Overview

First-of-its-kind grid stability

Our clutchless synchronous condenser enables an existing 7F.05 gas turbine to operate unfired in synchronous condenser mode. This allows the unit to support the grid without burning fuel or generating power, while maintaining the ability to return to power generation quickly when needed.

In synchronous condenser mode, the gas turbine remains synchronized to the grid and provides reactive power, inertia, and fault current capability. These grid services become increasingly important as the generation mix changes and inverter-based resources account for a larger share of the system.

This solution integrates synchronous condenser capability into your existing 7F.05 gas turbine, allowing the unit to support grid stability in new ways.

Benefits

More value from your 7F.05 gas turbine

During mid-day non-dispatch windows, gas turbines may sit idle while the system continues to need voltage support and stability. The clutchless upgrade creates more value during these periods by expanding grid support capabilities, reducing the need for additional infrastructure, and putting existing units to work in new ways.

Helping to deliver grid-strength services

In synchronous condenser mode, the 7F.05 provides rotating inertia and fault current capability, both critical grid-strengthening services. Rotating inertia helps support system frequency during sudden generation or load changes, while fault current capability helps ensure the performance of protection system during grid disturbances.

Switch quickly as grid demands change

This upgrade was engineered to avoid drivetrain reconfiguration, balance-of-plant (BOP), and structure changes. The unit transitions smoothly between generation and synchronous condenser mode, helping to ensure you can meet shifting grid demands with confidence.

Fully validated on 7F.05 gas turbine

7F.05 gas turbines have been validated for unfired operation in synchronous condenser mode, with stable and repeatable transitions confirmed between fired and unfired states. Testing found no aeromechanic or clearance limitations across the operating envelope and confirmed that thrust load and bearing requirements support long-term service.
