Impiö Oyj is a Valkean state-owned multinational petroleum and renewable energy company headquartered in Maarinnat, Valkea. It is active in all areas of the oil and gas industry, including exploration and production, transportation, refining, distribution and marketing, power generation, and energy trading. It is also a major chemicals manufacturer and a renewable energy producer, with signficant investments in biofuels, wind, solar, and nuclear energy. It is currently one of Lorecia's largest oil producers.
Impiö was founded as a mining company in 1887, but has since shifted to petroleum when it first discovered oil in 1926. It was nationalized in 1934 and became a key driver in the development of Valkea's petroleum industry. However, mismanagement from the Kansallist regime as well as increasing competition from Nynorsk Ostlijord and Caledonia saw the company's share of the market decline significantly throughout the 1960s and 1970s. After it was privatized in 1981, Impiö experienced a period of revitalization in the 1980s, as offshore oil reserves contributed significantly to its growth. In 1999, the Valkean government renationalized the company.
The company has a primary listing on the Våren Livet Stock Exchange. As of 2019, the Government of Valkea is its largest shareholder, owning 55% of all shares, while the rest is held in public stocks.
