The history of decisions on creation of nuclear and metallurgical complex on the basis of the Kola nuclear power plant

Some reasons for the choice of directions for using electric and thermal energy of the Kola nuclear power plant located beyond the Arctic Circle have been presented. The regions of the country and their large-scale industrial productions based on metallurgical enterprises have been indicated; the electrical supply of these enterprises is implemented from the Kola NPP. The results of research of energy inputs for the production of a ton of steel and cast iron have been presented. It has been determined that the main direction of technological modernization in the steel industry is avoiding the use of organic fuels (particularly in coke-blast furnace production as the most energy-intensive) and its replacement with the technology of direct reduction of iron with hydrogen. As an alternative energy source for organic fuels the creation of a fuel-free nuclear-metallurgical electrified complex has been proposed. The principal scheme of the fuel-free nuclear-metallurgical electrified complex has been described, here the main novelty has a reducing gases preparation block giving the potential ability for creating waste-free process. It has been noted that this technology requires using high temperatures and solving technical problems related to heat resistance of constructions. Some examples of world research on the implementation of similar projects have been presented. It has been determined that the use of new technology will cause the need for optimization of power consumption structure due to the redistribution of capacity and electrical consumption between productions. The introduction of new technologies requires solving a number of problems on electric power supply and electrical equipment designing. It has been observed that on the Kola NPP large-scale reconstruction was carried out during the working period, it helped to increase its project capacity and extend the operation life. Nowadays the region has excess installed capacity that can be used to introduce new technology in metallurgy.

Results of the demand management project to ensure system reliability from the point of view of electricity consumers

In the Russian Federation an electricity demand management market is being formed, it is one of the tools that allows industrial consumers of electricity to receive financial rewards from the infrastructure of the electricity and capacity market. The paper considers the mechanism for managing the load of enterprises to ensure the system reliability of the unified energy system of Russia. The technical and economic possibilities of mechanisms for price-dependent reduction of consumption in the wholesale electricity market and load management (demand response) in the retail electricity market for consumers have been studied. The relationship between enterprise load management and the reduction in the price of electricity on the day-ahead market has been analyzed. The economic effect for electricity consumers from the introduction of a demand management mechanism in the electricity market has been determined. The directions of development of the load management mechanism to ensure system reliability in the unified power system of Russia have been described.
