SFPUC and Partners Alerting Treasure Island Residents About Planned Outages This Weekend
Power Improvement Project Managed by Port of Oakland to Result in Separate One-Hour Planned Outages
Posted Date: 8/13/2019 9:45 AM
San Francisco, CA—The San Francisco Public Utilities Commission (SFPUC), the Treasure Island Development Authority (TIDA) and the San Francisco Department of Emergency Management (SFDEM) are notifying residents, businesses, and community organizations about a power improvement project that will result in temporary outages on Treasure and Yerba Buena Islands this weekend.

The Port of Oakland is performing maintenance and improvement work in the vicinity of the transmission cable that supplies power to Treasure and Yerba Buena Islands, requiring a de-energization of this cable. As a result, the island’s distribution system will be powered by the backup on-Island generators on Saturday, August 17.
Transitioning the power grid to and from the generators will require two separate one-hour temporary interruptions of electrical service to Treasure and Yerba Buena Islands between 4 a.m. – 5 a.m. on Saturday, August 17, and again between 12 a.m. – 1 a.m. on Sunday, August 18.
To notify residents and businesses about the outages, TIDA has distributed standard Electrical Service Interruption Notices in four different languages—English, Spanish, Cantonese and Tagalog. In addition, those notices were also sent to the Coast Guard, Treasure Island Job Corps Center, Life Learning Academy, on-Island non-profit organizations and City departments operating on the island.
The otices were sent a total of four times, and bulletins notifying residents about the planned outage were posted at local gathering spots, including the Treasure Island gym, the ShipShape Community Center, the Island Cove Market, and the Treasure Island Child Development Center.
In addition, SFDEM is encouraging residents to sign up for AlertSF by texting 94130 to 888-777. During the power shutdown, the SFPUC and SFDEM will provide communications support and updates on Twitter and other social media channels.
Approximately 2,500 residents and students currently reside on Treasure Island. The SFPUC is responsible for maintaining and operating Treasure and Yerba Buena Islands' power infrastructure. The infrastructure is owned by TIDA, which inherited the system from the Navy.
An extensive redevelopment program is underway on Treasure Island. The program will produce a new neighborhood of 8,000 homes, more than a quarter of which will be offered at below-market rates, extensive open spaces, three hotels, restaurants, retail, and entertainment venues. As part of the redevelopment project, all of the power infrastructure on the island will be replaced.
