Our history

Arendals Fossekompani has a long and proud history


Company Founded

Arendals Fossekompani was founded on January 30, 1896. The original purpose was to utilize the water in Arendalsvassdraget to generate electricity. The company acquired several waterfalls, including Bøylefossen and Flatenfossen. Sam Eyde (image), Norwegian entrepreneur and industrialist, played an important role in the early development of the company.



Power and Industry

The construction of Bøylefoss Power Plant started in 1911, in parallel with the establishment of new industry in Eydehavn. The first electric power from Bøylefoss was delivered to Eydehavn in the summer of 1913. That same year, Arendals Fossekompani was listed on the Oslo Stock Exchange.

Growing demand for electricity for industrial purposes, led to the development of Flatenfoss Power Plant in 1927. The original plant was operational until it was replaced in 2009.



Financial Investor

Arendals Fossekompani gradually built a substantial financial capacity. At the end of the 1960s, the company changed its mission statement and built a portfolio of financial investments in listed and unlisted companies.

New Opportunities

Deregulation of the Norwegian electricity market presented new market opportunities. Arendals Fossekompani played an active role and established a subsidiary, Markedskraft, as an independent provider of services in the Nordic and European wholesale electricity market.
