Copilot Capital Bets on Green Eagle’s 90 GW Autopilot

Copilot Capital took a majority stake in Green Eagle Solutions on September 8, 2026, buying control of software that already runs 90 GW of renewables. Terms were not disclosed. The London firm is using the last cheque in its first fund on a Madrid autopilot, not on a slide-deck promise.

ARSOS, launched in 2020, already runs over 10,000 wind turbines and fires more than 1 million automated actions a month across wind, solar, batteries and hydro. Copilot is betting that U.S. and global fleets will pay for that control room rather than keep staffing it.

Copilot Bought the Autopilot Already Running 90 GW

Green Eagle Solutions announced a majority investment from Copilot Capital as the step that is supposed to make ARSOS the global standard for renewable operations. Copilot is a lower mid-market software buyer, not a climate-tech venture shop writing a minority cheque.

Alejandro Cabrera, co-founder and chief executive, said the firm already knew the market position and had a plan for a company at this stage. Juan Fernández, co-founder, said the original brief was to take round-the-clock monitoring off operators’ plates so they could spend time on higher-value calls. Both men stay in place. The company put it as the same founding team and the same vision, with more capacity to execute.

John Messer, founder and managing partner of Copilot Capital, called Green Eagle a fit with a strategy of backing fast-growing European software businesses and turning them into category leaders abroad. That is the wager in one sentence: take a Spanish product that already sits on 90 GW and sell it as the default operating layer, starting with the United States.

ARSOS AT THE BUYOUT

• Fleet on the platform: 90 GW of wind, solar, battery storage and hydro across Iberia, Europe, North America, Latin America, Australia and other EMEA markets.
• Machines in auto: Over 10,000 wind turbines operate without a human in the loop for routine work.
• Monthly workload: More than 1 million automated actions, from fault resets to curtailments and dispatch.
• Company size: 45 customers, 66 employees and operations in 18 countries.

Those figures are the asset Copilot is underwriting. A 66-person shop running 90 GW only works if the product really does the night shift. If it does, the next constraint is sales, not code.

How ARSOS Runs Wind Farms Without a Night Shift

Cabrera and Fernández founded the company in Madrid in 2012 as software engineers who did not want to ship another monitoring screen. ARSOS sits between physical assets and the tools operators already use. It detects an anomaly, decides on a protocol the client has configured, and sends the command to the turbine, plant or substation.

The suite is five products that share that loop. Clients switch modules on at their own pace rather than ripping out SCADA.

WHAT THE SUITE ACTUALLY DOES

• O&M Robot: Fault handling, preventive stops and 24/7 monitoring; Green Eagle says it automates up to 80% of control room activities and can scale a team without adding headcount.
• Grid and Market Robot: Applies TSO curtailments, talks to Spain’s system operator, and can bid mFRR, RR and aFRR, or cut output when prices go negative.
• Asset Performance: Site and device data, a SCADA warehouse, and IEC availability and performance KPIs for portfolio managers.
• CompactSCADA: A local box that keeps protocols and telemetry running when the cloud link drops.
• Substations: Alarm handling and remote switching on medium- and high-voltage gear, from about 50 MW to 1 GW of evacuation capacity.

Green Eagle has also published a one-month pilot on two sites totalling 299 MW, inside an operator that runs about 26 GW. No new hardware went in. ARSOS used the SCADA already on site and the operator’s own reset rules, and it stood down when a work order or a curtailment was live.

ONE-MONTH PILOT ON 299 MW

That is the product Copilot is taking into a market that still puts a person in front of most of those alarms. The open question is whether U.S. control rooms will accept a Madrid protocol engine on assets that large.

The €6 Million Round That Got Them to 90 GW

Before Copilot, growth was funded by SET Ventures, Kibo Ventures and A&G Energy Transition Tech Fund. SET and Kibo were in early. A&G led a €6 million Series A round announced on December 19, 2023, with both earlier backers coming in again.

At that round ARSOS was already on over 15 GW in Spain, more than 20% of installed capacity in the country, plus more than 3 GW abroad. In 2023 it ran over 50,000 site curtailments and issued 40,000 commands to wind turbines. Juan Diego Bernal, then managing director of the A&G fund, said the technology was unique in the market and that the money was meant to push international scale, including the United States.

A&G went in at the end of 2023. On September 8, 2026 it sold that stake to Copilot, the fund’s first exit, returning more than double the capital with an annualised net return close to 40%. Alejandro Núñez, who heads the fund, treated the sale as proof that the original energy-transition thesis could pay.

This is the first divestment from the A&G Energy Transition Tech Fund and confirms the philosophy on which it was founded: to support technology companies capable of accelerating the energy transition and industrial transformation, and to actively support them until they are established and achieve international scale. Returning more than twice the capital invested with an annualised net return of close to 40 per cent demonstrates that impact and financial return are not conflicting objectives.

SET Ventures is out as well. Anton Arts, the partner who led that relationship, had pointed to a vision that was clear from the first meeting and to a team that hit or beat its targets. The venture chapter is closed. A buyout shop now owns the majority and has to turn 45 customers into a much larger book.

THE PATH TO THE BUYOUT

1. 2012: Alejandro Cabrera and Juan Fernández found Green Eagle Solutions in Madrid to automate renewable control-room work.
2. 2020: The company launches the ARSOS Automation Suite, built to execute actions rather than only flag them.
3. December 19, 2023: A&G leads the €6 million Series A with SET Ventures and Kibo Ventures; ARSOS is already past 15 GW in Spain.
4. September 8, 2026: Copilot Capital takes majority control. A&G records its first exit. Green Eagle reports 90 GW, 45 customers and 66 staff.

The missing number is the price Copilot paid. Without it, the 40% net return is A&G’s result, not a public valuation of Green Eagle. What is public is the change in owner: venture capital that financed product and early markets has handed the company to a fund whose job is go-to-market, hiring and cross-border sales.

Copilot’s Last Check From a $200 Million Fund

The Friedkin Group International seeded Copilot Capital as a $200 million vehicle for European software firms that have outgrown venture but are still too small for classic buyout funds. Copilot looks for businesses generating €5 million to €15 million in recurring revenue and talks about helping them toward about €50 million. Messer has said Europe has some 60,000 SaaS companies, many of them ignored by both venture and large private equity.

Green Eagle is the fifth and final investment from that first fund. The earlier majority holdings are Relesys, SecureFlag, PriceShape and Zendr, a set that already spanned the Nordics, the United Kingdom and Spain. Squire Patton Boggs advised Copilot on this deal, the fifth Copilot mandate for that firm. Copilot’s own pitch to founders is that they remain the pilot. Messer came from Tenzing, where he led a 9.6x return on CitNOW, and the fund’s written line is internationalisation, professional sales and data and AI, not founder replacement.

That mandate is why this deal is a bet rather than a science-project grant. Copilot does not need ARSOS to invent a new category. It needs a 66-person company that already touches 90 GW to hire a sales engine that can repeat the two U.S. logos it already has. If Green Eagle is inside the €5 million to €15 million band the fund was built for, the next jump is organisational. The company has not published revenue.

Two of America’s Largest Power Producers Signed On

The U.S. plan is not a cold start. Green Eagle says it already works with two of the country’s largest power producers, and that Copilot’s money is meant to speed a dedicated U.S. go-to-market while Europe keeps growing. The producers are unnamed, so the claim has to be read as a beachhead, not a map of the fleet.

They already understood our business, where we sat in the market, and had a real strategy for a company at exactly our stage.

Alejandro Cabrera, Co-Founder and CEO, Green Eagle Solutions

Copilot’s second stated use of proceeds is more data and AI on the same detect-decide-do loop, still with no manual step required for the work ARSOS already takes. Fernández said the new capital is for new markets, starting with the United States, without pulling back in Europe. For a fund that lists internationalisation as a core play, two domestic majors are the reference accounts a new U.S. sales lead would want on the first slide.

The harder part is labour and liability. A U.S. independent power producer that puts fault resets and curtailments on a European SaaS stack is moving the night shift out of its own remote operations centre. ARSOS is designed to work with existing SCADA and to freeze automation when a work order is open, which is how Green Eagle argues it does not fight the on-site technician. Whether that argument clears U.S. grid, union and insurance desks is the execution risk Copilot just bought.

The IEA Sees 4,600 GW of New Renewables by 2030

Green Eagle pointed to the International Energy Agency when it explained why the raise is happening now. In Renewables 2025, the agency says global renewable power capacity will more than double by 2030, an increase of 4,600 GW of new renewable capacity, roughly equal to adding the installed power systems of China, the European Union and Japan. Solar PV is expected to supply about 80% of that increase. The same outlook flags grid integration as a live constraint, which is exactly the work ARSOS’s grid module is built to execute: curtailment, telemetry, voltage and market instructions, without waiting for a human to click.

That forecast is about building plants. Copilot’s product is about running them. Even if U.S. policy slows some new wind and solar, the turbines and inverters already connected still throw faults, still take TSO orders, and still lose money when a reset sits in a queue for half an hour. The 299 MW pilot’s jump from about 30 minutes to under 1 second is the commercial case in miniature. Multiply that logic across 90 GW, then across whoever among the next 4,600 GW will not hire control-room staff in a straight line with megawatts.

Portfolios are also getting messier on purpose: wind plus solar plus batteries plus hydro, merchant prices, and thicker regulation as renewables take more of the mix. ARSOS was written for that pile, which is why a generalist software fund, not an infrastructure yield vehicle, is the buyer. Copilot can only win if operators accept that a lot of what a 24-hour desk does is protocol, not judgement.

Founders Keep the Helm After the Buyout

Cabrera remains chief executive. Fernández remains in the founding seat he has held since 2012. Copilot’s public description of the work ahead is a U.S. sales build, a stronger operating backbone, and more investment in the data and AI that already sit under ARSOS. Customers were told the product path does not change, only the speed.

The wager is now on a sales calendar, not a prototype. Two large U.S. producers are on the platform, 90 GW is already live, and the last Fund I cheque is in. If those accounts turn into a repeatable American motion, Copilot will have bought an autopilot that was already flying. If they stay logos on a slide, the majority stake is just an expensive European control-room tool with a New York to-do list.
