Water regulator Ofwat has developed a financial model to help it assess the water companies' AMP6 business plans as part of the PR14 price review.
The three main purposes of the financial model are:
- To determine the wholesale price controls
- To calculate the revenues arising from the retail price controls; and
- To help assess financeability of the appointee.
