Risk-informed brownfield redevelopment: scaling renewable energy for a just transition

This chapter examines the feasibility of repurposing brownfield land for solar photovoltaic (PV) and wind energy as part of a just energy transition. A just transition emphasises the shift from fossil fuel-based energy systems to renewable alternatives while ensuring that social, economic and environmental benefits are equitably distributed.

The chapter combines literature review, policy analysis and Geographic Information Systems (GIS)-based spatial modelling to evaluate the role of brownfield redevelopment in advancing energy justice. Greater Manchester in the United Kingdom is used as an illustrative case study, where a multi-criteria GIS evaluation assesses the suitability of brownfield sites for renewable energy deployment. Key criteria include solar radiation, wind speed, site size, topography, grid proximity, flood risk and environmental constraints.

The findings indicate strong potential for solar PV deployment on brownfield sites, while wind energy opportunities are more limited due to spatial and environmental restrictions. To address redevelopment challenges, including ownership fragmentation, contamination risks and regulatory complexity, the chapter outlines risk management strategies integrating legal reform, financial incentives and inclusive governance.

Strategically redeveloping brownfield land for decentralised renewable energy can contribute to achieving net-zero ambitions by reducing carbon emissions, alleviating energy poverty and supporting sustainable urban regeneration.
