he purpose of regulation is to save water, and thus energy, from the spring flood period for use during the next winter season. This maximises the production of energy during the winter when the demand is highest and the profit is the best. To be able to accommodate the spring flood the lowering of the reservoirs during the winter has to be adapted to the expected volume of the spring flood. Reservoir operators intend to keep the 90% level of the reservoirs over the summer to guarantee maximum possible energy production.

Risks assessed
The timing of the reservoir lowering is very important. Reservoir managers want to avoid lowering the levels too early, which could result in production losses, or too late, which could result in losses due to spilling of water to ensure dam safety.
About
HSFS provides seasonal forecasts of the spring flood onset and volume (1-5 months ahead) in support of hydropower reservoir regulation planning.
