Energy & Decarbonisation Engineering — Tauranga & Bay of Plenty

In 2026, energy isn't just a utility bill—it is a strategic risk to your margins. With wholesale peak prices frequently exceeding $500/MWh, 'business as usual' is becoming a liability. At DETA, we bridge the gap between boardroom sustainability targets and factory-floor realities. From the massive forestry processing plants in the Bay to the complex energy profiles of Tauranga’s public sector and food production hubs, we provide the investment-grade engineering required to de-risk your operations and ensure your projects are technically flawless and financially viable

LOCAL CASE STUDY

Tauranga Hospital – energy audit & efficiency improvements

DETA carried out a detailed Type 2 Energy Audit for Tauranga Hospital to identify ways to reduce energy use, operating costs, and emissions across the facility.


Through on-site assessments and data analysis, our engineers identified 257 MWh of potential energy savings with a payback period of under five years. The recommended projects would deliver an estimated $45,000 in annual savings and cut emissions by around 285 tonnes of CO₂ each year.



This project highlights how DETA’s Tauranga team helps public and private sector clients achieve measurable, cost-effective energy and carbon reductions.
