Business tariffs and price plans explained

How does business energy pricing work?

Business energy prices and plans are calculated and set up differently to domestic ones.

Pricing is based on your business size and electricity consumption. It may be calculated on a fixed or a variable rate tariff.

If you have a quarter-hourly meter, we'll give you a tailored price based on when and how you use electricity.

For more information on Pass Through Costs for business electricity customers, see the And for latest publications on charges, see the CRU publications.

What is the PSO Levy for business customers?

The Public Service Obligation (PSO) is mandated by the Irish Government and approved by the European Commission. Due to current electricity market price trends and volatility a higher PSO payment will be required in 2024/2025. Given the relatively smaller payment that would be due to customers for the coming PSO year 2023/24, the CRU has decided to use this to mitigate some of this volatility. This will result in the PSO levy being set to zero from 1 October 2023 to 30 September 2024.

For further information please visit

The PSO rates for businesses from 1 October to 30 September 2024 are:

  • PSO where MIC < 30kVA = €0
  • PSO where MIC => 30kVA = €0

Fixed Term plans

  • Guarantees the unit price for a set period of time
  • Plans usually run for between 12 and 24 months

Standard Variable plans

  • Unit prices can go up or down, but are typically costlier than fixed-term rates
  • You can give notice to switch to another plan or supplier by giving us 30 days' notice.

Deemed plans

  • Usually the most expensive business electricity tariffs
  • Speak to your supplier and you should be able to switch from deemed rates within a short period of time

What are Pass-Through costs?

Pass-Through costs are set by ESB Networks / EirGrid / SEMO (TUoS, DUoS, Market Operator, Imperfection Charges) and approved by the Commission for Regulation of Utilities (CRU), this includes charges associated with Use of System costs and usually happens in October. This means that Unit Prices and Standing Charges above are subject to change when Pass-Throughs change. This will not affect any discount you have.

Here is a breakdown of what exactly makes up the Pass-Through Costs on your bill:


Capacity Payments

Payment to generators for availability separate from energy production.

Market Operator Charges

Charges applied to generators and suppliers for the operation of wholesale markets.

Imperfection Charges

Charges applied to recover constraint costs on the network.


Network Transmission use of system charges (TUoS)

Charges for building, maintaining and operating the transmission network.

Network Distribution use of system charges (DUoS) 

Charges for building maintaining and operating the distribution network.

For more information, see the latest Information Paper from the CRU.


The integrated Single Electricity Market (i-SEM) is a new Europe wide energy market that replaced the Single Energy Market (SEM) on the 1st October 2018. It has been introduced to harmonise cross-border trading arrangements and create a more active and dynamic energy marketplace across Europe.

Bord Gáis Energy has been preparing for this new system for the last five years, investing heavily into redesigning our IT infrastructure and making substantial organisational changes to ensure we continue to meet the energy needs of our consumers. 

The Energy Trading Team will be closely monitoring how i-SEM impacts the energy market over the coming months and will use these insights to identify ways to offer even better value to our customers.

Switching your business to Bord Gáis Energy

It’s easy to switch business energy supplier; it should be completed within four weeks and your new supplier should do most of the leg work.

What if I'm tied into an existing contract?

Consult your terms and conditions as it's possible that you may not be able to switch contracts for a set period of time. Your contract may mean you have to pay a charge if you want to leave it before the end date. Check to make sure any savings you'd make aren't cancelled out by any contract penalties.

If you're tied into a deal, make a note of when the lock-in period is about to come to an end and call us for a quote at that time.
