IntegrCity

IntegrCity aims at developing and implementing a decision-support platform focusing on planning and designing integrated energy networks and further infrastructure developments. While city planners and energy companies can take advantage of the platform while planning energy supply infrastructure, the projects have also tested different energy supply and energy storage solutions both in Sweden and in Switzerland.

Nowadays, energy supply networks in cities – natural gas, electricity and heating/cooling – are almost always planned and operated separately from each other. When demand and productions are not simultaneous and the consumers’ energy usage behaviour changes, the cities are struggling with the energy supply. The key to solving these problems is the combination of a multi-energy conversion system and developed energy storage. This combination allows energy systems to adapt to increasingly decentralized energy production, interacting with existing energy networks. The “smart integrated solutions” for energy management and conversion increase interoperability capabilities between different energy vectors, and open opportunities to develop additional, innovative services to the one based on existing infrastructures and related supply structures. IntegrCity, a Swedish-Swiss project, aims to improve the planning and implementation of different energy systems with a decision-support tool.

The tool can be used both when retrofitting the existing cities and while planning new cities as it can simulate what happens when different energy resources are used in connection with each other. The decision-support tool can also steer the usage of different energy source so that the energy network can maximize the usage of renewable energy and then use the non-renewable sources as a back-up. IntegrCity is tested in two Swiss cities (Vevey and Geneva) and Stockholm (Hammarby Sjöstad). Cities, energy companies as well as other stakeholders are involved in the project as the combination of different energy sources can bring added value to all the partners.

Partners in Sweden:
Veolia, Riksbyggen, ElectriCity (Hammarby sjöstad), Europe Power Solution AB and City of Stockholm.
