See projection in https://www.canarymedia.com/articles/energy-storage/chart-the-us-grid-battery-fleet-is-about-to-double-again. Also for why this is in Watt not Joules. Will use the same data source for resolution.

With nearly 9.2 gigawatts (GW) of new capacity installed in late November, the year surpassed previous records, per S&P Global data. This highlights the sector’s rapid expansion and future potential.
Power Surge: How Battery Storage Is Transforming the U.S. Grid
Large-scale lithium-ion battery storage installations in the U.S. reached new heights in 2024, surpassing the previous year’s record of 8.4 GW, according to S&P Global data.
By November 25, developers had added 9.2 GW of new capacity, setting a new benchmark for the industry. The third quarter alone accounted for 3.6 GW of these additions, representing a 52.5% increase compared to the same period in 2023. This remarkable growth pushed the nation’s cumulative battery storage capacity to 26.3 GW.
4.8GW more needed in only a little over a month vs rate of installation being ~3.6GW in last quarter so looking like it would need to be a really huge installation total for Dec and last 5 days of Nov to get there.

Could be additions of 14.3GW but this is a forecast for 2024 not actual. Seems dated 20 Dec 2024.
17.3 at end of 2023 + 14.3 additions potentially= 31.6GW but 14.3FW additions forecast might not be met/fully installed by year end and there could be some retired so no longer installed?
Suggests it could be close?
