Commercial Due Diligence & Transaction Support
Technical-commercial review of assumptions, contracts and delivery exposure for energy and infrastructure acquisitions, investments and major commercial decisions.
Commercial assumptions linked to engineering
Investment cases often treat engineering outputs as fixed inputs. Commercial due diligence tests whether revenue, cost, schedule and performance assumptions still hold when the underlying technical evidence, study maturity and delivery plan are examined together.
TDTEC focuses on the technical-commercial thread: what the plant or asset must do, what the contracts require, and where gaps create price, delay or performance risk. This is not a substitute for financial modelling or legal review; it informs them with engineering-grounded findings.
Delivery and contract exposure
EPC, EPCM, OEM, O&M and connection agreements allocate risk through technical schedules, warranties, LDs and interface definitions. Review concentrates on whether scope, performance criteria and remedy paths match the actual system boundaries and known delivery constraints.
- Performance and availability assumptions versus equipment and integration reality
- Warranty, defect and remedy interfaces across multiple contractors
- Change, delay and force majeure exposure tied to studies and long-lead items
- Operating and maintenance assumptions after handover
Acquisition review and investment decisions
Support is available for buy-side and sell-side preparation where technical-commercial issues could affect valuation, conditions precedent or post-close integration. Scope aligns with the transaction timeline and the questions that would change the deal structure or price.
Where a parallel technical due diligence stream is required, TDTEC can run integrated or complementary workstreams with clear boundaries between engineering risk and commercial terms. Technical due diligence addresses material technical risk; this service emphasises how that risk sits in contracts and the investment narrative.
Specialist adviser interfaces
Transactions rely on legal, tax, insurance, market and financial advisers. TDTEC interfaces with those teams by translating engineering findings into commercial language and by testing whether contract drafts reflect agreed technical positions.
TDTEC does not provide tax due diligence, legal due diligence, accounting audit or market research. Those disciplines remain with qualified specialist firms; this engagement fills the technical-commercial layer for energy and infrastructure assets and projects.
Findings and negotiation support
Outputs are written for decision-makers and negotiation teams: material exposures, recommended clarifications, and points that belong in conditions, warranties or price adjustments. Findings are ranked by consequence and by whether they can still be addressed before close or financial close.
Negotiation support can include review of counterparty responses, technical evaluation of contract departures, and preparation of engineering-backed positions for your commercial and legal advisers — without TDTEC acting as legal counsel.
Prior commercial negotiation experience on major energy programmes informs how findings are structured; outcomes for your transaction depend on scope, evidence and the parties involved.
Is this full commercial due diligence including tax and legal?
No. TDTEC provides technical-commercial assessment for energy and infrastructure projects. Tax, legal, market and financial due diligence should be led by the appropriate specialist advisers.
Can this run alongside technical due diligence?
Yes. Scopes can be integrated or parallel, with shared data-room planning and distinct reporting lines so engineering risk and contract exposure are both visible to the decision-maker.
Who typically instructs this work?
Developers, owners, investors, lenders and corporate development teams preparing for acquisition, divestment, refinancing or major contract award on energy and infrastructure assets.
