Energy and Capacity Saving Potential in the Residential Sector of Oman

The substantial rise in Oman's load in recent years prompted researchers to investigate ways to reduce the construction of new power plants. Reducing the electricity consumption during the peak hours will provide the flexibility to lower the need of the generation units to be added on the system. This paper aims to find out the energy saving potential from the residential sector of Oman, specifically Main Interconnected System (MIS) load. Usually, the annual report circulated by the Authority for Public Service Regulation (APSR) provides the statistics of demand consumed. It states that about 45.2% accounts for residential consumption in 2021. A survey from different papers that emphasize the valuable contribution of energy savings from the residential sector is carried out. WASP-IV software is used to conduct the optimization generation expansion plan for a 20-year period. Another case is studied for the 25.2% decrease in home building consumption. The methodology is explained, as are the assumptions and constraints of the study. The results show a noticeable decrease in the total generation cost, environmental cost, and LOLP percentage for the energy saving case study compared with the base case.
