The Bulgarian energy sector is undergoing a major overhaul.
Improvement of Energy efficiency
Construction of new
EU directives for at least 20% renewable energy by
the year 2020
Nuclear energy in Bulgaria
Bulgaria has two nuclear reactors generating about 35% of its electricity.
On June 11, 2010, the Bulgarian government announced that it would freeze indefinitely the planned construction of the Belene nuclear power plant because it was uncertain when the investment would be returned. Five months later, on December 2, a non-binding memoranda of understanding was signed between NEK EAD, Rosatom, Altran and Fortum, setting up a 6.3 bln. euro price on the power station, after months of unsuccessful talks on the cost and redeemability of the project itself. Further disagreement and the persistent demands of the Bulgarian government to lower the cost under 5.0 billion euro led to the termination of the project in March 2012.
Hydro energy in Bulgaria
Bulgaria is actively working on the development of its hydrological sources
in an effort to limit the dependence on foreign fuel imports. Around 63
small and micro Hydro Power Plants were located on the National Energy
Company's (NEK) property, most of which have been privatized.
Wind energy in Bulgaria
The European Union has set a directive requiring its members to to produce
at least 20% of their electricity by environmentally clean and renewable
sources. Certain areas of Bulgaria have favorable wind conditions and
investment in wind power generators are showing good returns.
Solar energy in Bulgaria
A sizeable portion of Bulgaria's land area receives medium levels of solar
Biomass in Bulgaria
There is good potential for utilizing biomass as an energy source in
Bulgaria. While information regarding the use and potential of biomass has
been limited, there have been recent developments through pilot projects and
preliminary evaluations that begin to highlight Bulgaria's full potential.
Results have appeared promising, although a lack of project funding has
hindered the forward progress of this resource.
Geothermal Energy in Bulgaria
Bulgaria has a sizable reserve of geothermal energy and is rich in low
enthalpy geothermal waters. The country has been utilizing approximately 30
percent of its total potential, or about 107.2 MWt producing some 1.637 TJ
of energy per year, for use in space heating, greenhouses, drinking water,
and for balneology purposes (Geothrmie, 2000). At the present there are no
geothermal reserve sites that generate power.
