Pilot Heerlen: Local Energy Market: Exchange of heat & cold and renewable electricity generated in the built environment.

Low temperature and low-energy heat networks are currently gaining interest, as examples from GER, AUT and DEN show (IEA Annex 64 en DHCTS1). However, there are not many operational grids. In Heerlen is one of the most innovative grids of Europe. This 4th generation district heating and cooling network (DHC-grid) is operated by Mijnwater BV. By smart energy (heat/cold/electricity) exchange between connected buildings and (sub)surface infrastructures heat/cold buffers, substantial reductions in cost and CO2-footprint can be attained for urban areas. Residential and non-residential buildings connected to the DHC-grid can be both producer and consumer of heat and cold; depending on the actual situation in time. Optimization of the energy exchange involves peak shaving, cell balancing etc. Optimization of these grids is aimed to gain sustainable, technically attainable, cost effective and social accepted configurations for energy supply in urban regions. Such 4th generation DHC-grids involve a manifold of interactions between prosumers. In this pilot it is tested, based on outcomes of WPT1/2/3, how blockchain technology can support the handling of this complex (in time and space) energy exchange. The pilots also build further on results obtained in STORM-DHC project in Horizon2020. TIORC will bring in a pilot house in the built environment which is refurbished into zero-energy, to demonstrate the effect on human behavior when they can trade self generated renewable energy.
