Renewable Energy for a Better Future
Flexen was born as the international platform of Eoliasur for renewable energy projects. We are already one of the main developers in the transition to a greener future.



Ready-to-Build Projects
We provide clean and efficient energy solutions through on-site (behind-the-meter) and off-site (PPAs) contracts. Whether it's wind, solar or green hydrogen, our solutions adapt to your energy and sustainability goals.

Boost the value of your land
Turn your land into a renewable energy engine. We evaluate its feasibility and accompany you at every stage to transform it into a strategic asset that generates sustainable value, promoting both economic growth and energy transition.

Sustainable Data Centers
We integrate data centers into our renewable energy projects. With wind and solar energy as a base, we guarantee a reliable, efficient and 100% renewable supply, adapted to the demands of the Artificial Intelligence and Cloud Computing industries.

Steps to develop a Renwable Energy Project
Site Identification & Evaluation
We evaluate the land’s potential and local conditions to determine its suitability for renewable energy development.
Project Design and Permits
We develop the project layout, manage environmental permits, and ensure full compliance with regulations to guarantee a successful development.
Grid and Energy Contracts
We structure Power Purchase Agreements (PPAs) and secure grid interconnection, optimizing supply with 100% renewable sources.
Ready-to-Build Delivery
We deliver a fully permitted, construction-ready project—maximizing efficiency and minimizing risk for our clients.
Expanding the Energy Frontier
From Latin America to the United States and Europe, our footprint continues to grow. In Texas, we’re developing over 3 GW of renewable and energy storage projects to meet rising demand with innovation, scale, and impact.

International presence
At Eolia Sur, our experience transcends borders. With projects developed in Latin America, the United States and Europe, we bring renewable energy solutions to strategic markets, driving a global impact in the transition to a sustainable future.
