PG&E seeks PUC approval for 75 MW of energy storage deals

Pacific Gas and Electric Co, the US electric utility held by PG&E Corp (NYSE:PCG), this week presented 75 MW of energy storage contracts for review and approval by the California Public Utilities Commission (PUC).

PG&E wants the projects to be realised due to a state requirement for investor-owned utilities to procure 1,325 MW of storage by 2020. Currently, the company’s share amounts to 580 MW. By the end of the year, PG&E expects some 30% of its retail power deliveries to come from renewables and it needs energy storage to integrate those intermittent sources.

The seven projects were chosen after PG&E issued a request for offers (RFO) to solicit proposals for energy storage schemes on December 1, 2014. The first of them are expected to become operational in May 2017.

The table below gives more details about the projects.

Project name	Counterparty	Technology	Size
Energy Nuevo	Amber Kinetics	Flywheel	20 MW
Molino	Hecate Energy	Lithium Ion Batteries	10 MW
Golden Hills	NextEra Energy	Lithium Ion Batteries	30 MW
Henrietta	Convergent	Zinc/Air Batteries	10 MW
Clarksville	Western Grid	Zinc/Air Batteries	3 MW
Old Kearney	Hecate Energy	Lithium Ion Batteries	1 MW
