Forecast IMRP

This dataset includes forecast time weighted Intermittent Market Reference Prices (IMRP) and generation weighted IMRP.

This dataset is updated following the end of each Quarterly Obligation Period.

Please note that our forecasts simulate hourly prices across multiple scenarios, and the published prices represent the averages derived from these simulations over the quarter. Consequently, the capture price differences cannot be back-calculated from these averaged values as this detailed information is lost in the hourly averaging process over the simulations, but are taken into account in individual simulations.

Forecast Generation Weighted IMRP	Intermittent Market Reference Prices (IMPR) are used to calculate CfD Generator payments. Under the CfD, when the reference price for the electricity generated by a CfD Generator is below the strike price set out in their contract, payments are made by the LCCC to the CfD Generator to make up the difference between the reference and the strike price. The Intermittent Market Reference Price is calculated using day-ahead data received from EPEX Spot and NordPool. An IMRP is calculated for every hour of the day.
