Seasonal Normal Review - May Update

The latest update from Xoserve's Demand Estimation Team on the Seasonal Normal Review.

Published on 29 May 2020

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.
