Solar cell systems
To increase the use of renewable energy Ports of Stockholm has chosen to commit to solar cell systems. The company currently has six facilities and the ambition is to build more in the long term.
Ports of Stockholm's solar cell systems can produce electricity at a cost that is comparable to the purchase price of the electricity market. The facilities have a guaranteed effect of at least 25 years and experiences so far are positive.
