CP1389 – Removal of Lux Meter Requirement for PECU Arrays
Formal title: Removal of Lux Meter Requirement for PECU Arrays
Current Status
Summary
BSCP520 ‘Unmetered Supplies Registered in SMRS’ defines the required minimum specifications for a Photo Electric Control Unit (PECU) Array. BSCP520 requires PECU Arrays to include a Lux Meter (otherwise known as a Light Meter). Although a Lux Meter is included in the minimum specification, the data derived from it is not required for Settlement purposes. Since the data from Lux Meter is not required for Settlement purposes, it is difficult to justify the cost and additional burden of providing a Lux Meter.
CP1389 proposes to remove the Lux Meter specification, allowing it to be an optional item during procurement and during the working life of a PECU Array.
