Running a ride in Salling, it is clear that the use of windmills is not a new phenomenon in Skive Municipality. This does not exclude the possibility of a continued expansion of wind energy.
To achieve the ambitious goals, it is indeed an absolute necessity. The municipality's latest plans included three projects on wind energy:
- Testing of wind turbines on Skive's new town hall, 20 meters in height – so-called gable turbines. It is about the turbines with a diameter of less than 2 meters with a performance of max. 2.5 kW. A gable turbine is common in Germany but still has no Danish firms dared to throw money into an approval in Denmark. Testing can help to provide incentives to engage in a type and can help to provide guidance on what types of gable mills with the qualities that will be appropriate to target in Denmark.
- Establishment of two 3MW land-based wind turbines. The two turbines will produce approx. 15 million kWh/year, which corresponds to approx. 150% of the electric energy that the municipal buildings themselves are using. Profit from the two large turbines will be reinvested in new energy-saving technology and new forms of energy such as hydrogen and electric car technology. So we imagine that the surplus production can be used for test with hydrogen production and implementation of electric vehicles in the municipality.
- It establishes two 11Kw household turbines in two schools. The two lucky schools are Selden School in North Salling and Ørslevkloster School in the eastern part of Skive Municipality. Each of the two turbines – the type Gaia 11Kw – will annually produce around. 30,000 KWh and will return at approx. 8 years to oust the school's own consumption.
Financing
Generally, Skive Municipality finances all energy-saving projects with borrowing under municipal borrowing opportunity for energy-savings. When projects are approved, it is based on a statement of how much each building can be reduced in running water, heat and electricity accounts.
Of the 9 million DKK, which Skive Town Council has committed to energy-saving measures in 2009, it earmarked 124,000 for testing of small wind turbines. The test will be the basis of Skive
The municipality's strategy for minimizing power consumption in municipal buildings: The operating budget has been prepared for the two turbines with the following conditions:
- 2 pieces of 3 MW wind turbines incl. configuration, land acquisition, roads and land to the transformer – cost 57 million DKK
- Turbines expected to have a lifespan of 25 years
- The expected annual electricity production of 15 million kWh
- There is an anticipated price of the sale of power throughout the period of 49 cent/kWh
- The costs of ongoing operation and maintenance of the turbines is expected to constitute 10 percent produced kWh. (This corresponds to an annual expenditure of 1.5 million)
- Turbines are financed by borrowing at 57 million. Performance has a background in the calculation made by the municipality at the end February 2009 – first on a 25-year rate adjustment loans and a 25-year fixed rate bonds
The two Gaia turbines, each 11 kW, will be funded equally by the EBF pool in 2009 and will have a payback of approx. 10 years.
Status and results
Compared with gable turbine test, we do research in current suitable models. Department of Urban and Rural Development works on how to identify suitable areas for the location of the two large wind turbines.
