The U.S. Department of Energy’s Lawrence Berkeley National Laboratory’s Electricity Markets and Policy group has released their annual power grid queue update.

The report says solar plus energy storage is dominating the country’s power grid queues, representing the majority of new power plant applications.

The queue holds over 1-TWac of generation capacity.

This year, the new capacity added to the queue exceeds 600 GWac and comes from more than 3,000 unique projects.

Solar photovoltaics in the queue total 676-GWac/~845-GWdc of capacity at the end of 2021.

85% of the new capacity came from solar plus energy storage facilities.

Solar coupled with energy storage now totals more than 285-GWac of capacity in the queue.

In total, there is more than 400-GW of energy storage capacity in the queue.
