Software to detect and eliminate 100% of avoidable energy losses on thermal grids for lower costs and reduced environmental impacts
DistrictLab is developing and commercializing a novel thermal grid design and optimization software application. The software, initially developed at the CEA, can be used on all district thermal grids, regardless of size, generation of technology, or renewable energy penetration rate.

District thermal grids are becoming more and more complex and the penetration of “non-manageable” sources is increasing. Unfortunately, the available management software has not kept up with these trends. DistrictLab is filling the gap with its design and optimization software. Many French thermal networks (e.g., Grenoble, Metz, Chambéry, Montpellier, Paris Airport, etc.) as well as Swiss networks (e.g., Lausanne, Geneva, Neuchâtel, etc.) and engineering firms in the field are already putting the software to use.
DistrictLab’s solution allows users to rapidly deploy a digital twin of the grid during design or operation. Known or possible operating conditions are reproduced in the simulation so that the software can calculate the best configurations for financial profitability and energy-efficiency.
Thermal grid operators can reduce thermal input power, forecast peak demand, curtail the use of additional generators, integrate more renewable energy, prepare for new customer hookups, simulate extreme temperatures, and more. In terms of financial savings, operators can lower costs by as much as 15% at the design stage, and between 2% and 6% during operation when the software is deployed on existing grids.
One of DistrictLab’s two founders is from CEA. The company is now commercializing its Districtlab-H solution and is developing new features through an R&D contract with CEA and a corporate partner. Initially, DistrictLab will target Europe and, in particular France, where 1,300 district thermal grids are expected to be commissioned or their capacity increased by 2035.
