Potential wind and solar power resources in Altai Krai

An important advantage of renewed power resources is almost inexhaustible potential and ecological purity. Prospects of research are connected with sharp power deficiency in Altai Krai and presence of a large number of settlements without centralized power supply. Use of renewed power resources can sharply cut the expenses of budgetary funds on delivery of fuel for diesel electric power stations, increase the supply stability of electricity and heat for the population. Farmers, small and medium businesses, tourist camps and other recreational objects can become wind power consumers in the territory of the region. The research is to estimate the potential wind and solar power resources of Altai Krai. To determine the wind and solar energy potential of the territory a detailed study of its climatic conditions defining the wind and solar modes is carried out. By the result of the analysis of the wind mode and of wind stream specific capacity the southwest and northwest areas of Altai Krai are optimum for constructing wind power stations of small and average power, the northeast area - for stations with small power. In other areas where the average annual speeds of wind are less than 3.5 m/s their installation is unprofitable. Studying of radiating characteristics of the climate and cloud mode of the territory has shown an increase in solar power resources from the northeast to the southwest of Altai Krai. Three zones with various potential solar power resources are allocated: 1) more than 1300 kW^h/m , 2) 1200-1300 kW^h/m , 3) less than 1200 kW^h/m . In all three zones solar power systems of average and small sizes can function constantly. The territory division into districts has shown expediency of use of solar radiation as an additional energy source for the population. Effective work of solar batteries or solar installations of other types lasts from March till September. Use of independent solar and wind power installations and storages that provide long-term accumulation of energy is most perspective. To specify the operating mode of wind and solar power stations the list of indicators should be considerably expanded. For detailed estimation of potential renewed resources additional researches are necessary to examine the microclimatic features of the areas.
