Practice · Energy and infrastructure
Energy and infrastructure.
This is the first practice area we name. It is a calibration of the same closed diligence workflows — direct investment, co-investment, operational and secondary review — to a class of asset where the return is decided by documents a generalist process reads straight past.
A buyout memorandum lives in the operating model. An infrastructure deal lives in the power agreement, the interconnection study, and the credit of the counterparty on the other side of the offtake. The finding that moves the return is usually in a document the marketing book does not lead with, and often in one it quietly contradicts. What follows is what we read on these assets, and what we read it against. It is a sector calibration of the existing workflows, not a new one — the artifact is the same cited, reviewed memorandum, shaped for an infrastructure committee.
The interconnection section below is the short version. The long version — what a queue position is and is not, and the restudy that moves the cost — is the first Letter.
Interconnection and queue position
A queue position is a place in line for a set of studies, not a right to connect and not a cost. We read where the project sits, which studies have actually run — feasibility, system-impact, facilities, and any restudy — and whether it was studied for energy service or for firm network service, which are different products with different upgrade obligations. We separate the project’s own interconnection facilities, which are fixed, from the shared network upgrades, whose cost reassigns when other projects in the cluster withdraw. The document that carries the answer is rarely the deck; it is the most recent grid-operator letter, and the work is reading it against the schedule the model assumes.
The power agreement
The offtake is where the revenue is either real or assumed. We read the tenor against the debt and the useful life, the price mechanism for what it does in the scenarios the model does not show — a fixed price, an indexed one, a hub reference that leaves the project carrying the basis to its own delivery point. We read the curtailment terms for who bears lost output when the grid cannot take it, and the offtaker’s credit for whether the counterparty will still be investment grade in the year the contract matters most. A signed agreement with a weak counterparty and an uncapped basis is a different asset from the one the summary describes.
EPC and the interconnection agreement
Construction and connection are governed by two contracts that have to be read together. In the EPC we read the milestone and liquidated-damages structure, the caps, and where cost-overrun and force-majeure risk actually sit. In the interconnection agreement we read the same milestones from the grid’s side — the schedule to energisation, the security to be posted, and the allocation of network-upgrade cost, including who absorbs it if an upgrade is reassigned. The two schedules are supposed to agree. When they do not, the gap is the risk, and it is usually the interconnection schedule, not the EPC, that sets the date the project can actually earn.
Storage augmentation
A battery is not a fixed asset; it is a depreciating one with a maintenance schedule the model has to carry. We read the degradation curve the warranty guarantees against the throughput the revenue case assumes, the augmentation schedule for when capital has to be spent to hold contracted capacity, and the warranty terms for what voids them. The common error is a revenue model that cycles the battery harder than the warranty allows, so the augmentation the operator will actually owe arrives earlier and larger than the plan. The question is whether the contracted capacity is held across the life of the offtake, and at what cost.
Power availability for data centres
For a data-centre asset the binding constraint has moved from space to power, and the diligence follows it. We read contracted capacity against available capacity — what the utility has agreed to deliver, and by when, against what the site actually needs at full load — and we read the redundancy commitment for whether it is designed or merely described. Efficiency figures such as PUE matter only against a contracted power position that stands behind them. Siting sits underneath all of it: the entitlements, the water for cooling, and the same interconnection question every other project on this page turns on. A campus with a signed tenant and no firm power is a lease against a building that cannot yet run.
Nuclear and SMR licensing
Small modular reactors have entered the infrastructure conversation ahead of any settled diligence standard for them. Here the workflow reads the licensing posture — where a project stands with the Nuclear Regulatory Commission, which pathway it is on, and what remains before it — alongside the third-party construction-cost review and the offtake that is meant to underwrite a very long build. This is the one area where the output is explicitly a draft: an orientation for the committee and its counsel, marked not advice, and routed for human review the way the tax brief is, never returned as a regulatory conclusion.
None of this is a separate product. It is the same closed, single-tenant diligence, calibrated so the workflow knows where this class of asset hides its risk and reads for it. The memorandum it produces is the one your investment committee, your lawyers, and your auditors can sign.
The other sector calibrations: sector fixtures.
