LA100: The Los Angeles 100% Renewable Energy Study

NREL provided rigorous, integrated engineering-economic analysis to the Los Angeles Department of Water and Power (LADWP) through the Los Angeles 100% Renewable Energy Study (LA100).

Results show that meeting LA’s goal of reliable, 100% renewable electricity by 2045—or even 2035—is achievable and will entail rapid deployment of wind, solar, and storage technologies this decade.

At the direction of the Los Angeles City Council, LA embarked on a plan to modernize its electricity system infrastructure—aiming for a 100% renewable energy supply by 2045, along with aggressive electrification targets for buildings and vehicles.

With great ambition comes great need for actionable data and analysis, which NREL provided through LA100.


For LA100, NREL evaluated a range of future scenarios to equip LA decision makers with answers to these questions:

  • As more Angelenos adopt energy technologies like electric vehicles and air conditioning, how might that change total demand for electricity throughout LA?
  • What could LA’s future grid look like? Does reaching 100% mean big changes locally—like building new transmission lines or power plants?
  • How can LA make sure that the new system is reliable under extreme events like fires and heat waves?
  • What about impacts on jobs, the local economy, air quality, public health, and environmental justice?
  • And what might all of this cost?

Final Report

The LA100 study final report is presented as a collection of 12 chapters and an executive summary, each of which is available as an individual download.
