The mission of the division is to assess California’s energy systems and trends, providing information for decision-makers and the public that produce policies that balance the need for adequate resources with economic, public health, safety, and environmental goals. The division’s emphasis is to expand staff capabilities in the latest modeling and analytical techniques.

The division is organized into the Supply Analysis Office and the Demand Analysis Office.

The Supply Analysis Office collects data, produces analyses, and provides policy expertise on a range of energy supply issues. Focusing on markets and infrastructure that provide safe and reliable energy to California, the office is composed of engineers, economists, and other scientists experienced in providing a multidisciplinary view of the energy sector. 

The office has four units:

  • Natural Gas Unit– Collects data and provides analysis and modeling of natural gas markets and infrastructure on global, national, and regional levels.
  • Procurement and Modeling Unit– Collects data and provides analysis and modeling of electricity infrastructure at the high-voltage transmission level across the western United States.
  • Distributed Generation Integration Unit– Provides analysis and technical expertise on issues associated with integrating distributed energy resources into California's electric grid at the transmission and distribution levels.
  • Transportation Fuels Data Unit– Collects data and provides analysis of liquid fuels supply across California. The unit focuses on petroleum-based fuels and the markets and infrastructure supporting them.

The Demand Analysis Office provides energy demand forecasts to policy makers and utilities by collecting and analyzing data on electricity peak demand and consumption, natural gas consumption, and transportation fuel use. In developing these forecasts, the office uses projected economic and demographic growth, projected changes in rates and other cost factors, estimated impacts of energy efficiency efforts, and historical weather data. 

Engineers, economists, and statisticians in the office also rely on data collected from surveys to understand how Californians' behavior and use of appliances, business and industrial equipment, and vehicles affect energy demand over time. Other energy agencies use the office’s electricity and natural gas forecasts for planning. The transportation forecasts assess progress toward meeting California's alternative fuel goals. 

The Demand Analysis Office has four units:

  • Demand Forecasting Unit– Runs and maintains various forecasting models used to develop the Energy Commission's electricity and natural gas demand forecasts.
  • Data Collection Unit– Collects data and analyzes electricity and natural gas consumption by residential, commercial, industrial, and agricultural customers in California.
  • Data Analysis and Survey Unit– Oversees surveys conducted to analyze how Californians choose to use energy in their homes and businesses. 
  • Transportation Energy Forecasting Unit– Develops transportation energy demand and price forecasts for petroleum and alternative fuels used by vehicles to carry passengers and freight in California.
