A record amount of solar capacity and energy storage is currently in US transmission interconnection queues, according to a new study from Lawrence Berkeley National Laboratory (Berkeley Lab).

At 462GW, solar accounts for most of the total generator capacity in the queues, which reached a record of more than 755GW and an estimated 200GW of storage capacity at the end of 2020. To put that in perspective, the US had 1,117GW of utility-scale electricity generating capacity in operation last year.

Proposed large-scale electric generation and storage projects must apply for interconnection to the bulk power system via interconnection queues. Berkeley Lab said that while many projects that apply for interconnection are not subsequently built, data from the queues provide a general indicator for mid-term trends in developer interest.
