We consulted on certain financial parameters of the cap and floor regime for electricity interconnectors included in Window 3 in September 2023. However, before reaching a decision, we are consulting further on the detailed parameters for the cap rate of the regime.

In this consultation we propose a specific methodology for estimating the equity beta parameter for Window 3 interconnectors, as well as updating the methodology for Total Market Return and Risk Free Rate.
