Issue 45: Introduction of Change of Supply Agreed Read Principle to correct all errors in Settlements

The Proposer identifies issues arising from MAP CP 0135, which was approved by the MRA Development Board (MDB) in June, with an implementation date of February 2013. This change will introduce new principles into MRA Agreed Principle (MAP) 08 relating to Change of Supplier Agreed Reads. Under these new principles, the old Supplier will now have an obligation to use reasonable steps to correct any error in Settlement.

The Proposer identifies that, where a dispute has arisen between Suppliers as to the correct number of dials that should be used for calculating energy used for Settlement purposes, there are currently no mechanics that exist within the BSC to allow Suppliers and their agents to correct Settlement data as required by these new principles.
