Florida BESS Portfolio
100MW / 200MWh

​The Challenge: Balancing Reliability, Cost, and Sustainability

Florida’s growing demand for electricity and the state’s clean energy goals have created a need for flexible, dispatchable storage solutions that complement renewable resources while ensuring reliability. Traditional peaking plants are expensive to operate, carbon-intensive, and less responsive to modern grid requirements.

​

The Florida BESS Portfolio addresses these challenges by:

​

• Delivering peaking capacity without new fossil-fueled peakers.

• Enhancing operational flexibility for renewable integration.

• Provide resiliency benefits during outages and extreme weather events.

• Reducing fuel costs while supporting the utility’s long-term net-zero carbon emissions target by 2050.

​

​Doosan GridTech's Solution

Doosan GridTech was selected to design, procure, and integrate a turnkey lithium-ion BESS portfolio across several Florida sites.

​

Each site is managed by the Doosan GridTech Intelligent Controller® (DG-IC®), a vendor-agnostic, open-standard platform that enables precise dispatch, grid support, and compliance with operational standards. The systems can respond in real time to grid events through the DG-IC, optimize storage utilization, and support renewable integration.

 

Core Solution Elements

• Open-standard integration with existing grid infrastructure.

• Real-time adaptability to dynamic operating conditions and market signals.

• High-fidelity hardware-in-the-loop (HIL) simulation to validate performance before deployment.

• Containerized, liquid-cooled lithium-ion batteries for efficiency and durability in Florida’s climate.

• Advanced power conversion system (PCS) for efficient, reliable performance.​

 

By shifting stored energy to meet peak demand, the portfolio will provide peaking capacity, fuel savings, and operational flexibility, reducing reliance on fossil-based generation while enhancing grid reliability.

​

Outcomes and Impact

When operational in 2025, the Florida BESS Portfolio will deliver far-reaching benefits at both the utility and community level:

​

• Grid Reliability: Provides instantaneous response to grid events, stabilizes voltage and frequency, and delivers backup during outages, which is critical in hurricane-prone regions.

• Cost Savings: Cuts dependence on expensive peaker plants and optimizes fuel use, resulting in lower operating costs that can ultimately benefit ratepayers.

• Operational Flexibility: Allows the utility to shift energy in real-time, support renewable dispatch, and balance demand during Florida’s extreme weather-driven load fluctuations.

• Sustainability: A major step toward net-zero carbon by 2050, reducing reliance on fossil fuel plants and supporting statewide clean energy mandates.

• Future-Ready Platform: Designed for scalability and augmentation, the portfolio can be expanded as demand grows or new technologies become available.

• Community Benefits: Improves reliability for nearly a million customers and sets the stage for broader renewable adoption across Florida.​

​

​Why This Project Matters

The Florida BESS Portfolio is among the state’s most ambitious energy storage initiatives and serves as a blueprint for utilities nationwide. It underscores how large-scale storage can:

​

• Increase reliability and resilience in extreme weather conditions.

• Lower costs while cutting carbon emissions.

• Enable a cleaner, more resilient grid for future generations.

 

By partnering with Doosan GridTech, the utility is deploying one of Florida’s most significant distributed storage portfolios, demonstrating how vendor-agnostic integration, intelligent controls, and turnkey delivery can accelerate the clean energy transition.
