With Market Data in Aiolos Forecast Studio, you can assess forecast quality and improvements in not only energy (MW) but also calculated in costs. The data is imported from e.g. Nord Pool.
Evaluation can be made on actually made forecasts, or as easily on simulated forecasts with backtesting in Follow Up.
The backtesting gives you a tool to calculate an offer estimate to bring in a new customer in the portfolio.
In Aiolos Forecast Studio Home tab the Market Data is integrated in the Home Live tool by showing regulation prices.
