SFPUC's role and planned upgrades
The San Francisco Public Utilities Commission operates and maintains the electrical system on Treasure and Yerba Buena islands, even though the infrastructure itself belongs to the Treasure Island Development Authority. The agency has laid out a multi‑year program to swap out aging equipment. As outlined by the San Francisco Public Utilities Commission, crews regularly perform planned work that can require temporary shutdowns, while longer‑term upgrades are installed with the goal of improving reliability.
Recurring outages and local impact
Reporting and public records have tied the island to repeated blackouts, with one local investigation counting more than a hundred outages in recent years and residents describing spoiled food, missed work and unreliable service. The San Francisco Public Press has documented persistent outages even after upgrades, and the San Francisco Standard has pointed to causes that include equipment failure and wildlife strikes.
How to stay informed and safe
City officials urged residents to sign up for AlertSF. Treasure Island residents can text 94130 to 888‑777 or register at AlertSF.org, and are reminded to avoid any downed lines. For emergencies, residents should call 911, and for non‑emergency city services they can call 311. Additional preparedness resources are available from the San Francisco Department of Emergency Management.
