Who we are

Independent advice, on the owner’s side of the table.

RJI is an independent energy infrastructure advisory. We sit alongside asset owners, investors and funds rather than the supply chain, guiding major projects from acquisition and due diligence through FID, construction and into a live, earning asset.

We advise, manage and optimise. We are deliberately not the maintenance contractor. Our value is protecting your commercial position, reducing delivery risk and getting the most from every asset.

What we do

Three ways we protect and grow asset value.

01  Asset Management

Protect and recover revenue

Owner’s engineering, commercial management and contract administration across operating and construction assets. We drive O&M, OEM and EPC contractors to resolution and safeguard revenue.

02  Optimisation

Get more from every asset

Technical and commercial optimisation. OPEX and CAPEX modelling, value engineering, performance evaluation and energy transition integration to lift returns across the portfolio.

03  Consultancy

Reduce risk on the big decisions

Technical due diligence, feasibility, execution strategy, grid connection and project execution planning. The independent rigour funds and boards need before and through FID.
