History
The station was built in 1964 with an installed capacity of 2X36MW or 72MW from two Stal-Laval gas turbines and began operations in 1966. Then the station was called Delta I under the Electricity Corporation of Nigeria (ECN), a precursor to the Nigerian Electric Power Authority (NEPA) and its successor, the Power Holding Company of Nigeria (PHCN).

In 1975, six units of General Electric (GE) Frame 5 gas turbines (20MW each) were installed in the station known as Delta II, after the merger of Niger Dam Authority (NDA), Kainji, and the ECN to form the National Electric Power Authority (NEPA).

In 1978, an additional six units of GE Frame 5 gas turbines, like the ones installed in 1975, were added to Delta Power Station (Known as Delta III) to boost the installed capacity to a total of 312MW. In 1991, six 100MW (600MW) GE Frame 9 gas turbines were added. From 2000 to 2008 Delta II and Delta III GE units were upgraded to 150MW stations each: built by Hitachi. The control systems were upgraded to Mark V, a fully computerized control system for Delta II and III. While Delta I was scrapped. Delta IV control system was also upgraded to Mark V by GE of USA which built the station.

On September 25, 2012, Transcorp Ughelli Power Limited (TUPL) (which comprises Wood Rock Energy Resources Limited, Symbion Power LLC, Thomassen Holding Limited, Medea Development S.A., Tenoil Petroleum and Energy Services Limited and PSL Engineering and Control Limited) won the $300m bid for the acquisition of the Ughelli Power Plant, one of the six power generation companies of the Power Holding Company of Nigeria (PHCN) being privatized by the Federal Government of Nigeria. Symbion Power was divested in September 2015.

On November 1, 2013, Transcorp Power officially took physical ownership of Ughelli Power Plc, the owner and operator of Ughelli Power Plant following a handover ceremony hosted by the Federal Government of Nigeria.
