Heat Pump City of the Year 2011

On 14th April 2011, the European Heat Pump Association inaugurated its "heat pump city of the year" award. From a multitude of suggested cities and communities, the association’s executive committee picked the Island of Bornholm as the winner. The jury was convinced by the integrative approach that is taken in several projects aiming at the future energy system.

Steen Kramer Jensen from Energinet.dk, who accepted the award, was positively surprised - "We did not see this coming, we are very happy that our work is rewarded here" he said before explaining the approach to the audience at EHPA's event during this year's European Sustainable Energy Week.

Renewables and especially wind power have long been playing an important role in the Danish energy policy.  Lately, the Danish government made new statements pointing out the long-term vision of independence from fossil fuel by 2050.  On the shorter term, this will probably mean a doubling of the current wind power share from 20% today to 50% in 2025

The Bornholm pilot project is a unique test site (10.000 citizens) aiming to demonstrate 50% RES integration in a “real” system with integration of Heat Pumps into the Electricity Smart Grid. More than 500 residential water-to-water heat pumps are fully integrated in the market for both day-ahead and regulating power.

Energinet.dk has developed an Open Source Control Box for retrofitting existing Heat Pumps, thus enabling intelligent start and stop on behalf of prices on electricity and weather forecasts. The project is demonstrated in 3-400 Danish homes over the period 2010- 2012 as part of a feed-in campaign for establishing 5-10000 new heat pumps in Denmark

The expected outcomes of this project are:

- In deep knowledge about technical solutions, both hardware and software needed for local control and central Virtual Power Plant Server (VPP) so international communication and Smart Grid standards can be prepared,

- Outline of different business models on how to control flexible electricity consumption and estimate the savings,

- Large amount of measuring data from where it will be possible to develop new marked designs and system operation tools that is capable of handling distributed, flexible electricity consumption and heat pumps,

- Knowledge on consumer behavior and preferences,

- Identification of possible barriers and means on how to promote intelligent control of distributed, flexible electricity consumption and heat pumps.
