Executive Viability Abstract
This feasibility study evaluates the establishment of a utility-scale ocean wave power generation plant along the southern coast of Australia. Given Australia's world-class wave resource, particularly in the Southern Ocean, the project demonstrates high technical potential and strong alignment with national decarbonization goals. While capital expenditures remain high compared to solar or wind, the consistency of wave energy and strategic government support provide a viable path to commercialization by 2030.

## Market Analysis
Australia possesses one of the world's most energetic wave resources, with the potential to contribute up to 11% of the national energy mix by 2050. The global ocean energy market is projected to reach $20 billion by 2030, with a CAGR of 18%. In Australia, the shift away from coal-fired power creates a gap for predictable baseload-style renewables. Competitive advantages include high energy density and low visual impact compared to offshore wind.
## Capex Summary
Total estimated Capital Expenditure for a 50MW pilot plant is AUD $185 million. Major cost drivers include:
- Wave Energy Converters (WECs): 45%
- Subsea Cabling & Grid Connection: 20%
- Installation & Marine Logistics: 20%
- Project Development & Permitting: 10%
- Contingency: 5%
## Revenue Model
The revenue model is based on a tri-fold stream:
1. Power Purchase Agreements (PPAs) with industrial off-takers at a premium 'green' rate.
2. Sale of Large-scale Generation Certificates (LGCs) under the Australian Renewable Energy Target.
3. Spot market electricity sales during peak demand periods when wind and solar output may be low.
## Financial Projections
With a Levelized Cost of Energy (LCOE) projected to drop from $250/MWh to $120/MWh over the next decade, the project targets a positive cash flow by Year 7. Initial phases rely on ARENA grants to offset high upfront technical risks.
## Risk Assessment
Key risks include the harsh marine environment (corrosion and storm damage) and the nascent supply chain for specialized WEC components. Environmental impact on marine ecosystems is rated as a moderate risk requiring long-term monitoring.
