Summary: Central-Eastern European countries often do not fully utilize the potential for expanding thermal networks due to low energy market prices, which reduce the economic feasibility of proposed projects. While there are many optimization methods available for district heating systems, they rarely compare costs with individual heating solutions. Consequently, a novel method using multi-objective optimization is proposed to evaluate district heating systems in relation to individual systems, considering cost and carbon allocations in cogeneration units.

Summary: Biomass heating networks are a viable option for rural municipalities without natural gas supply, but their large-scale implementation faces challenges in profitability evaluation. The commonly used index, linear heat density, provides accurate estimations for high-density building networks, but not for low-density networks, leading to significant deviations when applied to biomass district heating networks. This study proposes a new index based on the cost-benefit analysis of investment, operation, and biomass costs to evaluate the profitability of biomass heating networks in rural areas. The application of this index in 499 rural municipalities in Spain shows high accuracy in estimating investment profitability, with R2 values between 0.8179 and 0.9442 compared to 0.2408 using linear heat density. The findings emphasize the importance of this approach for assessing biomass district heating potential in dispersed populations.
