New Hybrid Electric Power Generating Plant Will Serve Chile's Northern Grid

SANTIAGO, Chile & ARLINGTON, Va.--AES Gener and AES Energy Storage today announced the selection of Parker-Hannifin to supply advanced battery energy storage systems for their new Cochrane power station. The battery energy storage system will be supplied by Mitsubishi Corporation with the lithium ion battery module manufactured by GS Yuasa and the lithium ion battery cells by Lithium Energy Japan, a joint venture of Mitsubishi Corporation and GS Yuasa. The project is the companies' third energy storage facility in Northern Chile, integrating 20MW of advanced battery-based energy storage with a 532MW thermal power plant. The project is owned by AES Gener, the second largest power generator in the country, and Mitsubishi Corporation.

"We are pleased to announce our relationship with Mitsubishi Corporation and GS Yuasa, leading suppliers of advanced batteries and to continue working with Parker, a leader in power conversion systems," said Chris Shelton, President of AES Energy Storage. "These are strong partners among a robust global supply chain for energy storage."

"We are very excited about this addition of the battery storage system to our Cochrane power station. We already have battery energy storage systems in our Angamos and Norgener power plants. It will be good for the supply of power in the northern grid, and also for the stability of the system," said Felipe Cerón, CEO of AES Gener S.A.

The Cochrane facility being developed by AES Gener, will incorporate AES Energy Storage's Advanced Reserves product including patented controls, a highly reliable modular system architecture, and industry leading operational support. The advanced lithium-ion battery modules for the project will be supplied by GS Yuasa, a world's leading manufacturer of batteries, and the battery cells will be supplied by Lithium Energy Japan, a leading lithium ion battery manufacturer who supplies large capacity cells to Automotive and Industrial Application from its world's first mass production plant. The Grid Services division of Parker-Hannifin will provide power conversion and system-level services. The battery energy storage systems in combination with the energy produced by the Cochrane generating station will provide responsive, reliable power in the Northern Grid.

"It is our great honor to cooperate with AES, a leader in grid storage," said Masaji Santo, Senior Vice President, Division COO of Environment and Infrastructure Business Division of Mitsubishi Corporation. "We look forward to working with AES in scaling up new systems to serve reliability and peak power needs throughout the industry."

"AES brings innovative solutions through their deep understanding of the utility power sector," said Jim Hoelscher, President, Grid Systems for Parker-Hannifin. "We look forward to working on another storage project in Chile and to continuing the work with AES though our new global Grid Systems division."

AES Gener and AES Energy Storage have previously developed energy storage projects at the Norgener and Angamos power stations. The first of these, the Los Andes Battery Energy Storage System (BESS) has been delivering grid reliability services since 2009.
