GEWI GmbH

What GEWI GmbH does

GEWI GmbH is a Hannover-based energy services company founded in 2011 that specializes in direct marketing (Direktvermarktung) of electricity generated from renewable energy sources in Germany. The company markets approximately 5,900 MW of wind, solar PV, and biomass capacity on behalf of plant operators, ranking third among German wind energy marketers in the 2025/2026 Energate survey. GEWI is a participation company (Beteiligungsgesellschaft) of GETEC ENERGIE GmbH, with a minority stake held by wind developer Umwelt Management Aktiengesellschaft (UMaAG) since 2012. Its small, specialized team operates under three core product lines: the EEG Marktprämienmodell (market premium model) for subsidized plants, Power Purchase Agreement (PPA) marketing for post-subsidy and new installations, and SPOT-Vermarktung for unsubsidized spot-market sales including origin certificate (Herkunftsnachweise) trading.

The underlying technology stack centers on operational energy economics: production forecasting, balance-group management (Bilanzkreismanagement), scheduling (Fahrplanbewirtschaftung), and settlement/billing (Abrechnung). GEWI operates a web-based customer portal (Kundenportal) for plant operators and integrates with the energy & meteo systems (emsys) virtual power plant platform for remote plant control, live data, and grid operator measurements. A March 2025 multi-year contract for the 200 MW Trianel Windpark Borkum II marked GEWI's entry into offshore wind direct marketing, expanding beyond its historical onshore focus and adding a more complex redispatch process capability.

GEWI's business model is a recurring service-fee model deducted from market revenues, with pricing not publicly disclosed. PPA contracts run up to five years under a "Pay as Produced" structure; market premium and SPOT engagements operate on monthly billing. Distribution is primarily direct sales to plant operators, supplemented by a channel-partner arrangement with parent GETEC ENERGIE, whose industrial and commercial buyer network provides structured offtake access for PPAs. The company is licensed under EEG with REMIT reporting obligations to the Bundesnetzagentur and EEX Transparency Platform. Growth has been strong in volume terms — portfolio expanded from 4,300 MW to ~5,900 MW over roughly two years — and GEWI was named among the top three direct marketers by portfolio growth in the 2025 E&M industry survey.

Revenue model

1. PPA / Stromlieferverträge management services: GEWI acts as the structuring and marketing service provider for Power Purchase Agreements (PPAs) between plant operators and industrial/commercial electricity buyers. GEWI handles the energy economics: forecasting, calculation of balancing energy risks, and schedule management. Revenue is earned as a service fee deducted from the agreed PPA price. Contract terms of up to five years with renewal options are offered ('Pay as Produced' model).
2. Marktprämienmodell (Market Premium Model) services: GEWI buys EEG electricity and takes it into its balance group. It handles all energy economics processes (registration with distribution network operator, forecasting, balance group management, and billing). GEWI pays the plant operator the market value plus the management premium minus its service fee. This is a recurring revenue model based on managed electricity volumes.
3. SPOT-Vermarktung (Spot market marketing): For plants without access to market premium or other subsidies, GEWI markets electricity at spot market prices. Origin certificates (Herkunftsnachweise, HKN) can be generated and marketed. Revenue is derived from the difference between spot market proceeds and the service fee charged by GEWI. Plant operators bear the price fluctuation risk and opportunity.

• Vermarktung über Stromlieferverträge (PPA) Power Purchase Agreement (PPA) marketing service enabling operators of wind, solar PV, and biomass plants to sell electricity directly to traders and industrial/commercial end customers via bilateral OTC contracts. Includes support for EEG-20-Plus (post-subsidy) plants and new installations, with contract terms up to five years under a 'Pay as Produced' pricing structure.
• Direktvermarktung über das Marktprämienmodell Direct marketing service through the EEG market premium model for wind, solar PV, and biomass plant operators, enabling higher electricity prices than basic EEG feed-in tariffs.

GEWI pays the plant operator the market value plus the management premium minus its service fee.
• SPOT-Vermarktung Spot market marketing service for electricity from renewable sources without subsidies, allowing generators to market electricity as 'green' by obtaining and selling origin certificates (Herkunftsnachweise). Operators receive actual spot market prices and bear no quantity risk. Service fee is independent of plant and location, equal for all plants.
