What Enercast does

Enercast GmbH, founded in 2011 in Kassel, Germany, is a B2B SaaS provider of weather-based artificial intelligence for power generation forecasting of wind and solar plants. The company combines numerical weather prediction models from international meteorological services (including ECMWF and its AIFS system) with site-specific measurement data, processed through its proprietary self-learning ensemble engine (e³) and neural networks trained on each individual asset's historical behavior. Its product portfolio centers on the enercast Portal (the main SaaS interface), complemented by the Smart Energy API for decentralized applications, enercast YAS (yield assessment and backcasting), enercast WDA (raw weather data access), enercast SEF (business-optimized forecasts), and specialized modules for area-level forecasting and solar self-consumption. The platform delivers 400 million forecast data points per day, covering 240 GW of installed renewable capacity across 30 countries.

Enercast serves enterprise customers across the renewable energy value chain, including utility-scale wind and solar operators (Adani Green Energy, RWE, EDF, Enel, Vattenfall, ENGIE, Uniper, BayWa r.e., ReNew Power, Greenko), energy traders and direct marketers (Shell, Danske Commodities, ENGIE, Borusan EnbW), transmission grid operators (TenneT, 50Hertz), municipal utilities (EWE, Enercity, Sachsen Energie, SWM), and adjacent sectors such as automotive energy management (Volkswagen). The revenue model is primarily SaaS subscription for the Portal, supplemented by usage-based API access for decentralized energy applications. Go-to-market is sales-led for enterprises (live demos, trade shows such as E-world and Renewable Energy India Expo) with a self-serve free trial via the Portal. The company is privately held, has 11-50 employees, and has raised disclosed venture funding from Innogy Venture Capital and High-Tech Gründerfonds (2012 and 2014 rounds, with the latter undisclosed in amount). A non-core mining digitalization business was spun off into Castalytics GmbH in 2019 to focus capital on renewable energy.

Core offering

Enercast provides a SaaS platform that delivers AI-based power generation forecasts for wind and solar renewable energy plants, combining numerical weather prediction models with site-specific measurement data via its self-learning ensemble engine (e³). The platform is accessible through the enercast Portal and a Smart Energy API, supporting enterprise energy operators, traders, grid operators, and developers of decentralized energy applications such as EV charging and heat pumps.

Product overview

Enercast provides a unified SaaS platform (enercast Portal) for weather-based AI power forecasting of renewable energy assets. The core technology centers on the proprietary e³ ensemble engine that combines numerical weather prediction models with site-specific measurement data. The product portfolio includes the Smart Energy API for decentralized energy applications, the Smart Energy Forecast (SEF) for business-optimized predictions, the YAS (Yield Assessment System) for plant evaluation and backcasting, and the WDA (Weather Data Provision) for weather data access. The enercast Portal serves as the central interface combining multiple forecast outputs, interactive scheduling tools, and financial impact assessment capabilities. Specialized modules address solar assets with self-consumption and geographic area forecasts. The platform delivers 400 million forecast data points per day covering 240 GW of installed capacity across 30 countries.
