Elkunder skal i EcoGrid let kunne skifte aggregator, så der opstår et fungerende elmarked, hvor aggregatorerne skal kæmpe om kunderne, ligesom vi kender det fra fx telefonabonnementer.
Valget af el-abonnement og fleksibilitet i indeklimaet er frivilligt, så EcoGrid arbejder med evidensbaseret adfærdsdesign, der gør det nemt at være fleksibel omkring opvarmningen af huset.
Aggregatoren aggregerer det fleksible elforbrug fra varmepumper og elvarme i husstandene. Fleksibiliteten bliver solgt videre af en BRP (Balance Responsive Partner) til elselskabet. Elselskabet kan så sætte varmepumpen i gang, når der bliver produceret mest el fra fx vindmøller.
EcoGrid kontrollerer varmepumper og elvarme i 1.000 bornholmske husstande. Elkunderne bestemmer en komforttemperatur, fx 19 – 23 grader, som elproducenterne kan bruge til at time opvarmningen med elproduktionen.
Første fase begyndte i 2012, hvor det smarte el-system blev installeret hos brugerne og reguleringer af elforbruget blev afprøvet. Anden fase blev indledt i 2016 med et opdateret konsortie og vil løbe frem til 2019.
EcoGrid benytter 15-minutters måleværdier fra elmålerne i hustanden, der svarer til minimumsintervallet i DataHub. For at evaluere demonstrationen kan vi bruge data med højere tidsresolution.
EcoGrids markedsmodel bliver afprøvet parallelt med det eksisterende elmarked men bliver tilpasset den nye engrosmodel og øvrig lovgivning i det danske elmarked.
"(EcoGrid's) concept can be applied generally. It reduces the need for production side flexibility, which is more expensive, and can compensate for traditional balancing power and services from replaced conventional generation. And for customers, it makes renewable energy more reliable, while helping them keep control of their bills.", EUSEW introduction to EcoGrid, 2016
EcoGrid vinder den ene af to priser foran 40 smart grid-projekter fra hele verden. Smartview fra New Orleans vinder hovedprisen.
"Integrating large amounts of renewable energy from wind and solar farms poses significant challenges to the electricity grid as we know it. Raising eyebrows all over Europe for its ability to handle large amounts of fluctuating renewable energy in its system, the EcoGrid project of Bornholm is a demonstration of the future of energy grids. The size of the project, and the amount of fluctuating renewables integrated, make the project particularly noteworthy.", Sustainia 100, 2012
"Det unikke ved (EcoGrid), er, at vi får mulighed for at teste det fremtidige elsystem hos mange forbrugere på en ø som Bornholm. Vi får mulighed for at undersøge, hvordan forbrugerne kan rykke på deres elforbrug for at få plads til den strøm, der kommer fra vedvarende energi.", specialkonsulent i EUDP Nadeem Fiwaz
"Vi ville gerne være med i et projekt, der skal hjælpe med at finde ud af, hvordan vores forbrugsmønster er i vores hjem. Det er så vigtigt, at vi bruger strøm med omtanke og at vi så vidt muligt bruger vores strøm fra vedvarende energikilder," EcoGrid-deltager Bent fra Bornholm

In EcoGrid 2.0, we are demonstrating an electricity market with flexible power consumption in private households. We are remotely controlling 1,000 heat pumps and electric radiators on the Danish island of Bornholm in an attempt to optimise their power consumption in line with the amount of power available in the power system at any given time. We don’t want the residents to freeze, which is why we are looking into what is required for homeowners to allow their power consumption to be regulated for them, and what their comfort limits are. We are also developing the link between private households and the electricity market with a new actor in the market: The aggregator.
Power consumption for cooking, entertainment, etc. cannot be adjusted without disturbing customers However, power consumption for things such as heating buildings or charging electric cars can, provided that certain agreed-upon comfort limits are respected. For example, consumers can stipulate that they must have a home temperature of 20-22 °C, that their summer cottage must be kept above frost temperatures or that their electric car must be fully charged by 7:00 am every day.
Every year, Denmark’s reliance on non-renewable energy sources such as coal, oil and gas decreases as more of the country’s power comes from sustainable sources such as wind, biofuel and solar energy. Today, wind turbines and solar panels account for approximately 50% of Denmark’s total electric power generation, but this varies from day to day in line with how much the wind is blowing or how cloudy it is. Because the amount of power generated from wind and solar fluctuates throughout the day, we will also increasingly need to adjust our power consumption in line with these fluctuations. Flexible electricity consumption can contribute to that.
There is a need for something that can link the households with the power system, as adjusting the power consumption of a single heat pump would not be very practical with regards to the power system. However, when you collect (aggregate) something like 500, or perhaps even several thousand of such devices, that’s where it begins to get interesting. An aggregator works as a bridge between the households and the power system. This new actor essentially pools flexible power consumption from hundreds of different households and sells it on the electricity market.
Allowing someone else to control how much power you consume in your own home is a fairly new concept. With EcoGrid 2.0, we are examining what is required in order for electricity consumers to be comfortable with allowing their consumption to be regulated for them, and what their comfort limits are. We are looking into whether it is financial incentives, better service or a more environmentally friendly lifestyle that appeals to the homeowners.
Exporting energy technology is good business for Denmark. Developing smart solutions for electricity markets, flexible consumption and IT solutions for aggregators, among other things, can create new jobs and lead to greater exports. Today,many countries are working to minimise their CO2 emissions in order to limit their impact on the global climate. Increased energy efficiency and a transition to renewable energy are two of the possible routes they can take. Exploiting the potential of flexible power consumption can help make the transition to clean energy less expensive for consumers.
EcoGrid 2.0 is a development and demonstration project

Elkunder kan i EcoGrid vælge mellem flere el-abonnementer – også kaldet aggregatorer - der blandt andet bruger fleksibiliteten i husets indeklima til at skrue op og ned for det samlede energiforbrug på Bornholm.Mere
EcoGrid benytter boligejernes fleksibilitet omkring husets indetemperatur til at moderere udsvingene i elforbruget. Elselskaber kan derefter købe fleksibilitet fra aggregatoren, når der ikke produceres nok energi.Mere
Danmark og verden skal øge brugen af vedvarende energi for at modarbejde klimaforandringer og opnå uafhængighed fra fossile brændstoffer. Vedvarende energi kræver smartere elforbrug, og det er det, som EcoGrid afprøver direkte på de bornholmske elkunder.Mere
EcoGrid bliver fulgt af eksperter og virksomheder fra hele verden og har siden starten i 2012 modtaget en række internationale priser.Mere
EcoGrid bliver udført hos 1.000 husstande fordelt over hele Bornholm. Du kan besøge EcoGrid og se installationerne i Villa Smart, som ligger i Rønne på Bornholm.
