Verano Energy Taps Sungrow for Landmark 152MW Observatorio Storage Project in Chile

In a significant move to bolster Chile’s rapidly evolving renewable energy landscape, developer Verano Energy has officially tapped global clean energy powerhouse Sungrow to supply a massive 152MW/606MWh battery energy storage system (BESS) for its flagship Observatorio project. This collaboration represents a pivotal step in integrating large-scale solar power with high-capacity storage, signaling a broader trend toward grid stability and the mitigation of renewable energy curtailment in the Latin American region.

Main Facts: A Technical Overview of the Observatorio Project

The Observatorio project stands as a hybrid infrastructure marvel, designed to bridge the gap between intermittent solar generation and consistent energy delivery. At its core, the facility will feature a 135MW solar photovoltaic (PV) array, underpinned by high-efficiency Sungrow SG350HX-20 inverters.

The heart of the project, however, is the state-of-the-art energy storage component. By deploying Sungrow’s proprietary PowerTitan 2.0 ESS solution, the facility is engineered for a four-hour discharge duration. This 606MWh capacity is designed to store excess solar energy produced during peak daylight hours, effectively shifting that power into the evening or high-demand periods. This operational flexibility is critical for a grid that is increasingly reliant on variable renewable energy (VRE) sources like solar and wind.

Beyond the hardware, the agreement includes a comprehensive 25-year long-term service agreement. This maintenance contract ensures that the BESS maintains optimal performance metrics over its operational life, securing the facility’s role as a long-term asset for the Chilean national grid.

Chronology: The Path to Observatorio

The announcement comes on the heels of a series of strategic global expansions for Sungrow. While the Observatorio project marks a major milestone in Chile, it follows a successful international track record for the company.

• Mid-2026 Strategic Pivot: Throughout the first half of 2026, both Verano Energy and Sungrow signaled an intent to focus heavily on "firming" renewable energy—the process of using storage to make intermittent generation as reliable as traditional base-load power.
• International Precedent: In June 2026, Sungrow made headlines by commissioning a massive 150MW/600MWh BESS in Nova Zagora, Bulgaria, in partnership with Sunotec. The successful execution of that project served as a technical proof-of-concept, reinforcing confidence in the PowerTitan 2.0 architecture and paving the way for the deployment in Chile.
• Contract Finalization: Following rigorous technical evaluations and supply chain assessments, Verano Energy selected Sungrow to be the primary technology partner for the Observatorio site, prioritizing the company’s ability to provide both the hardware and the quarter-century of technical support required for the project’s longevity.

Supporting Data: Why Storage is the "Missing Link"

The necessity of the Observatorio project is grounded in the current challenges facing the Chilean power sector. As the nation has aggressively added solar capacity, it has simultaneously faced the "duck curve" phenomenon—where solar generation peaks when demand is low, leading to power price drops and, frequently, the necessity of curtailment (where operators are forced to turn off renewable plants because the grid cannot absorb the excess energy).

Technical Performance Metrics

• Storage Duration: 4 Hours (606MWh / 152MW)
• Solar Capacity: 135MW
• Inverter Technology: Sungrow SG350HX-20
• Maintenance Horizon: 25 Years

By integrating 606MWh of storage, Verano Energy is effectively "clipping the peaks" of solar production and "filling the valleys" of evening demand. This optimization is not merely about storage; it is about revenue maximization and grid reliability. According to market analysts, projects like Observatorio reduce the risk of asset stranding and ensure that renewable energy producers can fulfill their obligations to the grid even when the sun is not shining.

Official Responses: Aligning Visions for the Energy Transition

The partnership between Verano Energy and Sungrow is characterized by a shared commitment to the decarbonization of the Chilean economy.

Gonzalo Feito, Sungrow LATAM regional director, commented on the significance of the deal:

"We are proud that Verano Energy has entrusted Sungrow with the supply of the energy storage solution for the Observatorio project. This agreement reinforces our commitment to developing high-performance energy infrastructure and accelerating the energy transition in Chile. Providing the PowerTitan 2.0 system is not just about the hardware; it is about providing the reliability needed to make renewable energy the cornerstone of the national power system."

Tomás Anuch, Chief Operating Officer at Verano Energy, emphasized the strategic importance for his company:

"Observatorio represents another step in strengthening Verano Energy’s position as a key player in renewable energy generation across the region. The integration of storage allows us to unlock the full potential of our solar resource, provide greater flexibility to the power system and deliver solutions that meet the needs of a market increasingly focused on renewable energy integration. Having a technology partner such as Sungrow also gives us the confidence to develop a project that meets the highest standards of performance and reliability."

Implications: Reshaping the Chilean Grid

The implementation of the Observatorio project carries significant weight for the broader Latin American energy sector.

1. Grid Stability and Ancillary Services

Beyond simple energy shifting, the BESS provides "ancillary services." These include frequency regulation and voltage support—critical functions that were historically performed by spinning reserves in fossil-fuel-powered plants. By providing these services through a BESS, the Observatorio project effectively replaces the role of conventional thermal plants, proving that renewables can provide a stable, "grid-forming" service.

2. Market Competitiveness

For Verano Energy, this project serves as a model for future utility-scale developments. By standardizing the integration of BESS into their solar assets, the company is insulating itself from the volatility of spot-market electricity prices. This makes the company more attractive to investors who are increasingly wary of projects without storage capabilities in high-penetration solar markets.

3. The Future of the Energy Transition

Chile has set ambitious climate goals, aiming for a carbon-neutral power sector by 2050. To reach this, the country must solve the geographic and temporal mismatch between its solar-rich northern regions and its industrial demand centers. Large-scale battery storage is the most viable technological solution to this challenge.

The successful deployment of the PowerTitan 2.0 system at Observatorio will likely serve as a benchmark for future regulatory policy in Chile. Regulators are closely watching how these large-scale storage systems perform, as their success provides the empirical data necessary to create market frameworks that incentivize further investment in energy storage.

Conclusion: A New Era of Reliability

The collaboration between Verano Energy and Sungrow marks a turning point in the maturation of Chile’s renewable energy sector. By moving beyond simple generation and embracing storage as a fundamental component of the project lifecycle, Verano Energy is setting a new standard for reliability and efficiency.

As the global energy transition accelerates, the Observatorio project stands as a testament to the fact that the future of electricity is not just in how much renewable energy we generate, but in how effectively we manage, store, and distribute it. With a 25-year commitment to performance and the deployment of cutting-edge technology, the project is well-positioned to contribute to a cleaner, more resilient, and more flexible Chilean electricity grid for decades to come.
