Calculation of Flogas Energy Tariffs

The energy tariffs are calculated based on the following costs:

• Pass through costs
• Wholesale energy costs
• Supplier costs

Pass Through Costs

Pass through charges are the charges that all electricity and gas suppliers must pay other entities when supplying electricity and natural gas to customers, such as those incurred for the use of ESB Networks’ and EirGrid’s systems for electricity and Gas Networks Ireland for natural gas. 

Some elements are not Flogas charges, these are market charges. Usually, ESB Networks and EirGrid set these charges for electricity and Gas Networks Ireland set them for natural gas. These are then subject to regulatory approval by the Commission for Regulation of Utilities (CRU), on an annual basis.

Here is a breakdown of what makes up the pass through costs on your bill:

Electricity

Generation

• Capacity Payments: Payments made to electricity generators for availability separate from energy production.
• Market Operator Charges: Charges for the operation of the wholesale market.
• Imperfection Charges: Charges applied to cover the costs of constraints on the electricity network.
   

Network

• Transmission Use of System Charges (TUoS): Charges for building, maintaining and operating the electricity transmission network.
• Distribution Use of System Charges (DUoS): Charges for the building, maintaining and operating the electricity distribution network.
   

PSO

• Public Service Obligation (PSO) Levy: A Government mandated levy to support the generation of electricity from sustainable, renewable and indigenous fuels.
   

Natural Gas
 

Network

• Gas Networks Ireland Transmission Tariffs for the operation of the transmission network.
• Gas Networks Ireland Distribution Tariffs for the operation of the distribution network.
• UK Transportation Costs for the cost of transporting gas from the UK to Ireland.
   

Balancing

• Charges associated with the balancing and distribution of gas on the system.
   

Natural Gas Carbon Tax

• A tax levied on natural gas by Irish Tax and Customs.
   

Wholesale Energy Costs

These costs reflect the cost to purchase energy on the wholesale energy markets. Wholesale prices vary throughout the year and are influenced by many factors such as supply, demand, geopolitical and macro-economic factors, weather, commodity prices and exchange rates.

Supplier Costs

These costs are based on costs associated with operating as an energy supplier and serving customers in the market.
