DCP161 - Excess Availability Charges

Important Changes to your Electricity Availability Charges - Action Required

Industry wide change DCP161 – Excess Availability Charges

We’re writing to inform you about industry-wide changes that will affect how your electricity is billed and the action you now need to take. Currently, if your business uses more than its agreed DUoS Availability, which is the value (expressed in kVA) agreed between you and your Distribution Network Operator (DNO)*, you are charged for the Excess Availability at your standard rate. This charging structure is set to change in April 2018.

From 1st April 2018, DCP161 - Excess Availability Charges are being introduced. From this date, if you use more than your agreed DUoS Availability you will be charged at a higher rate for the excess; this is known as agreed DUoS Excess Availability or Excess Capacity**. Please note this change only impacts half hourly metered electricity supplies with current transformer metering.

Your DNO may have already contacted you about this change. It has been estimated that the excess charge will be up to three times higher than standard rates so may have a significant impact on your bill if your DUoS Availability is set too low. You can find out what the new DUoS Excess Availability rate is on your DNO’s website. If you’re not sure who your DNO is, refer to the ‘How to identify your DNO’ section overleaf which also contains contact details.

Next actions we recommend you take

  1. Find your current agreed DUoS Availability
    Review your past 12 months’ bills to understand whether excess charges have been applied. This information
    can be found in the ‘Other Charges and Adjustments’ section of your bill.
  2. Review whether your DUoS Availability is sufficient
    If you have incurred Excess Availability charges within the past 12 months, or think that your Availability is insufficient for your current or future needs, then you should contact your DNO to adjust your agreed DUoS Availability as soon as possible.
  3. If necessary, contact your DNO to change your DUoS Availability
    To find your DNO, refer to the ‘How to identify your DNO’ section below. Contact details for your DNO have been supplied on a separate sheet.

For any enquiries or changes to your DUoS Availability, please contact your DNO. For any other enquiries regarding your bill, please contact ENGIE Customer Services on 0113 306 2151.

DCP161 is an industry change that will be affecting a large number of sites in the UK and can take time to update.

Please note, an increase in your agreed DUoS Availability means an increase in your on-going standard DUoS Availability charge. Therefore, you should assess whether it would be more beneficial to increase the agreed DUoS Availability or to pay excess charges for the number of times you anticipate exceeding it.

** A Capacity/Availability charge covers the peak energy requirements for each Meter Point Administration Number (MPAN). The Availability charge is expressed in pence per kVA per day where kVA is the peak allowance as agreed between you the customer and the Distribution Network Operator (DNO) in your connection agreement. An excess Capacity/Availability charge applies when the agreed DUoS Availability monthly demand is breached. DUoS Excess Availability charge may also be levied by the DNO when the monthly maximum demand exceeds the agreed DUoS Availability.

 

How to identify your DNO

1. Find your Distribution ID on your Metering Point Administration Number (MPAN). Your MPAN can be found
at the top of your bill or on your electricity meter (Diagram below).
2. Search for your Distribution ID on the DNO look-up table below for their contact details.
In the example below the Distribution ID is 10 which means that the corresponding DNO is UK Power Networks.
