The Transmission Company of Nigeria (TCN) has granted site access to Mainstream Energy Solutions Limited (MESL) to begin construction of 2x330kV transmission bays at the Kainji Substation in Niger State.
The handover, conducted on Friday, June 5, marks the commencement of works aimed at expanding transmission capacity and improving power evacuation from the Kainji Hydro Power Plant to the national grid.

Under the project, MESL will execute the construction of two 330kV bays, covering civil, electrical and mechanical works, as well as testing, commissioning and other related technical activities.
On completion, the facility is expected to enable the evacuation of an additional 220MW from two generating units (1G3 and 1G4), each with a capacity of 110MW, thereby boosting output from the Kainji power complex.
Speaking at the ceremony, the General Manager, Materials Control and Stores, TCN, and Chairman of the Project Technical Committee, Engr. Abdulkadir Gwaram Adamu, described the development as a major step in strengthening Nigeria’s transmission infrastructure.
He said the project, being fully funded and executed by MESL at no cost to TCN, would ensure seamless evacuation of power from the new turbines into the national grid upon completion.
Adamu commended MESL for its cooperation and commitment to improving electricity supply, expressing optimism that the project would be delivered within schedule.
The Chief Technical Officer of MESL, Engr. Cleber Romao Grisi, thanked TCN for granting access to the site and assured that the company would adhere strictly to the delivery timeline.
Other officials present at the handover included the General Manager (Business Development), Engr. Robert Bodam; General Manager (Transmission), Shiroro Region, Engr. Kabiru Suleiman; Assistant General Manager (System Electrical), Engr. Ebenezer Opadare; and Principal Manager (Transmission), Kainji Work Centre, Engr. Gbenga Akorede.
The project is expected to enhance grid stability and improve overall power transmission efficiency in the country.
