Too big to succeed? Institutional inertia in low-carbon district heating experiment

Abstract

The energy transitions are in an acceleration phase, where less carbon intensive technologies emerge, but their applicability is uncertain creating a need for real-life experimentation. Cities have become a focal context, where novel constellations of technologies and practices are introduced to reconfigure patterns of production and consumption. One area of urban energy governance gaining increasing attention especially in a Northern context is the low carbon transition in district heating systems that provide the majority of heating in the residential sector and has been primarily built around combustion technologies relying on fossil energy reserves. This article analyses a bidirectional low heat experiment in district heat in Finland by examining what are the dimensions of institutional inertia and how it impacts the reconfiguration of an urban energy system. Institutional inertia emerges from the technical innovation itself, land-use planning practices, the absence of formal regulations and via organisational inertia in the implementation of the experiment. We find that visions about the innovation can become constraints of the experiment, which limit learning and reshaping of innovation, thus preventing radical transformation of the district heating system and watering down the initial target of the experiment. We contribute to the conceptualisation of institutional inertia within the energy transition.
