The medium voltage network in Ramallah, Al-Berih and Beitunya is to be studied and analyzed to find out its weaknesses, and provide scenarios for resolving these weaknesses. PowerWorld Simulator were used to simulate real data collected from the SCADA system of the company, the output of the simulation highlighted two main problems, overloading and relatively high technical losses. Conservation measures were suggested in order to resolve the problems highlighted during the simulation, these measures can be summarized in upgrading the transmission lines to ACCC, reconfigure part of the medium voltage network, reducing neutral current in low voltage network, and replace the power transformers with high efficiency power transformers. The suggested measures then were examined using the simulator to simulate the improvements expected after applying the improving measure. Also, financial analysis of energy management measures in Ramallah electrical network was performed over all the suggested measures, which led to approving the first three measures and rejecting the fourth one. The financial analysis showed savings potential of about 15 million dollars during the life time of the project which is 15 years.
