About Westenergy


Westenergy Oy Ab owns and operates a modern Waste-to-Energy plant located in Mustasaari, near the city of Vaasa. The company was founded by five municipal waste management companies for the purpose of extracting energy from waste.

Westenergy Oy Ab is a non-profit company and does not pay dividends to its shareholders.

Cooperation at its best

This is a unique project as the owners of the company operate in approximately 50 municipalities located in five different regions in the western part of Finland. The five owners supply waste management services to over 400 000 people living in the area. Because of Westenergy, similar services will be provided at the same cost throughout the operation area for combustible waste. This non-profit company can offer its owners and thereby also the inhabitants of the area the best possible price for combustible waste treatment services.

The cooperation contract with Vaasan Sähkö Oy guarantees a market price for the energy produced in the plant. The energy price correlates directly to the gate fee and thereby also with the waste management costs paid by the public. This kind of cooperation between municipal waste management companies and an energy company is unique in Finland.
