Oomi Energia

Oomi Energia — One of Finland's largest electricity providers — successor to Helen Sähkönmyynti, Lahti Energia and Oulun Energia

About the company

Oomi Energia is one of Finland’s largest retailers, formed in 2021 when the retail operations of Helsingin Energia, Lahti Energia and Oulun Energia merged. This brings stable customer service, modern digital tools and a broad product range.

Oomi focuses on offering a broad product range — from spot-priced electricity to fixed-term, Jousto consumption-effect contracts, seasonal pricing and day/night variants. The company aims to serve every consumer type: low-usage households, heavy users, electric heating customers and the environmentally minded.

What sets Oomi Energia apart?

Oomi’s Jousto contracts reward stable consumption through consumption-effect pricing, and Sesonki is the only seasonal-priced contract in Finland (fixed in winter, spot-based in summer). The 24-month Fixed contract is also available as a day/night version, which rewards electric heating customers with a cheaper nighttime rate.

Who is Oomi Energia for?

Oomi suits the consumer who wants a broad selection from a single provider — you can start on spot, switch to Jousto and later move to a fixed-term contract without changing providers. A large company also means stable customer service and comprehensive digital tools.

Customer service and online tools

Oomi offers comprehensive digital customer service plus a phone line. The provider has its own app where you can track consumption to 15-minute precision, check the spot price and optimise usage for cheap hours.
