The electrical problem in Palestine

In Palestine, the weakness of public grids does not allow the supply security at critical facilities such as hospitals, schools and universities and research nor the successful development of SMEs.

Instead of using only fuel through diesel generators to mitigate these shortcomings, the project addresses a solution to reduce the use of this expensive and polluting medium by installing solar photovoltaic systems with intermediate storage subsystems connected to generators.

When grid is available, photovoltaic energy will be injected. In case of grid interruption (a common problem in these countries), the power supply will be guaranteed by the PV system, along with the diesel generator if the photovoltaic generation is not sufficient (under low irradiance, overloading, etc.). In addition, an intermediate storage subsystem must guarantee the continuity of power supply variations generation of very short term, or during the period of implementation of the diesel generator.

These PV systems will have an impact on reducing domestic electricity bills because, in general, in these countries the price of electricity is subsidized by the government. Consequently, if the total consumption of electricity is reduced, the electricity bill will also be reduced.

It is also expected that this solution will reduce the use of diesel fuel, as the weakness of the network forces people to ensure supply using diesel generators. 

CO2 emissions could also be reduced, since the amount of CO2e (CO2 equivalent) caused by electricity generation nearly doubles the European average (about 0.83 kg CO2e per kWh), as most of the electricity production in the three countries is obtained through the conventional generation (fuel, oil and gas).

Moreover, with the introduction of these systems it is expected to increase the capacity of SMEs, as the lack of infrastructure does not allow the industry to increase its contracted power. The use of these PV systems will ultimately enable companies to increase their power limit letting them increase its industrial production and, consequently, improve the country's development.
