The efficient use of electrical energy, energy conservation and electrical load management are not in a better condition in Palestine or in Nablus electrical network. In this thesis we tried through analyzing and evaluation of the energy consumption situation and by performing energy audits for several energy consuming sectors in Nablus electrical network, to prove that there is a good opportunity to save a considerable amount of consumed electrical energy. In addition, this study tries to find solutions to decrease the peak electrical demand of Nablus electrical network as the peak demand of the network is nearly equal to the available maximum capacity of the supply so as not to reach a situation that the electrical supply will be cut on consumers. It was showed that there is an opportunity to save a considerable amount of electrical energy if energy conservation measures were implemented in water pumping sector, residential sector and street lighting sector. The total savings in electrical energy in all studied sectors in this thesis is around 14,860,269 kWh/year, associated with an investment cost of 15567303 NIS, and SPBP of less than two years. The study also showed also that by implementing energy conservation measures and applying applicable load management techniques in the studied sectors, the peak demand of Nablus electrical demand can be decreased by 4.7%, and this percentage can be increased by applying a new electrical tariff structure.
