See every watt, then shift it.
We instrument your site down to the circuit, map demand against tariff windows, and translate raw telemetry into a costed roadmap for load-shifting, storage sizing and grid-aware control that pays for itself.

An energy audit at NexusCore is not a clipboard walkthrough. We deploy interval metering and sub-metering across major loads, then ingest twelve months of your network operator data to build a high-resolution demand profile. That profile reveals the hidden geometry of your consumption: when peaks land, which assets drive demand charges, and where consumption collides with the most expensive tariff windows. From that baseline we model exactly how much spend is structural versus recoverable, and we quantify the upside of shifting flexible loads off-peak before a single panel or battery is specified.
The Australian energy market punishes poor timing. Demand charges, time-of-use rates and critical peak pricing mean two sites with identical kilowatt-hour totals can pay wildly different bills. Our auditing isolates this timing premium so you can attack it directly. We separate base load from controllable load, identify candidates for automated curtailment, and stress-test how rooftop generation and battery storage would reshape your net position across summer and winter extremes.
What the audit measures
- Half-hourly interval demand mapped against your retail and network tariffs
- Demand-charge drivers and the specific assets creating monthly peaks
- Load-shifting potential for HVAC, pumps, refrigeration and process loads
- BESS sizing scenarios with depth-of-discharge and cycle-life modelling
- Power factor, harmonics and reactive-power penalties hiding in your bill
From data to a costed roadmap
Measurement only matters if it changes decisions. Every audit closes with a ranked list of interventions, each carrying an estimated capital outlay, annual saving and simple payback. We model how solar generation, battery storage and tariff switching interact, because the value of one depends heavily on the others. A battery that looks marginal on arbitrage alone often becomes compelling once demand-charge reduction and grid-service revenue are stacked. We show you that stacked case explicitly so capital flows to its highest-return use first.
Grid-aware and future-proof
We design audits with the next decade in mind, not just this quarter. As more sites participate in virtual power plants and demand-response programs, the ability to flex load on signal becomes a revenue stream rather than a constraint. Our reporting flags where your loads could be enrolled in grid services and what controls would be required to capture that value safely, keeping operational priorities untouched.
Start with visibility, then act with confidence. Book a NexusCore energy audit and convert a year of invisible waste into a funded, sequenced plan for independence.
Energy Auditing questions
On-site instrumentation typically takes one to two days depending on site complexity, followed by a monitoring window so we capture real demand cycles. We then analyse the data and deliver your costed roadmap, usually within two to three weeks of metering completion.
No. Many clients audit first precisely to decide whether solar and storage make sense. The audit quantifies your load profile so any future generation and BESS investment is correctly sized rather than guessed, which protects your return and avoids costly oversizing.
Minimal disruption. Our metering clamps onto existing circuits and runs passively in the background. We schedule any brief isolation work around your operational windows, and the monitoring phase requires no changes to how your site normally runs day to day.
Load-shifting moves flexible consumption into cheaper or solar-rich periods. Because Australian tariffs charge heavily for peak-time demand, shifting even part of your load can cut bills substantially. The audit identifies which loads can move and models the saving before you commit.
