The headwaters of the Glåma are exploited for
hydropower. Kuråsfossen kraftverk, built at the river's outlet from
Aursunden, entered service in 1896 and is regarded as Norway's oldest preserved
generating station. Its pioneering three-phase
transmission line carried electricity 24 km to the King's and Christianus Sextus mines, enabling early electrification of underground drilling and ore-hoisting. A major extension completed in 1952 now harnesses a 48 m drop and produces around 60
GWh annually. To support the plant and reduce downstream flooding,
Parliament approved regulation of Aursunden in 1921; the finished dam (1924) raised the lake by nearly 6 m and created a 215 million cubic metres storage
reservoir, making Glåmos a key node in the
Glomma water-management scheme. ==Notable people==
