The promoter of International Imperial Business City (IIBC), ChannelDrill Resources Limited, has plans to build an independent electricity project to power the development.
The IIBC is a planned smart city located on a 200 hectare expanse of land in Ikate Kingdom to be reclaimed from the Lagos Lagoon.
The city is designed to have uninterrupted power supply from clean energy sources, according to the Managing Director of ChannelDrill, Mr. Olufemi Akioye, who explained that the IPP in the smart city would ensure it is self- sustaining. “Besides, the use of IPP within the city will ensure that there is no need for the use of generators by inhabitants of the city, leading to clean energy.”
Also included in the city’s master-plan is the construction of a waste treatment plant that would produce methane for use in the production of more electricity or cooking gas. “Electricity will be available on 24/7 basis; cooking gas will also be piped into each building thereby eliminating the usage of gas cylinders in the city,” Akioye explained.
He said, “Due to power supply intermittency, the developers have assumed that Lagos does not have capacity to uptake the new demand levels of the island. Therefore, a new intake substation on the Island would be supplied directly from an existing substation on the mainland via a subsea cable.”
He said this would act as a secondary supply to the city and could potentially be used to export surplus electricity to the existing Lagos distribution network.
Akioye said exhaust gasses from the generators used in the IPP would be treated by a dedicated gas cleaning plant to ensure that fumes released into the atmosphere complied with international standards. “Secondary power will be generated by alternative sources such as waste to power plants, while the fuel that is, liquefied natural gas (LNG) will be supplied to the city via barges. Fuel will be pumped into bulk fuel storage bays via pipelines from the coast. Bulk storage feeds into a treatment plant before entering generator supply streams,” he explained.
He said, “The infrastructure consultants to the project, Mott MacDonald Limited, London, United Kingdom, are also banking on past project experience on past Master Plans that were executed in climatic conditions similar to those of Lagos to estimate power density figures.”
He said this would be calculated for each load zone based on land allocation. “We are aware that air-conditioning is a large element within power demand in a highbrow area like the IIBC, so preliminary load estimate per plot is 100MVA.”
