Grid-scale battery systems that store electricity, often paired with solar or wind, to balance supply and demand and support grid reliability.
Data center developers are paying for batteries, substations and transmission upgrades to win local approval, according to Data Center Knowledge. That puts the cost of residents' rate-hike fears in the developer's budget before any site is approved.

A three-month pilot with Quintrace, esVolta and LevelTen Energy shifted 9.2GWh of hourly solar certificates into the hours when Google's demand outran its renewables. The operators kept control of dispatch.

California needs cover for the hours when solar output falls and demand stays high. Arevon's Cormorant project in Daly City answers four of those hours at 250 MW, under contract to MCE, starting in 2027.
Reality
Georgia Power has put its 128 MW Robins battery into commercial operation next to a solar plant. The much larger queue of approved storage behind it sits mostly at existing power plant sites.

The two companies are pairing Toshiba's SCiB lithium titanium oxide cells with DIMAAG's ZettaWatt platform at a continuous 10C rate. No customer, site, capacity or price has been named, and the specs are still in validation.

ONE Nuclear has site control at all three Louisiana sites and a binding letter of intent at the largest of them. It has not yet named a reactor technology for the nuclear campus, or an in-service date for any of the three.

TQ Ventures and Sheryl Sandberg's family office put $4m behind a Munich battery-software spin-off whose 800 customers average 7.5 sites each, and how much of that footprint trades live is not broken out.

Spark Capital led a $120 million Series A at a $1 billion post-money valuation, putting TAR at $880 million before the cash arrived. The round discloses no contracted megawatts and no other investors.
Reality
The Eagle Point equipment financing buys deliveries starting in the second half of 2027, which is the one thing a developer can quote when a hyperscaler asks how soon a campus energizes, though neither the principal nor the rate is public.

A meat plant scrapped tonnes of product on 28 April 2025, then bought 10 MWh of battery. The arithmetic behind that purchase shows how backup is now specified: against annual load, not runtime.
Reality
EDP Renewables North America and Redwood Coast Energy Authority put a 92 MW / 368 MWh battery inside the existing 300 MW Sandrini Solar site in Kern County. The structure matters more than the size.
Reality
Quinbrook closed A$469 million of debt for Stage 3 of its Brendale battery campus in the same week Stage 2 entered commercial operation. The pattern matters more than the megawatts.
Reality
The EIA's first-half list is a solar-and-storage list. The giant wind farms at the top are decade-old projects finally closing out, not a signal about what you can interconnect next.
