- MakaleAçık Erişim2019Capacity Factor Analysis in Small Scale Hydropower Plants and a Practice Specific to Giresun
Serencam, Uğur
Energy is the fundamental element of social and economic sustainability in every aspect of life, from the smallest living body to large scale industrial facilities. In Turkey rapidly increasing industrial development process lead to extensive energy demand, which is met largely from imported fossil sources. Especially in recent years, as a result of increasing environmental awareness and economic and strategic reasons, a portion of the energy deficit is fed from, clean and reliable hydroelectric power plants with great importance. In our country, a total of 295511 GWh electricity was produced in 2017. About 41368 GWh (14%) of the total amount was generated by large hydraulic plants and 17082 GWh (5.78%) by small hydraulic plants. In this study, small hydroelectric power (SHP) stations are considered to reduce the increasing energy cost and for this purpose SHP in Giresun are analyzed leading to private additives in the capacity factor analysis. According to the results it is possible to conclude that thetime of power plant investment is shortened as the capacity factor increases in hydroelectric power plants.

Serencam, Uğur
It is well known that any kind of ordinary hydrometeorological parameter trend may have increasing or decreasing tendency systematically. Various methodologies are developed for possible trend identification such as the well-known Mann-Kendall test and recently Şen innovative trend analysis (ITA) approaches. The former has a set of assumptions, whereas the latter is almost without any restrictive assumption. The main purpose of this paper is to present precipitation and temperature trend behaviors by applying ITA in Yesilirmak drainage basin. Selected observation stations are mainly located at the Black Sea confluence region of Yesilirmak while few others at the middle and upper drainage basins. ITA provided visual inspection with quantitative trend slopes distinctively for low, medium, and high sub-levels with physical interpretations. Based on categorization, precipitation records have significant decreasing trends in low, medium, and high levels as an average − 3.4%, − 3.8%, and − 2.4%, respectively. In contrary to precipitation trend, and consistent to global expectation in climate change, temperature records have significantly strong increasing tendency along the basin. In sub-level of temperature, this strong trend tendencies are detected + 4.6%, + 4.8%, and + 7.2% from low to high ranges, respectively.

Serencam, Uğur
Turkey has many problems due to its increasing energy consumption and rapid economic growth. Foreign energy dependency adversely affects sustainable development of the country by hindering its economic development. Turkey has a yearly total 433 TWh hydropower capacity and 151 TWh yearly economical capacity. The electricity demand of Turkey will reach to around 420 TWh annually by 2020. Turkey had 521 operational hydropower plants with a total capacity of almost 24,000 MW in 2014. This corresponds to 34% of the total capacity. Within the first 8 months of 2015, 8 more hydropower plants came online with a capacity of around 1,240 MW. The share of hydro in power generation capacity went up by 1% during the first five months of the year reaching 35% from its previous 34% level in 2014.
