Viking as a Stand-Alone Energy Solution

The Viking wind turbines are compatible with stand-alone systems (also called off-grid systems), where the turbines deliver the energy production directly to an independent unit and are thereby not connected to the electrical grid.

A stand-alone energy solution means that the wind turbines can be placed in areas, where there is no access to an established electrical grid or at places, where the coupling to an electricity supply meter and any added subscription is economically unsustainable.

Instead of connection to the electrical grid, the production from the wind turbines is stored directly in battery banks or the turbine runs parallel with a diesel generator. From here the electricity will be converted so the energy can be used for various electrical devices.

Furthermore, the Viking VS wind turbine can do without a battery bank and a diesel generator by adding an UPS (uninterrupted power supply) for the wind turbine. Hereby you can use the electricity directly from the wind turbine while it is being produced. The UPS is used for starting up the wind turbines after a period without any wind.

The wind turbines are hereby very valuable in sparsely populated areas and/or remote areas without electricity supply. This could e.g. be isolated settlements or refugees camps as this solution permits lighting, heating, communication with the outside world and a lot of other necessities, which are essential to a community in the 21st century.

Case 1: The Vejroe resort

On a small island in Denmark, green energy solutions of the future are being developed. The transition is ambitious but necessary, both when it comes to the overall sustainability of the island as well as for the future success of a green Denmark.

Besides the energy project which includes two wind turbines from Viking Wind, a resort has been erected with a hotel, conference rooms, greenhouses, and an orangery to produce organic foods. 16-20 people are employed full-time to take care of the guests of the resort.

The clear-cut target of 100% self-sustaining renewable energy on Vejroe is brought about as much from necessity as it is from curiosity. Today the island is not connected to the mainland, either with cables nor regular transportation. The former diesel-based energy supply required thousands of liters of diesel to be transported to Vejrø to power the diesel generators. This was an impractical and expensive way of supplying energy for the island. The annual energy bill was totaled more than 1 million Danish kroner, and for that reason alone, there was a strong incentive to make the island self-sustaining with sustainable energy and heat.

The project is also driven by the desire to explore, test and learn how an island in the best and most economical way can become self-sustaining with green energy. You can read more about the project here

Case 2:  Energy to an isolated area in Argentina

With great success, Viking Wind has delivered wind turbines for a stand-alone project in Chorriaca in Argentine. The purpose of the project is to supply vital and renewable energy to Patagonia, which is the southernmost and isolated region in Argentine.

Today the three Viking wind turbines deliver energy to a hybrid solution, which supplies electricity to the small village Chorriaca, all day, all year. This is necessary if this small village is to survive in the future. The electricity is elementary in people’s striving for cultivating the land, raising animals and keeping up the communication with the outside world continuously.

The project is part of The Argentina Patagonia Renewable Energy Projects, which is developed and driven by the organization Global Sustainable Electricity Partnership. You find further information about the project here. 

 

Viking is Compatible with Various Stand-Alone Energy Solutions:

  • Integrated UPS solutions
  • Diesel generator for back up
  • Battery bank for storage and back up
  • Hybrid system with several energy sources connected (e.g. sun and wind), a battery bank and an autonomous control system, which automatically compensated for the difference between energy production and consumption.
