Dynalectric was part of the team constructing these two facilities: a 30-megawatt (MW) storage facility in Escondido and a smaller 7.5 MW facility in El Cajon. A total of 24,000 batteries were installed to store and release energy to customers during peak demand times.
This energy storage project goes along with San Diego Gas and Electric’s (SDG&E) company values of providing safe, clean, and dependable energy to all of San Diego and other cities in southern Orange County.
Dynalectric San Diego coordinated and worked side by side with the engineers and third-party vendors to help ensure both sites would operate properly and to the client’s satisfaction.
Our crew installed a large amount of underground conduit and a grounding grid system while maintaining the required earth disturbance standards. We also received, set, and installed 30 modular cores, 15 medium voltage transformers, and two control houses while the entire site was under construction.
Other work included installation of the fire alarm and life safety and telecommunications systems, and the creation of a 24/7 assembly line to receive, build, and install the batteries that were racked inside the core units.
SDG&E was the first company to achieve California’s goal of providing 33 percent renewable energy through transitioning to electric cars and creating customer programs that promote energy efficiency.
