*Note: In earlier years the in-state coal number included coal-fired power plants owned by California utilities located out-of-state.

  1. In-state generation: Reported generation from units 1 MW and larger.
  2. Net electricity imports are based on metered power flows between California and out-of-state balancing authorities.
    The resource mix is based on utility power source disclosure claims, contract information, and calculated estimates on the remaining balance of net imports.
