What annual capex budgeting really costs, and what replacing it is worth
For leaders of capital portfolios in energy and critical infrastructure.
The thesis. Annual capex budgeting feels like control. In reality it consumes capacity, distorts cash flow and holds back value. In the middle of the largest investment cycle this industry has seen, that makes it the most expensive habit in the company.
What the status quo costs.
- 13% of capacity lost to planning. In one reference case, 200 people spent 13 percent of their time over several months preparing feasibility estimates: 26 full-time equivalents consumed by planning alone.1
- 20 to 40% of preparation effort wasted. That share of proposed initiatives never passes the funding threshold. The work invested in them produces nothing.2
- More than a quarter of prioritised projects cancelled anyway. In one large organisation, more than a fourth of the projects placed above the funding line were later cancelled once conditions changed.2
- Cash flow that defies steering. The typical pattern: 3 to 4 percent of the budget spent in the first month, more than a third rushed out in the last.1
These are not delivery failures. They are artefacts of the governance model itself.
The design flaw. Adding planning rigour makes it worse. Pressure to deliver in time and budget leads rational managers to pad their estimates. Padded estimates make projects more expensive, and more expensive projects mean fewer of them get funded. Meanwhile, research found that 97.3 percent of board proposals get approved: the real decisions are taken elsewhere, long before the board meets.1
The alternative: envelopes. Instead of approving dozens of individual projects once a year, leadership allocates funding to five to ten strategic envelopes: grid resilience, decarbonisation, connection growth, asset renewal. Each envelope has one accountable owner with real decision rights. The governing question changes from “which projects do we approve?” to “is this envelope delivering its value?” The model is published: van der Pas and Boudreau, “A New Paradigm for IT Budgeting,” CIO Magazine, June 2026. → Download the full CIO Magazine article (PDF)
The infrastructure reality: money is not the constraint. In capital portfolios the binding constraint is execution capacity: engineering hours, crews, outage windows, supplier slots. A funded project that cannot be staffed is the most expensive form of misallocation. Envelope governance therefore needs a capacity gate: resources are committed before funding is, and no envelope commits to more than it can deliver.
What you gain.
- Roughly a tenth of organisational capacity returned from planning to delivery.
- Funding that follows value continuously: companies that actively reallocate capital are worth about 40 percent more after 15 years and deliver roughly 30 percent higher annual returns to shareholders.3
- Metrics your board and your regulator accept: NPV per envelope, NPV-to-capex, asset lifecycle performance aligned with ISO 55000.
- Commitments that hold, because every funded initiative has passed the capacity gate.
