Power Matching City

In PowerMatching City in Groningen, the Netherlands, 40 households have been part of a laboratory for sustainable living, since 2007. The participating households have managed to find a balance between energy conservation and home comfort. They are also, to a certain extent, becoming self-supporting.

Creating a smarter and greener way of living

The smartness of the system is behind the scenes. Various technologies offer sufficient flexibility, and thereby enable consumers to retain their freedom of choice without sacrificing comfort or reliability. What the households have to give in return is space for a heat storage tank and/or a battery. Furthermore, they are given detailed insight into their energy consumption, enabling them to make decisions on the effective and efficient use of energy. In the PowerMatching City project, the inter-connected households are equipped with micro co-generation units, hybrid heat pumps, PV-solar panels, smart appliances, home energy storage and electric vehicles.

The Smart Grid Solution

A smart grid enables the needed flexibility and creates systems efficiency by storing heat in a buffer tank or electricity in the battery of an electric car. By charging the battery at a time when electricity is cheap, you can drive the car at the lowest possible cost. The energy trading on the local market is fully automated through a system – the Powermatcher – that optimises, independently and objectively, the interests of all participants.

DNV GL Securing quality and robustness

As member of the project team, DNV GL brought all stakeholders together. The team worked on the inter-operability of micro combined heat and power systems, hybrid heat pumps, and smart appliances in one system. Now in the second phase DNV GL will work on the end-user billing and monitor and evaluate the consequences for energy market processes.

DNV GL also developed an energy monitor, giving the participants online insight in their energy consumption and production. The billing touches the electricity and gas markets, as well as the heat and cold storage processes. In the PowerMatching City project we see how smart grids have the ability to inter-connect different types and scales of energy flows, as well as implement new services and technologies – something which again will create opportunities for new business models. This is unique in the world, and sets the standard for the future development of sustainable living.
