Laanila biopower plant:  
Cleaner energy with cutting-edge technology

Oulun Energia's Laanila biopower plant, completed in 2020, produces electricity, district heat, and process steam energy-efficiently. The plant plays an important role in moving towards carbon-neutral energy production.

Around 70% of the energy sources used by the power plant are wood. The remainder is high-quality SRF (recycled fuel) from the circular economy.

The Laanila biopower plant of Oulun Energia represents the latest technology. Its boiler can utilise a wide range of fuel compositions, and their ratios can easily be changed. Process steam industry can be integrated around the biopower plant, opening up new opportunities for the bioeconomy in the region.

Laanila ecopower plant:
Non-recyclable waste utilised for energy

Oulun Energia's Laanila ecopower plant processes non-recyclable waste into steam and heat. At the same time, it reduces the load on landfills and the emission of greenhouse gases into the air. The steam produced by the ecopower plant, completed in 2012, is utilised in the industrial processes in the area.

Toppila power plant:
Domestic electricity and heating

The Toppila 2 power plant, completed in 1995, still produces a significant part of our electricity and district heat. The south wall of the power plant is covered by a solar power plant with 827 panels. In the 2030s, Toppila's heat production using wood and peat will be replaced entirely by renewable energy sources, such as recovery of surplus heat and electric boilers.

In the Toppila power plant, the thermal energy contained in the flue gases is captured by a condenser and converted into district heat. A more efficient use of fuel will help reduce emissions from the plant and improve energy efficiency.

Merikoski power plant:
Hydropower through the decades

The crown jewel of our energy production is the old Merikoski power plant, which has been producing hydroelectric power in the middle of Oulu since 1948. To this day, hydropower is still one of the key sources of energy. It produces renewable, zero-emission, and local energy and is an important source for regulating power.

The Merikoski hydroelectric power plant building was designed by architect Bertel Strömmer, and the building is part of the nationally significant built cultural environment of the River Oulujoki delta.

Finland’s longest fish pass, and the only one in the River Oulujoki, was built past the power plant in 2003. The Merikoski fish pass enables fish to migrate from the sea, past the power plant, to the upper reaches of the River Oulujoki.
