## Largest Utility Energy Storage Purchase in History Announced in California Southern California Edison Names Suppliers for 261 MW of Energy Storage Projects Comprising Multiple Applications, Technologies and Services

**PRESS RELEASE**

November 5, 2014

Southern California Edison (SCE) today announced the selected suppliers   
and projects for the largest grid-connected energy storage purchase in U.S. history – more than   
five times greater than the utility’s minimum energy storage procurement authorization of 50   
MW, per California Public Utilities Commission (CPUC) ruling. Pending approval of the projects   
by the CPUC, SCE will purchase 261 MW of energy storage resources. 

The California Energy Storage Alliance (CESA), a membership-based advocacy group   
committed to advancing the role of energy storage in the electric power sector, hailed the   
decision as another significant step in the commercialization of storage on the power grid – and   
California’s leading role in that power market transition.

“This is a monumental decision – arrived at after a team of SCE experts studied more than   
1,800 offers for various storage solutions, as well as other preferred resources and traditional   
generation,” said Janice Lin, Executive Director of CESA. “The fact that SCE far exceeded the   
minimum amount of energy storage they were ordered to purchase after comparing multiple   
solutions head to head, demonstrates that energy storage can be competitive with other   
preferred resources on both performance and value, and that it’s now an integral part of the   
utility planning tool kit in California.”

This procurement effort also marks the first time SCE has contracted with energy storage   
projects through a competitive solicitation. Once deployed, the systems will provide a number of   
services to SCE’s power grid, including ensuring adequate available electrical capacity to meet   
peak demand. 

The companies named to provide storage systems and the amounts are:

• NRG Energy 0.5 MW  
• Ice Energy Holdings, Inc. 25.6 MW  
• Advanced Microgrid Solutions 50.0 MW  
• Stem 85.0 MW   
• AES Energy Storage 100.0 MW

“This solicitation is the first time that such a wide range of new diverse resources were directly   
competing in the purchasing process,” said Colin Cushnie, SCE vice president, Energy   
Procurement & Management. “No single energy source can give us everything we need all of   
the time, particularly with our emphasis to use environmentally clean resources. To provide for   
flexibility, we need to accommodate a mix of energy resources.”

California utilities leading the way  
With clear leadership and momentum, California utilities are proving the value of energy storage   
in various applications from transmission-connected to customer-sited systems. There are   
currently 112 operational energy storage projects in California, according the U.S. Department   
of Energy’s Global Energy Storage Database ([www.energystorageexchange.org](https://gesdb.sandia.gov/)).

The progressive clean energy policies of the California Public Utilities Commission (CPUC)   
have helped make the state a global leader in energy storage, with substantial progress   
achieved since its 2013 decision ordering SCE’s storage procurement. The state is currently   
focused on implementing AB 2514, which requires investor-owned utilities to procure 1.325 GW   
of energy storage by 2020. AB 2514 also required California’s Publicly Owned Utilities to   
evaluate procurement targets for energy storage. In October, the Los Angeles Department of   
Water and Power (LADWP) released a plan to procure 178 MW of energy storage capacity by   
2021.

The California Energy Storage Alliance (CESA) has been an active stakeholder in the   
legislative, rulemaking, and implementation process in the state. CESA represents more than 85   
organizations dedicated to making energy storage a mainstream resource that will enable a   
cleaner, more efficient and reliable electric power system. All five of the SCE storage project   
winners are CESA members.
