Convergent Energy + Power, a market-leading energy storage asset developer, has announced a 10 MW, 40 MW-hour project award from Pacific Gas and Electric Company (“PG&E”). This project was selected as part of the first round of PG&E’s highly competitive Energy Storage Request For Offers solicitation, with results announced December 2, 2015.

“Energy storage can provide location-targeted capacity that relieves grid constraints and meets reliability standards, while also increasing grid flexibility and resiliency,” said Johannes Rittershausen, Convergent’s CEO. “Convergent appreciates the opportunity to work with the PG&E team to bring the benefits of commercial energy storage to California’s electric grid.”

As a technology-neutral developer, Convergent offers a wide array of technology options, with currently announced projects including a 3 MWh, 6-hour continuous discharge battery used for transmission and distribution deferral in Central Maine Power service territory as well as a 5 MW, 6-minute flywheel and 7 MW, 1-hour battery used for frequency regulation and voltage support services by the Ontario Independent System Operator.

PG&E selected a Convergent proposal with four hours of continuous discharge capability for peak shaving and grid balancing services. The utility-scale energy storage system will employ a low-cost, long-life zinc-hybrid cathode (ZnythTM) battery technology, provided by Eos Energy Storage.

“Eos is proud to support Convergent’s mission of improving grid reliability and resiliency,” said Eos CEO Michael Oster. “At a price of $160/kWh, our Aurora DC battery system enables locational capacity that is cost competitive with incumbent solutions – such as gas peaking plants and copper wire – and moreover distributed within the grid’s most congested locations.”

Eos has deployed systems with major utility partners including Con Edison of New York and Engie (formerly GDF Suez). The company recently announced a California Energy Commission funded project to deploy an Aurora system at PG&E’s San Ramon Technology Center. Eos is ramping up volume production with major contract manufacturing partners and is delivering numerous MW-scale systems in 2016.

“This is just the beginning of a rapidly expanding energy storage industry,” says Rittershausen. “Utilities – as well as end-users of electricity – can take advantage of a variety of reliable, responsive and environmentally friendly energy storage solutions to overcome expensive grid infrastructure challenges. PG&E’s project award further demonstrates Convergent’s reputation and capabilities as a leading developer of energy storage assets.”
