We require water companies to publish key information in a consistent format in order to support the bidding market for water resources, demand management and leakage services. Our water resources market information guidance sets out our expectations and requirements.
The market information is published alongside a water company’s draft water resources management plan (WRMP). Water companies are required to update the market information in line with their final WRMP within one month of publication. They will then periodically update during the next planning period.
Water company data is provided in a standard template in Excel format. In line with water resources planning, it is available on a water resource zone (WRZ) basis (the largest area of a water company’s supply system where all customers have the same supply risk). As in WRMPs, data is available over a 25 years at a minimum. Alongside the data spreadsheets, water companies will also publish a WRZ boundary file that can be imported to a Geographical Information System (GIS), such as an ESRI Shapefile.
