This study re-examines the methodology for calculating connection fees to centralized heating systems in Russia, emphasizing its ecological and economic implications. The research highlights the inefficiencies of the current methodology, which calculates fees based on connected load rather than the physical length of heating networks. By proposing a new length-based fee calculation, the study underscores the potential for reducing unnecessary resource consumption, minimizing environmental impacts, and improving cost transparency. The ecological benefits include optimizing network construction, lowering emissions from redundant infrastructure, and enhancing energy efficiency. The proposed approach, validated through case studies from PAO “MOEK,” demonstrates reduced deviations between connection costs and revenues, fostering a balance of economic and environmental interests. This methodology provides a blueprint for sustainable heating infrastructure development, supporting both ecological and economic goals. © 2025, Hysen MANKOLLI. All rights reserved.
