The Independent Gas Transporters’ (IGTs) licences set out the arrangements for determining the maximum charge that licensees may levy on premises subject to the Relative Price Control (RPC) regime. As part of these arrangements, we publish both the Retail Prices Index (RPI) and the weighted single supply point charge (wSSP) average of the relevant network regions each year in time for changes to take effect from 1 January of the following year.
This letter specifies the wSSP and the RPI for the year 2018:
- These figures should be used to adjust transportation charges from 1 January 2019 in accordance to Special Condition 1 of the IGTs’ licences.
- The change in the weighted average of the relevant Gas Transporters’ single supply point charge.
The underlying calculations are described in appendix 1 of the letter.
