The project is provided in response to both the Seismic Reliability and Delivery Reliability LOS goals. The project provides for standby power at six critical facilities to allow these facilities to remain in operation during power outages and other emergencies.

Description
Standby power requirements are provided at six sites in the East Bay and on the Peninsula. Each site is either provided with an emergency generator or the electrical receptacles to accommodate a portable emergency generator.

The facilities at the six sites include:

• Alameda West Portal: standby power improvements include installing a permanent 20-kilowatt (kW) emergency generator in a sound-attenuated masonry wall enclosure.
• San Antonio Reservoir and Dam: standby power improvements include providing electrical receptacles for a portable 37-kW emergency generator at two locations.
• Harry Tracy Water Treatment Plant (HTWTP): standby power improvements include removing the four existing, smaller emergency generators and providing two permanently installed 2-megawatt (MW) emergency generators.
• Millbrae Yard: standby power improvements include replacing the existing emergency generator with a permanently installed 300-kW unit to enable this facility to function as an emergency operations center.
• San Pedro Valve Lot: standby power improvements include installing a permanent 20-kW emergency generator in a sound-attenuated masonry wall enclosure.
• Capuchino Valve Lot: standby power improvements include providing an electrical receptacle for a portable 30-kW engine generator.
• The project will also provide the trailer mounted engine generator that will be stored at the Millbrae Yard.

Scope Refinements
Originally the project also included a receptacle at Calaveras Reservoir to accommodate portable generator. After reviewing system needs, this receptacle was not found to be necessary, and instead a receptacle for a portable generator at the Capuchino Valve Lot was added to the project.
