PUC updates LED streetlight pilot, recommends standard portfolio and limits on metal halide
Summary
Staff told the commission that newer LED fixtures can cut streetlight energy use significantly and recommended setting citywide efficiency standards, limiting fixture styles to reduce maintenance overhead and banning metal halide in new developments; a 50‑fixture Tenderloin deployment is planned for January.
The San Francisco Public Utilities Commission heard a staff presentation on LED streetlights and preliminary deployment plans, with a recommendation to create a limited portfolio of preapproved poles and fixtures and to ban metal halide lamps for new developments.
Sue Black, manager in the Power enterprise, told commissioners the city maintains about 42,000 streetlights (23,000 PUC‑owned, 19,000 owned by PG&E) and that LED technology could provide energy savings of roughly 30–50% compared with existing high‑pressure sodium fixtures while improving color rendering and night‑time visibility. Black described pilot installations at Fulton Street (Civic Center), Beale Street (Market–Mission), and multiple locations in the Sunset District and said early resident responses were largely positive.
Staff recommended the commission support work with the Board of Supervisors and mayor’s office to establish new minimum streetlight energy efficiency and rated‑life standards and to adopt a limited portfolio of poles and fixture styles for new projects. The memorandum provided to the commission reviews prior policy allowing metal halide fixtures only when architectural or landscape design merits the trade‑off; staff said the emergence of white‑light LEDs reduces that rationale and urged limiting metal halide use going forward.
Black said the PUC plans to replace 50 high‑pressure sodium fixtures in the Tenderloin with next‑generation LED fixtures in January, a deployment expected to take about two weeks and funded from existing capital in the near term; staff also said a broader Tenderloin rollout had been proposed for stimulus funding. Commissioners asked staff to include projected payback numbers and an explicit budget line in upcoming budget materials; staff agreed to provide payback and life‑cycle comparisons for further review.
Commissioners raised additional points about historic and architecturally sensitive fixtures (which may require more complex retrofits), how to stage rollout to avoid mixed lighting on the same block, and an exemption process for culturally‑sensitive or historic lighting districts. The commission did not take a formal vote on LED policy at the meeting but directed staff to return with proposed resolutions and implementation steps.
