Swedish energy networks among industrial SMEs

摘要

Research and policy instruments for improved energy efficiency in industry have historically focused on large and energy-intensive companies, perhaps because a large part of the energy use is concentrated therein. However, small and medium-sized enterprises (SMEs) account for 30 % of Swedish industrial energy use. Research shows that both the relative energy efficiency potential and the cost-effectiveness for implementing energy efficiency improvement measures in industrial SMEs is higher, compared with large and energy-intensive companies. A significant difference between large companies and SMEs is their management capability, i.e. the difference between how energy is governed in-house companies. One way to approach SMEs is through energy efficiency networks, where 10-15 companies work together to improve energy efficiency. The networks are driven in turn by an external actor. The model has been successfully used in 70 networks in Switzerland and more than 50 in Germany, and is now emerging as a means to improve energy efficiency in Swedish industrial SMEs as well. While energy audit programs, nationally and internationally, is a thoroughly researched subject with developed methods, etc., this is not the case with networks, and in particular the Swedish networks. The aim of this paper is to study the current Swedish energy network activity in industrial SMEs. Results show that a large potential for improvement still exists in these networks, i.e. methods and tools used are still to be developed, as well as a more structured methodology on how the network are to be managed. Including experience from other country's networks could contribute further to more effective Swedish industrial SME energy networks.
