eMotorWerks, an Enel subsidiary, now serves California energy markets with smart-grid electric vehicle chargers and EVs

Proving the grid balancing potential of its smart-grid electric vehicle chargers, eMotorWerks, a subsidiary of the Enel Group's new advanced energy services division Enel X, successfully deployed a 30 MW, highly distributed virtual energy storage battery within California since the start of 2017.

With an energy capacity of 70 MWh and eMotorWerks' JuiceNet cloud software platform as the Battery Management System (BMS), the eMotorWerks virtual battery is active in California Independent System Operator (CAISO) wholesale day-ahead and real-time markets, dynamically managing charging loads to balance grid demand, reduce wholesale energy costs and mitigate the intermittency of renewables.

"Having proved at scale capabilities that no other EV charging technology has accomplished, eMotorWerks is aggregating and bidding EV loads at the wholesale level," said Val Miftakhov, CEO of eMotorWerks. "Our intelligent platform already delivers on grid integration, wholesale energy cost reduction and renewables integration with cost-effective load aggregation. It's time for utilities around the country and the world to take advantage of these capabilities and help grow this virtual battery to support our shared electrification and decarbonization goals."

Over 6,000 eMotorWerks residential JuiceBox and other JuiceNet-enabled chargers installed in California make up the 30MW virtual battery.

"Through eMotorWerks' virtual battery aggregations, EV drivers themselves can participate in the overall health of our grid and help reduce energy costs, utilizes cleaner power and maximizes existing infrastructure," said David Schlosberg, eMotorWerks VP of Energy Market Operations.

"Today, EVs are reaching the inflection point for mass adoption, and eMotorWerks is the preferred partner for electricity providers, vehicle manufacturers such as the recently-announced Honda collaboration, and regulators to develop programs to deploy virtual batteries in their territories. Collectively, we have the opportunity to future-proof our electricity systems now by ensuring EV grid integration "off the lot" to prepare for a reliable electricity system dominated by EVs, renewable energy and storage."

"The technology advancements we are delivering in smart-grid charging is analogous to the technology advancements project developers leveraged when pioneering third-party finance in the solar industry 10 years ago," said Preston Roper, Chief Marketing & Operating Officer of eMotorWerks and former solar industry executive.
