A single keystroke by a substitute trader sent Finland's day‑ahead power price as low as -€500 per megawatt hour for delivery on 24 November. Kinect Energy Sweden said the trader overstated a wind park's output by roughly 1,000×, producing offers to sell 5,787 MWh each hour — about half Finland's demand — and the parent company estimates direct costs of up to $55m (€50.8m). Finnish authorities and system operator Fingrid took emergency steps to rebalance the market and have opened a formal investigation.

How a single bid upended the market Kinect Energy Sweden, a unit of New York‑listed World Kinect Corporation, told regulators the disruption came from human error by a substitute trader who overstated a Finnish wind farm's commissioning output by around a thousand‑fold. The incorrect entry turned an intended purchase into a sale: systems showed offers to supply 5,787 MWh each hour for 24 November. Immediate market fallout - The volume flooded the day‑ahead auction and pushed clearing prices sharply negative. - Dealers reported rates falling to -€500 per MWh in some hours. - Negative prices mean sellers effectively paid buyers to take electricity; some consumers were paid to use power during heavily discounted hours. Social posts encouraged running energy‑intensive appliances — a cultural quip in Finland where electrically heated saunas are common. - National consumption that day hit an annual record. Fingrid said it took additional measures to rebalance the grid after the auction results altered the supply‑demand picture. Costs and accountability Kinect told investigators the error could cost the group up to $55m (about €50.8m) — the company's estimate of direct financial exposure tied to the mistaken offers. Antti Paananen, deputy director general at the Finnish Energy Authority, confirmed the authority is investigating and said some details will be withheld from public release while inquiries continue. He added it was too early to determine specific liabilities. Possible sanctions include administrative penalties of up to 10% of a firm's previous year's turnover, or fines up to €100,000 for an individual trader. Regulatory and market questions The Energy Authority's probe will examine how a single entry could have such a systemic effect and whether trading‑system controls and exchange safeguards were adequate. Kinect has acknowledged human error by a substitute trader but declined to identify that person in the statement seen by regulators. The authority's decision to withhold parts of Kinect's response suggests investigators are treating some information as sensitive, possibly for confidentiality or legal reasons. Why risk controls matter Market rules and internal limits are designed to prevent a single erroneous entry from swinging an entire auction. The size of the mistaken offer relative to actual system demand was large enough to shift the clearing price sharply. What changes are made to trading controls, oversight and exchange safeguards will depend on investigators' findings; the incident exposed how brittle a day‑ahead market can be when a handful of large orders move in the same direction.
