Wholesale electricity prices, which is the price suppliers pay, fell by more than 16% in the year to September, according to latest figures from the Central Statistics Office.
The CSO also said that between August and September the monthly fall in the wholesale price of electricity was 2%, while prices are 75.6% lower when compared with the peak in August 2022.
The latest fall in wholesale prices comes after a report last month from the International Energy Agency (IEA), which found that energy retail prices in Ireland are three times higher than wholesale prices.
According to the IEA, the gap between what energy providers pay on the wholesale market and what they charge customers for the same energy is one of the highest in the world.
The sustained fall in wholesale electricity prices also comes despite most of the main energy companies announcing significant price hikes for customers in the past month.
Today's CSO figures also show that producer prices for food products fell by 0.2% from August but are up 4.5% in the year since September 2024.
Some of the most notable changes in producer prices for food products were dairy products, with prices jumping by 11.1%, while meat and meat products rose by 7.1%.
The CSO said that overall wholesale price inflation showed a decrease in September with a 0.4% decline in the overall Producer Price Index for manufacturing industries.
It noted that producer prices for products sold on the domestic market were 1.2% higher in September from the same time last year.
In the 12 months to September 2025, export producer prices fell by 3.1% and are at their lowest since October 2021, while overall producer prices were down by 2.6%, the CSO added.
