Tjärdalsberget

We are exploring the possibility of establishing a wind farm in Tjärdalsberget, just outside Stöde, in the municipality of Sundsvall.

Why?

Electricity demand is increasing, not least in our part of Sweden. We have the opportunity to contribute to the production of renewable energy—and we want to do so. The Tjärdalsberget wind farm could help create the conditions needed for new, fossil-free industrial development in Sundsvall and Timrå.

Why here?

This location offers favorable wind conditions. We also own the land, where we currently conduct ongoing forestry operations.

Considerations?

A wind farm affects people, animals, and nature. Through consultations, we have gathered input from nearby residents, and we are conducting repeated environmental inventories in the area. Based on these findings, we have already adjusted the design and size of the project—and we will make further changes before submitting the formal application.

FAQ

  • The site selection is based on an analysis of the area’s potential, considering factors such as wind conditions, grid connection, national interests, and current land use.
  • The area is designated in the municipality’s draft plan for solar and wind power.
  • The current project area is already affected by ongoing commercial forestry.
  • The area is not covered by any national interest designation.

The location is being evaluated against constraints defined by municipal interests, reindeer husbandry, national defense, civil aviation, telecommunications, and others.

  • Reporting the environmental impacts of a wind power development provides a basis for the County Administrative Board’s assessment of suitability and is a requirement in the permitting process.
  • Several types of surveys and investigations are conducted to design the project with minimal impact on environmental values, people, and wildlife.
  • Natura 2000 sites are strictly regulated. No turbines or roads are constructed within these areas. Protective measures are taken if there is a risk of impacts, for example from runoff.

The County Administrative Board’s mandate is to carry out a thorough environmental review based on Swedish environmental legislation.

  • The Swedish Environmental Protection Agency’s guideline for noise from wind farms is 40 dB(A) outdoors at residential areas. This corresponds to the sound level of a modern refrigerator.
  • If noise exceeds 40 dB(A), the operator is required to take mitigation measures. There is no direct correlation indicating that taller turbines produce higher noise levels.
  • Noise calculations are based on the entire wind farm, and if there are nearby wind farms, the cumulative noise is also considered. In other words, it is the total noise level that must comply with the 40 dB(A) limit at residences.
  • To prevent ice formation on the blades, which can generate higher noise levels, the turbines can be equipped with de-icing systems.

The County Administrative Board is tasked with conducting a thorough environmental assessment in accordance with Swedish environmental legislation.

  • In accordance with the Swedish Transport Agency’s regulations, wind turbines are required to have obstacle lighting.
  • The regulations allow for dimming of the lights during dawn, dusk, and nighttime. To reduce the impact on the surroundings, the flashes are synchronized.

The Swedish Transport Agency sets the requirements for obstacle lighting.

  • Within a wind farm, there is a risk of ice throw under specific weather conditions. Warning signs will be placed at the access roads to alert visitors.
  • The turbines can be equipped with de-icing systems to reduce ice formation on the blades.
  • The wind farm will generally be accessible for visits and activities. During construction, access may be limited.

The wind farm owner is responsible for providing information about the risk of ice throw.
