Strategy

The user chooses the strategy that the dispatch model follows.

Strategy nameDescription
Energy-onlyThe model optimizes revenue via energy arbitrage only. The model never makes ancillary service commitments.
Energy + ASThe model will co-optimize between energy arbitrage and ancillary service commitments.

Energy prices

Energy prices are a key input to the dispatch model. They come from the production cost model.

Ancillary service prices

Ancillary service prices are another key input to the dispatch model. They are generated by the Ancillary Services Pricing Model.

Using the historical correlation between energy and ancillary services prices, a regression model was built to project that into the future using the energy prices produced by the fundamentals model.
