CMP432 aimed to address perceived defects in the cost-reflectivity of the “Locational Onshore Security Factor”, in order that Transmission Network Use of System (TNUoS) charges would better reflect the way Transmission Owners plan for a secure network, based on the Security and Quality of Supply Standard requirements.
