Batteries Outperform Gas Plants for Data Center Energy Needs
Researchers argue energy storage offers a cleaner, faster, and more flexible alternative to fossil fuels.
1The Data Center Boom
The rapid expansion of data centers is driving massive demand for new power generation. Currently, U.S. utilities are planning over 60 gigawatts of new gas plants, while 90 gigawatts of behind-the-meter gas generators have been proposed. This reliance on fossil fuels poses significant climate risks and potential long-term financial burdens for consumers.
2Stranded Asset Risks
Building extensive gas infrastructure creates a risk of stranded assets if computing demand fails to materialize or data centers close prematurely. Other utility customers could be forced to cover these costs, leading to economic inefficiency. States are only beginning to address these financial dangers as the AI sector continues its rapid growth.
3Batteries as Strategic Hedge
Batteries offer a modular and flexible alternative to traditional gas plants, acting as a hedge against demand uncertainty. Unlike rigid fossil fuel infrastructure, energy storage can be scaled up or down based on shifting computing loads. This flexibility helps planners avoid overbuilding capacity while effectively managing the massive energy needs of data centers.
4Grid Stability Benefits
Beyond providing power, batteries function as shock absorbers for the electrical grid. They help cushion the system against the fast-changing and intense computing loads characteristic of modern data centers. By reducing the need for costly grid buildouts, energy storage provides a more efficient way to manage increasing electricity demand across the country.
5Proven Deployment Momentum
While lithium-ion batteries cannot provide round-the-clock power, they are already meeting significant portions of data center electricity needs. Unlike experimental technologies like advanced geothermal or next-generation nuclear, batteries demonstrate clear deployment momentum. BloombergNEF forecasts U.S. storage deployment will surpass 11,000 gigawatt-hours by 2036, driven largely by the surging demand from data centers.
6Regulatory Policy Solutions
States can encourage battery adoption through 'bring your own new clean energy' tariff structures. These regulations mandate that data centers procure sufficient carbon-free generation and storage to cover their electricity needs. Jurisdictions like Nevada and Minnesota have already begun implementing these frameworks to align corporate energy procurement with broader state sustainability goals.
7Navigating Restructured Markets
In states with restructured energy markets, regulators have limited authority over independent power producers. However, they can still promote battery development through state-level storage mandates, such as those seen in Illinois, Maryland, and New Jersey. Engaging in collaborative energy planning with regional grid operators remains a critical path forward for these specific jurisdictions.
8Strategic Energy Transition
Transitioning from gas plants to battery storage is essential for sustainable data center growth. By moving away from fossil fuel inertia, developers can lower costs and reduce climate impacts. Policymakers hold the tools to accelerate this shift, ensuring that the infrastructure supporting the AI revolution is both resilient and environmentally responsible for everyone.
