From Electric Cars to the Power Grid: How Ford and GM Are Betting on Battery Storage

Tesla deployed 8.8 gigawatt-hours of energy storage products in the first quarter of 2026 — enough to power roughly 250,000 homes for a day. That single-quarter figure matters because Ford and General Motors are now entering the same storage market, after spending most of 2025 taking massive losses on their electric vehicle programs.

The shift is significant. Ford wrote off $19.5 billion and canceled several EV programs in December 2025. GM followed in January 2026 with a 6 billion dollar writedown tied to its own EV pullback. But both companies still own battery factories and equipment. Instead of scrapping those assets, they are now converting them to build stationary batteries for the electrical grid — a market that is growing fast, driven almost entirely by the power demands of artificial intelligence data centers.

Why the Grid Needs Batteries Right Now

The U.S. installed 165 gigawatt-hours of battery storage capacity by the first quarter of 2026, with 137 gigawatt-hours at utility scale — think of this as large installations that feed power back into the grid. A decade ago, this market barely existed. The main reason it is booming now is data center electricity consumption. AI systems — especially large language models and image generators — demand massive amounts of power, and that power consumption can swing wildly from one moment to the next.

Data centers could consume between 9% and 17% of all U.S. electricity by 2030, according to recent forecasts. Those sudden power spikes are hard for the grid to manage. Batteries deployed at data centers can now store enough energy to keep those facilities running for over 100 hours if the power goes down or if renewable energy sources like solar and wind temporarily underperform. For data center operators that have promised customers guaranteed uptime, that kind of backup is not optional.

Ford Moves Fast: From Car Factory to Battery Warehouse

Ford's entry into grid storage happened quickly. The company announced in December 2025 that it would convert underused factory space in Kentucky to make storage batteries. By January 2026, it appointed Lisa Drake as president of a brand new division called Ford Energy. Drake is a manufacturing veteran tasked with scaling a business that did not formally exist a year earlier.

The first major deal came in May 2026. Ford Energy and EDF Power Solutions North America agreed that EDF would buy up to 4 gigawatt-hours of battery systems annually from Ford. The batteries would be built in Ford's existing Kentucky and Michigan plants — facilities that carry the fixed costs of EV production and now need steady work to stay profitable. In practical terms, Ford is using factories that were expensive to build, repurposing them to make a different product for a market with strong demand right now.

The specific design Ford is making is called a DC Block — essentially a container packed with batteries and control systems, optimized to connect directly to the grid without extra power conversion steps. That efficiency gain matters at scale.

GM's Broader Chemistry Strategy

General Motors is taking a slightly different approach. On June 10, 2026, GM announced it is developing batteries specifically for large-scale utility storage, separate from its consumer storage product called PowerBank. The same day, Reuters reported that GM may stop using a particular type of battery chemistry called LFP for future electric cars.

This matters. LFP (lithium iron phosphate) batteries are extremely durable, don't overheat easily, and cost less than other battery types — all things that make them ideal for grid storage, where you want batteries to charge and discharge thousands of times over many years. But LFP batteries don't store as much energy in the same weight as other chemistries, which is a real problem in cars where every pound adds fuel consumption. If GM stops making LFP for cars and focuses on it for grid storage instead, both products fit their chemistry better.

GM is also working with a recycling company called Redwood Materials. A non-binding agreement from July 2025 outlined plans to use domestically made batteries — a move that matters under current U.S. rules about where components must come from to qualify for government support. GM and LG Energy Solution are also jointly developing a higher-energy-density battery for trucks, announced in May 2025, which offers more power per pound than LFP at lower cost than traditional options.

The Scale Question: Tesla's Advantage

Tesla's 8.8 gigawatt-hours deployed in a single quarter puts into perspective what Ford and GM are just beginning. Tesla has been manufacturing and deploying its Megapack battery system for years, building up manufacturing expertise and real-world knowledge of how these systems perform in the field. That operational learning is hard to rush.

However, there is historical precedent here that is worth considering. When cloud companies like Amazon and Google started designing their own networking hardware and storage systems in the early 2010s, conventional wisdom said established suppliers like Cisco and NetApp had insurmountable advantages. Some did. But the newcomers with direct access to large captive customers and manufacturing flexibility moved faster than expected. Ford and GM are not starting from zero — they have existing battery factories, skilled workforces, and proven supply chains. The real question is whether they can develop the software, thermal management, and battery management systems needed to bring a grid storage product to market before the current demand wave settles into the hands of more specialized competitors.

The China Supply Chain Shadow

One constraint that affects all three companies is the source of battery cells. Even as U.S. manufacturers work to domesticate their supply chains, China remains a key source for battery materials and components. This is not new — battery supply chains have relied on China for a decade — but current trade policy makes it more fraught. Both Ford and GM are trying to reduce that exposure through agreements like GM's partnership with Redwood and Ford's use of its own plants. Still, fully domestic battery supply chains from raw materials to finished product remain a goal for the medium term, not something that exists today.

The Real Opportunity — and Real Risk

The grid storage opportunity is genuinely substantial. U.S. installed capacity sits at 165 gigawatt-hours, utility-scale projects are multiplying, and data center operators are signing long-term contracts for grid storage at volumes that would have seemed speculative just a few years ago. Ford and GM are entering a market where demand is clear and measurable — not a speculative bet on future technology adoption.

The harder question is execution. Tesla's quarterly output of 8.8 gigawatt-hours is now the benchmark against which any competitor is measured. Ford's agreement to supply EDF with 4 gigawatt-hours annually is a legitimate foothold; GM's utility-scale program as of June 2026 is still in development. Neither company is positioned to challenge Tesla's dominance in the near term — and neither needs to in order to build profitable businesses that absorb the fixed costs of their battery factories.

The broader context here is that automakers with excess battery manufacturing capacity are finding a concrete, growing market in grid storage. Whether Ford and GM can execute the product development, manufacturing ramp, and supply chain coordination to capture meaningful share remains an open question. But the incentive structure is now clear, the demand signal is loud, and both companies have the foundational assets to try.
