At a glance

Creganna Medical deployed Advisor for comprehensive energy monitoring across precision manufacturing operations — balancing the strict process-quality requirements of medical-device production with energy efficiency and cost optimisation. The result was a 27% reduction in annual energy spend, achieved without compromising the controlled conditions the process depends on.

01The brief

Efficiency without compromise

Medical-device manufacturing runs to exacting standards. Cleanroom conditions, controlled environments and validated processes mean energy is intrinsic to product quality — you cannot simply turn things down to save money. Any efficiency programme has to work within those constraints, not against them.

Creganna needed comprehensive visibility of where energy was being used across precision operations, so that savings could be found in the right places — without touching the conditions that quality depends on.

02What we did

Comprehensive monitoring, targeted savings

Advisor gave Creganna a complete picture of energy use across operations, so efficiency measures could be aimed precisely — at the consumption that didn’t affect process quality.

In precision manufacturing you can't trade process quality for savings. So we measured first, and cut the spend the data exposed — never the spend that mattered.

03The outcome

A 27% saving, quality intact

By monitoring energy comprehensively and targeting only the consumption that didn’t bear on product quality, Creganna cut its annual energy spend by 27% — proving that even in a tightly controlled medical-device environment, there is meaningful efficiency to be found when you can see the data clearly.

The win wasn’t just the number: it was a method for finding savings that respects the constraints of regulated manufacturing, and can be applied again as operations evolve.
