Femstenaberg

Our first Energy Park!

At Rabbalshede Kraft, we believe in a system where we make use of several renewable energy sources to create a reliable solution that can deliver green energy all year round. Therefore, we have the ambition to develop the Femstenaberg park into an Energy Park where wind power is complemented by solar energy and battery storage.

In the municipalities of Strömstad, Rabbalshede Kraft is developing the wind farm Femstenaberg. The project were initiated in 2008, in significant part due to a great deal of interest from landowners in the area. Much has happened since then, thanks to the rapid development of technology in our industry. The ability to build larger wind turbines means that we now can produce the same amount of energy with fewer turbines than the 16 originally planned for. Therefore, the wind farm now consist of a total of 7 wind turbines with a total height of 200 metres and an installed capacity of 6.6 MW per turbine.

As the farm is located in southern Sweden, it will contribute with an important addition of renewable electricity in electricity price area 3, which currently has a deficit in electricity production.

Rabbalshede Kraft is the developer of the park. Our construction contractor is Kanonaden Entreprenad AB, and the wind turbines are delivered by Siemens Gamesa.

From wind farm to energy park

We want to help drive the development of efficient and sustainable solutions forward. Therefore, we are reviewing how we can develop our parks from pure wind parks to energy parks where, in addition to wind power, add other technologies.

In Femstenaberg, we are planning for a 30 MW solar plant and battery storage with a capacity of 20 MW/MWh. The battery will be used to deliver support services to Svenska Kraftnät, which helps to support and ensure the balance of the power system. When fully developed, the energy park, together with the Lursäng wind farm located in neighbouring Tanum municipality, is expected to produce up to 200 GWh/year. This corresponds to the electricity consumption of about 40,000 Swedish households/year. In the long term, we hope to add production of hydrogen to enable even greater energy benefits from the park.

One benefit of energy parks is that we get a more consistent delivery to the electricity grid when different types of energy sources are combined. In addition, it is more efficient from a cost and land use perspective to allow different resources to share the same infrastructure, such as access to the electricity grid.

What is happening now?

The wind farms will be operational shortly, with Rabbalshede Kraft remaining as the long-term owner and developer. While the wind turbines are spinning and producing renewable electricity, we are working on plans to add solar power and battery storage - all to be able to deliver renewable electricity every day, all year round.

Right now, we are waiting for approval from the Swedish Electricity Market Authority to use our existing grid connection for solar power and battery storage.

If all goes well, we hope to inaugurate our very first Energy Park as early as 2025. Brilliant, isn't it?
