O&M / IPP and After-sales Service

Hitachi Zosen provides a comprehensive O&M (operation and maintenance) service designed to ensure stable and consistent operation of power generator systems over many years.
The O&M service includes legally mandated inspection and testing by skilled engineers as well as technical support and emergency call-outs to system faults and remote operations monitoring.
Following liberalization of the power industry in 1995, Hitachi Zosen has also been involved in the IPP (power wholesaling) sector.

The Hitachi Zosen Ibaraki works and power station, an IPP facility that supplies power to the Tokyo Electric Power Company, houses two combined cycle power generator systems featuring GE industrial mid-sized gas turbines and steam turbines with a combined power output of 219,000 kW.
Hitachi Zosen also operates three Wartsila diesel power generators (combined output 22,000 kW) at the facility on behalf of a power producer and supplier (PPS).

The Kawasaki power station (four gas engines with combined output of 26,000 kW) and Maizuru power station (five diesel engines with combined output of 35,000 kW) are both operated by Hitachi Zosen under PPS agreements.
