312MW of Power
The Gas Turbine Station located at Kilometer 20 Ughelli-Patani Road, before Ughelli Town
The station was built in 1964 with an installed capacity of 2X36MW or 72MW from two Stal-Laval gas turbines. Then the station was called Delta I under Electricity Corporation of Nigeria (ECN).
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 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, as follows:
Delta I, 2 X 36 72MW
Delta II, 6 X 20 120MW
Delta III, 6 X 20 120MW
4 Power plants
With 4 power plants Delta I, Delta II, Delta III and Delta IV, we have an installed capacity of 900MW.
With over 49 years of service we provide auxillary facilities for staff such as housing, medicare and school.
The station was upgraded in 1991 with the addition of 6 X 100MW (600MW) GE Frame 9 gas turbines.
From 2000 to 2008 Delta II and Delta III GE units were upgraded to 150MW station each: built by Hitachi of Japan. 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.
Today, the generation capacity of Transcorp Power stands at 900MW with the Delta II, III & IV running at full capacity.
Method of Production of Electricity
The gas turbine uses natural gas and compressed air as fuel to burn and rotate the shaft that turns the generator thereby generating electricity. Excitation is necessary to produce the required magnetic flux.
Uses of Electricity
Most of the electricity is transported through step up transformers and a network of conductors to various locations around the country in the form of a grid. Some units of the electricity generated are utilized locally within and outside the plant.
Hydrogen Gas Production Plant
Hydrogen gas (H2) is produced in the station for cooling the heaven General Electronics (GE) turbine generators of Delta IV.
Plant Details Model: 00700
Capacity: 2 x 15Nm3/h
Frequency: 50Hz Date of
The plant is equipped with sprinkler and hydrant firefighting systems with automatic CO2 high sensitive flame detector and combating mechanics for fire emergency.
