The risk that demand for electricity in the UK will exceed supply, leading to power outages this winter, is the lowest since winter 2019/20.The National Energy System Operator’s (NESO) Winter Outlook 2025/26 predicts a reduced base case margin of 6.1 GW, representing 10% of average peak demand during cold spells. It is slightly lower than the projection published in the Early view of winter in July.Last year the margin was 5.2 GW. According to NESO, this year’s larger reduced margin results from the increased storage capacity of battery energy at both the transmission and distribution levels, an increase in gas-fired…
Researchers in China have built an off-grid, fast-cycling, sorption-based atmospheric water capture system. The system is powered by three PV modules and has been tested with four condensation methods, both indoors and outdoors. October 9, 2025 Lior Kahana A group of scientists from China’s Yunnan Normal University and Yunnan Provincial University have developed a PV-powered fast-cycling sorption-based atmospheric water harvesting (SAWH) system. “To increase the usability and scalability of our previous system, an innovative photovoltaic (PV) powered fast cycling SAWH system is proposed for sustainable off-grid water harvesting,” the group explains. “A PV energy supply system is designed to meet…
The US-based generator company has released its PWRmicro microinverter, which integrates with the company’s energy storage, generator and power management system to provide a ‘parallel backup’ solution. October 9, 2025 John Fitzgerald Weaver By pv magazine USA Generac is expanding its solar-plus-storage ecosystem with the launch of the PWRmicro microinverter. Each unit provides up to 820W of AC power and supports up to two 500W solar panels. It comes with a 25-year warranty, including five years of labor coverage for replacement. The PWRmicro is available in both 240 V and 208 V configurations. PWRmicro strings are fed into the Generac…
Mauritania has signed its first independent power producer contract, covering a 60 MW solar-wind hybrid project. Niger has signed a financing deal with the African Development Bank, which plans to develop 240 MW of solar energy by the end of the decade. October 8, 2025 Patrick Jowett Mauritania has signed a $300 million deal with Dubai-based developer Iwa Green Energy for a 60 MW hybrid solar-wind power plant. The deal is the first that Mauritania has signed with an independent energy producer. It is also one of the first projects developed under Desert to Power’s (DtP) Independent Power Producer Joint…
In the first nine months of 2025, Brazil added 1,718 GW of utility-scale solar generation capacity to its electricity matrix, compared to 4 GW in the same period in 2024. October 8, 2025 Livia Neves By pv magazine Brazil By September 2025, 935 MW of utility-scale photovoltaic capacity had come online in Brazil. From January to the end of September, newly connected large-scale solar power plants reached 1,718 GW of new capacity, compared to 4,050 GW in the same period in 2024. The National Electric Energy Agency (Aneel) expects “centralized” solar to add a total of 3,493 GW by 2025,…
The Dept. of Energy is circulating a new list of energy project cancellations just a week after it announced plans to cancel more than 300 subsidies in just the states that voted for Kamala Harris in the 2024 presidential election. The new list, obtained by E&E newsalso includes projects in red states. The more than 600 projects on the list include previously announced terminations. These cuts could impact a number of solar energy initiatives. A A $1.5 million grant on the list awarded to Amicus, O&M Cooperative helped the company create a comprehensive solar O&M training and certification program with…
According to an announcement by the Hong Kong Stock Exchange on October 5, Sungrow Power Supply has officially submitted its application for listing on the mainboard, with China International Capital Corporation (CICC) serving as the sole sponsor. The Chinese inverter and battery storage giant – valued at more than $46 billion – plans to issue 338 million shares and raise around HK$987 million ($126.7 million). Proceeds will be spent on the R&D of next-generation photovoltaic and energy storage products, the construction of overseas manufacturing bases, digital transformation initiatives and the further development of core technologies, especially in network-scale energy storage.…
Policy incentives and hybrid solar-plus-storage projects are accelerating India’s energy storage sector, despite a slowdown in installations in the first half of the year. October 8, 2025 Uma Gupta By ESS news According to Mercom India’s “India’s Energy Storage Landscape 1H 2025 Report,” India’s energy storage capacity reached 490 MWh at the end of June. Karnataka accounted for 33% of the national capacity, Chhattisgarh 24% and Gujarat 16%. Solar-plus-storage systems represented nearly 56% of cumulative installed capacity. Solar and wind energy projects with 24-hour capacity contributed more than 32%, while standalone battery energy storage systems accounted for more than 12%.…
A team of researchers led by the University of Sydney has fabricated a three-junction perovskite-perovskite-silicon tandem solar cell that achieved an energy conversion efficiency of up to 27.06% and set new standards for thermal stability. October 8, 2025 David Caroll By pv magazine Australia Researchers from the University of Sydney have developed the largest and most efficient three-junction perovskite-perovskite-silicon tandem solar cell to date, achieving a record-breaking efficiency of 23.3% on a device with an aperture area of 16 cm2. The research team, led by University of SydneyAdjunct Professor Anita Ho-Baillie said that at a size of 1 cm2, the…
Renewables overtake coal, but growth slows: reports Solar and wind farms generated more electricity than coal this year for the first time ever, but U.S. and Chinese policy shifts are slowing growth, putting a global 2030 target out of reach, reports said Tuesday. The increase in renewable energy use marks a milestone in efforts to shift away from fossil fuels, which are responsible for the majority of greenhouse gas emissions that cause climate change. According to Ember, an energy think tank, the share of renewables in global electricity production rose to 34.3 percent in the first half of the year,…
