Modelling Offtake Contracts and Subsidies in Co-located Energy Projects
Co-located battery and renewable energy projects are becoming more complex, with revenues increasingly shaped by existing offtake contracts and subsidies.
In this video, we explain how different commercial arrangements affect co-located wind, solar, and battery projects, including PPAs, Contracts for Difference in Great Britain, and EEG subsidies in Germany. We look at how strike prices, volume limits, and negative price clauses influence revenues, and why accurately modelling energy flows alongside contracts is essential for sound investment decisions.
We also demonstrate how Gridcog can model these scenarios in practice. Using a solar retrofit example, you’ll see how existing offtake agreements can be respected while testing different battery sizes and evaluating financial outcomes. The video also explores greenfield projects, showing how alternative offtake and merchant structures can be compared to optimise both financial performance and physical asset behaviour.
💡 Gridcog’s platform enables transparent modelling of co-located battery and renewable projects, helping developers and investors understand risk, optimise value, and make informed decisions.
