    PowerMatching City

    PowerMatching City is part of the Integral Project: a consortium of eleven European partners seeking to build and demonstrate an industrial-quality reference solution for the aggregation level control and coordination of distributed energy resources, or, in other words, a smart grid. The Integral Project gets its name from the project partners’ ambition of designing an integrated coordination system for three typical network situations: 

    •          Normal operation 
    •          Critical situations 
    •          Recovery from blackouts


    For each of these three situations, a demonstration project is being built. The results of the field tests will be used to realize a generic coordination mechanism.

    PowerMatching City is one of the three demonstrations, focusing on ‘normal operation’. The demonstration has been realized by DNV KEMA in cooperation with ECN, Essent and Humiq. The coordination mechanism developed by the means of this field test addresses the question of how a market can be structured, so as to promote the interests of all stakeholders: 

    •          Prosumer: maximizing economic benefit 
    •          Network operator: reducing peak loads 
    •          Producer/Supplier: minimising imbalance costs by using the cluster as a virtual power plant                                                                                   


    In Hoogkerk, a suburb of the Dutch city of Groningen, 25 homes have been equipped with a mix of decentralized energy resources (PV-solar, microCHP and hybrid heat pumps), smart appliances, smart meters and electric vehicles. Together they are called the PowerMatching City project. Wind energy is also supplied by the Kreileroord wind farm. Stabilization and optimization of the network are realized by trading energy on a local market, based on a realtime price signal using the PowerMatcher concept.

    • DNV KEMA launches new risk management guidance for the CCS industry

      News: DNV KEMA launches new risk management guidance for the CCS industry

      31 January 2013 | Europe, Sustainable Energy, Carbon Reduction

      In August 2011 DNV KEMA initiated the CO2 Risk Management (CO2RISKMAN) Joint Industry Project to develop a publicly-available guidance on major accident risk management of the carbon dioxide (CO2) stream within CSS projects. This guidance is now complete and provides the CCS industry with clear and comprehensive information to help in the development of effective CO2 risk management across the whole CCS chain from capture facilities through to underground injection.

    • DNV KEMA expands High-Power Laboratory to facilitate super grids

      News: DNV KEMA expands High-Power Laboratory to facilitate super grids

      29 November 2012 | Europe, Finance, Sustainable Energy, Smart Cities

      DNV KEMA will invest about €70m in the expansion of its high power laboratory in the Netherlands. The laboratory will be the first in the world in the extreme testing segment for the upcoming market for super grids.


      With smart grids, growing cities can leapfrog into the heart of the future while simultaneously making their energy infrastructure stable, reliable and efficient. Such grids offer flexibility to match the demand for and supply of variable sources, and allow resources such as natural gas to be optimised for every generated unit of electricity and water, thus saving energy, minimising harmful emissions and creating a healthy city that can successfully compete at an international level.
