OVERVIEW

The Kin Thermal Power Station No. 1 unit began operations in February 2002. Planned and developed by The Okinawa Electric Power Company, Incorporated, this 220-MW coal-fired thermal power station has the largest generating capacity in Okinawa. The steam specifications at the power station are as follows: the main steam pressure at the turbine inlet is 16.57 MPa, the main steam temperature is 566°C, the reheat steam temperature is 566°C and the condenser vacuum is 6.67 kPa. The turbine model employs a high-medium pressure single flow turbine (SF-40) and a compact single-casing turbine design. During construction, new and conventional construction methods helped improve efficiency. As a leader in engineering, Hitachi employed a full turnkey method encompassing both civil engineering and construction to successfully complete construction of this plant.
