There are two major renewable energy sources in Bosnia and Herzegovina: hydropower for electricity production and biomass for heat production.According to the CETEOR study, the estimated potential for the renewables is as follows: HydropowerThe theoretical potential for hydro potential in the country is estimated at 8,000 MW. With an installed capacity of 2052 MW (53% of electricity generation), hydropower is already highly significant in Bosnia and Herzegovina, although its potential is far from being fully exploited yet (37% of economic potential). The majority of the installations are more than 30 yrs old. Average precipitation in the country is 1250 mm/m2, the third highest in the region after Montenegro and Slovenia, although these volumes of water are not evenly distributed, neither spatially or temporally. Small hydro is regarded as the most promising source of new renewable energy for the country. Currently, there are ten small, mini or micro hydro plants in operation, with a total capacity of 31 MW. Another two plants are under construction (1.8 MW) and 20 more are planned, totalling a further 28 MW.Wind energyTotal wind potential in the country is estimated at 2,000 MW, of which approximately 900 MW is exploitable. There are promising wind values shown by measurements taken before the war for the region of Trebinje through Mostar to Bugojno, and more up-to-date measurements from meteorological stations and airports which reveal large areas of the country with wind velocities of over 10 m/s at a height of 10 m on 150 days in the year.Biomass energyThe potential is present for biomass energy to provide 14% of the total energy supply, versus the actual 6.5% of the total energy consumption. An estimated 34.5 PJ of energy is available as biomass resource in the country, predominantly firewood, grain residues, and residues from log processing. Potential co-generation amounts to 410 MW of heat and approximately 200 MW of electricity per annum, with an additional 600 MW of estimated thermal capacity being available from wood wastes. The potential of biogas from the agricultural sector as an energy source has also been recognised, although no in-depth study has currently been conducted. Near Sarajevo, a landfill gas plant with a 350 kW generator has been built with Austrian support; its capacity is due to be doubled in the near future. The electricity is fed into the urban grid. However, remuneration for electricity generated from biomass sources is low in Bosnia, currently standing at 3.81 € cents/kWh.Geothermal powerGeothermal potential has been estimated at 33 MWt. Thermal plants of 50 – 100 MW have also been proposed as a potential power source for district heating programs.Solar energyBosnia and Herzegovina, in common with other nations of the former Yugoslavia, has a good solar regime. Theoretical potential has been estimated at 74.65 PWh per annum, with solar irradiation figures of 1 240 kWh/m²/yr in the north of the country and up to 1 600 kWh/m²/yr in the south. Despite this, current utilisation of solar power is low in the country.
