One of the limitations in the application of renewable energy sources is the intermittency and variability in its supply. This characteristic has attracted many researchers and stake-holders to focus on the application of different types of hybrid energy technologies with storage systems to improve in the efficiency of the supply and dispatch ability of the system. The application of hybrid energy technology to generate heat and electricity is very popular nowadays and sustainable in the supply of energy for on-grid and off-grid services. The sizing of the hybrid energy supply is paramount to saving energy and meeting the energy demand at all time. This research work involves an analysis for sizing hybrid energy supply integrated with battery storage to meet the energy demand for 3-bedroom, office, sports and school building. Merit modelling tool was applied for the demand and supply matching and analysis of the various chunks of technologies of PV, WT, CHP and generator were carried out based on the suitability to achieve the best matching. The results show that hybrid systems with output capacities of 2.96 MWh, 203.15 MWh, 1.38 MWh and 2.14 MWh were used to meet the energy demands of 3-bedroom, office, sports and school buildings. The office building energy sizing was achieved with a match rate of about 90% with no energy deficit. However, surplus energy of 34.2MWh was recorded. The 3-bedroom, sports and school energy sizing were achieved with less than 1MWh of energy surplus or deficit and a matching rate of about 60%. For future study, the performance of the identified energy technologies can be verified using an integrated building performance simulation tool to ascertain its feasibility.
