This Solution provides guidance on the integration of renewable energy (RE) sources into district energy. It can be of interest to both established and growing cities. For new district energy systems (DES), cities should explore opportunities to integrate local RE sources from the early planning stages. For pre-existing systems, the integration of renewables can be coordinated with system expansion and/or the retrofitting plans for the network as well as energy production. Decentralized production using multiple RE sources and technologies can offer several benefits as well.
It explores the different roles that local governments can play, including in creating an enabling framework in the context of urban and energy planning, facilitating stakeholder engagement, and as an owner/operator of a district energy utility. It also zooms in on technical aspects, such as different renewable energy sources, thermal storage, lower operating temperatures and integration with the electricity grid.
