The Power Plant
The Nesharim power plant is a modern and advanced power station, using combined cycle technology, with an output capacity of approximately 120 MW.
The plant comprises three electricity generation units, including two gas turbine units, each with a capacity of 48 MW, in addition to a steam turbine unit with a capacity of 25 MW.
Combined cycle technology makes use of the thermal energy that is inherent in the exhaust fumes of the gas turbines, in order to create steam. The steam that is created in the heat exchange boilers operates the steam turbine, thereby increasing the capacity and efficiency of the plant, by generating more electrical energy from the same amount of fuel.
The gas turbines are LM6000PF aviation turbines produced by GE. The aviation turbines are based on an engine that serves to power jet airplanes.
The turbines are consequently characterized by rapid ignition and load modification times, thereby offering the plant the maximum flexibility required given the regulatory environment under which the plant operates. The steam turbine is a SST300 model, manufactured by Siemens.
For various environmental protection and natural resource planning considerations, the steam condensation at the plant is done using an air cooled condenser, which realizes considerable savings in water and wastewater, as compared with a wet method condenser.
The station is also outfitted with two chillers possessing a total capacity of approximately 3800 tons of refrigeration, that refrigerate the air entering into the gas turbines, thereby ensuring the full capacity of the gas turbines, even during the numerous days of hot weather in Israel, when gas turbines lacking refrigeration lose a considerable proportion of their output capacity.
In a manner that is unique to the plant, the brine that is created during the generation of electricity – from the cooling towers and the non-ionized water production system – is transferred to the nearby cement plant and is integrated in the cement manufacturing process, thereby realizing a significant environmental advantage, by saving both water and wastewater treatment.
Mashav Energy served as the plant’s EPC contractor and was responsible for the planning, purchasing, construction, operation and running-in of the plant.
In the establishment of the plant, the company employed local contracting companies, including Omer Engineering, Elkayam, Metal Industries, YH HaGiva, Issa Huri Metal Industries Ltd., Afcon Installation and Services, Afcon Control and others.
The operation and maintenance of the plant is performed by Mashav Initiating and Development.
