Zelestra and SJVN Partner for 500MW Hybrid Renewable Energy Project

March 21, 2025

In a remarkable step toward advancing renewable energy infrastructure, Spain’s Zelestra has formed a strategic alliance with India’s public sector corporation SJVN to develop a large-scale hybrid power project. This groundbreaking initiative will see the construction of a 500MW wind-solar-battery storage hybrid power plant in Solapur, Maharashtra. Combining approximately 250MWdc of solar PV, 180MW of wind, and a 90MWh battery energy storage system (BESS), the project is aimed at achieving commercial operation within the next two years. Zelestra will handle the development, construction, ownership, and operation of this ambitious venture.

SJVN’s Expanding Energy Portfolio

Transition from Hydroelectric to Diverse Renewable Energy Projects

Traditionally focused on hydroelectric projects, SJVN has diversified its portfolio to include wind, solar PV, and transmission projects. Recognized as a Navratna enterprise, SJVN boasts significant operational autonomy and can invest up to IR1 billion without requiring central government approval. This flexibility enables the company to rapidly adapt to the shifting dynamics of energy production and seize new opportunities in the burgeoning renewable energy sector.

SJVN’s FDRE tenders are a testament to this adaptive strategy. These tenders aim to integrate renewable sources into the power grid, particularly during times when solar and wind generation are low, such as early mornings and evening peaks. By facilitating the use of renewable energy even during critical demand periods, these tenders ensure a consistent and reliable supply of clean energy. The company’s involvement in such innovative projects underscores its commitment to overcoming the traditional limitations of renewable energy resources.

Collaboration with Other Industry Leaders

SJVN’s reach in the renewable energy sector is further highlighted by its collaborations with other leading entities such as Tata Power Renewable Energy and Juniper Green Energy. Tata Power recently secured a 460MW wind-solar-storage hybrid project through one of SJVN’s FDRE tenders, while Juniper Green Energy, backed by Envision Energy, initiated a project featuring a 320MWh BESS.

Zelestra’s successful bid for the 500MW hybrid project marks its first and most significant multi-technology win in India, reflecting a strategic evolution from purely renewable projects to more integrated green power solutions. This move aligns with the needs of growing industrial consumers and data centers, underscoring the company’s role in pioneering innovative solutions to meet the increasing demand for clean energy.

Zelestra’s Innovative Approach

Multifaceted Renewable Energy Solutions

The 500MW hybrid project serves as a broader indicator of the evolving landscape of renewable energy, where diverse generation and storage technologies are combined to ensure round-the-clock energy supply. Zelestra’s involvement in such an initiative signifies an industry-wide shift toward more sophisticated and integrated energy solutions. These developments are specifically designed to meet the rising demands of industrial consumers and data centers, ensuring that energy supply keeps pace with consumption patterns.

In addition to its project in India, Zelestra recently entered into a Power Purchase Agreement (PPA) in Chile. This deal involves a renewable energy project that includes 220MW of solar PV and a 1GWh battery storage system. This endeavor not only reinforces Zelestra’s commitment to expanding its global renewable energy footprint but also highlights the company’s innovative capabilities in integrating varied energy technologies to provide efficient and reliable energy solutions.

Global Footprint and Future Prospects

Zelestra’s pioneering projects exemplify its strategic global expansion and emphasis on adopting a multifaceted approach to renewable energy. By engaging in large-scale, technologically integrated projects across different geographies, Zelestra is demonstrating its ability to tailor energy solutions that address both regional and global energy challenges. This hybrid project in Solapur stands as a testament to the company’s dedication to enhancing energy security and sustainability on an international scale.

Future of Integrated Renewable Energy

Promising Developments and Sectoral Trends

The collaboration between Zelestra and SJVN represents a significant milestone in the quest for sustainable energy solutions. By integrating multiple renewable energy technologies into a single hybrid system, this project serves as a model for future developments aiming to deliver consistent and reliable energy. The broader trend suggests that such integrated projects may become increasingly prevalent as industries and governments alike strive to meet growing energy demands sustainably.

As the renewable energy landscape continues to evolve, innovative technologies and strategic partnerships will be critical in driving the sector forward. Efforts like the Solapur project not only pave the way for more resilient energy infrastructure but also highlight the role of public-private collaborations in accelerating the adoption of clean energy.

Emerging Importance of Hybrid Models

In a significant move to boost renewable energy infrastructure, Spain’s Zelestra has teamed up with India’s public sector company, SJVN, to develop a major hybrid power project. This pioneering effort will result in the construction of a 500MW hybrid power plant in Solapur, Maharashtra, combining solar, wind, and battery storage technologies. Specifically, the project will feature approximately 250MWdc of solar PV, 180MW of wind power, and a 90MWh battery energy storage system (BESS). The goal is to achieve commercial operation within the next two years. Zelestra will be responsible for the development, construction, ownership, and day-to-day operation of this ambitious project, which aims to integrate various renewable energy sources to enhance efficiency and reliability. This strategic alliance between Zelestra and SJVN marks a pivotal moment for the renewable energy sector, showcasing innovative solutions and international collaboration to meet future energy demands.
