Oulun Vesi (Oulu Water) has installed solar panel systems in its water production and waste water treatment plants, which are producing energy directly for the plants' own consumption.
The panels were procured in a single procurement exercise, and have been installed both in connection with a site renovation exercise and in the form of a specific procurement. The repayment period for the investments is estimated to be 7-10 years and, on the basis of the first years of use, this appears to be on track.
