Protect your margins from volatile energy costs.
Stop paying for wasted energy. We deliver investment-grade energy audits and ongoing management programs that unlock government funding and permanently lower your operating costs across New Zealand and Australia.
Turn energy waste into capital investment.
Energy prices are unpredictable, and grid volatility is increasing. For heavy industry, manufacturing, and commercial sectors, treating electricity, gas, and coal as "fixed costs" is no longer viable. If your site is running inefficiently, a significant percentage of your monthly utility bill is essentially OpEx waste—you are paying for energy that never makes it into your final product.
At DETA, our accredited energy transition consultants help you find that waste, eliminate it, and build the business case to fund major upgrades. We don't just hand you a list of engineering ideas; we deliver a financial roadmap. By identifying immediate efficiency savings, we help you free up the cash flow needed to fund your larger CapEx decarbonisation projects.
