Founder

A new chapter, built on 24 years.

Founded after two decades inside European wind operations to give owners senior, independent advisory — from strategy through to execution.

From the nacelle to the boardroom.

Twenty-four years in wind. The early years were spent hands-on with the machine — turbine work in the field, in the nacelle, learning what fails, why it fails, and what it takes to put it back into production.

The second chapter was leadership of major corrective and lifting operations across European wind fleets — gearbox, generator and drivetrain campaigns, blade work, crane and lifting execution. The discipline that decides whether a fleet protects its design life or quietly bleeds value.

Today, founder of Kjær Wind-Advisory AB — putting that experience directly at the service of asset owners and operators, without the conflicts of interest that come with selling parts, services or contracts.

And — alongside the advisory work — co-owner of Econergi AB, operating a fleet of 12 Vestas V42 turbines. The same questions I work through with clients are the questions I sign off on for my own assets.

Leadership profile

Purpose-driven executive. Operator at heart.

A purpose-driven executive leader with extensive experience building and leading cross-cultural teams across the renewable energy sector — from field operations to the executive table.

Demonstrated success leading operational transformations of industrial and service organisations, with proven expertise in P&L management, operational excellence, and the building of a sustainable performance culture that outlasts any single contract or campaign.

Three convictions

What the work has taught me.

01

In-House is not only about reducing cost.

It is about competence, safety, control — and protecting long-term asset value. The cost saving is the consequence of doing the work properly, not the reason for it.

02

Operational control is built, not bought.

The right tooling, the right spare parts strategy, the right people — and the major component decisions made years in advance. None of it can be assembled in the 90 days before warranty ends.

03

Senior advisory means senior involvement.

Twenty-four years of operational experience, applied directly to your problem — from strategy to execution. The work that arrives on your desk was done by the person you briefed.

Technical Due Diligence

Independent, owner-side technical review.

I provide Technical Due Diligence for owners and investors who need a clear, operationally grounded view of an asset before they commit capital, approve a major component decision, or take a fleet in-house.

My role is to sit on the owner's side of the table — reviewing turbines, contracts, O&M history, spare parts strategy, and lifecycle risk from the perspective of someone who has operated the same machines and signed the same contracts.

Skin in the game

Co-owner and operator of a 12-turbine V42 fleet.

Through Econergi AB I am part-owner of a fleet of twelve Vestas V42 turbines — a long-life, post-warranty, in-house asset base. Spare parts strategy, tooling, major component decisions, lifecycle planning: not theory. Daily operating reality, with my own capital on the line.

When I advise an owner on transitioning away from OEM dependency, the recommendation is the same one I have already executed — and continue to execute — on my own machines.
