MCR 0144 – Data changes to accommodate new unmetered lamp types

This MCR has been raised to add to the code value list for the unmetered type code in the retail market design. This is as a result of four new public lighting lamp types.

Background:

ESBN has been advised of two new unmetered lamp types will be used for public lighting in the near future. New code values need to be added to the retail market design for these new types. Suppliers may need to take account of these in receiving the 700 and 701 messages. This DR impacts DUoS billing and may affect supplier billing.

The new lamp types will increase luminous efficacy meaning that you can replace the SON/CDM lamp types without loss of light levels but with useful energy savings. Also improved control gear increases overall system efficiency for further energy savings.
