Pivot Engineering, technical partners upgrade deliver substations

Pivot Engineering Company Limited (PECL), a member of Honeywell Group, and its partners, including Siemens Transmission & Distribution SAS France and Siemens Nigeria Limited, have completed the power transmission projects for the upgrade of substations in Ajah, Lekki and Alagbon (Ikoyi) areas of Lagos to further ensure reliable and quality power supply to the state.

Upgrading of the three substations is part of the National Integrated Power Project (NIPP) intervention of the Niger Delta Power Holding Company (NDPHC), itself an initiative of the Federal Government of Nigeria, to add significant new generation capacity to Nigeria’s electricity supply system together with associated transmission, distribution and gas supply infrastructure.

Speaking on the project, Bayo Oluwafemi, the GM Projects of Pivot Engineering, said that the three substations upgraded “are very unique and among the few Gas Insulated Switchgears (GIS) Substations embarked upon by NDPHC as majority of the other substations have AIS (Air Insulated switchgear).”

“These substations would also bring about economic benefit by strengthening the national power grid to enable the government achieve its long term target of realizing 10,000MW”, he added.

Before the NDPHC intervention, Ajah Substation had installed capacity of 330KV 300MVA. Ajah Substation has been expanded under the NIPP initiative by the addition of 330KV 150MVA and 132KV 100MVA. The old 132KV GIS system was extended and new 330KV GIS System was installed at Ajah.

There was no Substation at Lekki before the NDPHC intervention. As a result of growth and expansion in Lekki, NDPHC contracted the Pivot-Siemens Consortium to construct the new Lekki 132/33KV 120MVA GIS Substation to also provide reliable, quality power to Lekki axis of Lagos state.

The scope of work included but was not limited to the installation of new 132KV GIS System and 33KV indoor switchgear to evacuate power though 8Nos 33KV feeders.

The Alagbon Substation was built in the 1980s and in need of repair before NDPHC commenced its upgrade. This substation feeds Ikoyi axis of Lagos state. It had 2 x 60MVA 132/33KV AIS Mobile Substation installed by TCN. However, to improve the power supply in Ikoyi, Lagos the Alagbon Substation has been upgraded by NDPHC to a 330KV substation.
