What Rebase Energy does
Rebase Energy (legal entity Rebasian Technologies AB) is a Sweden-based energy technology company operating a Python-first energy forecasting platform that creates, deploys, and monitors forecasting models for distributed energy systems. The platform combines a multi-model ensemble of six global weather forecast providers (ECMWF, DWD, NCEP/GFS, MetNo, MeteoFrance, MetOffice) with proprietary machine learning models to predict power production and consumption, with claimed outcomes of 20% higher forecast accuracy versus single-model approaches and a 10% average reduction in imbalance costs. The product surface consists of the Rebase Platform (core forecasting service), a REST API with Python SDK and a Hugging Face / GitHub / Slack developer ecosystem, and the newly launched Rebase Dashboard (private beta, October 2025) for customizable real-time visualization by trading and forecasting teams. Specialized features include a wind-turbine icing forecast used by Nordic traders.
The company targets energy market professionals across six horizontal segments: energy traders, power producers, district heating operators, distribution system operators (DSOs), virtual power plants (VPPs), and energy optimization providers. Named customers include Tibber, E.ON, Jämtkraft, SFE, Modity, Qurrent, Aire Energy, Repowered, Bixia, and VITO, with operations primarily across Sweden, Norway, and the Netherlands. Revenue is generated through subscription or license-based platform access with custom-quoted pricing, annual invoicing in advance, 30-day payment terms, and a free trial pathway. The go-to-market blends self-serve API onboarding with a sales-led enterprise motion through a dedicated CCO, supported by content marketing, an open-source community, and the HEFTcom forecasting competition co-organized with the University of Glasgow and IEEE PES.
The company was founded in 2020 and operates with 1–10 employees (five named key team members including CEO Sebastian Haglund, CTO Mihai Chiru, CCO Karl Thunell, Senior Data Scientist Ilias Dimoulkas, and Senior Full-Stack Engineer Henrik Kälvegren). It joined the Third Derivative climate-tech accelerator in March 2024 and remains privately held with headquarters at Birger Jarlsgatan 57 c, Stockholm.
