Ford is jumping into the battery energy storage business, betting that booming demand from data centers and the electric grid can absorb the EV battery capacity it says it’s not using.
To achieve this, Ford plans to repurpose its existing EV battery manufacturing capacity in Glendale, Kentucky, into a dedicated hub for manufacturing battery energy storage systems.

Turning cheap daytime solar into electricity you can actually use at night just got a lot cheaper. A new analysis from energy think tank Ember shows that utility-scale battery storage costs have fallen to $65 per megawatt-hour (MWh) as of October 2025 in markets outside China and the US. At that level, pairing solar with batteries to deliver power when it’s needed is now economically viable.

Electricity demand is surging in Texas, and solar, wind, and battery storage are meeting it.
According to new data from the US Energy Information Administration (EIA), electricity demand across the Texas grid managed by the Electric Reliability Council of Texas (ERCOT) hit record highs in the first nine months of 2025. ERCOT, which supplies power to about 90% of the state, saw demand jump 5% year-over-year to 372 terawatt hours (TWh) – a 23% increase since 2021. No other major US grid has grown faster over the past year.
