Strategic spatial planning – a missed opportunity to facilitate district heating systems based on excess heat.

Strategic spatial planning is important for developing long-term visions and strategies towards regional and local sustainability. This paper explores if and how strategic spatial planning could be useful for overcoming some barriers related to new sustainable ways of heating residential areas, using district heating systems based on industrial excess heat. This longitudinal study builds on interviews with municipal and private actors in six Swedish municipalities. It highlights that important barriers can be overcome by influencing the design and location of residential districts and industrial activities. Further, it identifies missed opportunities in local spatial planning practice as stakeholders are involved late in the planning when much is set, leaving little space for stakeholders to have an impact. Consequently, there might be a lack of knowledge and expertise in how such issues could enhance planning. Strategic spatial planning could facilitate conditions for excess heat-based systems of district heating as it implies a broader systems perspective which could enhance a broader planning scope. Plan programs could bring about more strategic spatial planning processes as these require early stakeholder involvement. If taking stakeholder involvement one step further to stakeholder collaboration or co-production, an even broader planning scope would be achieved. [ABSTRACT FROM AUTHOR]
