The alliance combines GE's Durathon* battery technology for grid energy storage systems and Xtreme Power's extensive experience as an integrated energy storage turn-key solutions provider.

September 10, 2012 (Schenectady, NY and Austin, TX) – GE Energy Storage, a unit of GE Transportation (NYSE: GE) and Xtreme Power, a privately held Austin, Texas company have formalized a strategic alliance to work together to provide cutting-edge energy storage solutions. The alliance combines GE's Durathon* battery technology for grid energy storage systems and Xtreme Power's extensive experience as an integrated energy storage turn-key solutions provider. The new GE Durathon battery products, which can last up to ten times longer than conventional lead acid batteries and store more energy in half the space, are the result of a $100 million initial investment in battery technology developed at GE's Global Research Center in Niskayuna, NY. GE's Durathon battery technology, when paired with Xtreme Power's Xtreme Active Control Technology** (XACT), should enable safer and highly efficient storage of massive quantities of electricity at low cost for grid applications. XACT is an innovative proprietary control system architecture that offers sophisticated control algorithms, real time response, remote monitoring, and optimized power management. Together, GE and Xtreme Power expect to tap a global segment looking for effective and efficient energy storage on the electric grids of the world, both old and new.

"Teaming up with Xtreme Power provides customers in the energy space access to turn-key solutions based on breakthrough Durathon battery technology," said Prescott Logan, General Manager of GE Energy Storage. "Our combined team's proven experience in integrating energy storage technologies with power conversion systems and the grid, as well as installing and operating multi-megawatt energy storage systems will bring real life-cycle value to our customers."

"We're honored to be working with GE Energy Storage, and confident that together we'll help deliver tomorrow's energy technology to the world's markets today," said Alan Gotcher, President & CEO of Xtreme Power. "GE's world-famous technology, matched with Xtreme Power's XACT control platform and systems integration expertise, is a win for everyone concerned about efficient, cost effective energy storage."
