California utilities bet on EV charging to relieve strain on grid


The development means EMotorWerks will participate in the California Independent System Operator (CAISO)’s Demand Response Auction Mechanism (DRAM).

EMotorWerks says it will provide precise EV charging load curtailment from its JuiceNet network of EV charging stations to the wholesale real-time energy markets.

According to a press statement, the participation of EMotorWerks in CAISO marks the first aggregated EV charging station offering within the real-time energy market.

EMotorWerks claims JuiceNet enables directly-controlled electrical assets to provide near-instantaneous response to CAISO signals using its cloud-based load management and dispatch.

For EV charging loads, the solution provides predictive modelling that aligns driver behaviour and charging needs with local and regional level energy requirements of the grid.

DRAM is a California programme that allows demand response capacity providers to be paid monthly for energy reductions they promise to deliver in the coming year.

EMotorWerks and grid capacity balancing

In July, 2015, EMotorWerks forged a partnership with operational intelligence company OSIsoft to improve EV charging and grid capacity balancing.

The deal included utilizing the operational intelligence in OSIsoft’s system to combine sensor-based data from EMotorWerks’ network of JuiceBox charging stations with data from electrical utilities and Independent Service Operators (ISOs).

Commenting on the tie-up between the two Californian smart tech companies, Valery Miftakhov, said: “The PI System is used as the data infrastructure at all ISOs and RTOs in the US, and is therefore a natural choice for us to leverage for delivering superior service.”

The deal came after a new research confirmed North America as the leading global market for light duty plug-in electric vehicles.

Navigant Research forecasts the market to grow to more than 1.1 million vehicles sold annually by 2024 in the region.
