TECNALIA has joined as a technology partner of the startup Surion Wind Systems to accelerate the modernization of wind farms in Europe and the United States through solutions of repowering that optimize the useful life and profitability of the facilities.
Global challenge: the urgency of wind power repowering
The alliance addresses a critical need in the international energy market: the obsolescence of large fleets of wind turbines. In key regions such as Europe and the United States, wind farms face problems of aging and power loss, compounded by regulatory and market pressure to increase the efficiency of installed capacity.
Given this scenario, partial or total renovation, technically known as repoweringIt is consolidating itself as the most advantageous option to ensure the continuity of wind power generation.
Technological contribution and axes of collaboration
The entry of TECNALIA The capital of the Alava-based startup is structured through the initiative deeptech4ImpactThe research center contributes its technical know-how in the design of power control systems, focusing its activity on three fundamental axes:
- Technology transfer: Access to proprietary developments, specialized software and industrial property for wind power control systems.
- Advanced analysis tools: Creation of instruments for load analysis, loss segregation in electrical generators and dynamic behavior modeling.
- Technical validation: Development of a functional prototype and implementation of a scale test bench to certify the system's performance.
José Luis Villate, Director of Renewable Energies and Thermal Efficiency at TECNALIA, highlights the strategic relevance of the agreement: "With this participation in Surion Wind SystemsThe innovations proposed by the startup will accelerate the repowering process for a large number of existing wind farms, helping to achieve highly profitable business models and facilitating environmental permitting."
Economic impact and efficiency of the new model
The value proposition of Surion Wind Systems It introduces a disruptive innovation in the sector: a multiple transmission system and modular structure that facilitates local manufacturing and the reindustrialization of regional suppliers.
The following are the key figures that define the efficiency of this technological solution compared to traditional methods:
| Key Indicator | Data / Impact |
|---|---|
| Infrastructure reuse | Up to 48% (existing components) |
| Cost reduction | Up to 44% in the repowering |
| Installable power | Range of 1.5 MW to 3.0 MW |
| TECNALIA Deeptech Portfolio | 16 startups (managed by TECNALIA Ventures) |
| Portfolio Value Growth (2024) | + 187 % |
| Capital attracted (2024) | 74 millones de euros |
According to Rubén Ruiz de Gordejuela, managing director at Surion Wind SystemsThe company seeks to "optimize the process of repoweringIndustrialization, optimizing the company as a whole, and maintenance, applying to Onshore the latest technologies offshore accounts«.
This move reinforces the strategy of TECNALIA Ventures, whose portfolio of investee companies experienced remarkable growth in 2024, with an 83% increase in the turnover of its companies.
Key points and frequently asked questions about the TECNALIA-Surion alliance
What is the repowering and why is it necessary?
It is the partial or total renovation of older wind farms. This is necessary because many fleets in Europe and the US are aging, losing power, and need to increase their efficiency to remain profitable.
What economic advantages does the Surion solution offer?
It allows reusing up to 48% of existing infrastructure and replacing only key components, reducing investment and maintenance costs by up to 44%.
What exactly is TECNALIA's role in this collaboration?
It acts as a technology partner, contributing industrial property, control software, load analysis tools, and a test bench to validate the prototype, accelerating the startup's entry into the market.
