Project Status

Project Update

The Port developed the preliminary microgrid design at a level sufficient to complete a competitive procurement for final microgrid design and build services. In parallel, the Port has begun warehouse roof replacement work to support the solar PV array installation, as well as energy efficient lighting installation work.

The Issue

California ports are electrifying their operations to move toward zero emission operations. The move to all-electric terminals will result in many terminals at least tripling their peak power consumption, while becoming more susceptible to electricity price uncertainties and vulnerable to operational disruptions due to losses of grid power. The Port of San Diego Tenth Avenue Marine Terminal (TAMT) provides critical functions such as pumping jet fuel to the nearby airport as well as processing bulk perishable food imports for distribution throughout California and beyond.

Project Innovation

The project will develop a new, permanent, renewable microgrid at the Tenth Avenue Marine Terminal that can be replicated at other seaport terminals and distribution facilities throughout California, the U.S., and internationally. The project will incorporate solar photovoltaic renewable generation, battery energy storage, energy efficiency improvements, and a centralized microgrid controller to allow key elements of the terminal to remain operational when islanded from the electrical grid for a minimum of 12 hours.

Project Benefits

The project will create a replicable approach for developing a solar-powered, resilient microgrid in a port or other industrial setting that will provide power to critical loads and allow key elements of a terminal to remain operational for 12 hours or longer when islanded from the grid.

Lower Costs

Affordability

The project will lower customer costs by reducing peak demand charges. Additionally, ratepayer costs will be lowered by reducing the need for electric utility infrastructure improvement through consistent management of peak loads from industrial sites, which are large energy users. The project will investigate different options to reduce capital investments and document cost effective options for ratepayers implementing similar projects.

Increase Safety

Safety

The microgrid will increase energy resiliency resulting in a safer staging area that can be used for emergency relief, supplies, and fuel in the event of a disaster that causes a disruption to the electrical grid.
