East Penn's Advanced Batteries Play Key Role in Solar Energy Storage Project

Lyon Station, PA., 12 October 2011 - East Penn Manufacturing Co., Inc., and its subsidiary Ecoult, announces the launch of Public Service Co. of New Mexico's (PNM) Prosperity Energy Storage Project in Albuquerque, NM. This project integrates an Advanced VRLA (Valve-Regulated-Lead-Acid) and UltraBattery® energy storage solution with a separately installed 500 kW solar plant. Its purpose is to provide simultaneous voltage smoothingfor consistent energy levels and peak shifting to deliver energy when it's needed the most.

East Penn, through its subsidiary Ecoult, is bringing these breakthrough technologies to market as complete energy storage solutions and modules ready for custom integration. Ecoult engineered and integrated the energy storage system, and developed the Smart Grid platform that controls both the batteries and the power conversion system.

"This is an exciting time to be in the energy storage business. Advanced leadacid batteries can play a major role in solar and wind systems, smart grid technology, and other applications as well. The energy landscape is evolving, and we're well positioned to change with it," stated Sally Miksiewicz, CEO of East Penn."

This project was achieved with the collaboration of many key partners, led by PNM and including the Department of Energy Smart Grid Storage Demonstration Program, the University of New Mexico, Northern New Mexico College, Sandia National Laboratories, and Electric Power Research Institute. Ecoult also worked with a number of US manufacturers who supplied critical components of the project including S&C Electric Company that provided a Purewave(tm) PCS for power conversion and grid integration, Sea Box, Inc.'s contract services for assembly of containerized components, Peterson Panel's power panels, and KTR Associates' interconnection design.

This is the first of 16 Smart Grid energy storage demonstrations funded from the American Recovery and Reinvestment Act (ARRA) of 2009 to go live. Additionally, East Penn with Ecoult is commissioning a second site partially supported with ARRA funding, located at its Lyon Station, PA manufacturing campus. This will be a 3MW site and will provide continuous voltage smoothing using the UltraBattery®. It will serve a secondary application of 1 MWh for demand management for 1 to 4 hours.

Advanced VRLA batteries feature a design enhancement to East Penn's Deka Unigy VRLA battery technology that has been proven as an industry leading product for telecommunication and data center applications. This enhancement protects the battery from accelerated deterioration while performing multiple cycles in Partial State of Charge (PSOC) applications.

The UltraBattery® combines the advantages of the Advanced VRLA with the advantages of an asymmetric
supercapacitor. This enables the optimal balance of an energy storing lead battery with a quick charge acceptance, power discharge, and longevity of a capacitor, which is critical for High-Rate PSOC applications. Both advanced types of VRLA batteries are virtually 100% recyclable and made in the United States.

The information gained from these advanced battery projects will be a key component in furthering its integration into the commercial marketplace for wide spectrum of potential applications. Advanced VRLA and UltraBattery®'s current ability to serve the grid, renewable energy, and HEVs has the potential to have immediate impacts on cost effective energy conservation and clean energy generation. Ecoult's energy storage solutions are further proof of these implementations in action.
