Total California solar output hit a new record this week, placing sun-driven generation at the top of the overall California generation mix so far this month. California solar photovoltaic generation hit a new record Thursday at about 100.2 GWh/d, according to Cal-ISO data, breaking the previous solar PV record of 100.1 GWh/d set May 7. Solar PV and solar thermal combined were about 105.5 GWh/d Thursday, also the highest total for solar output in the ISO’s footprint. If solar remains strong for the rest of May, it could become the top generation source in the overall fuel mix for the state, right behind imported power. In the past, thermal generation — comprising mainly natural gas-fired generation — typically topped the overall fuel mix. In some spring months, hydro generation can sit atop the overall generation mix as winter precipitation comes off the mountains. California imports so far this month […]
