“…When TPP operates in the heating mode, the EFSC is significantly dependent on the chosen method of fuel consumption separation between electric and thermal energy [35]. On average, for TPP based on STU, depending on the approved method, the difference can reach 60 e.f.gr/kWh [36]. Calculations have shown that for TPP based on CCGT-450, the difference in EFSC can reach 20 e.f.gr/kWh depending on the approved technique.…”

The percentage of heat pumps used in thermal power plants (TPPs) in the fuel and energy balance is extremely low in in most countries. One of the reasons for this is the lack of a systematic approach to selecting and justifying the circuit solutions and equipment capacity. This article aims to develop a new method of calculating the maximum capacity of heat pumps. The method proposed in the article has elements of marginal analysis. It takes into account the limitation of heat pump capacity by break-even operation at electric power market (compensation of fuel expenses, connected with electric power production). In this case, the heat pump’s maximum allowable capacity depends on the electric capacity of TPP, electricity consumption for own needs, specific consumption of conditional fuel for electricity production, a ratio of prices for energy resources, and a conversion factor of heat pump. For TPP based on combined cycle gas turbine (CCGT) CCGT-450 with prices at the Russian energy resources markets at the level of 2019, when operating with the maximum heat load, the allowable heat pump capacity will be about 50 MW, and when operating with the minimum heat load—about 200 MW.

Energy saving at any enterprise is an urgent problem associated with high expences for energy carriers and a constant increase in their cost. The aim of the study is to modernize the energy system of one of the poultry factories in the Vologda Oblast in Russia in order to reduce electricity costs. Modeling methods for a comprehensive assessment of possible options were usedas well as an experiment that showed that the most effective way to reduce electricity costs was to upgrade the energy system based on “small generation” using traditional fuels. The modernization allowed the poultry farm to produce up to a third of its own electricity with the help of mini-CHPs annually, and to keep the cost of the generated kW⋅h three times lower than the network. The experience of modernization of the energy system of a poultry farm in Russia has confirmed the possibility of joint use of PTL-6(10) and a steam turbine generator at the enterprise. The paper will be useful to researchers and energy specialists who are looking for ways to save energy on a poultry farms.
