Today, there are select cases in which lithium-ion batteries are competitive with natural-gas peaker plants. However, in a few years, competition will intensify across the country. And with costs only headed downward, GTM Research and Wood Mackenzie believe that batteries overtaking peakers may be a common occurrence in the U.S. in as little as four years.

Over the next 10 years, the U.S. needs to add 20 gigawatts of peaking capacity to its grid. Over half of that capacity will come on-line in the latter part of the decade: 7,440 megawatts between 2018 to 2020 compared to 12,645 megawatts between 2023 and 2027. That gives energy storage more time to build an economic advantage.
According to a new report, by 2022, new natural-gas peakers will regularly compete head to head with energy storage. In ten years, new natural gas peakers may become a rare sight.
