Energy & Sustainability

Helping energy operators, utilities, and sustainability-led enterprises navigate the transition — with the capex discipline, regulatory fluency, and carbon-accounting rigor it demands.

The energy transition is no longer a strategy slide; it is a capex programme. The operators we work with are running parallel businesses — a legacy hydrocarbon book that funds the transition, and a new renewables and grid-services business that needs to scale faster than the legacy depreciates. The hard work is keeping both honest on cost, carbon, and capital allocation.

Challenges We Address

Three recurring themes in energy & sustainability work

Transition

Energy-transition strategy

Portfolio reshaping, capital reallocation between legacy and new energy, and the operating-model design to run both well at once.

Capex

Capex efficiency

Large-program cost discipline — EPC contracting strategy, supply-chain de-risking, and the analytics to spot drift before it compounds.

Carbon

Carbon accounting & disclosure

Scope 1–3 measurement that survives audit, transition-plan disclosure aligned to ISSB and CSRD, and the data foundation behind both.

Three principles for energy work

01

Capital discipline above all

The transition is a capital-allocation problem. Every recommendation is tested against the marginal capital cost of the alternative.

02

Carbon math that survives audit

Design carbon-accounting systems to the standard the auditor will sign — not the standard the marketing team prefers.

03

Run two businesses at once

The legacy book funds the transition. The work helps teams operate both with the same management discipline.
