California’s Energy Usage
According to the latest statistics, there are nearly 39 million people in California.
So, just how much power do 39 million people need?
The CEC reports that, in 2023, Californians used 276,213 gigawatt hours of electric power. That’s an enormous demand for electricity – one that will only continue to grow as population increases.
California’s Energy Sources
Currently, California generates 76 percent of the electric power it needs in-state; the remainder is imported from Arizona and Nevada in the Southwest and Oregon and Washington in the Northwest.
Power Transmission and Distribution
In order to get this power from the generators to customers, California relies on 75 transmission and distribution organizations or load serving entities (LSEs), including:
- 48 Publicly Owned Utilities – including Sacramento Municipal Utilities District, Modesto Irrigation District, and the Los Angeles Department of Water and Power
- 6 Investor-Owned Utilities – including Pacific Gas & Electric, Southern California Edison and San Diego Gas & Electric
- 4 Rural Electricity Cooperatives – including Plumas-Sierra Rural Electric Cooperative
- 3 Native American Utilities
- 14 Other Electricity Service Providers
Meeting Current and Future Energy Needs
These utilities and providers, including TANC’s members, obtain electricity from California’s transmission system, a system that is currently overutilized and at risk of not meeting the state’s energy need. For more information on the state of California’s transmission system see -Reports and Studies.
California’s Goal for Renewable Power Supply
To meet our state’s current and future energy needs, California’s utilities and electricity providers must access more electricity sources – particularly renewable sources – which means more transmission lines will be needed in the state. According to the CEC, “inadequate transmission infrastructure” needed to connect remotely-located renewable resources is one of the top five barriers to achieving California’s aggressive RPS requirement to generate 33 percent of its power from renewable sources by 2020.
Planning for the Future
To meet the state’s RPS and greenhouse gas emission reduction goals over the next ten years, the California Public Utilities Commission (CPUC) projects that 11 new transmission lines will be needed at an estimated cost of $16 billion – only three of these lines are currently under development.
The magnitude of the infrastructure California will have to plan, permit, procure, develop and connect with the state’s electricity power grid in the next decade to meet the RPS target of 33 percent is unprecedented. If implementation were to start today, the needed scale of transmission and generation buildout will take at least 14 years to complete.
