EDF Renewables North America (EDFR)announced that the Port of San Diego has selected it to build a 700 kW / 2,400 kWh Microgrid Infrastructure Project. The project means that the Port’s Tenth Avenue Marine Terminal (TAMT) will be able to detach from the main grid and go into “island mode” when necessary. The project was approved by the Board of Port Commissioners on November 10, 2020.
EDFR said that the Microgrid Infrastructure Project, consisting of a battery storage system and electrical infrastructure, should save the port up to $3.2 million during regular operations over 20 years. The system will provide emergency back-up power to the Port-operated facilities, including security infrastructure, lights, offices, and existing jet fuel storage system in support of the Port’s role as a Strategic Port.
Microgrids are innovative systems that integrate batteries, renewable generators, load control, and traditional onsite generators with intelligent componentry to create a system that ensures continuity of operation during power outages, said EDFR. The microgrid at TAMT will advance the Port’s use of renewable energy, reducing greenhouse gas emissions (GHG) on and around the terminal and aligns with the Port’s Climate Action Plan.
During typical grid connected operations, the battery system optimizes operations by allowing the facility to draw from the stored energy during the utility’s expensive evening on-peak period. The energy storage system will also reduce utility costs by discharging the battery to mitigate spikes in usage thereby lowering demand charges. Meanwhile, during a power outage, instead of using only a diesel generator for backup power, the Microgrid can support the facility resulting in fuel savings and reduced greenhouse gas emissions.
“The microgrid project provides numerous benefits for not just the Port, but our surrounding communities and region,” said Vice Chair Michael Zucchet, Port of San Diego Board of Port Commissioners. “We’re delighted to be a leader in the process of cargo terminal electrification. Through our testing, monitoring and evaluation, we will share our findings with other ports in California and around the world.”
