Georgia Power opens a 530 MW battery near Ball Ground - EIA lists 530 MWh and 1,060 MWh on two 265 MW units, the November pages print no megawatt-hours, and the box is not on a workplace meter

On 6 November 2026 WSB-TV and the Cherokee Tribune described a ribbon at Georgia Power's McGrau Ford battery near Ball Ground, both printing 530 MW. WSB prints 1,100 Tesla units and nine engineers on site. The September 2026 EIA inventory lists two operating units of 265 MW, with 530 MWh and 1,060 MWh, and an operating month of August 2026. A May 2025 Georgia Power page printed later commercial-operation months and a separate 50 MW customer solar-plus-storage pilot. The November pages do not put this battery on a workplace meter.

A factory in Georgia does not take delivery of this battery. Georgia Power cut a ribbon on a grid battery. The box charges and discharges for the utility network. It is not a cabinet on a workplace meter.

WSB-TV, timed 6 November 2026 at 4:05 pm EST, says Georgia Power and local leaders cut the ribbon Friday on a battery facility near Ball Ground in Cherokee County. Friday was 6 November. WSB calls it the fourth and largest battery storage facility in the state. It prints 1,100 self-contained Tesla batteries and a total capacity of 530 megawatts. It says each megawatt is capable of powering 800 to 1,000 homes. That homes line is WSB's. The page does not print a bill, and it does not print megawatt-hours. Nine engineers are stationed on site. A monitoring company in Alabama gets a work ticket if a unit has an issue. Rick Anderson, senior vice president, is quoted on the battery sitting in a mix with nuclear, gas, solar and coal. Solar in that sentence is another source on the system. The page does not say panels stand on this lot.

The Cherokee Tribune, dated 6 November 2026, prints the same 530 megawatts and the street address 1501 Conns Creek Road near Ball Ground. It calls the site Georgia's largest battery energy storage facility and says it is now open. The page's longer paragraphs did not come through as readable text in the copy fetched here, so job counts, a county dollar figure and any battery count beyond the 530 MW stay off this note unless another page prints them. WSB's 1,100 Tesla units are WSB's figure. The Tribune fetch did not confirm that count.

EIA's preliminary monthly generator inventory for September 2026, in the file september_generator2026.xlsx, last modified 23 October 2026, lists plant 68512, McGrau Ford Battery Storage Facility, operator Georgia Power Co, Cherokee County, sector electric utility. Two generators are marked operating. Each is 265 MW. Generator 1's nameplate energy capacity is 530 MWh. Generator 2's is 1,060 MWh. The operating month is August 2026. The status cell reads "(OP) Operating". The technology cell reads "Batteries". The sheet does not name Tesla, does not name a phase, and does not print hours. 265 plus 265 is 530, our arithmetic, the same 530 MW the November pages print. 530 divided by 265 is 2. 1,060 divided by 265 is 4. 530 plus 1,060 is 1,590. Those three results are our arithmetic. The sheet does not print 2 hours, 4 hours or 1,590 MWh. The EIA index page says these capacities are preliminary estimates and are not capacity commitments.

A megawatt is how hard the box can push. A megawatt-hour is how long it can keep pushing. Two hours at 265 MW is a different tank from four hours at 265 MW. The November news pages print the push, 530 MW, and leave the tanks blank.

Georgia Power's release of 7 May 2025 is the construction note, not the ribbon. It prints McGrau Ford Phase I and II as 530 MW in Cherokee County, engineered and built by Burns & McDonnell, with projected commercial operation in October 2026 and September 2026. It says the phases share a project-level substation and a generation tie line, on company-owned land. It does not print megawatt-hours or a dollar build cost. It does not put solar on this site. On the same page, Robins and Moody are the battery projects described as sitting with existing solar. McGrau Ford is not in those sentences.

The same 2025 page says a Customer-Sited Solar Plus Storage Pilot aims to secure an initial 50 MW, for residential and small commercial customers, pairing batteries with solar behind the meter. Behind the meter means on the customer's side of the utility meter, like a cabinet in the building, rather than a box the utility owns down the road. "Aims to secure" is the page's wording. The 6 November ribbon pages do not mention that pilot, do not name a shop, and do not print a customer rate.

The August operating month on the September inventory and the 6 November ribbon are both in print. Neither page explains the gap. The 2025 page's October 2026 and September 2026 projections are a third set of dates. This note does not pick a switch-on day the pages do not share.

Analogy: 530 MW is the width of a fire hose. The EIA lines are two tanks, 530 MWh and 1,060 MWh, on two 265 MW hoses. A workplace battery is a drum in the yard. This one is a utility lot.

Good: Two 6 November pages on a 530 MW ribbon, an EIA sheet with two 265 MW units and two energy figures, and a 2025 company page that keeps solar on other sites and keeps the 50 MW customer pilot in a different sentence.

Bad: No dollar build cost, no cents, no workplace meter, no solar on this lot in the pages read here. 2 hours, 4 hours and 1,590 MWh are our arithmetic. The Tribune's longer body was not readable in the fetch, so this note does not use it for job counts or county dollars. WSB's 800 to 1,000 homes per megawatt is not a factory quote. EIA's figures are preliminary estimates.

Ugly: Treating 530 MW as a battery in a warehouse. Pasting the 50 MW pilot onto the ribbon. Reading WSB's homes line as a bill cut. Adding solar panels the November pages do not put on this site. Adding 1,590 MWh as if EIA printed the sum.

Soft next step: write 530 MW as the utility site, keep 530 MWh and 1,060 MWh as the two EIA lines, and leave the workplace pilot at the 50 MW target on the 2025 page.
