The Blueprint
One month, fixed fee, scoped to your portfolio.
An independent baseline of your portfolio and how it is run, a prioritised roadmap with the value at stake on each item, and how we would run it.
Trusted by leading investors
Investors stopped buying renewable exposure and started owning renewable assets.
The operating question came with it.
It used to be answered by default, because the fund manager answered it for you. Then subsidy regimes rolled off, portfolios moved into merchant exposure, warranties expired and the cost of capital rose, narrowing the gap between the return underwritten and the return realised.
- IEA: Between 20% and 50% of the levelised cost of a utility-scale solar project is the cost of capital alone.
When capital costs more, management carries more of the return.
We are very pleased to be moving forward in our relationship with NIA. Our goal is to always ensure our offshore wind assets are operating at the highest levels of efficiency and extracting maximum value.
We welcome NIA’s specialist support as an added layer of expertise, and look forward to continuing this valuable partnership into the future
Two ways to start. One way of working.
Speed. Value. Delivery.
Asset Management Partnership
From co-source alongside your team to fully outsourced, with a single point of accountability across four lenses.
Implemented in full inside six months, and you are free to leave on a month's notice throughout year one.
Renewables OS
How both are delivered.
Our system for running renewable assets: the five foundations every owner needs, plus an always-on operating loop. It is how we work, not a product you buy.
Special Projects
Not every challenge fits an ongoing mandate.
Our Special Projects deliver focused, high-value support for assignments requiring specialist expertise or rapid turnaround.
Each project is built around a clear objective, scope, and timeline - providing practical, data-led solutions to complex commercial or operational issues.
Typical areas include:
- Transaction and due diligence support
- Performance and compliance reviews
- JV structuring and alignment
- Portfolio strategy
- Claims and disputes management
These represent our typical project areas - we also support fully bespoke assignments. Please get in touch to discuss your specific requirements.
Our Impact
Control. Clarity. Confidence.
Trusted by leading renewable investors to deliver control, clarity and confidence when it matters most.
- 2.3 GW of renewables projects under advisory
- £2 billion + in portfolio value managed
- 6 GW + of cumulative renewables experience
- £4 billion + in transaction and divestment support
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.
