Profitability of sparse district heating

摘要: The expansion of district heating into areas low heat densities (heat sparse areas) constitutes a challenge due to the higher distribution costs. profitability has been analysed from actual investments in 74 with 3227 one-family houses connected between 2000 and 2004 Goteborg, Sweden. was estimated probable price model, typical marginal generation cost, connections made. analysis identified factors as linear density sold per house explaining main variations profitability. concluded competition analysis. conclusion is that possible when reaching investment costs for local network generation. In Sweden, general competitiveness facilitated by high consumption taxes fuel oil, natural gas, electricity. Hence, it should be more difficult introduce other countries energy taxes.
