In establishing such data like load density, demand factor and load factor, it was necessary to conduct a research so as to ascertain the parameters in an existing industry, where Warri refinery was taken as a case study. The research came out with the following useful data for: Load density = 12.8 VA M 2, Load factor = 88.5%, Demand factor = 24.4%.
