Catalyst models revenue stacking across markets such as FCR, aFRR, day-ahead trading and capacity markets, along with co-location with wind and solar, grid fees, asset sizing and scenario analysis, and turns the results into investment analysis and financial models for developers, investors and lenders. Users can import their own price curves and auction data, export reports to PDF and Excel, and connect outputs to their own financial models through an API. The Catalyst unit is led by Leon Schwarzott.
