  1. Part of the Babcock & Brown Infrastructure Group DUoS Billing of IDNOs

  2. Overview • IDNOs to date. • DNO Requirements. • Arrangements for supplier billing • Data for operational arrangements. • IDNO Billing Proposal • Losses

  3. History to date • Utilities Act introduced competition in distribution. • SSE first DNO to establish embedded networks. • P62 implemented on 1 August 2003. • First Distribution Licences granted in Autumn 2004. • ENC’s distribution licence granted July 2006.

  4. DNO Requirements DNOs need: • To identify units entering and exiting their distribution system. • By Customer group • By Voltage level • To recover DUoS income in accordance with regulatory price control. • Information to operate their distribution system

  5. Arrangements for Supplier Billing • Exit and Entry Points registered in SMRS. • Suppliers responsible for collecting data and passing to settlement. • Settlement data passed to DNO: • Aggregated by LLFC/PC/SSC/TPR for NHH supercustomer. • Separately for NHH site specific. • Separately for HH. • Data is not corrected for losses.

  6. IDNO Billing Proposal • IDNO sets LLFCs so that each LLFC identifies: • the voltage of connection to the end consumer; and. • the voltage of connection to the Upstream Distributor • IDNO can provide settlement data by voltage of connection to DNO network. • Additionally IDNOs can provide: • data from meter reading flows. • customer types connected to each connection point.

  7. Example of IDNO LLFCs

  8. Losses • Price Control • DNO losses incentive £48/MWh. • Increased losses reduce distributed units. • Losses at each voltage level per dwelling

  9. Recovery of losses • DNOs have ability to recover value of electricity taken other than in pursuance of a supply contract. (Paragraph 4, Schedule 6 of the Electricity Act 1989). • DNOs required to make a scheme for determining the quantity of electricity taken.

  10. In summary… IDNO proposaloffers a solution which: • enables DNO to recover price control income. • provides data in the same form as the DNO receives from settlement. • provides data in the same form as the DNO has for operational management.
