Designing Co-Located PV/Wind + BESS in Germany
Webinar
This webinar quantifies the real-world economic impact of combining Battery Energy Storage Systems (BESS) with photovoltaic and wind power plants (co-location) in Germany.
Using Catalyst, we model how regulatory frameworks, increasing negative electricity prices, and different storage configurations affect revenue stacking and overall project profitability — moving from theoretical understanding to concrete numbers.

Contents
- Co-Location Regulation (EEG 2023 & Solarspitzengesetz): How the decision between "Green" (exclusivity option) and "Grey" (delimitation option) storage integration impacts the market premium and the ability to charge from the grid.
- Avoiding Price Cannibalization: Quantifying the saved energy through time-shifting during negative price periods and generation curtailments.
- Optimal Sizing & Technology: Determining the most profitable BESS overbuild (e.g., 30% to 100%) and the ideal storage duration (e.g., 2h vs. 3h) for wind and solar projects from an economic perspective.
- Live Modelling in Catalyst: A direct comparison of standalone projects with green and grey co-location scenarios across various electricity markets (Day-Ahead, Intraday, FCR, aFRR).
- Key Takeaways: Which co-location strategy (grey vs. green) achieves the highest Net Present Value (NPV) and how strongly these business cases depend on future market developments.
