Price influencers

There are several components that make up the total cost of your bill. Suppliers must take all of these into consideration and package them into any offer to customers (see our Jargon Buster for more details):

  • Energy – the wholesale pool price of electricity (Latest Price Trends in the Single Electricity Market)
  • Use of System – paid to the network operators for the use of their poles, wires and cables
  • Capacity – generators are paid for being available to supply the market
  • PSO (Public Service Obligation)
  • SSS (Systems Support Service)
  • Imperfections
  • NIRO (Northern Ireland Renewables Obligation)
  • Market Operator charge
  • Supplier margin
  • CCL (Climate Change Levy)
  • VAT
