Askim also borders to the former Trøgstad municipality to the northeast and the former Eidsberg municipality to the southeast. Askim produces large amounts of hydroelectricity at three dams / hydroelectric power plants in the river Glomma. From upstream to downstream: Solbergfoss, Kykkelsrud, then Vamma. There was nickel mining at Kykkelsrud at the turn of the 20th century. These mines are also one of the few places where "Spheroidal Norite" ("Potato Stone") is found. Askim has been an industrial city for most of the 20th century. The main employer, Viking Gummi (producing rubber products like boots and tyres etc.), shut down their rubber product production in 1991 after being taken over by the Continental Tyres owned Swedish Gislaved Tyres. Glava was the main employer by the 2010s, making glass cotton insulation etc.

Vamma Power Station (Vamma kraftstasjon) is a hydroelectric power station located on the river Glomma approximately 4.5 km south of Askim, Østfold, Norway. Sam Eyde formed Vamma Fossekompagnie in 1902 to build a power plant for a fertilizer factory. The factory plans were canceled in 1912 and Vamma Fossekompagnie was sold to Hafslund (company). Construction of the power station started in 1907 and in 1915 the first two turbines were completed. Another six turbines were built between 1915 and 1927. In 1944 the final two were complete. The installed capacity at that point was 113 MW from ten horizontal Francis turbines with dual runners. Between 1967 and 1971 a Kaplan turbine was built, adding another 110 MW, and it now operates at an installed capacity of 215 MW, with an average annual production of 1,275 GWh. In 2015 the construction of a twelfth turbine began on the south side of the dam. This is also a Kaplan turbine rated at 128 MW. The new turbine will allow the ten old turbines to only be used during the spring flood season, giving the plant more flexibility. The turbine is expected to add another 230GWh to the annual production. Testing of the turbine began on 16 May 2019., and was officially opened on September 8, 2019, by prime minister Erna Solberg. With the new turbine in operation it will be the largest run-of-the-river hydroelectric plant in Norway.
