The “Duck” Chart
Demand Response Energy Storage Systems
For Utilities: Large customer load centers serving as “virtual power plants” for utility
and grid services Reliable, grid-scale load reduction = firm, flexible capacity resource for
utilities and grid operators Provides alternative to costly distribution upgrades For Facility Owners & Host Customers: Lowers electricity costs through “peak shaving” and reduction of utility
demand charges Firms, shapes and integrates on-site generation for optimal rate design Provides supplemental or emergency back-up generation for critical loads Supports load balancing for “islanding” or microgrid Increases revenues from utility incentive programs

Aggregated Energy Storage Systems have the potential to displace natural gas “peaker” plants, avoid costly distribution upgrades and help utilities integrate intermittent renewable generation.

AMS: A Leader in the Emerging Storage Market
“San Francisco's Advanced Microgrid Solutions (AMS) is one of several young companies positioned at the leading edge of innovation and development of behind-the-meter advanced energy storage solutions. Marking a major milestone for the company, SCE on November 5 awarded AMS “a 50-megawatt contract...to develop the first grid-scale fleet of Hybrid-Electric Building project in the world.” - Renewable Energy World.COM 2.14.2015 Energy Storage Emerges as an all-purpose grid asset
“Typically, a utility copes with high demand by bringing an additional power plant online; instead AMS will reduce the utility’s load by up to 50 megawatts—enough to power 20,000 homes. ‘Susan and her team are unlocking the notion of using customer-side resources as capacity,’ says Julie Blunden, an energy consultant who chairs the governing body for the public-private consortium CalCharge. ‘That is an absolutely tectonic shift for utilities.’” Popular Science, 5.20.2015 Keeping the Lights on with Virtual Power Plants
“…the AMS Tesla battery announcement steps things up a notch. The idea is for AMS to use up to 500 megawatt-hours (MWh) of Tesla batteries, in partnership with the company Black & Veatch, for engineering and construction services. If Black & Veatch rings a bell, you could be thinking of any number of microgrid and renewable energy projects the global firm has a hand in, including the construction of fueling stations for fuel cell electric vehicles in California. The point is, if the Tesla brand is enough to give AMS street cred, the association with Black & Veatch puts it over the top.” Clean Technica, 6.5.2015 Stealth” Woman-Owned Startup Nails Tesla Battery For Hybrid-Electric Buildings
“…If batteries live up to their promise — a very different electric grid is about to emerge, one free of the long-time constraint that electricity must be consumed almost as quickly as it is produced….Already a new competitive player is emerging, the energy storage aggregator. (Stem and Advanced Microgrid Solutions are examples.) Aggregators install energy storage in buildings and then group the capacity into a portfolio. They then offer the combined storage as a dispatchable asset for use by the grid, perhaps for peak shaving, demand response or ancillary services. These load aggregators, who Hill sees as poised for tremendous growth, take on the risk required to create the kind of new grid imagined in New York’s Reforming the Energy Vision (REV). - Energy Efficiency Markets.com 1.17.2015 “Will Batteries Live Up to their Promise For Energy Storage?”
