Certifications for New Plant in Springboro, Ohio
170,000 Square Feet of State-of-the-Art Manufacturing Space With Future Annual
Production Capacity of 1.2 Million Battery Modules 


SPRINGBORO, Ohio, Nov. 4  /PRNewswire-FirstCall/ -- The growing hybrid electric
vehicle and stationary power markets will now be better served with the
commissioning of Texaco Ovonic Battery Systems' new production plant in
Springboro, Ohio, near Dayton.

The only manufacturing plant of its kind in the U.S., construction of the Texaco
Ovonic Battery Systems facility began in October 2002.  It features 170,000
square feet of manufacturing space, which is twice the size of the plant it
replaces in nearby Kettering, Ohio.  State-of-the art manufacturing equipment is
now in place at the Springboro plant, with a future annual production capacity
estimated at 1.2 million battery modules when fully equipped.

Texaco Ovonic Battery Systems L.L.C. is a 50-50 joint venture between a
subsidiary of ChevronTexaco Corp. (NYSE:CVX) and a subsidiary of (NASDAQ: ENER).
 Texaco Ovonic Battery Systems is helping to bring advanced nickel metal hydride
(NiMH) batteries into Energy Conversion Devices Inc. widespread commercial
production for transportation and stationary applications.

Thomas S. Neslage, President and Chief Operating Officer of Texaco Ovonic
Battery Systems, said, "The achievement of QS 9000 certification and ISO 14000
certification is an important milestone in our business strategy.  We are
demonstrating that our goal at Texaco Ovonic Battery Systems is to deliver
advanced high quality system solutions that offer value and reliability.  In
fact, some of the first modules from the plant will be delivered to the new
Energy Center facility under construction by Grand Valley State University in
Muskegon, Mich.  The University has selected our NiGEN(TM) 80 kilowatt hour
energy storage solution which will be used for peak shaving and load leveling.
The planned installation of this solution is timely given the recent power
interruptions experienced in the Northeast."

David Garman, Assistant Secretary for Energy Efficiency and Renewable Energy,
U.S. Department of Energy commented, "We are very pleased to see that Texaco
Ovonic Battery Systems has completed its state-of-the-art Ovonic(R) nickel metal
