Distributed solar and efficiency saves California $2.6 billion on power lines

California’s grid operator has chosen to cancel 20 transmission projects and revise 21 others, as energy efficiency and distributed generation prove their worth.

Last week California’s grid operator signed off on the state’s 2017-2018 Transmission Plan, which approved 17 new transmission projects combined at a cost of nearly $271 million.

This may seem like a large number, however 20 transmission projects were canceled and 21 were revised due to energy efficiency and residential solar power altering local area load forecasts. The projected savings from these changes is approximately $2.6 billion.

The majority of the projects were located in the service area of utility Pacific Gas and Electric (PG&E), while two of the canceled projects were located in San Diego Gas & Electric territory. PG&E recently announced hitting California’s 33% renewable goal in 2017, and including nuclear and hydroelectric power 78.8% of its electricity came from GHG free sources.

In fact, last year California’s three large investor-owned electricity utilities announced that they will reach 50% renewable energy by 2020 – far ahead of the 2030 Renewable Portfolio Standard goal.
