Project Feasibility & Business Cases
Decision-focused feasibility and business cases that compare credible options, expose uncertainty and prepare boards, investors and funders for the next commitment.
Define the investment decision
A feasibility study or business case should answer a specific question: proceed, defer, reshape or stop. TDTEC starts by defining that decision, the alternatives that matter, and the standard of evidence required—not by producing a template document.
Work is informed by development and delivery roles on large renewable portfolios, solar and battery storage projects, hydrogen and ammonia prefeasibility, and board-level investment papers in the energy sector. Those experiences guide methodology; they are distinguished from TDTEC client deliverables unless the engagement says otherwise.
Compare credible options
Options must be comparable: similar boundaries, explicit exclusions, and assumptions stated so sensitivities can be run later. TDTEC structures option appraisals that separate strategic choice from implementation detail.
- Technology and layout alternatives within realistic constraints
- Delivery models—EPC, multi-contract, alliance or hybrid
- Staging and portfolio interactions where relevant
- Clear recommendation with conditions for proceeding
Technical feasibility and cost uncertainty
Technical chapters should state what is proven, what relies on supplier data, and what requires further study. Cost and schedule ranges should reflect known gaps—not single-point optimism.
- Design basis and study programme for the next gate
- Grid connection and infrastructure dependencies
- Major equipment and construction interfaces
- Contingency philosophy tied to identified risks
Economics, sensitivities and risk
Financial outcomes depend on engineering inputs. TDTEC integrates technical assumptions with economics and sensitivity testing, or works alongside your financial modeller with a shared assumptions register.
Detailed model build and investment advice boundaries are described on the project economics page. Feasibility deliverables focus on decision-ready summaries and the logic behind them.
Board and funding-ready deliverables
Deliverables are tailored to the audience: executive summary for directors, technical annexes for diligence, and evidence packs that can support funding applications where appropriate.
- Assumptions register with owners for update
- Risk register linked to mitigations and residual exposure
- Clear ask: capital, approvals effort or procurement trigger
- Defined follow-on work if the gate is passed
What is the difference between a feasibility study and a business case?
Feasibility tests whether options are technically and commercially viable under stated assumptions. A business case recommends a preferred option and seeks approval to commit resources. TDTEC scopes deliverables to the decision you need, which may combine both.
Do you follow Commonwealth or state business case frameworks?
Structure can align with familiar investment frameworks where the client requires it. Content remains project-specific; generic government templates are not substituted for substantiated analysis.
Can you support hydrogen or industrial energy feasibility?
Yes, where electrical and project delivery interfaces are material. Prior hydrogen and ammonia prefeasibility work in Queensland informs approach; each new project stands on its own evidence.
