We use thresholds to help determine ‘competing’ load applications as part of our Applications and Queuing Policy (AQP). Thresholds are currently defined by demand values for a given load area or network region.
Following a review of the threshold levels in June 2014, we revised our ‘Non-Competing Application Thresholds’ test and will now only consider new load applications which meet the following two criteria to be non-competing for the purpose of the AQP.
- The total load must not exceed 1.5 MVA for its National Metering Identifier (NMI), and
- The load application must be eligible for network tariffs RT1-RT6.
Customers on network tariffs RT1 – RT6 best represent customers that are considered part of ‘natural load growth’.
The revised ‘Non-Competing Application Thresholds’ test will apply across the South West Interconnected Network (SWIN) from September 2014 and replaces all previous thresholds identified in our 2013 Annual Planning Report. This amendment will ensure there are consistent thresholds across the SWIN.
All load applications deemed to satisfy the two revised ‘Non-Competing Application Thresholds’ test criteria will be granted firm access to the SWIN. All other load applications will be subject to a Competing Applications Group if there are multiple applications behind a common network constraint, or as part of an Applicant-Specific Solution process.
