Challenge
Vulcan steel had little visibility into energy usage at their site in Auckland. The site wanted assistance in sustained reductions in consumption and better data to make informed future investment decisions.
Solution
ESP installed sub-metering system followed by a Type 1 energy audit at the Auckland site identifying opportunities to improve machine utilisation, reduce compressed air usage, and upgrade lighting.
Outcome
This engagement has resulted in 25% savings in the first year alone. This was achieved with better shift management to double production levels from baseline year. The factory has also upgraded their lighting to LED. Vulcan Steel continues to engage ESP in tariff negotiation at other sites.
