Energy Storage

Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE) has developed a new way to quantify PV self-consumption in Germany using national register and grid-operator data, amid a steady rise in onsite use as installations and storage capacity expand.

UK energy regulator green-lights transmission network operator budgets for five-year period. Initial budget of GBP 10.3 billion ($13.7 billion) approved with an upper-bound estimate of GBP 70 billion transmission investment by 2031. At least GBP 44 billion of transmission spend has already been committed, according to the regulator.

SMA Solar Technology announces the commercialization in Europe of its new MVPS-9200 medium voltage station in a 12-meter containerized version for battery energy storage systems (BESS) and large-scale photovoltaic power plants.

State-owned generator Stanwell and Quinbrook Infrastructure Partners signed memorandums of understanding to deliver a 780 MW / 6,240 MWh CATL battery energy storage system integrated with 1,080 MW of gas turbines at the Gladstone State Development Area in Queensland, Australia.

EcoFlow, Tibber, and Fenecon have introduced new software and hardware updates to improve residential battery control, interoperability, and grid arbitrage across Europe.

Solar and storage industry leaders from China and Europe gathered in Germany this week to advance cross-border partnerships, launch a bilateral storage collaboration platform, and coordinate strategies for scaling PV and battery deployment amid surging demand, grid pressures, and intensifying market competition.

Italy’s PV industry raised concerns over new regulatory measures and funding cuts as Gestore dei servizi energetici (GSE) published results of the FER X auction showing significant price reductions and strong participation in Sicily.

Researchers in China developed a new compressed air energy storage system that uses flooded roadways in abandoned coal mines to store compressed air and heat for nighttime power generation. Simulations show the design can achieve 71.5% thermal efficiency, stable performance, and higher energy density at greater depths, with minimal long-term impact from air leakage.

The US Energy Information Administration (EIA) says that battery storage capacity grew by 13,809 MW in the past 12 months and is projected to expand by another 22,053 MW as solar continues to dominate new utility-scale additions.

Huawei’s FusionSolar 9.0 is a new integrated solar-plus-storage platform featuring smart inverters, AI-driven management, and grid-forming capabilities to turn solar plants into active grid-support assets. It boosts efficiency, reduces costs, and enhances stability in weak grids with high renewable penetration, according to the company.
