California hits stunning new solar and battery records in postcard from energy future

The records on renewable and battery storage continue to tumble in the northern spring as the technologies plays an increasingly important role in two of the biggest state grids in the world – California and Texas.

In California, as Renew Economy has reported over the last week, battery storage has emerged as often the biggest supplier of power for multiple hours in the state’s evening peak, meeting as much as 27 per cent of demand from its fleet of more than 10,000 MW of big batteries.

On Tuesday, California time, battery output jumped about 7,000 MW for the first time, reaching a peak of 7,046 MW at 7.55pm local time, nearly 300 MW above the peak set just a day earlier, and more than 1GW above the record that stood just two weeks earlier.

In Texas, battery capacity is also setting new benchmarks, reaching above 2,000 MW for just the second time ever and for the first time this summer. That share will grow dramatically with another 5 GW of battery capacity being added to the grid this year.

Solar records are also tumbling in quick fashion on both grids, underlying the need for battery storage as the solar output ramps down leading into the evening peaks in both states.

In California, a new peak of 18.54 GW of solar was reached at 1.10pm on Thursday, when battery storage was soaking up 4.4 GW of this output. It was the third time the solar output record had occurred in the last week.

Over the past two months, the share of wind, water and solar has imposed itself on the grid, reaching more than 100 per cent of demand on the last 19 consecutive days, sometimes for nine hours or more, and for 48 out of the last 56 days.

In Texas, a new record for solar also occurred last month when it reached 18.8 GW. This week, the PJM grid in the mid-west of the US set a new solar output record of 7.05 GW, the first time it reached above 7GW, and nearly double its record output from a year ago.
