For years, the business model of a renewable energy trader was simple: find customers, run a weather forecast, sell power on the Day-Ahead market, adjust in Intraday, collect the fee. If you could do that, you had a business. If you could do it well, you had a good business.
That era is over.
Not because the craft has gotten harder — quite the opposite. The classic renewable energy trading process has become a commodity. Margins are thin, the algorithms are good, the market is consolidating. What has changed is the environment: the energy market is making demands that the old model simply was not built to meet. Those who don't evolve will be pushed out.

What renewable energy traders have done until now — and why that's no longer enough
The classic renewable energy trading model grew out of a very specific world: assets under the EEG (Germany's Renewable Energy Act) subsidy scheme, stable price expectations, a clear mandate. An asset owner with 15 MW of wind or solar needs someone to take their power into a balancing group, produce a daily forecast, adjust deviations in Intraday, and handle the balancing energy settlement with the transmission system operator. For that, they pay a fee — typically around €2 per MWh, depending on portfolio size and location.
That's not a trivial business. But it's one that many companies now execute very well. Better weather models, automated trading algorithms, scaled back-office processes: what once required real expertise is now highly standardizable. Anyone offering only this service is competing in a market with very thin margins and a great deal of competition. Differentiation is getting harder by the day.
Consolidation is already well underway. Most independent renewable energy traders are now part of large utilities or oil companies — Total, Shell, EnBW, RWE. Citadel FlexPower was itself a long-standing independent player before becoming part of Citadel. Scale matters — and not just in execution, but especially where the classic renewable energy trading model runs into its structural limits.
Three forces breaking the business model
Structured products and PPAs require a balance sheet
The Ukraine crisis of 2021/22 revealed something that had previously seemed only theoretical: when front-year prices climb from a then-normal €100 to at times over €1,000 per MWh, asset owners want to lock in those prices. Not for 20 years — but perhaps for one, two, or three. And right now, with the current market environment shaped by the conflict in the Middle East, that impulse is very much alive again.
The problem: a short- to medium-term PPA covering several hundred megawatts can easily reach a notional value of €100 million. No compliance department will sign off on taking that kind of counterparty risk against a renewable energy trader with a balance sheet of ten million euros. Regardless of how good the service is.
Then there are structured power products on the offtake side: think delivering solar power during defined hours directly to an industrial customer, simultaneously, regionally, with a guarantee of origin. That's exactly what data centers like Google are looking for — not just green power, but green power at the moment of consumption, sourced from the region. Delivering that product requires a risk and structuring desk capable of pricing the exposure, hedging it, and credibly holding the position over years. That, too, is a function of balance sheet and trading capabilities.
Anyone who only covers the generation side and routes power straight to the exchange can offer neither.
Co-location and batteries require a different level of competence
Barely a PV developer today plans a new utility-scale installation without battery storage. That means the growth segment of the market is going to be almost exclusively accessible to players who can market both assets together.
In most cases, this is not even a matter of preference — it's regulatory. Co-located batteries and solar installations sit behind a single meter. They cannot be split between two separate marketers.
But the leap from wind and PV marketing to battery marketing is substantial. Batteries require trading algorithms that optimize continuously across balancing power and Intraday markets on a fully automated, 24/7 basis — with a complexity level several orders of magnitude above the standard forecast-and-Day-Ahead routine. And that doesn't yet account for the interdependencies: when a grid connection constraint, a PPA behind the meter, and optimized battery dispatch all have to be coordinated simultaneously, you are dealing with an automation challenge that most pure renewable energy traders are simply not equipped to handle.
Balancing power is becoming a baseline requirement
Balancing power markets remain largely closed to wind and solar assets in Germany — but in other European markets, that has long since changed. And the opening will come here too. A renewable energy trader who today lacks the ability to access balancing markets will not be able to accompany that transition well.
For a co-located battery storage system, roughly 30% of revenue potential comes from balancing power markets. Any marketer who cannot offer this access is simply not capturing a significant share of the asset's value — a structural problem for any installation that does not receive government support.
Post-EEG: The overlooked growth segment
Alongside these three structural pressures, another issue is emerging that carries significant market consequences: post-subsidy assets. For onshore wind alone, installations totaling 11.3 GW of installed capacity had already lost their EEG support payments by mid-2025 — and that share keeps growing year by year. These assets continue to generate power, but without the price certainty the EEG provided for years. Many of their owners built their businesses precisely on that certainty and have correspondingly little experience carrying price risk themselves. The obvious answer is a PPA — but here too, not every renewable energy trader is the right partner. Offering a post-EEG wind farm a fixed price for three years means being able to hedge and hold that risk. Offering an asset owner an automatic curtailment product for hours when power prices fall below zero — a product in high demand in the post-EEG context — requires both a reliable algorithm and 24/7 operational capability that many smaller firms do not have. The bar for what a marketing partner needs to deliver has risen substantially, for post-subsidy assets just as much as for anything else.
From service provider to risk manager
Perhaps the most profound shift is not a product question — it is a cultural one.
A classic renewable energy trader thinks of itself as a service provider: good service, low costs, stable fee margin. The model is designed for continuity, not for volatility. And that is precisely where the risk lies — because the power market is volatile by nature.
The Ukraine crisis demonstrated this starkly. Balancing costs that had been calculated at €1.50 per MWh spiked to €7–8 per MWh during the crisis. Anyone who had modeled a margin of €0.50 was suddenly hit with €6 in additional costs. Direct marketers without an active trading desk had no way to profit from the rise in volatility on the other side of their book — and therefore no natural buffer.
A modern trader thinks in terms of risk positions as a structural matter: what risks am I carrying, in what market environment do I benefit, how do I hedge when one side of the portfolio is under pressure? That question is not answered once a year — it is answered every day. That requires people, not just algorithms. Power markets are too erratic, too driven by short-term events, for purely systematic models to keep pace consistently. Our experience is clear: a desk staffed by human traders — 24/7, across multiple markets — outperforms purely algorithmic systems in this discipline.
For asset owners, this is not merely an academic question. A renewable energy trader holds its customers' revenues for months — and often pays out two months later. Anyone who wants to make sure their money is safe should ask: can this partner survive a real market crisis?
A new name for a new role
"Renewable energy trader" was never a particularly precise term — it describes a process, not a competency. What the market needs today, and will need still more tomorrow, is something different: power traders and risk managers who can operate on both sides of the market, offer structured products, and market flexibility in an integrated way. For them, volatility is not a risk to be managed — it is the medium in which they work.
The consolidation already underway is no accident. It is the logical consequence of a market that spent years shaped by subsidies and stable structures now reaching maturity. Anyone who has lived through that transition knows: the craft was never the problem. The question is what you do with it.
