Audit and Evaluation of the Nigerian Power Grid System, for the identification of sources of transmission losses
Client: Transmission Company of Nigeria (TCN)
The project involved the inspection and assessment of power plants in the Nigeria where power is injected into the grid, and the transmission substations where the Distribution Companies and the Eligible Customers extract power from the grid. It also involved assessing the availability of the relevant metering systems at the Trading Points, and the measurements of the primary and secondary currents of the CTs to check for consistency between the nameplate CT ratio and the actual ratio. The wiring of the meters was inspected to confirm consistency with the specifications.

Development of Electricity Infrastructure Master Plan for Ekiti State of Nigeria through Exenergia Consulting Limited, as the Principal Consultant
Client: Ekiti State Government
The objective of this project was to assist Ekiti State Government obtain data required for its power supply infrastructure planning. Emtech assisted the Principal consultant (Exenergia) for the project, to determine the power supply need of the State, giving the present load demand and the projected load demand from the economic and social development plans of the state, for the next ten years. With the annual demand of power supply for ten years established, an audit of the existing infrastructure was conducted to establish the supply infrastructure gap along the value chain. The power generation gap, as well as the power transmission and distribution gaps were established. The necessary investments in power generation, transmission and distribution to close the established gaps were also identified.
