Seasonal Normal Review - May Update

The Xoserve Demand Estimation Team would like to share with you an update on the Seasonal Normal Review, ahead of its implementation later this summer.

This update is the latest in a series that started in October last year, when we reported on the first key milestone of the review - the Industry approval of a revised formula for the Composite Weather Variable (CWV). We also provided some background information on what the Seasonal Normal Review is and why it is important.

In our second update in December, we concentrated on the Industry approval of a new basis for defining ‘normal’ weather, referred to as the Seasonal Normal Composite Weather Variable (SNCWV). This update also included an explanation of why weather correction is necessary, and how decisions relating to the SNCWV review were taken.

You can read the full update here and you can also find more information on the work of our Demand Estimation Team, including frequently asked questions on key topics, on the website.

This month, we would like to provide you with more information on the Seasonal Normal Review process.  This also includes an explanation of where there may be impacts to operations within your own organisation.

There will be a further update from the Demand Estimation Sub Committee (DESC) following its meetings in July.

If you have any questions or comments on any aspect of the Seasonal Normal Review, please contact your Customer Advocate, or the Demand Estimation Team who will be happy to help.
