Georgia Power’s 128 MW Robins battery enters commercial operation beside Robins Solar.

Georgia Power announced that the Robins Battery Facility — a four-hour 128-megawatt battery energy storage system with about 512 megawatt-hours of energy — has entered commercial operation near Warner Robins, Georgia, Solar Power World reported on 15 September 2026, citing a Georgia Power news item. The system sits on Robins Air Force Base and is paired with the nearby Robins Solar Facility to strengthen energy resilience inside Georgia Power’s utility territory, the outlet says.

The mechanism is co-located storage and solar. Rick Anderson, senior vice president and senior production officer for Georgia Power, said in the Solar Power World write-up that pairing battery storage with solar generation creates a more flexible grid that can respond during peak demand while supporting state growth. Burns & McDonnell served as the engineering, procurement and construction contractor and delivered the project on schedule, according to that report.

The Robins battery is one of four battery energy storage projects Georgia Power is developing. Solar Power World says the utility has already completed battery storage facilities in Cherokee and Lowndes counties totaling 579.5 megawatts and is nearing completion of a 57.5-megawatt facility in Floyd County. Soft FLAG: those sister-project megawatt totals are Solar Power World’s citation of Georgia Power; the desk does not re-audit them.

Ceremony / ribbon colour in the same Solar Power World item names attendees including Bowen Shoemaker (Georgia Power region executive), Macon-Bibb County Mayor Lester Miller, state legislators, Rick Anderson, Colonel Johari Hemphill of Robins Air Force Base, and Central Georgia Joint Development Authority Chairman James Vaughn — listed for attribution, not as a claim that the base owns the battery.

An EveryTicker aggregator post dated 15 September 2026 restates the 128-megawatt commercial-operation announcement and places the facility near Warner Robins in Macon-Bibb County adjacent to the existing solar plant. Soft FLAG: EveryTicker asserts commercial operation “on September 15, 2026”; Solar Power World’s opened item says the system “was recently completed” / “enter commercial operation” without an independent COD clock stamp beyond the 15 September news date. The desk treats 15 September as the announcement date of commercial operation and does not invent a separate COD hour.

Soft FLAG on “news item from Georgia Power”: Solar Power World’s byline attributes the piece to Georgia Power material; the desk did not open a separate georgiaPower.com URL in this pass — load-bearing facts (128 MW, four-hour / 512 MWh pairing, Burns & McDonnell on-schedule EPC, sister Cherokee/Lowndes 579.5 MW and Floyd 57.5 MW nearing completion, Anderson quote, AFB-adjacent siting) are taken from that opened Solar Power World page only.

The pairing logic, as Anderson states it in that write-up, is operational rather than decorative: storage responds during peak demand while solar supplies the daytime resource, and the utility presents the combination as part of a multi-county battery buildout already partly complete. The desk does not invent dispatch economics or capacity-factor numbers beyond those named figures.

What to watch without mood: Floyd County 57.5 MW completion notice; any Georgia Public Service Commission Integrated Resource Plan updates that restate the four-project battery slate; Robins Solar output and battery dispatch figures if Georgia Power publishes them.

Floor: Robins BESS — 128 MW / ~512 MWh, four-hour, Burns & McDonnell EPC — commercial operation announced 15 Sep; paired with Robins Solar on AFB-adjacent site.
