2-8. Media News - Philippines Case

Hitachi To Help Overseas Firms Conserve Energy2005/06/18, 03:07, Nikkei English News, 279 words

TOKYO (Nikkei)--Hitachi Ltd. (6501) is expanding its energy service company (ESCO), which helps firms cut electricity use at factories, to businesses abroad.

In ESCO operations, Hitachi examines a production site, sets up energy-saving equipment and then receives a service fee based on the resulting cost reductions.

Hitachi started the service at the Philippines hard-disk drive plant of its U.S. subsidiary. It plans to install a boiler that recovers heat from the factory's diesel engine generator and powers a freezer that cools electronic parts.
