World's Largest Medium-speed, Four-stroke Diesel Power Plant Delivered to OEPC

Tokyo, July 4, 2011 — Kawasaki Heavy Industries, Ltd. announced today that it has delivered an 18-MW diesel power generator to the Okinawa Electric Power Company, Incorporated (OEPC). It’s the world's largest diesel power generation system driven by a medium-speed, four-stroke engine. Far exceeding Japan's standard output of 10 MW, this power generator sets a new bar for single unit systems.

The order for the power generator came in August 2008 as a full-turnkey project designed to augment the No.5 generator at OEPC's Ishigaki Power Plant No.2. Kawasaki was responsible for everything from the design of the plant, supply and installation of engines, power generators, power distribution switchgears and control units, to civil engineering and construction work.

OEPC is working to boost its power facilities’ output to meet a rapidly growing demand for electricity that is being fueled by Ishigaki Island’s thriving resort industry. Up until now the Ishigaki power plant had been relying mainly on its three large-sized, 10-MW diesel generators, also supplied by Kawasaki. The newly added 18-MW power generator will help boost OEPC's capacity to supply electricity throughout the island.

Kawasaki continues to fuel a brighter future with distributed power generation systems as it takes its energy and environmental business to new heights in order to meet the world’s growing need for power.
