In cooperation with Alliander, an exploratory impact analysis was conducted in 2022 on the social value of various facilities for delivering power when the grid is temporarily unavailable. Traditionally, the emergency power generators are diesel powered. These diesel generators have multiple negative social and environmental effect. The analysis calculated the impact of a real, representative case based on data from the suppliers. The results showed that switching to a more sustainable fuel or hybrid generators is a relatively small investment in relation to the lower contribution to climate change and nuisance in the environment.
