Sažetak
By technological development generating units in the power system are getting bigger and bigger. Even open electricity market, for being more competitive, force units to be as efficient as possible. When we talk about hard coal fired thermal plants, the most often unit size constructed in recent time is between 600 MW and 800 MW. For some countries in the region, it is more than 10 to 15 percent of the peak demand, what is acceptable, or proper size for the biggest unit in the system. This article is dealing with problem of fitting 500 MW thermal block Plomin C, fired by imported hard coal, in the Croatian power system. The block should be constructed on the existing power plant location in the Plomin bay. The expected number of hours per annum of the using maximal capacity of the Plomin C (capacity factor) has been analysed, taking in to account existing power plants in the Croatian power system (base, peak and intermediate), hydrology conditions, wind power. Also planned power plants that should be constructed according to official Energy Strategy, should be considered. The target of this article is to analyse possibilities of fitting this 500 MW block, to see what kind of problems can arise, in such relatively small system with peak demand around 3000 MW, and minimum load around 1300 MW. Some solutions for the off peak hours (particularly for the hours with the lowest demand) are suggested, when some of the base load power plant should decrease output power or even be shut down, when very wet hydrology and good wind conditions occur.
