This is an updated version of the Interconnector Cap and Floor Regime Handbook originally published in 2021.

We are publishing this updated handbook for your general information. We implemented the changes in this handbook to reflect regime policy updates, include information on the Window 3 application window and reflect general updates to our assessment framework since 2021.

The purpose of this handbook is to:

  • explain what Ofgem’s cap and floor regime for electricity interconnectors is and where to find the main regime policy information;
  • provide up-to-date information on our implementation of, and changes to, the regime policy and design; and
  • provide key information on Certification, Access Rules and Charging Methodologies that apply to electricity interconnectors.

This handbook is a working document and is updated periodically.
