Expansion of independent power plant

Okpai Power Plant Phase II, Delta State

To support the provision of power supply in Nigeria, the Independent Power Plant (IPP) Okpai Phase II project has been initiated by the Nigerian Agip Oil Company (NAOC), to increase the plants existing power generating capacity of 480 MW by a further 450 MW to provide a total 930 MW output into the Nigerian power supply grid.

The additional power generation is provided by means of a combined cycle gas turbine plant with two gas turbine generators and one steam turbine generator located 60 km south west from Onitsha in Delta State, close to the River Niger.
