Wednesday 1 June
08.30 Breakfast in Green Solution House with all participants
Morning programme at Green Solution House, Rønne
09.30 Module 4 – The role of Østkraft
Ole Schou Mortensen, Director, Østkraft
Østkraft is producing, selling and distributing electrical power to the residents of Bornholm among others. Østkraft is involved in a lot of research & development activities within wind, solar, biomass and intelligent energy distribution systems, that can integrate huge amounts of renewable energy. During the last decade, Østkraft has built up an impressive array of renewable sources like wind, solar, and biomass, which can now supply about three-quarters of the island’s demand. In the process, Bornholm has transformed itself into a kind of living laboratory for testing new energy ideas.
10.00 Module 5 – Renewable Energy – District Heating
Per Martlev Hansen, Director, Bornholms Forsyning 
Bornholms Forsyning produces carbon-neutral district heating based on straw and woodchip-fired plants. A large woodchip-fired plant was opened in 2010 and supplies heat to 1,300 households. The plants are supplied with local fuels only: the straw is supplied by local farmers and the woodchips are chipped from surplus sawmill wood and surplus wood felled as part of ordinary forestry operations. In return, farmers receive the operation’s only residual product (ashes), which they use as fertiliser for the fields. In addition, two privately owned straw-fired plants on the island supply heat to 3,000 households.
10.30 Module 6 – Renewable Energy – Waste to Energy I
Jens Hjul-Nielsen, Director, BOFA
Bofa is Bornholm’s island-wide municipal waste-handling company and manages all waste produced on Bornholm. Bofa comprises an incineration plant in Rønne, a recycling centre, six waste-sorting sites and thirteen unmanned environmental stations placed around the island. Bofa has one of the highest reutilisation rates of any waste-treatment company in Denmark: 69% of all waste received at Bofa is recycled and 24% is incinerated, the latter of which generates virtually carbon-neutral heat for consumers in Rønne. The remaining 7% of the waste is deposited.
11.00 Module 7 – Renewable Energy – Waste to Energy II 
Jan Damkilde Christensen, Director, Biokraft
The Biokraft generates energy from biomass, primarily animal manure and organic waste. The biomass is mixed in three reactors and generates biogas, which is converted into electricity and district heating for Bornholm consumers. The degassed slurry is transported back to farms as fertiliser.
11.30 Coffee break and transport to destinations of Guided Tours
11.45 Tour – Waste to Energy I – A guided tour of Bofa’s sorting and waste-handling facilities in a new waste-management info centre in an abandoned water tower.
Visitors also see how Bofa tackles the challenge of handling waste generated by the island’s 600,000 tourists – more than ten times the island’s population – who visit Bornholm each year.
A thorough introduction to Bornholm’s waste-handling system and the efforts being made to improve this and to involve and increase the awareness of the island’s inhabitants and visitors of all ages.
12.45 Lunch
13.45 Tour – Waste to Energy II – The biogas plant generates energy from biomass, primarily animal manure and organic waste.
The biomass is mixed in three reactors and generates biogas, which is converted into electricity and district heating for Bornholm consumers. The degassed slurry is transported back to farms as fertiliser.
Afternoon programme at Green Solution House, Rønne
15.15 Module 8 – Solar projects on Bornholm
Peter Ahm, Director, PA Energy A/S
PV Island Bornholm
Photo Voltaic Island Bornholm is a research and development project that supports the EcoGrid project by promoting the setting up of the solar cell plant and collects data about how a high local concentration of solar cells can affect the voltage in the electricity grid. Behind the project are Østkraft, EnergiMidt, Energitjenesten Bornholm/Bornholms Miljø- og Energicenter, PA Energy, Teknologisk Institut, Danfoss Solar Inverters, Solar City Copenhagen and VedvarendeEnergi.
15.45 Module 9 – Heat pumps in the low-voltage mains 
Jørgen Christensen, CTO, Dansk Energi
The project is a collaboration between Østkraft, Dansk Energi, Aalborg Universitet and the Jutlandic energy company TREFOR.
In a few years from now, oil-fired burners will be phased out as part of the green change. Many of the oil-fired burners will be replaced with large water pumps. This will cause some special challenges. In the meantime, the heat pumps can bear the risk of overloading our current electricity grid and that is why we need to identify the challenges that will arise, when the increasing load on the electricity grid becomes a reality, as a result of the many heat pumps. The project is supported by Energinet.dk under the ForskEL arrangement. The plan is to perform measurements in selected parts of the electricity grid, on Bornholm as well as TREFOR. The measurements will illustrate how the increased consumption to the heat pumps will affect the electricity grid.
16.45 Reception & Guided Tour of the Green Solution House 
Introduction by Trine Richter, Director of Green Solution House
Hosted by the Municipality of Bornholm
Tour – The Green Solution House – a recirculation design with energy optimisation
The ambition was to realise visionary solutions in the fields of biodiversity, reusable materials, energy optimisation, water treatment and waste sorting. The 4,500 m² knowledge and conference centre Green Solution House adds a new dimension to the concept of sustainability, and at the same time, it is one of the first buildings in Europe to be based on a recirculation design that does away with all waste and eliminates its environmental impact. The building is dynamic – the Green Solution House will continue to develop as new innovations are developed.
19.00 Closing of Day II
