Project summary

Development of wind energy is of special importance to Georgia. There are no recoverable oil and gas resources in Georgia and its all utilized organic fuel is fully imported. It places a heavy burden on the economy, industrial development and weakens the energetic security of the country, its capabilities to fully meet its subjects’ demand for energy in the quantity and quality, required for sustainable socio-economic development. At the same time, Georgia has extensive wind power resources, which will allow to significantly improve the country’s power engineering situation.

Usage of wind energy will have a beneficial effect on the environmental situation in the entire South Caucasian region.

The aim of this project is to conduct a micro-scale investigation of the wind energy potential within inpidual terrain structures using regional estimates of wind energy potential, carried out during the implementation of G-539 ISTC project.

There are some premises for the project’s successful fulfilment:

  • a well-developed net of meteorological stations is functioning on the territory of Georgia and series of regime observations within many years (20 – 40) are available for using them in the project;
  • the head organization – Wind Energy Scientific Center “Karenergo” – has at its disposal all necessary wind measurement apparature, computing technics and special software means, obtained in the process of ISTC project G-539 entitled as “Investigation of wind energy resources of Georgia and creation of Wind Energy Cadastre” fulfilment. The numbers of the executives is defined by carrying out of a great volume of field works in several sites simultaneously that has been told on the project estimate cost;
  • the project’s main participants have a necessary qualification and experience in the job, concerning such branches as climatology and Wind Energy, have the use of modern methodology of wind regime measurements, algoritmization of statistical tasks, compilation of specialized programs. A successful fulfilment of the work according to the TASIC program, a contract work with NREL # ACE 8-18647-01 USA and ISTC project G-539 “Investigation of wind energy resources of Georgia and creation of Wind Energy Cadastre” give evidence to it.

Estimation of the wind energy potential reduces to determination of the average specific power of wind flow typical of large territories, the so-called “regional estimates”. It allowed to pide Georgia into districts by wind flow specific power and revealed the most perspective ones. However, these estimates are not sufficient for development of specific projects of Windfarms and making energy production prognoses. It is known (and this is confirmed by the conducted investigations) that climatic conditions, in particular wind climate, while being stable, on the average, on the large territory, quickly varies in small areas under the influence of the relief's local peculiarities. Thus, siting is required, which means micro-scale investigations of wind climate in conditions of separate relief formations. Noteworthy is that the investigation methods, in general, are similar in both cases, however, siting requires more detailed data which may be obtained through expressmeasurements of wind regime in selected areas and analysis of random velocity field by the method of sections. The period of such measurements is to be about two-three years (which determines the period of the project). The data of such measurements, together with regional estimates, will allow to obtain statistically stable assessments of wind climate within limited territories, where building of large Windfarms is possible.

The results, obtained under the proposed project, will form a scientific-informational foundation for development of business plans, attraction of investments for building of Windfarms in Georgia and are of great commercial interest from this viewpoint.

Also, the developed interpolation methods of wind regime measurements in the mountain relief conditions, using numerical models, calculations of velocity distribution laws and vertical profiles may be of scientific interest in themselves, all the more so since they will be confirmed by field experiments.

All results will be referenced with necessary commentary and formed as a published edition.

The project's main participants formerly connected with weapon themes will be able to use their knowledge and abilities for peaceful goals resolution regarding energetics and ecology and to make a contribution in a decision of the problem on the climate global getting warmer.

The recent project' ll allow its participants to tighten up existed links and to establish new ones with foreign colleagues. The experience got in the process of the work on the project will give an opportunity to its participants to carry out the same commercial-based investigations for the other countries. Thus, project is in accordance with ISTC objectives.
