Hybridized Gas Turbine (GT) Plus Battery Energy Storage Systems (BESS) Technology Assessment and Application 

As the grid needs continue to evolve with increasing regulatorymandates for reducing CO2 emissions and greater variable renewableenergy penetration, generators are being required to provideflexible operations while reducing the impact on emissions, O&M,and availability. To meet these needs, power producers are evaluatinghybrid gas turbine plus battery energy storage plants. Hybridizinggas turbine plants by adding battery energy storage combines thebattery’s flexibility and responsiveness with the gas turbine’s abilityto provide sustained energy.Hybrid gas turbines and energy storage offers distinct operationalcharacteristics, including:

- Lower plant costs­­> lower cost to provide services ­­> lower costto rate payers

- Optimized GT operation (lower fuel usage) ­­> lower GHG and emis­sons

- Improved grid stability for isolated/islanded systems

- Black start with reduced emissions

•Increased grid resiliency, the ability to respond to events that candisrupt supply on a system-wide basis, and

- An answer to the growing utility challenge - plenty of capacity,but not the right kind of capacity

This paper seeks to inform the technical community and decision making on hybridized gas turbine plus energy storage system development providing an overview of hybrid system characteristics,the value proposition, and the barriers to fully realizingthose benefits. With this perspective, the very large fleet of existinggas turbines worldwide can be better utilized (re-purposed) for theevolving grid changes needed to adapt to growing renewable capacityand reduced GHG emission targets.
