Bankable Energy Storage for Large-Scale Solar, CRESS, LSS and Grid-Connected Projects
Solunar supports developers, EPCCs, infrastructure funds, utilities and asset owners with integrated Utility-Scale Energy Storage System solutions for large renewable energy and grid-connected projects.
The market opportunity
Malaysia's renewable energy sector is entering a new phase. As large-scale solar, CRESS, data-centre power demand and grid-connected renewable projects grow, energy storage is becoming a critical part of the power infrastructure ecosystem.
Solar alone is no longer enough. The market now needs solutions that manage intermittency, improve grid stability, support dispatchability and strengthen renewable project economics — which is where utility-scale ESS becomes essential.
Challenges at utility scale
Large-scale renewable developers face a recurring set of challenges:
- Solar generation is intermittent
- Grid connection capacity can be limited
- Energy output may not match demand timing
- Bankability depends on reliable long-term performance
- Investors and banks need proven technology and clear risk management
- O&M complexity increases when storage is added to solar farms
- Improper integration can cause performance, safety and warranty issues
The Solunar solution
Solunar provides complete utility-scale ESS farm solutions for large energy infrastructure projects. For utility-scale projects, BESS is not just a battery purchase — it is a full infrastructure system that must be properly designed, integrated, operated and maintained.
