Emeroo battery secures first approval under South Australia clean energy law
Potentia Energy’s 900 MWh Emeroo battery in South Australia is the first battery energy storage system (BESS) approved under the state’s Hydrogen and Renewable Energy Act.
Solar leads as US grid interconnection agreements grow 33%
Interconnection agreements grew 33% year-over-year in 2024 and are sustaining momentum through 2025, said Wood Mackenzie.
How to control frequency fluctuations during PV plant deloading
Researchers in Egypt have developed new control strategies for managing frequency fluctuations during deloading of a photovoltaic plant. The proposed methodology combines a proportional–integral controller along with a rate of change of frequency controller.
Data center firms could buy utilities and add renewables, says trade group exec
Data center firms could purchase electric utilities and add renewable generation in the United States, says Simon Mahan, executive director of the Southern Renewable Energy Association, which represents the wind, solar, storage and transmission sectors.
US transformer supply may fall sharply in 2025, says Wood Mackenzie
Wood Mackenzie says US power transformer supply could fall 30% and distribution transformers 10% in 2025 due to surging demand and limited manufacturing capacity.
Remedies for PV curtailment in Poland
Solar curtailment is on the rise in Poland, with around 600 GWh of PV capacity reduced during the first six months of 2025. The Warsaw-based Institute for Renewable Energy (IEO) suggests one solution is to support the electrification of Poland’s heating sector with the surplus of PV power.
Expansion of PV for self-consumption reduces grid load
Fraunhofer Institute of Optronics, System Engineering and Image Evaluation – Applied System Technology (IOSB-AST) says Germany’s grid load is falling as more PV output is consumed on-site, but notes rising electrification in other sectors could reverse the trend.
LNG, solar collectors improve round-trip efficiency of LAES systems
Scientists simulated several liquid air energy storage systems, comparing round-trip efficiency across configurations that include liquefied natural gas (LNG), solar, and Stirling engines, and further optimized performance using particle swarm methods.
WHES releases new C&I energy storage system
WHES has released a new commercial and industrial (C&I) energy storage system using a 509 kWh battery with power output options from 62.5 kW to 250 kW, and a maximum efficiency of 98.5%.
PV-powered liquid air system yields hydrogen, heating, fresh water
A global scientific team has designed a novel multigeneration system based on renewable energy and liquid air energy storage, then used soft computing techniques to optimize its operation. The optimized levelized costs of hydrogen (LCoH) were $1.52/kg and $5.22/m³.
