Project Management Structure
There are currently ten power station projects being undertaken in the first phase of NIPP.
Planning & Design
Generation projects component of NIPP was initially commenced in 2004 with a “Committee for the Implementation of Seven Medium-Sized Power Plants in the Niger Delta” as an intervention to reduce the huge power generation deficit in the country and in aid of stabilizing the new Power Sector Reform Initiative of the Federal Government. Following the identification of the possible sites for the projects, the joint venture of Messrs Lahmeyer International GmbH and O. T. Otis Engineering Ltd was engaged as the Design and Management Consultant for the projects whose scope had to increase to include the additions to the national power transmission and distribution network infrastructure necessary to evacuate power generated from these new power plants as well as the grid capacity to wheel generated power to final consumers. Thereafter, the programme was named “National Integrated Power Project (NIPP)”.
Of the initially identified seven power plant projects, it was decided with regard to five (5) of the power plants – i.e. those sited in Calabar, Egbema, Ihovbor (Benin City), Gbarain and Sapele – the same type of medium-sized gas turbine units (18 Nos in total) were to be installed for economy of scale and ease of maintenance. Therefore, the contracting for these five plant was separated into:
- One contract with an original gas turbine manufacturer for the supply of all the 18 gas turbine units (including the auxiliary equipment, the generators and main transformers). This is referred to as OEM contract. This contract was awarded to General Electric (GE) to supply 18 units of GE model PG9171E (Frame 9) gas turbines.
- An Engineering, Procurement and Construction (EPC) contract for each of the power plant for the power station engineering, supply and installation of balance of plant equipment as well as the installation and commissioning of the GE gas turbines.
Omoku power plant project was initially conceived to be an extension of the Rivers State Government’s Omoku Power Station to be handled by the same contractor. It was later awarded as a stand-alone, fully independent power plant on turnkey EPC contract installing the same type GE9171E gas turbines (2 units).
The seventh project was to be the conversion of the open cycle gas turbines (OCGT) power plant at Aluminium Smelting Company (ALSCON) in Ikot Abasi into combined cycle gas turbines (CCGT). This was discontinued following the sale of the company by the Federal Government.
In 2007, four other power plant projects commenced by the defunct Power Holding Company of Nigeria (PHCN) was transferred to NIPP for completion. These are Alaoji Power plant and the second phase of the power plant projects at Olorunsogo, Omotosho and Geregu. The Alaoji and Olorunsogo projects are combined cycle gas turbine (CCGT) plants while Omotosho, and Geregu are open cycle gas turbine (OCGT) plants. The gas turbines at Alaoji, Olorunsogo and Omotosho are of GE PG9171E type but Geregu has Siemens type SGT5-2000 gas turbines. The contract structure for all four projects is turnkey EPC.
On each of the ten power station projects, the services of a project engineering consultancy firm was engaged to assist NDPHC in the supervision of the engineering and construction of the power station.
