Sites that want to reduce business energy costs this winter are starting from a harder place. Wholesale electricity in Ireland cost about 93% more in September 2026 than a year earlier, according to the Central Statistics Office (CSO) Wholesale Price Index. Other energy fuels rose by nearly half over the same period. Most sites typically feel this with a lag, as supply contracts roll over and fixed-price deals expire.
The question for an operations or energy manager is not whether costs rise. It is which loads to tackle first, and how to prove the savings when finance asks.
Picture a mid-sized dairy processor outside Cork
Take a typical site, used here as an illustration rather than a real company. It runs milk reception, pasteurization, cleaning-in-place (CIP) and cold storage. Refrigeration compressors and compressed air run around the clock. Steam comes from a gas-fired boiler, and hot water for CIP is heated from that steam.
On a site like this, electricity is usually dominated by a few motor-driven systems: refrigeration, compressed air, pumps and fans. Gas goes almost entirely to steam and hot water. That concentration helps. A handful of decisions can move most of the bill, which is why food, dairy and beverage sites often see results faster than they expect.
The higher price lands on refrigeration and compressed air first
Refrigeration is usually the first place to look. Condensing pressures set too high, defrost cycles on fixed timers and cold store doors left open all add load without anyone noticing. Compressed air comes next. Leaks and pressure set points chosen years ago are common, and air is typically one of the most expensive utilities on site.
The heat side has its own problem. The site pays for gas to raise steam, then pays again for electricity to reject heat through refrigeration condensers. Heat that leaves through a condenser or a boiler flue is heat the site has already paid for. Recovering it to preheat CIP water is a heat recovery design question, and one worth asking now.
An energy audit tells you which fix pays first
Price spikes push sites towards quick, visible actions. Some are worth doing. But without a baseline, nobody can tell a real saving from a mild month or a change in throughput.
A structured energy audit sets that baseline. It breaks consumption down by system, ranks measures by cost and payback, and shows where a bigger project could change the site’s energy balance. For smaller businesses that are not obligated to audit under Irish regulations, the Sustainable Energy Authority of Ireland (SEAI) Support Scheme for Energy Audits offers a €2,000 voucher towards an audit by a registered auditor, subject to eligibility.
A saving nobody can prove will not fund the next project
Cuts made this winter still have to show they worked. Without measurement and verification (M&V), savings disappear into the noise of weather, production volume and tariff changes.
Measuring against an adjusted baseline, to the International Performance Measurement and Verification Protocol (IPMVP), gives finance a number it can trust. It also builds the evidence a site needs for grant claims and sustainability reporting.
Check your contract date before the next bill arrives
The CSO index shows what the market is doing. Your supply contract decides when it reaches your site. Find the renewal date, then work back from it.
A site that knows its loads before it renegotiates can buy with more confidence and target the measures that cut exposure fastest. Our advisory team can help scope that first step.
Refrigeration, compressed air and steam typically decide most of a processing site’s energy bill. An audit before contract renewal turns a price shock into a ranked list of actions the site can prove.
