Power plant comprising: a lower level reservoir, a feed-through (line, hose, pipe, channel) for fluid communication from the lower level reservoir to a higher level reservoir, characterised by a pump arranged in connection with the feed-through in order to pump water from the lower level reservoir to the higher level reservoir in order to store energy by emptying the lower level reservoir, and a turbine/generator for power production arranged in or at the lower level reservoir in connection with said feed-through, or additional feed-through, for fluid communication between the lower level reservoir and the higher level reservoir for power production during flow of water from the higher level reservoir to the lower level reservoir. A method for power production. Use of the power plant.
