The NEMoGrid project delivered a suite of technical innovations aimed at integrating renewable generation and prosumer participation into distribution grids. Central to the effort was the development of probabilistic load‑prediction algorithms that feed a decentralized energy‑management framework. This framework can steer prosumer behaviour and provide incentives that align local consumption with grid conditions. A key contribution was a resource‑efficient distributed controller for heat pumps that relies solely on local voltage and temperature measurements, eliminating the need for extensive communication infrastructure. The controller was shown to improve economic performance for participants while reducing the load on grid assets. In a Swedish rural network, the controller was first tested in simulation and then deployed in the Ramsjö test area. The results demonstrated a significant reduction in feeder load through targeted heat‑pump operation, with no noticeable loss of user comfort. Complementary fuzzy‑based regulation and market‑based control schemes were also evaluated, providing flexible options for balancing supply and demand. The project’s simulation environment, built by the ZSW, enabled technical and economic assessment of the business models, while empirical data from a user‑acceptance study at TU‑Chemitz informed the adaptation of these models to real‑world user needs.

The collaboration structure spanned several institutions and countries. The project ran for 37 months from 1 December 2015 to 31 December 2020 and was funded by the German Federal Ministry of Economic Affairs and Energy (BMWi). SUPSI in Switzerland led the scenario analysis, market and tariff design, and the distributed artificial‑intelligence component for the Swedish test site. The ZSW directed the modelling and simulation work package and contributed to other areas. SUST and TUC were responsible for scaling, reproducibility, and dissemination, as well as for improving user acceptance and cooperation. Demo sites were established in Rolle and Lugaggia (Switzerland) and Björklinge (Sweden). Due to infrastructure delays and the failure of the slock.it platform, the Swiss test site was moved from Rolle to Lugaggia, which already housed a 50 kWh battery, reducing the need for additional storage. Hive Power took over the development of smart contracts after slock.it ceased operation. Throughout the project, partners coordinated through defined work packages (AP0–AP6), adjusting responsibilities as necessary to maintain progress. The final report, published on 24 June 2021, documents the technical achievements and the collaborative framework that enabled the successful validation of new energy business models in real distribution networks.
