Metlen said it has 90 renewable energy projects in the UK, including solar and battery…
In the last monthly magazine for pv magazinethe International Solar Energy Society (ISES) explains how pumped hydro storage combined with PV energy generation can power data centers 24/7 October 22, 2025 International Solar Energy Association (ISES) Pumped Hydro Energy Storage (PHES) offers a widely available, highly mature, cheapest, lowest impact and longest lifespan solution for dunkelflaute. PHES represents 95% of global energy storage. The world has 820,000 PHES sites with a combined storage of 86 million GWh, equivalent to the usable storage in 2,000,000,000,000 electric vehicle batteries. PHES and batteries are a complete energy storage solution for solar and wind…
Machine learning and solar energy come together for sustainable soil remediation Soil pollution continues to endanger ecosystems, agriculture and human health worldwide. Traditional cleaning methods, while effective, remain energy-intensive and low-carbon, making long-term sustainability difficult to achieve. Researchers have now developed a photovoltaic thermo-electro dual module system (PTEDMS) that combines solar energy, electrical resistance heating (ERH), electrokinetic transport and thermal storage into one self-optimizing platform. The system uses machine learning to dynamically distribute solar energy between electrical and thermal processes, maintaining stable pollutant removal even under fluctuating sunlight. This integration accelerates the breakdown of organic pollutants, reduces energy consumption and…
