Envision Group has finished integrating an artificial intelligence management system into the 12.8 GWh battery storage network it operates in northern China, according to CleanTechnica.

The cluster was activated with 12.8 GWh of capacity and is described as the world's largest, CleanTechnica reported. The network was brought online in February, and the final stages of the AI management layer have now been completed, according to the same report.

Within the cluster, the current flagship plant accounts for 4 GWh of capacity, CleanTechnica said. That single site therefore represents just under a third of the aggregate capacity Envision has assembled at the location.

The AI system sits across the storage network rather than a single asset, per CleanTechnica's account of the integration work.

Brazilian manufacturers and solution providers booked 504 MWh of new storage orders in Q1 2026, lifting the cumulative volume of battery systems sold or contracted in the country to roughly 1.9 GWh, ESS News reported.

That quarterly figure follows orders of 730 MWh in 2025, a volume ESS News described as similar to the total accumulated over the previous five years combined. UCB Power says the market is shifting from pilot projects toward commercial-scale deployments.

Contracted volume is running well ahead of what is on the ground. Greener put Brazil's installed battery storage capacity at 852 MWh in its latest public survey, less than half the sold-or-contracted total.

UCB Power raised output of stationary lithium iron phosphate (LFP) batteries from about 47,900 units in 2024 to 53,000 units in 2025, growth of roughly 10%. The chemistry dominates new capacity worldwide: LFP accounted for around 90% of new global battery storage installations in 2025, according to Berná.

Falling equipment costs sit behind the order growth. BloombergNEF data shows the average global price of stationary storage battery packs reached USD 70/kWh in 2025, down about 45% from the previous year.

The decline is visible at system level in Brazil, though at a slower pace. Greener's benchmark price for a 500 kW/1 MWh system fell from around BRL 1.88/Wh in 2025 to BRL 1.73/Wh in 2026.

Battery storage revenues rose in July while long-term renewable power purchase agreements stayed relatively insulated from wholesale swings, Swiss consultancy Pexapark said.

Geopolitical tensions in the Middle East pushed average gas prices about 10% above second-quarter levels, lifting European power prices, according to Pexapark.

The divergence is sharpest in tolling contracts. In Germany, the benchmark price for a seven-year battery tolling agreement with operations starting in 2028 exceeded EUR 102/MW/year at the end of July, Pexapark said, a rise of 5.2% from the level before the latest escalation in the Middle East conflict.

Solar contract pricing shows the same split between short and long tenors. The consultancy put the fair value of a one-year pay-as-produced solar PPA in Germany at EUR 50/MWh in July, up 15.4%, while 10-year contracts gained 3.6% to EUR 36.6/MWh. The gap between the two tenors is the mechanism Pexapark points to: near-term contracts absorb the wholesale move, decade-long deals do not.

Deal flow stayed concentrated in one market. Pexapark tracked 14 PPAs in July, of which 10 were signed in Spain, with an average contract duration of 12 years.

Three of the tracked deals were battery storage PPAs, each running four years, signed in Italy, Denmark and the United States, according to the consultancy. That four-year term sits well below the 12-year average across the wider July sample.

China Green Development Investment Group has started building a 20 MW flywheel energy storage system in Qinghai province, designed to restore grid inertia lost to rising wind and solar penetration, according to ESS News.

The group's Qinghai branch broke ground on August 1 in Golmud, in the Haixi Mongolian and Tibetan autonomous prefecture, ESS News reported. Nine other organizations are involved, among them the China Electric Power Research Institute and Tsinghua University.

The spinning-mass units are one element of the Golmud Dongyue energy storage station. Per ESS News, the site pairs 150 MW/600 MWh of grid-forming lithium iron phosphate battery storage with the 20 MW flywheel installation and a 5 MW supercapacitor system.

That mix splits duties across three response speeds: the LFP block carries bulk energy shifting, while the flywheels and supercapacitors cover the sub-second and short-duration end where synchronous generation once supplied inertia.

Work on the wider Dongyue project started in April 2026, with commissioning scheduled for 2027, ESS News reported.
