THE FINANCIAL CASE

What a 99 kW + BESS System Does to Your Bill.

Indicative. Based on Ergon BUSN tariff + typical demand charges for a 3-phase industrial site.

Grid energy drawn8,400 kWh / qtr
Network charges$1,840
Peak demand charge$2,100
Quarterly total$8,950
Solar self-consumption72% of load
Remaining grid draw2,352 kWh / qtr
Peak demand (BESS reduced)↓ 40%
Quarterly total (est.)$2,580

Indicative only. Exact analysis provided in your free feasibility study based on actual interval meter data.

THE BUSINESS CASE

Every kWh Bought from the Grid Is Profit Leaving the Site.

The cost drivers
  • Commercial Ergon tariffs include peak demand charges that inflate bills regardless of duration
  • Air conditioning and refrigeration in QLD summer adds 30–50% to quarterly bills
  • Grid energy costs increased 25–35% in three years with no reversal forecast
  • Battery storage reduces both energy costs and peak demand charges simultaneously
The commercial opportunity
  • Commercial systems qualify for instant asset write-off under current ATO provisions
  • LRET and LGC incentives reduce the effective cost of systems above 100 kW
  • Green energy credentials increasingly required for government supply contracts
  • Solar infrastructure increases asset value and reduces operational costs permanently

THE PROCESS

From Initial Data to Energised System.

Four stages. Managed under one contract by our Mackay-based commercial team.

1
Load Data & Feasibility

We analyse 12 months of interval meter data, tariff structure, and network constraints. Full feasibility report within 48 hours — at no cost.

2
Engineering Design

CEC-accredited engineers produce a site-specific design: string layout, DNSP export limits, protection scheme, civil and structural drawings.

3
Installation

Mackay-based commercial crew. DNSP-approved grid connection and metering. Typical 100 kW system: 3–5 days. Minimum disruption to operations.

4
Monitoring & Reporting

SCADA-grade monitoring. Monthly energy and savings reports. 10-year workmanship warranty. Local support team on call.

SCOPE OF SUPPLY

Everything Under One Contract.

From feasibility to energisation — no third parties, no coordination gaps.

Commercial & Industrial Arrays

Rooftop and ground-mount systems from 30 kW to 1 MW+. Structural engineering and waterproofing warranty included.

Battery Energy Storage (BESS)

Commercial BESS from 30 kWh to multi-MWh. Demand management, grid arbitrage, and backup power configurations.

DNSP Grid Connection

Full network application management, protection relay settings, metering upgrades, and Ergon/Energex approval documentation.

SCADA Monitoring

Real-time production, consumption, and export data. Monthly savings reports delivered automatically. Anomaly alerting included.

Finance & Incentive Structuring

Commercial lending, operating lease, and PPSA structures. LGC, LRET, and instant asset write-off analysis in your feasibility report.

O&M — Ongoing Maintenance

Scheduled preventive maintenance agreements. Inverter health monitoring. Cleaning programmes for high-soiling environments.

WITH NEXT PHASE SOLAR

  • Single-contract scope: design to energisation
  • Mackay-based project team — no interstate crews
  • DNSP application and approval managed by us
  • LGC, STC, and government incentive maximisation
  • 10-year workmanship + manufacturer warranties

WITHOUT SOLAR

  • Grid energy costs increasing 8–10% per annum
  • Peak demand charges increase with business growth
  • No depreciation or tax benefit from energy spend
  • No hedge against future electricity price increases
  • Competitors with solar operating at lower cost bases

FAQ

Frequently Asked Questions.

System size is determined by your actual load data, available area, network export limits, and financial objectives. We analyse interval meter data from the past 12 months. Typical commercial installations in Mackay range from 30 kW to 300 kW.
All commercial systems require network (DNSP) approval from Ergon Energy or Energex. We manage the full application process on your behalf. Approval typically takes 4–10 weeks depending on system size. We factor this into the project timeline from day one.
Systems below 100 kW receive STCs deducted from your invoice. Systems above 100 kW receive Large-scale Generation Certificates (LGCs) on an ongoing basis. The federal instant asset write-off allows deduction of the full cost in the year of purchase — confirm eligibility with your accountant.
Commercial Ergon tariffs include peak demand charges based on the highest 30-minute interval measured in the billing period. A BESS can discharge during peak demand windows, capping the measured demand and reducing the charge applied to the entire billing period — often 20–40% of total bill savings.
Commercial solar can be financed via chattel mortgage, finance lease, or operating lease. For qualifying projects, $0-upfront power purchase agreement (PPA) structures are available through our finance partners. We provide a financing comparison in the feasibility report.
