California must spend a whopping $9.3 billion on power grid upgrades to support its transition to green energy, a policy push that has already brought soaring electricity prices to the Golden State.

The California Independent System Operator, a nonprofit that oversees the state’s electric grid, on Monday identified 46 projects the state must fund to complete its transition to solar and wind energy and support increased use of electric cars and home appliances. Those projects, which include new transmission lines and other grid upgrades, will cost billions of dollars and take years to build, the operator said.

Californians already pay some of the highest electricity bills in the nation, and Democratic governor Gavin Newsom’s “aggressive” approach to “accelerate the state’s transition to clean energy” will likely only increase those bills.
