Partial or complete construction

Wind Business
During the last years the wind energy business
increased significantly its rates of
development, due to factors like 50% growth of
purchase price of generated energy and other
favorable conditions, given in the Law for
energetic in 2003.
The wind is free and the operative costs are
low, because minimum service personnel are
required. But the completion of such project is
a process, to which a very careful approach is
required in each phase and in the complex
engineering.
The advantages of the wind energy are numerous
and undisputable. Briefly they can be classified
in two main spheres – financial and ecological.
On one side the wind is free and inexhaustible,
and the exploitation costs of the wind
generators are almost reduced to zero. On the
other side the exploitation of the wind does not
lead to pollution and climate anomalies.

WIND
RESOUCES IN BULGARIA
The researches carried out show that there are
objective conditions for development of wind
energy in Bulgaria. The places, where there is
potential for wind farms are mainly near the sea
coast and places with altitude more than 1000m
and some other wind zones. In Bulgaria there are
199 meteorological stations which register the
speed and direction of the wind. The data
available from the last 30 year is a base for
composition of wind potential map. But it should
be pointed out that the mean wind speed is not a
representative value for assessment of the wind
as an energy source.
According to EU directive adopted in 2001 for
stimulation of electricity production from
renewable energy sources (2001/77/EC), the
member states are obliged to increase the
percentage of the electricity produced from
Renewable energy sources to 12% in 2010.
Currently in Bulgaria the electricity production
from renewable energy sources is stimulated by
special investment schemes, preferential tariffs
and systems for tradable green certificates.
According to art.21, par.1 of the Law for
Renewable and alternative energy sources and
bio-fuels
(http://www.mi.government.bg/norm/laws.html?id=213022)
and art.4, par.3 of the Ordinance for regulation
of the electric energy prices, the State
Commission for energy and water regulation
annually up to 31 March defines preferential
process for sale of electric energy, produced by
renewable or alternative energy sources,
excluding the energy produced by water power
stations with installed capacity more than 10
MW. Art.21, par.2 of the Law for Renewable and
alternative energy sources and bio-fuels
determines the preferential price of electric
energy produced by renewable energy sources to
be 80% of the average sales price for the
previous calendar year for the end suppliers
plus an addition determined by the Commission
depending on the type of the primary energy
source according to the Ordinance for regulation
of electric energy prices.
