Lifting the day-to-day burden of ownership, so you can focus on creating value.

For non-operating investors leading the energy transition, with £100m - £10bn in assets under management.

Trusted by leading investors

The energy transition depends on investors leading the way.

Investors carry the investment risk, buy most cannot justify building the same depth or breadth of capability needed to maximise the potential of their portfolios.

If the energy transition is going to succeed for future generations, everyone needs to win. Not just those large enough to justify utility-grade capability of their own.

We've seen first hand, the impact that lack of the right resources was having on investors in the energy transition. Namely: poor returns and lack of performance due to their senior people drowning in low-value work, chasing, coordinating, escalating and firefighting.

Energy transition assets are more demanding of owner time, than other infrastructure investment classes.

To extract the best performance from energy transition assets, investor teams should be laser focused on the things only they can do. The workstreams that deliver the most value - decisions, strategy and value creation. 

We give investors deep expertise across every aspect of ownership: commercial, technical, governance and optimisation.

We lift the day-to-day ownership burden for investors, so they can focus on strategic priorities, not the busy work. 

Investors get the capability of a utility, without becoming one.

The uncomfortable truth

Most investors in the energy transition are forced into a false choice.

Either way, the day-to-day burden is on you.

Your team is pulled into the weeds. So, progress slows, problems surface later and value is left on the table.

  • 2.3 GW of renewables projects under advisory
  • £2 billion + in portfolio value managed
  • 6 GW + of cumulative renewables experience

Independent by design.

We do not operate assets, we are not owned by an investor, and we work for you alone. 

Your alternatives are to build the function in-house, appoint a non-executive with a board seat and a quarterly meeting, or bring in a generalist consultancy on day rates. We are none of those things.

Our Mission

To deliver an accelerated, value-creating energy transition - by helping renewable asset owners manage their investments more effectively.

We exist to give clients their time back, plug value leaks, and capture new opportunities for performance improvement.

Everything we do is practical, data-led, and human - grounded in insight, partnership, and a genuine commitment to the long-term success of the energy transition.
