AI Customer ServiceFirst, our results suggest to industry and grid planners that the cost-effective duration for storage is closely tied to the grid’s generation mix. Solar-dominant grids tend to need 6-to-8-h storage while wind-dominant grids have a greater need for 10-to-20-h storage.
We find that energy storage mandates largely reduce the variability in electricity prices, especially for the first 20 TWh of mandates (Fig. 6a). In the 1.94 TWh baseline, 82% of the marginal prices are at 0 $/MWh since for large portions of the year the WECC generates more renewable energy than it needs.
Grid-scale battery storage is a mature and fast-growing industry with demand reaching 123 gigawatt-hours last year. There are a total of 5,000 installations across the world. In the first quarter of 2024, more than 200 grid-scale projects entered operation, according to Rho Motion, with the largest a 1.3GWh project in Saudi Arabia.
The total (a), regional (b), hourly (c), and monthly (d) distributions in the mean marginal electricity prices as the amount of mandated long-duration energy storage (in TWh) increases. Increases up to 20 TWh significantly decrease the variability in marginal prices while increases beyond 20 TWh have a lesser effect.
China is likely to be the main winner from the increased use of grid-scale battery energy storage. Chinese battery companies BYD, CATL and EVE Energy are the three largest producers of energy storage batteries, especially the cheaper LFP batteries.
This large variability in marginal price decreases as energy storage is added to the grid since energy storage shifts the costs of generation during periods of peak demand to periods of low demand. For example, with 20 TWh of storage, 99% of marginal prices drop below 130 $/MWh and only 32% of marginal prices are still at 0 $/MWh.
