Northern Ireland Electricity Pass through Charges 2019/20

Charges in your electricity contract include both the SSE Airtricity energy supply charges and Regulator approved Pass-Through Charges. As you can see in your contract, the SSE Airtricity energy supply charges will follow the agreed contractual risk management strategy e.g. fixed energy price, for the duration stipulated in the contract, and Pass-Through Charges will only change with approval by the Regulator.

The only differences in the charges set out below are the result of the Pass-Through Charges change, which have been approved by the Regulator for 2019/2020.

The Pass-Through Charges applied by NIE Networks, System Operator for Northern Ireland (SONI) and the Single Electricity Market Operator (SEMO) for the 2019/2020 period have now been set, and the changes to your contract prices are noted below. There are a few additional charges introduced via I-SEM and these are also shown below.

The net adjustments will be applied to your bill from 01 October 2019.

What are Pass-Through Charges?

Electricity Suppliers in Northern Ireland pay multiple different regulated charges and levies which they in turn must pass on to their customers through their billing and rates. Regulated charges for the use of the electricity distribution and transmission network in Northern Ireland and a levy known as the Public Service Obligation (PSO) are set by NIE Networks and the System Operator for Northern Ireland (SONI) and the maximum amount recoverable is approved by the Regulator. Other regulated costs, including capacity payments, are associated with the Integrated Single Electricity Market (I-SEM) and are set by the Single Electricity Market Operator (SEMO) and the maximum amount recoverable is set by the SEM Committee. Usually NIE Networks, SEMO and SONI set these charges, and the Regulator approves the charges, on an annual basis.

Pass through charges are applied equally to all suppliers.

Pass-through charges include

  • Transmission Use of Systems (TUoS)
  • Distribution Use of Systems (DUoS)
  • Public Service Obligation (PSO)
  • System Support and Services (SSS)
  • Supplier Capacity Charges price
  • Difference payment socialisation Multiplier
  • Residual Error Volume Price
  • Currency Cost price and currency Adjustment charge factor
  • Collection Agency Income Requirement (CAIR)
  • Market Operator Charges (MO)
  • Imperfection Charges
  • Northern Ireland Renewable Obligation (NIROC)
  • Availability charges
  • Standing Charge
  • Reactive Charge
  • Demand Capacity Charge*
*Customers who have demand capacity charge as pass-through within their contract.

How will the changes in pass-through costs impact my premises? 

The level of Pass-Through Charges applicable to your premises and the change in these costs from 01 October 2019 depends on Use of System (UOS) Code linked to your premise(s) which is explained on your advisory letter. All supply points connected to the electricity network have a connected UOS code. The UOS code is assigned by NIE Networks to the premise based on the network connection characteristics and metering configuration.

Dependent on the UOS code for the premise(s), the net adjustment to your current rates from their current level are detailed in the table below. 

SSE Airtricity’s pricing proposal set out the Pass-Through Charges that were used to calculate the tariffs. For any customers now coming towards the end of their contract term, the renewal quotation will reflect the 2019/2020 Pass-Through Charges and we won’t need to further update your bill.
