The following work focuses on the study of the energy complex in a particular country (Sweden) and in specific conditions (Luleå municipality in the first and second decades of the 21st century). The conclusions and results obtained during the work might be interesting from the point of view of applicability of practice in other countries, as an example of successful experience in implementing an effective fuel and energy complex, which allows each of the parties (producers and consumers) to derive the maximum mutual benefit. The main features of the energy economy of Sweden as a whole have also been considered, which may contribute to the deepening of research in this vein, in order to allow other municipalities to be considered, which in turn will make it possible to assess the efficiency and prospects of the fuel and energy complex in the country as a whole. The work also proposes and considers possible points of intensification of the production cycle in order to increase production capacities and improve the conditions for consumers who, due to the geographical features of the country’s location, are forced to spend large amounts of money on innovative technologies, illustrated in consumer prices for electricity and heat supply (especially other municipalities in Sweden, for example, the difference between Luleå and them in terms of consumer prices can reach 30-40%).
