LONGi Lands RWE Solar-Storage Deal in Italy

• LONGi will supply RWE with solar PV modules and ~300MWh battery storage for a hybrid Italy project, boosting grid flexibility as renewables surge across Europe.

LONGi Green Energy Technology has agreed to supply solar photovoltaic modules and battery storage technology for a hybrid renewable project in Italy with German utility RWE. The system will combine utility-scale solar generation with an energy storage capacity of about 300 MWh.

The battery component will store excess solar power and discharge it during higher-demand periods to improve flexibility and reliability as Italy expands energy storage to support rising renewable penetration. The deal also reinforces LONGi’s growing presence in Europe and aligns with RWE’s plan to expand its portfolio of integrated solar-plus-storage assets across the region.

How will LONGi’s 300 MWh solar-plus-storage deal with RWE shape Italy’s renewables?

• Accelerates Italy’s shift from “generation-only” solar to firmed solar by pairing PV output with multi-hour storage, helping reduce curtailment when midday solar is high.
  
• Improves grid flexibility as Italy increases variable renewables, because stored energy can be dispatched during evening peaks and periods of low wind/PV, easing balancing needs for operators and utilities.
  
• Supports RWE’s strategy to scale utility-scale hybrid assets, which can influence permitting, contracting norms, and financing structures for future solar-plus-storage projects in Italy.
  
• Strengthens the domestic and European supply chain for both modules and battery systems, potentially shortening lead times for new capacity and making it easier to meet growing demand for storage-enabled renewables.
  
• Sets a reference configuration for developers and investors—300 MWh at a utility scale—showing how large systems can be sized to match Italy’s ramping and peak demand requirements.
  
• Reinforces market signals for capacity value: projects that can reliably deliver during high-price or high-demand hours tend to attract more revenue streams than PV alone.
  
• Enhances portfolio-level reliability for utilities and corporate offtakers by offering a dispatchable profile, which can be important for long-term power purchase agreements in Italy.
  
• Encourages broader adoption of energy storage across Italian renewable buildouts by demonstrating bankable hybrid performance—likely increasing interest from both grid-facing utilities and private generation developers.
• Contributes to decarbonization targets by enabling higher renewable penetration with less operational stress on the grid, supporting Italy’s transition while maintaining power quality and system stability.
