USA, California:

California Grid Hits Record Solar Generation Peak (KCET)

On June 8, a record 849 MWe of solar-generated electricity was feeding into the state's power grid but on the same day geothermal generated a steady baseload 924 MWe.

Eric Wesoff at GreenTechMedia notes that California reached a renewable energy milestone last week: At one point on June 8, according to the California Independent System Operator (CaISO), a record 849 MWe of solar-generated electricity was feeding into the state's power grid.

According to CaISO's own figures -- which you can track daily here -- the solar contribution has dropped slightly in the last few days, likely a result of slightly lower statewide temperatures reducing peak demand.

A bit of perspective is important here. Even as it was breaking that record on June 8, the state's solar generating capacity wasn't the largest contributor of renewable energy to the grid, according to CaISO. Geothermal plants put a bit over 900 MWe into the grid, and geothermal and solar combined were far outstripped by the state's wind turbines, which generated something in the neighborhood of three gigawatts of power during the course of the day.
