Real solar economics are complex and project-specific. This page compiles verified benchmarks from CSIRO, the Clean Energy Council, AEMO and the Clean Energy Regulator so you can start with facts, not guesswork.
Sourced from the CSIRO GenCost 2024–25 Final Report — Australia's authoritative annual review of electricity generation capital costs.
These are general cost component categories described in industry literature — not fixed percentages. Your project's split will differ based on scale, location and technology.
Typically the largest single cost category. Australian import logistics and compliance testing add cost versus overseas benchmarks. CEC maintains an Approved Products List for grid-connected equipment.
Can range from modest to project-defining. Remote sites may require kilometres of new transmission and substation upgrades. Always obtain a formal Connection Enquiry from your network service provider (NSP) early in planning.
Site preparation, fencing, access roads, foundations, electrical reticulation and commissioning. Australian labour costs are higher than many comparable markets. Utility-scale construction typically takes 6–18 months.
EIS preparation, EPBC referrals, community consultation, state planning applications and council engagement. Timelines vary widely — from months in supportive jurisdictions to years in contested areas.
Legal, financial modelling, insurance, project management, contingency and debt/equity financing costs. ARENA and CEFC can provide concessional finance for eligible projects, reducing overall cost of capital.
Rural land leases for solar in Australia generally range $600–$1,500/ha/yr, depending on location, developer competition and project size. Typical terms are 20–25 years. Actual rates are commercially negotiated.
Revenue depends on project structure, contracts negotiated, grid location and technology. Most utility-scale projects rely on a combination of the following.
| Revenue Stream | How It Works | Verified Reference Data | Source |
|---|---|---|---|
| Power Purchase Agreement (PPA) | Fixed-price contract with an energy buyer for a set volume of generation. Provides revenue certainty and underpins project finance. | Terms typically 10–25 years. PPA pricing is commercially negotiated and confidential — public benchmarks are limited. | AEMO ISP 2025; CEC |
| NEM Wholesale Spot Market | Revenue from real-time electricity dispatch through AEMO. Can be combined with financial hedges (caps, swaps) to manage price volatility. | 2024 annual averages: QLD ~$86/MWh, NSW ~$82/MWh, VIC ~$57/MWh. Highly variable year to year. | AER State of the Energy Market 2024 |
| Large-scale Generation Certificates (LGCs) | One LGC created per MWh of accredited renewable generation. Sold to liable entities (retailers) to meet RET obligations. | LGC spot ~$45–47 mid-2024, declining toward RET's 2030 end. Future post-RET certificate framework subject to policy. | CER QCMR Q2 2024 |
| Capacity Investment Scheme (CIS) | Federal Government scheme providing floor/ceiling revenue underwrites for new renewable generation and storage. Reduces revenue risk. | Expanded in 2024 to cover entire NEM. Target: underwrite 32 GW of new renewable capacity by 2030. Amounts negotiated via competitive tender. | DCCEEW / AEMO CIS Framework 2024 |
| Australian Carbon Credit Units (ACCUs) | Eligible projects generate ACCUs for emissions avoided or sequestered. Sold on the secondary market or via Government Carbon Abatement Contracts. | Spot ~$35/tCO₂-e (early 2025). Total Government ACCU commitments: ~$22.6B (CER). Safeguard Mechanism covers 261+ facilities creating structural compliance demand. | CER Q4 2024 QCMR |
| FCAS & Ancillary Services | Solar-plus-storage projects can provide Frequency Control Ancillary Services (FCAS) to AEMO. Requires battery co-location and market registration. | FCAS market has grown competitively as more BESS enters. Market size and prices vary by service type and region. | AEMO FCAS Market Reports; AER |
| Small-scale Technology Certificates (STCs) | For systems under 100kW — provides upfront point-of-sale discount funded by the RET scheme. | STC deeming period reduces annually to 2030. Current zone ratings and clearing house prices on Clean Energy Regulator website. | Clean Energy Regulator STC Register |
