Paragraph starter
This research by Sandwell et al. (2025) highlights the critical need to consider economic resilience in the design of decentralized energy systems. Their findings indicate that while solar mini-grids offer significant improvements in reliability and emissions reduction when integrated with national grids, a moderate decrease in electricity demand can severely undermine their economic viability. This underscores the importance of incorporating dynamic market analysis and robust risk mitigation strategies into the design process, moving beyond purely technical performance to ensure long-term sustainability and avoid potential 'stranded assets'.
