    Green Eagle Solutions, 10 years making wind energy easier

    September 29, 2022 - CE Noticias Financieras


      Green Eagle Solutions was founded by Alejandro Cabrera (see interview) and Juan Fernández Riejos in 2012. It was born with the aim of improving the operation of wind farms, and after ten years in the sector, the company has managed to implement a new disruptive way of operating wind farms. With the exponential growth of installed power in Europe, and the urgent need to integrate more and more energy from renewable resources into the grid, the complexity of operational scenarios has skyrocketed in recent years. From regulatory changes by the system operator (Red Eléctrica-REE, in the case of Spain) to make the system more robust and reliable, to the monitoring and control of technologies with different systems and ages. All this results in an operation that has to be more individualized and, therefore, requires more dedication and resources from the control centers.

      But Green Eagle Solutions does not only live from wind energy. They also work with photovoltaics, with which they have experienced significant growth, especially in electricity market participation systems and compliance with new legislation. And for which they have developed a specific technology for delegated offices in a cloud environment.

      We asked Alejandro Cabrera, CEO of the company, about the complexity of both technologies. "Without a doubt, wind is the more complex technology. We work continuously with owners and operators to identify operational processes that can be automated and therefore improved. To date, we have managed to increase wind farm production by 1% thanks to process automation, without the need to renew any hardware," he says.

      ARSOS robot

      The ARSOS robot has played an important role in these improvements. After the first years developing tools and software solutions to make remote operations more efficient and, above all, scalable, in 2015 the first ARSOS robot was implemented. A system based on robotic automation of processes that, thanks to its algorithms, is capable of operating hundreds of turbines at a time, responding autonomously and in a matter of seconds to alarms and events that they manage from the control centers. "With this system, operators do not need to actively monitor all the turbine events, but focus their attention on those actions on which the robot cannot act and which, therefore, require the attention of human intelligence," Cabrera explains.

      Once the action protocols have been automated, the focus is now on the artificial intelligence of these software robots. "We are currently in the process of analyzing the performance of ARSOS to ensure that the software robot not only follows a programmed logic process but, thanks to the application of machine learning tools, can in the future recommend improvements to the customer's operating protocol, thus minimizing wind turbine downtime and increasing the availability of the wind turbines," he says.

      ARSOS is not only intended to improve the management capabilities of early wind farm control systems, which have older machines. "Our tool was conceived and developed to be used by the operators of any renewable energy control center. It is designed for the managers of these centers to improve their kpis (Key Performance Indicators), response times, safety, and to assist in the standardization of asset operation. The greater the volume of assets being operated, the more value we can bring," says the CEO of Green Eagle Solutions. He also points out: "The use of ARSOS Robot does not imply replacing control systems; it is developed to coexist with existing systems. It is also true that we offer a control center service for those owners or O&M providers who do not have their own control center or simply prefer to delegate the operation to us. In our control center we also use the ARSOS Robot tool".

      The use of ARSOS Robot does not imply replacing control systems because it is developed to cohabit with existing systems.

      As for the latest generation of wind turbines, "ARSOS continues to add a lot of value by helping operators with monitoring and sending intelligent notifications to the parties involved. In any case, what is considered modern today ceases to be so the instant the government or regulation changes on the part of the electricity system operator (REE). "With our software we can give a quick response without the need to change the OEM (Original Equipment Manufacturer) software. As a recent case we have the implementation of the 3.11 procedure or SRAP (System of Automatic Power Reduction) that implies a power reduction to 0 in only 5 seconds. Not all plants allow this operation, not even the modern ones, and we implemented it with ARSOS".

      RWE control center, a success story

      One of Green Eagle Solutions' most relevant success stories in the automation of remote operations was recently implemented for the RWE Iberia control center. The company would be in charge of remote operations not only for the Spanish portfolio but also for all wind farms located in Italy. The increase in megawatts to be operated is a fact that operators are facing, a very positive fact for the industry and the wind business fabric.

      However, new processes and tools are needed to adjust to this growth. The expansion of renewable assets meant for RWE Iberia an increase in the number of actions required per operator, in addition to working with different technologies that they were not used to before. Therefore, they decided to automate mainly turbine start-up and shutdown actions, notifications to plant operators and SET points, thus reducing their response time from 15 minutes to a matter of seconds per event or alarm.

      First round of investment

      Green Eagle Solutions has not stopped for a moment to evolve its technology. But from a business point of view, until very recently, the company had organic growth because it did not have sufficient resources to open up to new challenges and markets. Things started to change last year, when it raised its first round of investment led by SET Ventures, a Dutch fund specializing in the renewables sector, which was then followed by Kibo Ventures, a Spanish technology fund.

      Today, the company's board of directors is made up of the two founders, Juan Fernández and Alejandro Cabrera; Anton Arts, managing director of SET Ventures; Juan López, investment director of Kibo Ventures; and Lars Hoffman, chairman of the board. "In this coming 2023 -says Alejandro Cabrera-, we expect to carry out the second round of investment to continue growing and expanding Green Eagle Solutions outside Europe, in a much more effective and diligent way".
