Products and services

• Oomi Kiinteä Fixed-term electricity contract with a fixed price per kWh held constant over the entire 6, 12, or 24 month term, allowing Finnish households and businesses to predict their electricity bills; base fee €5.90/month.
• Oomi Jousto Hybrid electricity contract that combines a fixed per-kWh price with a consumption-impact mechanism tied to 15-minute Nord Pool spot prices, so customers can lower their bill by shifting usage to cheaper quarter-hours; 97% of Oomi Jousto customers pay less than Oomi Kiinteä fixed-price customers.
• Oomi Aktiivinen Open-ended spot electricity contract whose per-kWh price is recalculated every 15 minutes against the Nord Pool Finnish area spot price plus a 0.60 c/kWh margin; suitable for customers who actively monitor and shift consumption.
• Oomi Sesonki Seasonal 12-month electricity contract that charges a fixed winter price (Nov–Mar, 11.49 c/kWh) and a spot-based summer price (Apr–Oct, margin 0.50 c/kWh plus Nord Pool spot), aligning price risk with consumption patterns.
• Oomi Vakaa Open-ended electricity contract with a fixed per-kWh price (13.90 c/kWh) where Oomi must give one month's notice before any price change, providing price stability without committing to a fixed term.
