Commercial Electricity Contract Customers: Notification of Pass-Through Charges Change

Commercial Electricity Contract Customers: Notification of Pass-Through Charges Change

The unit price (i.e. the kilowatt hour (kWh) rate) SSE Airtricity charge you in your electricity supply contract includes both the SSE Airtricity energy charge and regulated pass-through charges. Our SSE Airtricity energy charge will follow the agreed contractual risk management strategy which means a fixed energy price, for the duration outlined in your contract. It also means pass-through cost will only change with approval by the Regulator, the Commission for Regulation of Utilities (“CRU”).

The pass-through charges charged by ESB Networks, Eirgrid and the Single Energy Market Operator (SEMO) for the 2019 - 2020 period have now been approved by the regulator, and the changes to your contract prices are detailed below.

The changes will be applied to your existing prices for consumption from 1 October 2019.

There will also be a decrease in PSO levy for 2019/20, which has now been confirmed by the CRU. This will lead to a decrease in charges for all customers as you can see below.

What are Pass-Through Charges?

Pass-through charges are the charges that all electricity suppliers must pay other organisations in the Integrated Single Electricity Market (ISEM) when supplying electricity to customers, like those that we receive for the use of the ESB Networks and Eirgrid’s systems. Usually, ESB Networks and Eirgrid set these charges, subject to regulatory approval (i.e. the CRU), on an annual basis.

Pass-through charges (which are described in the attached glossary) include:

  • Transmission Use of Systems (TUoS);
  • Distribution Use of Systems (DUoS); 
  • Market Operator Charges; 
  • Imperfection Charges;
  • Supplier Capacity Charges
  • Electricity Tax
  • MIC charges*;
  • Standing Charge*;
  • Low Power Factor surcharge*;
  • PSO levy*; and
  • VAT*.
  • The Integrated Single Electricity Market (I-SEM)
* - these are shown as separate charges to your kWh tariffs on your bill.

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

The level of pass-through charges applicable to your premises and the change in these charges from 1 October 2019 depends on the DUoS Group or “DG” number. All supply points connected to the electricity network have a DUoS Group. The DUoS Group is assigned by ESB Networks to the premises based on the network connection characteristics and metering configuration.

Dependent on the DUoS Group for the premise(s), the overall adjustment to your current rates from their current level can be seen in the table below.

How do I Identify my “DG” number?

The DUoS Group your site belongs to can be located at the top right-hand corner of your bill.

This is identified by the code:

  • DG1 & DG2
  • DG3 & DG4
  • DG 5
  • DG 6
  • DG 7
  • DG8
  • DG9
  • TCon

Once you have this information you can see the relevant changes in the pass-through charges for your premises listed below.

Public Service Obligation (PSO) Levy: Decrease Cost for 2019/20

The public service obligations (PSO) levy relates to the purchase by ESB of the output of certain peat generated electricity, in the interests of security of supply, and the output of certain generating stations using renewable, sustainable or alternative forms of energy, in the interests of environmental protection, in accordance with a Public Service Obligations Order made pursuant to the Electricity Regulation Act 1999.

ESB is required by the Irish government to make these purchases in the interests of security of supply and environmental protection. The levy is used to recover the additional costs to ESB and other suppliers in having to source a proportion of their electricity supplies from such generators.

Statutory Instrument No. 217 of 2002 (as amended) made under Section 39 of the Electricity Regulation Act 1999 requires that the Commission for Regulation of Utilities (CRU) calculates and certifies the costs associated with the PSO and sets the associated levy for the required period. This is done during the summer and resultant levy then applies from the 1 October. In some years (such as 2008) the PSO amount is small and the levy is set to zero.

The CRU has calculated the payment by customer category for the levy period 1 October 2019 to the 30 September 2020 to be as follows:

Customer Category Levy Amount(Per Annum) Levy Amount / Month % from 2018/19
Small Commercial Customers (MIC < 30kVA) €124.20/customer €10.35/customer -14%
Medium and Large customers (MIC ≥ 30kVA) €14.64/kVA €1.22/kVA -8%

Glossary of Terms

Pass-through costs

Pass-through charges are the costs that all electricity suppliers must pay other entities in the Electricity Market when supplying electricity to customers such as those incurred for the use of the ESB Networks distribution and transmission systems.

Transmission Use of System (TUoS)

These are the costs all electricity suppliers pay Eirgrid to transport electricity from the generating station through the transmission grid to the distribution system (or to the customer’s site for the small number of customers connected to the transmission system). The transmission system is the high voltage system for the bulk movement of electricity. The charge, which is set by Eirgrid, is called the Transmission Use of System (TUoS) tariff and is regulated by the CRU.

Distribution Use of System (DUoS)

These are the costs all electricity suppliers pay ESB Networks to transport electricity through the distribution system to a customer’s site. The distribution system is the local part of the network that serves the customer. The charge which is set by ESB networks is called the Distribution Use of System (DUoS) tariff and is regulated by the CRU.

The Integrated Single Electricity Market (I-SEM)

The Integrated Single Electricity Market (I-SEM) is the wholesale market for Ireland and Northern Ireland. The previous market arrangements have been replaced since 1st October 2018 by multiple markets or auctions, each spanning different trading time frames, with separate (although related) clearing and settlement mechanisms, covering both energy and non-energy commodities.

System Market Operator (SMO) – Market Operator Charge

This covers the cost of the development and operation of the Integrated Single Electricity Market (I-SEM). The cost is shared across all electricity suppliers and generators on the island of Ireland. It is a flat charge per unit on loss adjusted consumption. The charge, which is set by SEMO, is called the Market Operator Charge and is regulated by both The Utility Regulator in Northern Ireland and the CRU in Republic of Ireland.

Imperfection Charge (IC)

Actual dispatch on the all-island transmission network differs from the optimal dispatch derived for the market schedule. This is because constraints are introduced due to network bottlenecks (including the North South Interconnector) and due to the need for the system operator to maintain reserve for operational security. The wholesale energy “system marginal price” calculated in the market is the lowest possible price that the electricity required on the island of Ireland could theoretically be generated at (if there are no constraints). It ignores the limitations of the transmission network and is calculated with perfect foresight. As generators are obliged to sell into the I-SEM, they are guaranteed not to operate at a loss (variable costs only). The imperfections tariff covers the gap between the market price and the cost of dispatching generation in real time into a market where constraints in practice do exist. The charge, which is set by SEMO, is called the Imperfection Charge and is regulated by both the CRU and the Utility Regulator (NI).

Supplier Capacity Charge Price

This charge covers the capacity cost of the generators in the I-SEM. It is published by SEM Committee and approved by both CRU and Utility Regulator (NI).

Other charges

Maximum Import Capacity (MIC) charge or Capacity Charge

MIC is measured in kiloVolt Amperes (kVA). It is the level of electrical capacity, which represents the maximum load you are contracted to import from the electricity network for use in your premises. Significant penalty charges normally apply if you exceed this level.

Standing Charge

Daily standing charges are a combination of the fixed charges associated with providing electricity and gas network services and a share of the supply costs in servicing your account.

Electricity Tax

Government imposed tax on electricity supply.

Low Power Factor Surcharge

The low power factor surcharge applies to all ‘Wattless Energy ‘(kilovolt amperes hours (kVArh)) recorded in any billing period if the metered kVArh is more than one third of the metered kWh in any billing period. The charge is only applicable to the kVArh in excess of one third of the kWh.
