DOE Releases GATEWAY Report on San Francisco Street Lighting Demonstration

January 30, 2009

The U.S. Department of Energy (DOE) has published the report from a San Francisco, California, demonstration of LED street lighting. This GATEWAY demonstration report, prepared by Pacific Gas & Electric and Energy Solutions, provides an overview of project results including lighting performance, cost effectiveness, and potential energy savings.

In this project, four manufacturers' LED street lights were installed on four public avenues in the Sunset District of San Francisco, each with a total of five street lights from the beginning to end of the block. On each avenue, 100-watt nominal high-pressure sodium (HPS) luminaires were replaced with new LED luminaires (each street featuring a different LED product).

Key findings are:

  • While lighting performance varied among the LED luminaires assessed in this study, energy savings potential was high in each case, with energy reductions ranging from 50% to 70% over the current HPS system.
  • The products that generally performed better in terms of lighting performance also proved to be more economically attractive.
