The Geregu II gas turbine power plant in Nigeria

In the Nigerian state of Kogi, Siemens has completed the Geregu II gas-turbine power plant in Ajaokuta on schedule. The customer is Niger Delta Power Holding Company (NDPHC), the state-run energy provider in Nigeria. As part of the turnkey gas turbine power plant, Siemens supplied three E-class gas turbines as well as the associated generators. With an electrical capacity of 434 megawatts (MW), the plant will play an important role in the expansion of the power supply in Nigeria. Ajaokuta is located approximately 200 kilometers south of the Nigerian capital Abuja. Following the Afam V and Geregu I plants, Geregu II is now the third gas-turbine power plant to be constructed by Siemens in Nigeria as a turnkey project and completed on schedule. The scope of delivery supplied by Siemens for Geregu II included three SGT5-2000E gas turbines, three SGen5-100A generators, as well as all the electrical systems and the SPPA-T3000 control system. Siemens had also supplied three E-class gas turbines, generators, and the control technology for the Geregu I power plant. Siemens has already sold over 460 SGT5-2000E gas turbines worldwide. With over 14 million equivalent hours of operation, this turbine has a very high amount of operating experience.

Nigeria is Africa’s most populous country with extensive oil deposits, and with a gross domestic product of over 200 billion US dollars, its economy is one of the largest in Africa. The Nigerian government has developed the Vision 2020 program to further expand the country’s energy system. By 2020, Nigeria plans to increase the country’s generation capacity by five to eightfold from its current level of approximately 5 gigawatts (GW). In April 2012, Siemens met with the Nigerian President to sign a memorandum of understanding regarding the delivery of additional power plant components.

“The SGT5-2000E gas turbines that were installed in Geregu II gas turbine power plant are suitable for all load ranges, particularly for peak load operation. Thanks to their reliability, robustness and service friendliness, they are ideal for the requirements of the Nigerian market. In Nigeria, planning is already underway for additional projects using this type of turbine,” said Lothar Balling, head of Gas Turbine Power Plant Solutions at Siemens Energy.

“The Geregu II power plant has strategic significance when it comes to improving the power supply in our country as well as for the stability of Nigeria’s power grid. We’re very satisfied with how this important project has been implemented, and we’re proud to be working with Siemens,” said James A. Olotu, Managing Director of NDPHC.
