Grid scale energy storage going through the roof at PJM, California and Texas markets.

Even though solar continues to dominate, looking at the latest MISO interconnection queue after the end of queue application submission in the 2021 cycle, energy storage is a clear winner.
While PJM's active storage requests more than doubled in 2021 compared to 2020, CAISO's storage quadrupled. These statistics show that FERC Order 841 on energy storage has the intended impact on the transmission grid.
Another key observation that is especially true for the Texas grid operator ERCOT (which does not fall under FERC) is that stand-alone storage is more than 60% of the active requests. If we include solar+storage, then the % jumps to 94%, which shows solar+storage is the popular combination right now with the renewable developer community.
In conclusion, FERC order 841 on electric storage resources provides a clear signal for asset owners to interconnect energy storage.
