Hydroelectric power is by far the dominating energy source in Norway, accounting for approximately 95% of the total produced. Snow accumulates the mountainous regions throughout the winter and represents an essential energy storage in the national and international energy system. Improved knowledge on snow water equivalent (SWE), which describes the amount of water in the snowpack, can help improve meltwater run-off forecasting models, which regularly deviate from actual run-off by up to 30%. This in turn can help reservoir managers make better production control decisions to avoid situations such as water spill-off caused by underproduction, where meltwater continues to flow into full reservoirs, and energy production lost. Better forecasting could also help companies produce hydroelectricity when the pricing is optimal, instead of emptying the reservoirs due to uncertain flood forecasts. Smarter production can therefore lead to less economic and energy waste, and consequently more predictable prices in the energy market. Currently, there are no technologies available that are capable of giving accurate SWE measurements covering large areas. The MESSENGER-SWE project will seek to develop and demonstrate a groundbreaking cost effective distributed system for automated measurements of Snow Water Equivalent in hydropower catchments. MESSENGER-SWE will be a low cost, permanently installed system providing data with a regularity and coverage factor that is unobtainable using current in-situ, automated and survey based measurement methods. MESSENGER-SWE will be ideally suited for ground-truthing of Satellite estimates for SWE, and will therefore enable the possibility for daily updates of SWE measurements over regional and national length scales, and thereby enable improved melt-water runoff forecasts that reservoir managers can use to make better decisions regarding hydropower production control. The initial phase of the project will focus on research aspects related to the core measurement technology.
