A new report indicates that four-hour duration batteries are more cost-effective than open-cycle gas turbines in 43 surveyed markets. Despite this shift, data center developers continue to purchase available gas turbines to meet urgent power needs.
Why it matters
While batteries offer a cheaper, cleaner alternative for grid stability, developers remain locked into less efficient gas technologies due to long lead times for newer hardware. This trend risks creating long-term reliance on expensive, aging infrastructure to meet the surging demands of AI data centers.
Four-hour battery systems have surpassed open-cycle gas turbines in cost-efficiency across 43 surveyed markets. Meanwhile, solar remains the cheapest form of new power globally, with 168 gigawatts in the U.S. currently utilizing safe-harbor tax provisions.
The players
Wood Mackenzie
This global research and consultancy firm provides data and insights on the energy and natural resources sectors.
The details
Utilities rely on peaking power plants to handle spikes in electricity demand, a role historically dominated by gas turbines. Open-cycle gas turbines require two to four years to procure, while waitlists for more advanced closed-cycle units now extend into the early 2030s.
Timeline
The report on battery and gas turbine costs was published on 2026-10-09.
Solar projects must begin construction or be completed by the end of 2027 to secure specific tax credits.
Waitlists for closed-cycle gas turbines currently stretch into the early 2030s.
Battery costs in the Middle East and Africa are projected to be 33 percent lower than gas peaking by 2035.
The Tech Race
The shift toward battery-based peaking power reflects an ongoing move away from legacy gas-fired generation in favor of modular, scalable storage. This transition mirrors the rapid adoption cycles seen with the One Big Beautiful Bill solar tax credits, which continue to accelerate the displacement of traditional power sources.
As developers prioritize quick access to power, the continued procurement of inefficient gas turbines may lead to higher electricity prices for end users due to operational costs. Conversely, the growth of battery storage could eventually stabilize prices as utilities transition to more efficient, cost-effective peaking technologies.
The takeaway
The move toward battery storage suggests that cleaner, more cost-effective energy is increasingly viable for large-scale infrastructure. Readers should monitor how energy procurement strategies evolve as technology deployment timelines continue to shorten.
