GE Energy Storage is providing the storage for a 500 kWh load-shifting project for the Southern California Edison project at the Discovery Science Centre in Santa Ana.

The project aims to shift 10 – 20% of the centre’s daily electrical consumption to off-peak hours by using a 500kWh storage system to provide backup power.

GE is providing a turnkey Durathon battery energy storage system and Princeton Power Systems is providing the invertor control system to integrate with the storage system to load shift to enable the Centre to reduce its peak electricity usage and thus its electrical bill.

Kellee Preston, Vice President of operations at Discovery Science Centre, said: “We are eager to demonstrate technologies that can reduce our energy cost while adding to the reliability of the electric grid. We’ll be able to use the system to increase outreach on energy issues and better explain the benefits that storage can bring to the electric grid system.”

Southern California Edison is managing the project as part of California’s statewide initiative to reduce peak demand on the electrical grid. Along with the Centre, SCE will monitor the performance of the system and use it to assess how remote storage systems can bolster distribution network’s performance.

California becomes first state to introduce energy storage targets

The California Public Utilities Commission (CPUC) has authored a proposed decision to install 1.325GW of energy storage across the state by 2020. Commissioner Carla Peterman has set out year-by-year procurement targets for Southern California Edison (SCE), San Diego Gas & Electric (SDG&E) and Pacific Gas & Electric (PG&E).

The installed energy storage can come from any type of technology and can be employed for a variety of functions such as capacity, ancillary services and peak shaving.

PG&E and SCE are each required to install 580 MW of capacity and SDG&E must acquire 165 MW in total by 2020. The utilities would be allowed to own some of the energy storage capacity as part of their distribution system planning process.

This is the first time energy storage has been included in a State policy, supporters hope it will create a market for electrical energy storage solutions. There has been opposition to the proposal from stakeholders, including generator set trade representatives, who believe electricity storage suppliers should compete in the capacity market with other technologies rather than being prioritised in such a way.

The first installations of capacity must be no later than December 2014.
