Solar and wind curtailment have increased by 29% between 2023 and 2024 in California, according to the US Energy Information Administration.

The California Independent System Operator (CAISO) has taken control of a 500kV, 125-mile transmission line between California and Arizona.

The Turlock Irrigation District (TID) has launched a request for proposals to add renewable power projects to its portfolio.

With more than 1TW of solar waiting for grid connection, PV Tech Premium looks at where the PV capacity is queued up in the US.

Solar curtailments in California, the US, have never been higher in 2023, as solar generation outpaces transmission capacity upgrades, according to a report from the US Energy Information Administration (EIA).

California Independent System Operator (CAISO) has approved a transmission plan consisting of 45 projects for system expansion and upgrades with a cost of US$7.3 billion, including a total of more than 17GW of solar generation.

The plan also outlined some transmission projects to integrate the generation and storage resources, with the estimated cost of up to US$2.3 billion.

A 500kV, 125-mile transmission line between California and Arizona broke ground last week, promising to bring over 3GW of renewable energy capacity to the US Desert Southwest region.

The intense wildfires that ravaged California in the US in 2020 have been responsible for substantial solar energy forecasts errors, according to a study led by scientists at the National Center for Atmospheric Research (NCAR).

California’s grid operator has green-lighted a new plan to upgrade and expand the state’s transmission system as more renewables come online amid increased electrification.
