The Marinus Link project represents one of Australia\u2019s most ambitious energy infrastructure developments \u2013 a proposed 1,500 MW undersea and underground electricity interconnector between Tasmania and Victoria. Once complete, it will enable bi-directional flow of renewable energy across the National Electricity Market (NEM) and underpin Hydro Tasmania\u2019s \u201cBattery of the Nation\u201d initiative.<\/p>\n
The project reached financial close for Stage 1 in 2025, marking a major milestone in Australia\u2019s transition toward a cleaner and more resilient energy future. Given the project\u2019s scale, technical complexity, and cross-jurisdictional coordination requirements, independent project controls assurance was critical to support investor, regulatory, and parliamentary approval processes.<\/p>\n
Since 2023, TBH partnered with Marinus Link Pty Ltd to provide specialist time, cost and risk management services, helping to develop credible, evidence-based delivery plans that have underpinned key governance and funding decisions leading up to financial close.<\/p>\n

TBH was engaged by Marinus Link<\/strong> to provide integrated project controls expertise encompassing cost estimation<\/strong>, schedule <\/strong>development and quantitative risk analysis<\/strong> across multiple project phases and packages. The objective was to ensure alignment and confidence across the project\u2019s planning, regulatory and financial processes.<\/p>\n Cost Estimation and Review<\/strong><\/p>\n Integrated Master Schedule Development<\/strong><\/p>\n Quantitative Risk Analysis (QRA)<\/strong><\/p>\n Regulatory and Governance Assurance Support<\/strong><\/p>\n <\/p>\n TBH\u2019s integrated approach to time, cost and risk was fundamental to building regulator and financier confidence in Marinus Link\u2019s delivery strategy. TBH\u2019s alignment of cost, schedule and risk data \u2013 provided a clear, defensible line of sight between assumptions, contingency and delivery outcomes, enabling consistent, integrated project controls that reflected real-world delivery conditions. Early peer review improved cost realism and schedule credibility, ensuring the delivery plan reflected true construction sequencing and constraints. TBH\u2019s quantitative analysis directly informed governance bodies and financiers, demonstrating that the project\u2019s baseline was achievable and well understood. Drawing on decades of experience in energy, transmission and infrastructure megaprojects, TBH provided Marinus Link with confidence grounded in proven methodology and best practice. Through these contributions, TBH helped Marinus Link navigate critical milestones from concept validation to financial close \u2013 enabling Australia\u2019s next step toward a renewable, interconnected energy future.<\/p>\n","protected":false},"excerpt":{"rendered":" Project Overview The Marinus Link project represents one of Australia\u2019s most ambitious energy infrastructure developments \u2013 a proposed 1,500 MW undersea and underground electricity interconnector between Tasmania and Victoria.
