Most industrial sites are bleeding energy through outdated tariff structures, uncontrolled peak demand events, and equipment running at part-load inefficiency. An Apex Grid energy audit does not produce a PDF that sits in a drawer. It produces a ranked capital-investment schedule with projected IRR, payback, and emissions abatement for every measure identified — structured so your finance team, board, and grid connection application can all draw directly from the same dataset.
What an Apex Grid Audit Covers
We instrument your site with sub-metering across high-consumption circuits for a minimum 30-day baseline capture period. Data is mapped against your network tariff to identify avoidable demand charges, time-of-use misalignment, and power factor penalties. The output is a facility-wide energy model benchmarked against industry intensity metrics.
- ASHRAE Level I–III audit methodology scaled to industrial and infrastructure sites
- Half-hourly interval data analysis against network tariff structures including demand, TOU, and capacity charges
- Power factor correction and reactive power opportunity identification
- Compressed air, refrigeration, and HVAC system efficiency benchmarking
- Solar-plus-storage sizing recommendations derived from actual load profile data — not rule-of-thumb estimates
- LGC and REGO-eligible generation modelling integrated with NMI data
- Carbon accounting under NGER and Scope 1/2/3 frameworks
From Data to Capital Decision
Audit findings feed directly into our PPA and financing desk. Where the audit identifies solar or battery storage as high-return measures, our advisory team can model a behind-the-meter PPA structure, a grid-scale BESS procurement, or a hybrid self-consumption arrangement — all stress-tested against wholesale price volatility and network tariff escalation assumptions. You are not buying a report. You are buying a decision framework.
Apex Grid audit teams carry both electrical contractor licences and energy assessor credentials. Every recommendation is backed by engineering sign-off, not software-generated estimates. Clients operating under safeguard mechanism obligations or voluntary net-zero targets receive additional scope covering embodied carbon and renewable certificate strategy aligned with their disclosure obligations.
Deliverables and Standards
Final deliverables include an executive summary, detailed measure register with capital cost and payback schedules, a 25-year cash flow model at P50 and P90 irradiance scenarios, and a board-ready investment brief. All audit work is conducted in accordance with ISO 50001:2018 and is designed to integrate with your existing ISO 14001 environmental management system. We do not recommend measures we cannot engineer and deliver.
