Structure of JSC ELEM

Thermal power plants

Thermal power plants are a priority in the power system of Macedonia. They cover 81% of the production of electricity in JSC ELEM. REK Bitola has the largest thermal capacity with its three units Bitola 1, 2 and 3, with a net average annual production of 4.400 GWh. Coal is the main fuel in REK Bitola. The composition of the thermal system in the Republic of Macedonia includes also REK Oslomej with installed capacity of 125 MW and net average annual production of 500 GWh. Coal is also the main fuel in REK Oslomej.

Hydro power plants

The total installed capacity of hydro capacities is 553,6 MW, or 40% of total capacities of JSC ELEM. In JSC ELEM there are eight hydroelectric plants, two are running water type, Raven and Vrben and six accumulative, Vrutok, Shpilje, Globochica, Tikvesh, Kozjak and Sveta Petka. Of the total electricity production in JSC ELEM the hydro production provides about 19%, primarily to meet the daily variations in electricity consumption and providing system regulation services, thus providing greater flexibility and availability of the power system.

Wind power plants

In February 2014 completed the construction of Wind Park "Bogdanci", the first such facility in the Republic of Macedonia, which will use wind as the driving force for the production of electricity. Rising and installation of wind turbines on site Ranavec in the Municipality of Bogdanci ended on February 20, with which the most difficult phase of the construction, which lasted 76 days was officially completed.

At the end of March a coordinated operation of the three energy companies ELEM, MEPSO and EVN -Macedonia was conducted for connection of the wind park to the electricity grid through substation Valandovo. This endeavour created the necessary prerequisites to begin testing the complete equipment through trial production of electricity that began in early April when the first kilowatt-hour were delivered to power system of the Republic of Macedonia.

The turbines are produced by Siemens – Denmark and are among the best in their class. The installed capacity of each is 2.3 MW, tower height is 80 meters and the diameter of the rotor blade is 93 meters. The Wind park Bogdanci is expected to provide at least 100 GWh renewable energy annually. Simultaneously, they will increase the installed capacity for 36,8 MW. This project will increase the share of renewable sources in JSC ELEM, which is another indicator for the care of the company for the environment.
