HYDRO POWER PLANTS
The only renewable resource with energy, economic, and ecological parameters that are confirmed and proven worldwide is the hydro potential. Our country offers significant hydro potential. In JSC ELEM there are eight hydro power plants, of which two are running water type - Raven and Vrben and five are reservoir-water: Vrutok, Shpilje, Globochica, Tikvesh, Kozjak and Sv. Petka. The total instalment of the hydro plants amounts at 566 MW, that is 40% of the total capacities of JSC ELEM. Out of the total generation of electricity power in JSC ELEM, hydro generation supplies 21%, which primarily serve for satisfying the daily variations in electricity power consumption which results in greater flexibility and availability of the electricity power system. .
Hydro power presents a renewable energy resource and everywhere in the world it acquires attention due to its multi-purpose exploitation: electricity power generation, water supply, industrial watering, recreation, and fishing.
THERMAL POWER PLANTS
The largest part of the total electricity power generation in Macedonia is provided by MPC Bitola and MPC Oslomej, from the coal based in the mines of Suvodol and Oslomej. Coal is going to become an important energy source for our country. The development policy of Elektrani na Makedonija is based upon the principle of timely provision of exploitation reserves of coal and it continually and systematically performs activities for further explorations of the potential sites. We can strategically conclude that the future of the energy system in Macedonia lies in the established and in the potential reserves of coal. The biggest thermal plant is Bitola, with its three units – Bitola 1, 2 and 3, each with 233 MW. They provide 80% of the electricity power generation in our country. Coal with average caloric value of7.900 kJ/kg is the main fuel of MPC Bitola. Another unit in the thermal power system of Macedonia is MPC Oslomej with installed power capacity of 125 MW and an annual net-generation of 400 GWh. Likewise, coal with average caloric value of 7.900 kJ/kg is the main fuel in MPC Oslomej, as well. Thermal plants are a priority in the national electricity power system.
