Technical & management consultancy

The expertise that delivers

One firm, two specialist teams: technical due diligence on energy assets, and senior project management for organisations in any sector.

Our two practices
What we do

We advise on energy assets. We run projects for companies.

Two specialist teams, each with its own people and its own clients. Each is hired on its own, and each is signed by the person who did the work.

01 · Assets & investment

Energy

Independent technical judgement on the asset you are about to buy, build or refinance.

  • Technical due diligence: an independent read before you commit
  • Feasibility & business case: resource, layout, permits and grid
  • M&A support: acquisitions, portfolio deals and refinancing
  • Owner’s engineering & operations: from construction to performance

02 · Organisations & projects

Project management

Senior delivery capability for any organisation whose projects have outgrown its processes. Sector-independent.

  • Interim project management: a senior manager inside your team
  • PMO setup & handover: we build it, train the team, step out
  • M&A support: integration and carve-out delivery
  • Tooling, AI & process: built and running, not recommended

Pay for the expertise that delivers.

The expert you hire is the expert who does the work. No junior layer between you and the answer.

How we work

The people you hire are the people who do the work

YellowWatt was founded by senior specialists who came out of DNV, AFRY, Bureau Veritas and major EPC contractors. The person who reads your asset is the person who signs the report. Where a programme needs more capacity we bring senior associates under our own name and our own signature.

01

Senior execution

One senior specialist owns your engagement from the first call to the final page.

02

AI-assisted analysis

Collection and production run on an AI-assisted workflow. That is where the speed comes from; the judgement and the signature stay human.

03

International reach, local presence

We work internationally. In five countries we are also on the ground: Spain, Germany, the Netherlands, Italy and Türkiye.

Why we do it

Transforming energy for a sustainable future

Every asset we review and every project we run moves capital towards energy that lasts. We work where the decisions are made: on the array, in the substation, and in the room where the schedule slips.

Start here

Every relationship starts with a small piece of work

Two short engagements let you see how we work before you commit to anything larger. Scope and timing are agreed in writing before we begin.

You get a proposal within 24 hours. A Red Flag Review is typically delivered in five working days; a larger asset takes longer, and we say so before we start.
