Background to the Irish Electricity Market

The Irish Electricity Market is based on a central pool system where power stations all bid into a central market. The energy price that power stations are paid changes ½ hour by ½ hour and a forecast is published by the market operator 24 hours in advance. This is known as the System Marginal Price (SMP) and is shown in Blue on the graph.

However, other charges are associated with managing and transporting the electricity from the power station to the end user. These are;

DUoS (light Green) - Distribution Use of System charges - (38kV and lower, Network charges)

TUoS (Gold) - Transmission Use of System charges - (110kV & higher, Network charges)

SEMO (dark Green) - Single Electricity Market Operator charges - (Market operator, manages the electricity pool and is commercial interface between power stations and suppliers

Capacity Costs (Red)- Power stations are paid for providing a backup called a reserve (both spinning & static) in case demand is higher than forecast or another power station trips and power is needed urgently. This is shown in the Red part of the graph above and averages out at about 1.8c/kWh. It can vary between 0 and about 3.5c/kWh during the winter peak.

DLAF & TLAF (Calculated into Charges) - Distribution & Transmission Loss Adjustment Factors, depending on the connection level and day/night divide, some of the charges above are multiplied by a loss adjustment factor. This is of the order of 9% for Low Voltage (400v) sites and 4 % for Medium Voltage (10kV and higher) sites.

SmartPower aggregates the different charges and loss adjustment factors associated with each type of connection and publishes this as a web-service to the Echelon SmartServer controller that we provide.

The market operator publishes forcast prices every day, we download them and present them here with the other kWh charges that you would expect to pay. The "greyed out" portion of the table below, is our estimate on what these costs will be based on a weighted average taken over the past number of years.

Why not join our Procurement Group Scheme?

The SmartPower procurement group uses our inside knowledge of industry pricing practises to negotiate cheaper electricity and gas prices for clients who are members of our procurement group. We monitor market developments to ensure that you always get the most competitive price in the market. We advise you of opportunities to save money by switching suppliers or changing tariffs as market conditions develop. It is free to join the group as there are no direct fees or any obligation to buy.There are no contracts or restrictions. You can be a member of the group but maintain your current direct supplier relationships if preferred.

SmartPower awards the business to suppliers who offer both exceptional value for money and flexibility to allow our clients lock in tariffs at the appropiate times. The fee that we recieve directly from the supplier comes out of the supplier mark-up, so there is no cost to you. Best of all, we ensure that difficult to understand bills hiding high supplier markups are a thing of the past....
