Plan Your Electricity Consumption and Save Money!

To keep your electricity bill under control, you can adjust your consumption habits based on price fluctuations:

• Do: Use your energy-intensive appliances such as washing machines, dishwashers and tumble dryers during the green-coloured times indicated above. This is also the best time to charge your electric car.
• Avoid: Periods between the red-coloured times shown above have the highest rate of the day.

It may also be possible to wait until tomorrow if the times that suit you better are cheaper tomorrow than today. The graph below compares today's and tomorrow's prices so that you can best estimate when to use electricity.

This approach helps you save on your bill and also contributes to better management of the electricity grid.

Why Do Electricity Prices Change Each Hour

Electricity prices are dynamic, changing based on a number of factors that constantly shift the balance of supply and demand on the power grid.

1. Demand: Prices rise during **peak demand periods**, when most people are using electricity at the same time. These are typically in the mornings and evenings when homes and businesses are most active. Conversely, prices are lowest during the night and early morning when demand drops significantly.
2. Supply: The cost of electricity is largely determined by the most expensive generator needed to meet demand at any given moment. In Ireland, this is often a natural gas plant. When demand is high, these more expensive "peaking" plants come online, driving up the price for all electricity.
3. Renewables:On the other hand, when there's a lot of renewable energy available, especially from wind farms, it significantly lowers the price. The marginal cost of generating electricity from wind is virtually zero, so when it's windy, it displaces the need for more expensive fossil fuel plants. This is why you often see lower prices on windy days.
4. Interconnectors:Ireland's electricity grid is also connected to Great Britain via subsea cables called interconnectors. These allow power to be imported from or exported to other markets. If prices are cheaper in Britain, we can import power, which helps to lower prices here. This also works in reverse, with Ireland exporting power when it's cheaper to generate it here. A new interconnector to France, the Celtic Interconnector, is also being developed to further link Ireland's grid to continental Europe.
