District heating networks can technically enable energy-related co-operations between energy-intensive industries and municipal energy companies. The most common form of co-operation is to utilise industrial waste heat as the primary energy source in district heating networks. However, another type of co-operation is to jointly own a plant that produces both process steam for the industry and hot water for district heating. In this article, eight Swedish energy co-operations are studied and the main focus is on the process leading to co-operations of this kind. Different aspects of factors that facilitate or obstruct the start up and continuous daily operation of a co-operation are discussed. The main conclusion is that while the primary reasons for the foundation of such co-operations are favourable techno-economic factors, this is not enough for a co-operation to emerge. This study highlights the importance of people with a real ambition to co-operate in both parties in the co-operations. 相似文献

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

We describe energy use in Swedish homes from 1963 to 1980 using data assembled and analyzed for the first time. Changes in energy use by fuel and purpose before and after the 1973 oil price shock are illustrated and discussed, and savings in space heating in the year 1980, compared with the pre-embargo period, are quantified. We discuss two important elements of Swedish energy conservation policy, the building codes and the system of grants and loans to homeowners. We conclude that the grants and loans probably accelerated home retrofit measures, while the building codes will play an important role in reducing residential heat losses over the long term. 相似文献
