In the case of a set of buildings located close to each other, it is advantageous to consider the construction of an energy-integrated heating, electricity and sometimes cooling microgrid within which numerous renewable energy sources operate. Such heating networks are low-temperature in nature and are supplied with heat by a variety of renewable energy sources such as heat pumps (also working in a cascade system) integrated with photovoltaics or wind turbines. Networks of this type are also integrated with electricity and heat storage. NG Heat designs solutions for energy-integrated microgrids as well as manages them and optimizes the energy consumption by buildings connected to them using a cloud-based IT platform. An example of a microgrid scheme is presented below:
