Energy Optimization at Datacenters in Two Different Locations of Nigeria

Abstract

Two areas within the nation (Nigeria) were chosen for the energy optimization of their Datacenters. The evaluations of combinations of different specific energy options were used to determine the least-cost energy pathway for the optimization of each Datacenter's power. The optimization approach conducted was a sequential search for a possible option and combinations of grid supply, diesel generator, wind turbine and solar photovoltaic cell power generation. The results show that, grid is the best choice economically, because it attracts the least cost but the problem is that, the grid is not reliable and not efficient within the nation. From an environmental perspective there were significant benefits in using Hybrid So- lar-Grid power. It was observed that the diesel generator is out of place looking at the huge amount involved. From the results, Datacenter could save (9,731kg; 8,536kg) of CO2 emissions annually in Abuja (FCT) and Nkanu-West (Enugu State), re- spectively by removing backup Diesel Generators and by using Solar-Grid as a power source .
