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.

Business electricity unit prices may be cheaper than domestic ones because of the amount of energy used, but most business customers pay a higher rate of VAT.

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

What are Pass-Through costs?

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.

What is the PSO Levy for business customers?

The Public Service Obligation Levy (PSO) is mandated by the Irish Government and approved by the European Commission to support the generation of electricity from sustainable, renewable and indigenous sources.

The levy is calculated and certified annually by the Commission for Regulation of Utilities (CRU) in accordance with relevant legislation and all energy suppliers are required to collect this levy from customers. For further information please visit

What are the PSO levy rates for business customers?

The amount of PSO you pay for your business premises is based on your Maximum Import Capacity (MIC). 

The current PSO levy rates for businesses from 1 October 2020 are:

  • PSO where MIC < 30kVA = €21.41 per month 
  • PSO where MIC => 30kVA = €2.78 per kVA per month


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.
