Much rain, a steep drop and nearness to Bergen meant that the power-making potential of the Samnanger water system was exploited early. Samnanger was thus one of the first power-producing municipalities in western Norway. With its subsequent expansion and new power stations, about 400 gigawatts of electricity per hour were produced on average each year. This is enough to meet the energy needs of 25,000 households.
Ådland, innermost in the Samnanger Fjord is an old church centre and transport centre; a nodal point in the transport from sea to land. The white painted church standing today, was built in 1851, but there were two older churches here in former centuries.
