Aggregated Behind-the-Meter Services Provides New Revenues for Customers: A Model for the Future of Energy Storage

Santa Clara, Calif. October 8th 2015 – Green Charge Networks, the largest provider of commercial energy storage in the U.S., today announced its entry into the California Independent System Operator market. Under its shared-savings Power Efficiency Agreement (PEA), Green Charge has contracted 61 systems and 13.3 megawatt-hours with customers throughout California to take part in utility or ISO programs. CAISO and state utilities are observing how distributed customer-sited energy storage at scale can make a meaningful impact to power efficiency across the grid.

Green Charge’s core business is to reduce commercial electric bills by providing peak demand shaving services. In addition, customers further enrolled in CAISO or utility programs through Green Charge are able to leverage the unused capacity of their energy storage system to earn extra revenues, amounting to hundreds of thousands of dollars in incremental value. Serving as a model for the future of aggregated energy storage services, California’s Mountain View-Los Altos High School District’s 1.08 megawatt-hour deployment is taking part in Green Charge’s ISO bidding program.

“The MVLA high school district, located in the heart of Silicon Valley, is the birthplace of high tech innovation; to play an integral part in the future of energy storage is inspiring, ” said Mike Mathiesen, associate superintendent of business services at MVLA. “For many schools, reducing demand charges necessitates battery usage during only a few hours per day or per month. With Green Charge aggregating our systems to take part in market programs gives us a new source of revenues well beyond our demand charge bill savings.”

With the growth of solar on the grid, utilities are increasingly struggling to ramp-up capacity in the late afternoon/early evening hours, in particular when demand is highest in the summer months. Load growth within certain circuits is also placing more and more stress to the distribution network during peak times. Green Charge identifies and qualifies sites within targeted circuits, and develops the distributed energy storage program required to provide adequate grid relief. With systems deployed throughout many California school districts, Green Charge is assisting utilities by leveraging the fully-available capacity of its systems to provide energy on demand to the grid during peak hours.

“Empowering the end customers to make economic decisions on energy is the fastest and most scalable path towards energy storage adoption,” said Vic Shao, CEO at Green Charge. “California is providing meaningful incentives through the CPUC’s Self-Generation Incentive Program (SGIP) to seed the emerging marketplace for distributed energy resources. This has given customers the financial wherewithal to gain energy independence and bring virtual power plants into reality with networked customer sited energy storage.”

By the Numbers:

  • 13.3 MWh contracted for demand reduction and ISO or utility programs participation, under Green Charge’s Power Efficiency Agreement
  • 61 systems
  • $150,000 – 250,000 in expected extra revenue
  • Various energy storage system sizes from 60 kWh up to 2MWh
  • Mix of indoor and outdoor systems
