As global electricity systems grow increasingly dependent on renewable energy, precision in managing energy storage assets has become a decisive factor in grid stability and project profitability. Wärtsilä’s new GEMS Pulse platform directly addresses this operational challenge by transforming raw battery data into actionable intelligence—aiming to unlock the full financial and technical potential of energy storage systems.

Spain-based renewable energy developer Iberdrola has acquired the proposed 270 MW / 1,080 MWh Tungkillo Battery Energy Storage System (BESS) in South Australia for $492 million from UK-headquartered clean energy firm RES Australia.

Despite record renewable capacity additions of 582 GW in 2024, the world must nearly double its annual deployment rate to 1,122 GW—a 93% increase—to meet the COP28 target of tripling renewable capacity to 11.2 TW by 2030.

MIT researchers have achieved a tenfold increase in the energy storage capacity of electron-conducting carbon concrete (ec³), a material capable of turning buildings, bridges, and pavements into functional energy storage units.

Global renewable energy capacity is projected to expand by 4,600 GW by 2030, roughly equivalent to the combined installed capacity of China, the European Union, and Japan, according to the IEA’s Renewables 2025 report.

Portugal’s EDP Renewables is moving to strengthen its foothold in Australia’s energy transition, with 1.7 gigawatts (GW) of new solar and battery capacity approved under the federal Capacity Investment Scheme (CIS) — a key instrument in the country’s effort to stabilize renewable generation while ensuring long-term investor confidence.

GoldenPeaks Capital (GPC) and Huawei Polska have formalized a Memorandum of Understanding (MoU) to deploy 500 MWh of grid-forming battery energy storage systems (BESS) across Europe, signaling a strategic push to bolster grid stability amid rising renewable energy integration.

In addressing the increasing need for efficient energy storage solutions, a recent study introduced an offline lithium-ion battery repair system that employs a dynamic strategy and hybrid topology, aiming to tackle common issues such as battery inconsistency, high costs, and single control methods in lithium battery packs.

India’s installed energy storage capacity stood at 490 megawatt-hours (MWh) by the end of June 2025, according to Mercom India’s latest Energy Storage Landscape 1H 2025 Report, signaling steady but uneven progress toward the country’s renewable integration goals.

As renewable energy penetration rises, balancing intermittent generation with reliable grid services remains a pressing challenge. Subsurface pumped energy storage (SPES) is emerging as a versatile solution, offering kilowatt-to-megawatt-scale power output from a single well while achieving storage densities over 30 times greater than conventional pumped hydro storage.
