STC Energy Management - blue background


Starting 1st April 2018, DCP 161 is a new measure which has been introduced by Ofgem to ensure that half hourly (HH) supplies that exceed their assigned available capacity pay significantly more. It is a change to the DCUSA (Distribution Connection and Use of System Agreement) that will introduce excess capacity penalties for half hourly electricity supplies. This change will ensure that the additional costs that DNOs (Distribution Network Operators) can incur when customers exceed their available capacity levels are recovered.

Users who exceed their capacity will be charged an excess penalty rate which could be up to three times higher than the standard rate. The applicable rates will vary by region and voltage, with costs expected to be higher in areas where there is a higher demand for capacity. Depending on the consumption profile, if the supply regularly exceeds its assigned available capacity, this change could increase overall electricity costs by up to 1-2% or more.

Electricity meters that have been or are due to be converted to HH as a result of P272, will be settled on the HH market in time for the introduction of DCP 161.

STC Energy can assist you in the following ways:

  • Analysis of available capacity to establish whether an increase or decrease is required
  • Negotiate new capacity charges if your supply or capacity contracts are due for renewal between now and April 2018

  • Reducing your energy consumption to avoid excess charges
