New collaborations signal the company’s leadership in deploying technology to help stabilize pricing to support the ever larger numbers of EV owners. Wayne Gerdes – CleanMPG – March 19, 2022 Electrify America has now installed onsite, over 30 MWs of behind-the-meter battery energy storage systems (BESS) at over 140 DC fast charging stations around the country, including more than 90 installations in California. This is the largest roll-out of onsite behind-the-meter battery energy storage coupled with ultra-fast DC chargers in North America. The battery energy storage systems store power when electricity costs are low and supplement power during high points of consumption, minimizing impact on the electrical grid and mitigating demand surges to help Electrify America maintain consistent pricing. One of the obstacles utility providers face is “demand charges,” which are electricity surcharges on peak power usage designed to capture the marginal costs imposed on the grid by high-capacity, high-utilization infrastructure. When traditional demand charges are levied upon high-capacity, low-utilization infrastructure such as high-powered EV charging stations, they place a disproportionate cost burden on the station owners. While many states and utilities look to streamline electricity rates to better support public charging infrastructure, Electrify America’s investment in energy storage helps to facilitate the roll-out of ultra-fast DC fast charging where it may otherwise be cost-prohibitive. Electrify America’s investment in onsite behind-the-meter battery energy storage also has the potential to maximize renewable energy use. Energy storage can help store excess renewable energy to be used in times where those renewable sources may not be available, and further leverage the tailpipe emissions reductions that follow from transportation electrification. Beyond this installed energy storage portfolio, Electrify America is working on certification and initial roll-out of its next generation of onsite behind-the-meter battery energy storage early next year that will support higher peak power or demand mitigation capability in approximately the same footprint. In addition to leveraging battery storage installations to reduce utility costs and support more charging infrastructure, Electrify America is promoting vehicle to grid integration. With the help of Olivine, Electrify America is driving revenue from behind-the-meter services for its onsite battery energy storage assets, delivering consistent pricing to its customers and offering greater reliability than fluctuating gas prices. Behind-the-meter services such as demand response help support vehicle to grid integration by reducing the need for more costly and often more polluting peaking power plants. These services may otherwise be used to meet such incremental demand, decreasing the carbon profile and potential emissions associated with the electricity generation that powers Electrify America’s network. In the future, as utility regulations and energy markets evolve, Electrify America aspires to potentially provide power back to the grid from its energy storage to enhance the vehicle-grid integration benefits of its investments. To date, Electrify America’s behind-the-meter energy storage has already participated in over 190 demand response market events via Olivine in the California Independent System Operator’s wholesale energy market, CAISO – shifting over 125 MWh of on-peak energy to lower carbon intensity off-peak hours creating the largest Virtual Power Plant (VPP) offering in CAISO backed by DC fast charging coupled with behind-the-meter energy storage. Back in early 2019, Electrify America announced it was adding Tesla Battery Storage to 100+ DCFC Stations. Each site consisted of a 210-KW battery system with roughly 350 KWh of capacity. With a modular design, more capacity could be added over time. With more EVs hitting the road, Electrify America has designed its sites and electrical systems to easily enable future upgrades to meet the demand of the growing market and proactively engage with a changing utility landscape and rate structures.
