Abstract

The efficiency of a given production is defined as a ratio between the incurred costs and the achieved result. Production by cogeneration, i.e. the production, in which the same primary energy source is used for the joint production of two different products - thermal and electrical energy, causes a specific problem in the distribution of operating costs between the two generated products. Since there are usually significant fixed costs common to both products and there is no way to determine on the facts what proportion of these costs are attributable to one product or the other, the allocation of costs in such a multi-product enterprise is always arbitrary. The result is that different methods can be used to randomize these costs. The article examines the various methods and compares the results obtained at the Lukoil Neftohim TPP.

Keywords
