MOSL reports improved premises data and settlement accuracy

MOSL highlighted improvements in customer premises data and settlement accuracy as it published its 2022/23 Annual Market Performance Report which provides an overview of trading parties’ performance and assurance over the past 12 months.

The market operator pointed out in particular:

• non-household premises data completeness has improved significantly – with benefits for meter location and identifying whether a property should be in the market. MOSL added the improvements would also set the foundation for the planned central data cleanse; and

• Improving settlement accuracy has remained a priority – MOSL established a market indicator to provide clarity to trading parties around the accuracy of settlement across reconciliation runs. This has highlighted the impact on settlement of setting Yearly Volume Estimates to unrealistically low values.

Among other things, the report charted trading party performance across a range of metrics.

Retailer performance was largely flat on cyclic meter reads, data quality and vacant premises, but there was a 4.5% improvement on long unread meters.

Wholesalers showed improvement across most areas, with Unique Premises Reference Number and Valuation Office Authority data markedly better at around 25% improved performance each.
