FOR WIND OWNERS AND OPERATORS

The wind is changing - know before you budget.

Wind patterns across Europe are shifting, and not every site is affected the same way. See which of your sites are losing yield, which are gaining, and where to buy or build next.

Within 48 hours, you'll see how your sites' last two years compare with 75 years of wind history.

THE PROBLEM

13 of 15 European wind markets ran below their long-term average in 2025.

A single weather pattern drove it, and German wind yield ended 15% below its average. 2026 has fallen short again for many sites. Now the 2027 budget is due, and most teams fall back on one of two defaults: the long-term average, or the average with a few percent shaved off, and both are guesses. Get it wrong and you're explaining another miss next year - or you've cut a budget, and a valuation, that didn't need cutting.

Example: year-by-year outlook for one site

Yield of one example wind site, 1985 to 2045Forty years of yearly yield versus the long-term average, ending in two weak years, followed by a widening range of likely outcomes to 2045. Illustrative example.-6%-4%-2%0%+2%+4%1985199520052015202520352045Peak yearsLast 40 yearsRange aheadTwo weak years
Forecasts based on the strong 2000s can overstate future yield. Illustrative: one site's possible path. Your sites may look different, and that's what we model.
WHAT YOU GET

Plan, build and price based on the wind you'll actually get.

Outcomes

  1. 01

    A realistic P50 and P90

    A bankable P50 assumes, by design, that future wind will look like past wind. Ours shows how the wind at your sites is shifting, year by year - per site and across the portfolio, in your convention (P50, P75 or your own index).

  2. 02

    The wind resource, split out

    How much of a shortfall came from the wind resource itself, and how much from operational and market losses: outages, curtailment, prices.

  3. 03

    The wind systems you depend on

    Which weather patterns drive your sites, and which sites have their good and bad years together.

Example

Know which wind systems your portfolio depends on.

Sites in different countries can still have their good and bad years together, because the same weather patterns drive them.

One wind portfolio under four wind patterns Nine wind sites spread from Spain to Denmark under four wind patterns: under NAO+ the northern sites gain and the southern ones lose, under NAO- the reverse, and under the two Scandinavian patterns every site moves the same way.

North gains, south losesThis portfolio is spread from Spain to Denmark, yet one wind pattern can move every site at once. Illustrative example, not client data.
WHO IT'S FOR

For owners & investors

Future-proof your investments.

  • Climate-adjusted IRR per asset and across the portfolio
  • Year-by-year yield outlook for the portfolio
  • Which of your sites have their bad years together, and which balance them
  • Where new assets would balance your portfolio - for any region in Europe, or a specific wind farm you want to buy

For operators

Future-proof your business model.

  • Stress-test your revenue assumptions against the wind ahead
  • Benchmark your P50/P75 against a climate-adjusted, year-by-year outlook: realistic values to plan and measure against
  • When a site underperforms, see which part was the wind resource and which was operational or market losses
  • Check your positioning: do your sites have their weak years at the same time?
HOW WE WORK

Your question, our scientists, one clear answer.

Tailored solutions, built by PhD climate scientists, accelerated by AI.

A University of Hamburg spin-off, with scientists from the Climate Service Center Germany (GERICS), the Potsdam Institute for Climate Impact Research (PIK), the Max Planck Institute for Meteorology (MPI-M) and the University of Potsdam.

  1. 1

    We start from your question: a budget, a site, an acquisition.

  2. 2

    We build the answer with your numbers: 75 years of wind history and a forward view of where wind patterns are shifting, reconciled with your own figures - as a custom application or data fed into your own models.

  3. 3

    We stand behind it: we turn the findings into decisions with you, at your board or investment committee.

It starts with a 30-minute intro call about your question.

USE CASES

Proven on real wind portfolios.

We've supported 26 clients across renewable energy, utilities, manufacturing and infrastructure investment.

Wind owner · 700 MW portfolio, Central Europe

Two weak years: a cyclical dip, or something structural?

We modelled each asset from 1985 to 2060 and traced the shortfall to a shared Atlantic wind system, not geography.

Result: A revised investment plan, with new capacity redirected to sites whose good and bad years don't coincide with the rest.

Infrastructure investor · 48 MW wind farm, Northern England

A wind farm on the market at £48M: what was it really worth?

Our forward-looking analysis corrected yield and insurance assumptions that had been treated as static.

Result: A fair value of £62M: +29% upside and a +700 bps IRR uplift.

FAQ

Common questions.

How does it work?

We start with an intro call about the decision in front of you: a budget, a site, an acquisition. Within 48 hours you see how your sites' last two years compare with 75 years of wind history. From there, we build the answer with you.

What do I need to provide?

Site locations and turbine types are enough to start; we go through them together in the call. More detail makes the answer more precise, but we work with what you have.

Which assets do you cover?

Our focus is European wind. We've also worked across renewable energy, utilities and manufacturing.

What does the output look like?

Delivered where you already work: usually a custom application built for your team, or data fed straight into your own models. Per site and month, in your convention: P50, P75 or your own index.

How long does it take?

The historic comparison takes 48 hours after our call. The timing for the full analysis depends on your portfolio, and we agree it upfront.

We already track this in-house.

We give you a forward number for the budget, reconciled with your own tracking.

Wind is only part of the miss.

That's why we focus on the wind part: once it's right, what's left is clearly operational.

We budget on P75, not P50.

Then we give you P75.

Is this about climate change in 2050?

It's about the years to come: a realistic range, built on 75 years of wind history.
