Project start
On the 29th of April 2004, the Bulgarian Prime minister Simeon Saxcoburgotta
announced the beggining of the construction of Hydro power project Tsankov Kamak.
Hydro power project Tsankov Kamak is situated on Vacha river, which is on of
the big Bulgarian rivers. At the present moment there are six hydroelectric power
stations on the river Vacha with total installed power of 446 mWt and annual electric
production of 543 GWh. The water-power sustem is being built in the middle section
of the river. The project comprises of:
-
Tsankov kamak dam with total volume of 111 000 000 m³. The dam is an arch concrete
dam with double curvature. In the left and the right bank the dam ends with gravity
blocks and its arch part is completely symmetrical. The maximum dam height is
130.5 m, dam crest elevation is 688.5 m and the highest blocks are founded on
elevation 558 m. Dam length along the crest is 468 m, and the chord is 345 m.
The volume of the concrete to be inserted isto the dam is 465 000 m3.
-
Hydropower station Tsankov kamak with capacyty of 80 MWt and average annual
power production of 185 GWh
The terms for completion of the project is 5 years. The hydropower plant will
be a property of the Bulgarian national Electric Company - NEK AD.
The total value of the project is 220 million Euro. ìèëèîíà Åâðî. It is financed
by export and commercial credits without sovereign guarantee. The financing contracts
are signed on the 14th of November in Vienna. The half of the sum (100 million Euro) is covered
by an export credit, guaranteed by the Austrian bank Oesterreichische Kontrolbank
Aktiengellschaft (OeKB). The rest of the sum is covered by commercial credit. The
overall financing includes the following participants:
- VA TECH Finance - Leading bank - organizer;
- Bank Austria Creditanstalt - Bank organizer of the export credit amounting
100 million euro with the following banks: Fortis Bank, Raiffeisen Zentralbank,
Societe Generale;
- Credit Suisse First Boston - Bank organizer of the commercial credits;
Oesterreichische Kontrolbank Aktiengellschaft (OeKB) provides the export insurance,
covering the political and the commercial risks of the export credit ammounting
100 million Euro. OeKB also provided insurance of four additional export credit
agencies: Coface from France; Hermes from Germany; EKN from Sweden and Egap from
the Czech Republic.
The exploitation of hydroelectric power plant Tsankov Kamak will improve the
function of the other hydroelectric power plants on Dospat-Vacha cascade. The
construction of the missing middle section of the cascade will contribute to the
complete absorption of the present hydroelectrical potential of Vacha river.
The high level of manoeuvring of the hydroelectric power contributes to the enhancement
of the energy efficiency during the exploitation of the electrical production
powers in the energy system.
Regarding this the hydroelectric power plant Tsankov Kamak will cover peak electric
charges and ensure electric reserves in case of dropped off main powers.
In the period of construction of the hydro power project will be engaged work
force from Bulgarian construction companies. The full capacity of the construction
works foreseens the opening of 700 new work places. After the completion of the
construction works, 50 workers and specialists of the adjasent cities will be
hired for the needs of the hydroelectric power plant. This will have a strong
social effect leading to lowering of the unemployment in the region.
The construction of hydroelectric power plant Tsankov Kamak will stimulate the
development of the regional infrastructure and communications. A significant role
will take the reconstruction of Devin-Mihalkovo road. The project is included
in the regional program for development. The project will stimulate the construction
of new purification station for the town of Devin as well as new dung-hill.
In nation-wide scale the construction of the hydroelectric power plant will influence
different economical sections, connected with the production of electrical equipment,
transportation and servicing. The construction sector of the economy will be stimulated
by orders for cement, steel and other construction materials. New conditions for
fish-breeding and tourism in the town of Devin will be developed.
There are no residential buildings and agricultural equipment in the area of
Tsankov Kamak dam, which means that the realization of the project does not require
migration of the population.
