• 162 MW Belinchón solar cluster delivered in under 14 months, avoiding over 42,700 tons of CO2 annually
  • Multi-buyer PPA links renewable supply directly to pharmaceutical scope 2 and 3 emissions reduction
  • Project highlights Spain’s role as a key hub for industrial decarbonisation and clean energy investment

Zelestra has brought three solar plants online in Castilla-La Mancha, adding 162 MW of renewable capacity to Spain’s grid while directly supporting decarbonisation efforts across the pharmaceutical sector.

The Belinchón I, II and III projects were delivered in under 14 months by Zelestra’s in-house engineering, procurement and construction team, a timeline that reflects growing pressure on developers to accelerate clean energy deployment in Europe. Around 400 jobs were supported during construction, underscoring the local economic impact tied to renewable expansion.

The cluster comprises 275,000 solar modules installed on single-axis trackers to maximise generation efficiency. Now operational, the projects are expected to avoid more than 42,700 tons of CO2 emissions annually, contributing to Spain’s broader climate targets and the EU’s decarbonisation trajectory.

Corporate Demand Drives New PPA Structures

The projects are underpinned by a long-term, multi-buyer power purchase agreement structured through the Energize programme, a supply chain decarbonisation initiative managed by Schneider Electric. The model reflects a shift in corporate procurement, where multiple buyers aggregate demand to secure renewable energy at scale.

Energize brings together major pharmaceutical companies including Takeda Pharmaceuticals International AG, Teva Pharmaceutical Industries and UCB, alongside suppliers such as Avantor, Organon LLC, Perrigo and West Pharmaceutical Services Inc. The structure is designed to address both scope 2 emissions from purchased electricity and scope 3 emissions embedded across supply chains.

By linking renewable generation directly to pharmaceutical manufacturing and supplier networks, the agreement provides a replicable framework for hard-to-abate sectors seeking to align with science-based climate targets.

Industrial Decarbonisation Moves Into Supply Chains

Luis Alvargonzalez, Zelestra’s Country Manager in Spain, said: “The Belinchón cluster is a significant new addition to our global portfolio of operational projects and it’s also a major project supporting Spain’s clean energy transition. It is a strong example of how we deliver projects quickly and efficiently. It also demonstrates how we are supporting industrial decarbonisation, and I am proud of the positive impact Belinchón will deliver for the pharmaceutical sector across Spain and wider in Europe.”

The project illustrates how renewable developers are moving beyond traditional utility-scale supply to integrate directly with industrial value chains. For pharmaceutical companies, where emissions often sit outside direct operations, access to aggregated renewable energy solutions is becoming a critical lever for meeting climate commitments.

Spain Emerges as Strategic Renewable Hub

Castilla-La Mancha has become a focal point for Zelestra’s Spanish operations, with 470 MW across nine contracted projects and a broader development pipeline exceeding 360 MW across solar, wind and battery storage. Nationally, the company reports 1.1 GW of contracted clean energy projects and a development pipeline surpassing 7 GW.

Spain’s combination of strong solar resources, supportive regulatory frameworks and corporate demand for clean power continues to attract investment. The country is increasingly positioned as a gateway for pan-European decarbonisation, particularly for energy-intensive industries and multinational supply chains.

Globally, Zelestra’s EPC division has delivered approximately 3.5 GW of projects, supported by a team of more than 300 specialists. The scale reflects intensifying competition among developers to deliver integrated, multi-technology solutions that meet both grid needs and corporate sustainability requirements.

What Executives Should Watch

For C-suite leaders and investors, the Belinchón cluster highlights a convergence of policy, finance and corporate climate strategy. Multi-buyer PPAs are emerging as a key instrument to unlock renewable capacity while distributing risk across participants. At the same time, supply chain decarbonisation is shifting from ambition to execution, with measurable emissions reductions tied to energy procurement.

As Europe accelerates its clean energy transition, projects like Belinchón point to a broader trend. Renewable infrastructure is no longer only about grid decarbonisation. It is becoming a central tool for industries to manage regulatory risk, meet investor expectations and secure long-term energy price stability.

The implications extend beyond Spain. Aggregated procurement models and cross-sector partnerships are likely to shape the next phase of global decarbonisation, particularly in sectors where emissions are deeply embedded across complex supply chains.
