NVE is responsible for monitoring and mapping unstable rock sections in Norway.Today there are 10 unstable rock sections with high risk that are continually monitored by NVE.  The most common measuring methods are GPS and total station, ground based radar system as well as laser and tension leg. Different camera systems as well as communication via radio are also used. The installations are often inaccessible, with custom power supplies as needed. Many of these electricity supplies are hybrid systems with batteries, solar panels, windmills and methanol fuel cells. These are designed based on electricity requirements, accessibility, solar radiation etc. currently NVE has approx. 35 units in operation, but the number varies according to need. NVE would now like to enter into a framework agreement for the delivery of methanol fuel cell units with accessories (methanol and fuel manager).
