- Batteries and storage (per Base Power): 2,500 batteries, about 100 MWh
- Member fee: one-time $95
- First installations: 2027
Central Georgia Electric Membership Corporation (Central Georgia EMC) and Base Power announced a 50 MW residential battery program on Oct. 13, 2026. The batteries will sit at member homes across the cooperative’s 16-county territory between suburban Atlanta and Macon, Georgia. Base Power told pv magazine USA the program will use 2,500 Base Core batteries. That equals about 100 MWh of storage. Members pay a one-time $95 fee. Base plans the first installations for 2027.
The deal is Base Power’s first utility partnership outside Texas, according to the release.
How the Program Works
Base installs and maintains every battery. Base Power keeps ownership of the fleet, EnergyTech reported. The cooperative controls when the fleet charges and discharges, and it can dispatch the networked fleet 24/7.
Central Georgia EMC plans to dispatch the batteries to reduce load during system peaks. It will also charge them when energy prices are low and discharge them when prices are high. A member who hosts a battery gets automatic, whole-home backup with no additional monthly costs. Members pay only for the energy their home uses, at their normal Central Georgia EMC rates.
“We can add flexible local capacity to support our electric system,” said George L. Weaver, President/CEO of Central Georgia EMC. Tim Pianta leads utility partnerships at Base. He told pv magazine USA the Atlanta region “is a great fit for our technology.”
Why It Matters
A small cooperative adds peak capacity at member homes, and it does not own the hardware. Base owns the batteries, and the co-op keeps the dispatch controls. Georgia is also Base’s first market outside Texas. Its existing utility partners are Austin Energy, El Paso Electric, CoServ, Farmers Electric Cooperative and Guadalupe Valley Electric Cooperative.
The deal is Base’s first major expansion since its $1 billion Series D in August. EnergyTech said that round valued the company at $13 billion. Base says its fleet now totals more than 750 megawatt-hours across 30,000+ homes.
What the Announcement Does Not Say
No battery goes in before 2027. The release sizes the program only as 50 MW of residential battery storage. The 2,500-battery and 100 MWh figures come from Base Power through pv magazine USA, not from the release.
The two sources also count the co-op differently. pv magazine USA says Central Georgia EMC serves more than 61,000 residential customers. EnergyTech, citing the co-op, says it serves over 69,000 billed accounts.
The backup promise rests on company claims. Base Power states that one of its batteries can back up a home for up to 36 hours. On most days, though, the fleet works for the grid. pv magazine USA reported that the co-op will dispatch the batteries’ collective capacity to meet its needs for energy and capacity.
Critical Perspective
The release does not say what Central Georgia EMC pays Base for 50 MW of dispatch rights. Members have no price to set against a utility-scale battery. The figures also limit the backup promise. About 100 MWh across 2,500 batteries is roughly 40 kWh per home. That is the size of one 39.2 kWh Base Core unit, which Base rates for up to 36 hours of backup. A battery the co-op has just discharged at a summer peak holds less when a storm arrives. In March, MGRID covered the 100 MW CoServ program in North Texas. That release also gave no home count and no system size. Who decides how much charge stays in reserve for the member?
