The Transmission Company of Nigeria has announced the addition of 600 megawatts to the national electricity grid following the completion and commissioning of a major transmission infrastructure project in Edo State, a development expected to improve power evacuation and strengthen electricity delivery across the country.

The Managing Director and Chief Executive Officer of the Transmission Company of Nigeria, Sule Abdulaziz, disclosed this on Thursday during the official commissioning of the Ihovbor/Benin and Ihovbor/Ajaokuta 330kV Turn-In-Turn-Out Transmission Line Project in Edo State.

According to Abdulaziz, the project represents another significant milestone in the Federal Government’s ongoing efforts to reinforce the nation’s transmission network and improve the stability of electricity supply nationwide.

He explained that the newly completed transmission infrastructure would enable the country to evacuate more bulk electricity generated from the Ihovbor Transmission Substation to distribution load centres across Nigeria.

The TCN boss said the project involved the strategic connection of the existing Benin/Ajaokuta 330kV transmission line to the Ihovbor Transmission Substation, thereby creating two additional transmission routes aimed at enhancing operational efficiency and network reliability.

“This project involves the strategic linking of the existing Benin/Ajaokuta 330kV transmission line to the Ihovbor Transmission Substation, creating two new transmission routes with a total length of 14 kilometres,” Abdulaziz stated.

He further noted that the completion of the project had significantly increased the operational flexibility of the transmission network while also improving the resilience of power delivery within the Benin transmission corridor.

“With the completion of this strategic project, we have increased the operational flexibility of the transmission network and strengthened the resilience of power delivery within the Benin corridor through this connection to the power plant,” he added.

Abdulaziz stressed that the importance of the project could not be overemphasised, particularly as it enhances TCN’s capacity to evacuate electricity generated by major power plants, including the Azura Power Plant and the Niger Delta Power Holding Company facility.

“The importance of this project cannot be overstated. It grants TCN the ability to more efficiently evacuate power generated by the Azura Power Plant and the Niger Delta Power Holding Company plant,” he said.

Industry stakeholders believe the development could help reduce some of the transmission bottlenecks that have long hindered efficient electricity distribution in the country.

Nigeria’s power sector has for years struggled with inadequate transmission infrastructure, despite improvements in generation capacity. Experts have repeatedly pointed out that although some generation companies are capable of producing more electricity, limitations in transmission capacity often prevent generated power from reaching consumers effectively.

The newly commissioned project is therefore expected to ease pressure on the national grid and improve the wheeling capacity of TCN, especially in the South-South and other connected regions.

Energy analysts say the additional 600MW to the grid could contribute to improved electricity supply for homes, businesses and industries if effectively distributed through the downstream power network.

The commissioning ceremony also highlighted ongoing investments by the Federal Government and stakeholders in expanding the nation’s electricity infrastructure as part of broader reforms targeted at boosting economic growth and industrial productivity.

Observers noted that improved transmission infrastructure remains critical to achieving stable power supply in Nigeria, especially as demand for electricity continues to rise due to population growth, urbanisation and industrial expansion.

The Ihovbor Transmission Substation plays a key role in Nigeria’s power architecture because of its proximity to major generation plants in the region. By strengthening the connection between generating stations and distribution networks, the new transmission lines are expected to minimise system constraints and enhance grid stability.

The project is also expected to support future expansion plans within the power sector, including the integration of additional generation sources into the national grid.

Stakeholders at the event commended the Transmission Company of Nigeria for pushing forward with strategic projects aimed at modernising the country’s transmission system despite operational and funding challenges confronting the sector.

Many Nigerians, however, continue to hope that improvements in generation and transmission capacity will ultimately translate into more stable electricity supply and reduced outages nationwide.

The latest announcement by TCN comes amid renewed efforts by the government to address longstanding challenges in the power sector and improve energy access for millions of citizens and businesses across the country.
