Abstract :

The meeting of the demand for electricity power that has been in an increasing trend in recent years is among the problems that Turkey should solve in short or middle term. One of the significant alternatives in solution frame is to get adavantage of hydro power potential effectively. The idea that small and middle scale hydrolic sources not having been taken into consideration until recently are utilized as river type power plants has come to fore.The total number of river type power plants under construction, project, plan and service is as many as 2000. Once completed, setting power is expected to be 25 thousands MW, average production to be 125 thousands GWh per year. One of them is Reşadiye Hidroelectricity Pover Plants (Reşadiye HES). Reşadiye HES made up of three seperate plants constructed on Kelkit Stream near Reşadiye subprovince of Tokat has 65 MW power and a capacity of 450 million kwk/year.River type power plants, in fact, are those with fewer negative effects on ecology and social balance compared with power plants as dam. However, a lot of power plants under project,construction and service are on the agenda as they have given or are likely to give harm to natural and social balance. It is also the case for Reşadiye HES. The power plants were constructed on the areas susceptible to erosions, nevertheless, water canals were constructed on steeps instead of through tunnels. Besides, natural vegetation has been damaged during construction. The biggest problem is experienced when water was directed to canals. The main reserve water decreases under limit in summer season which gives harm to the ecology of Kelkit Stream, mostly the plants on the banks. The investment was reacted by the local people and they quarrelled with the construction firm. The project not being based on scientific principles, various difficulties during construction, investment being excempt from ÇED report played important roles on this and such problems. To take Reşadiye HES sample into consideration will be useful before new HES projects are designed.
