FPN

Title Carbon Intensity of FPN
Type number
Description Balancing Mechanism Units submit their Final Physical Notice to the ESO at gate closure. FPNs are a notice of BMU's intended profile over the settlement period. The carbon intensity of the FPN profile is a measure of CO2 emissions per kilowatt hour had all units followed their FPN profile.

BOA

Title Carbon Intensity of BOA
Type number
Description Once BMUs have submitted their FPNs, the ESO control room can instruct them to deviate from their intended profile by issuing bids and offers. If a bid or offer is accepted (BOA), the BMU will follow the BOA profile rather than the FPN profile. The carbon intensity of BOAs, the balancing actions taken in the Balancing Mechanism, is a measure of CO2 emissions per kilowatt hour of FPNs with the updated BOA profiles applied.

Difference

Title FPN BOA Difference
Type number
Description This metric records the difference between the FPN carbon intensity, where no balancing actions have been taken, and the BOA carbon intensity with balancing actions applied. It indicates whether the balancing actions in the BM have increased or decreased the carbon intensity of the system. It is positive if the BOA profile is higher than that of the FPN, and negative if vice versa.
