Introducing LM6000 Hybrid EGT™Leveraging higher asset revenue with reduced costs

10MW GE Packaged ES System

LM6000 Gas Turbine Package LM6000 Hybrid EGT™• A fast-acting GE Energy Storage System coupled with a Controls Upgrade to

enable LM6000 Gas Turbines to deliver 50 MW of contingency (spinning) reserve power.

How does it work?• 10MW / 4.3MWh Li Power Battery• GE Brilliance 1.25 MVA Inverters• LM6000 Hybrid Upgrade Kit• Mark VIe OpFlex™ Controls Upgrade

The Battery offers on-demand power for contingency (spinning) reserve. The OpFlex™ Fast Start starts the LM6000 to 50MW : the battery helps meet system contingency requirements.


Hybrid Grid benefits to grid stability

▪ Frequency outside the acceptable range creates grid instabilityand potential black-out

▪ Battery storage absorbs or supplies immediately power from/to the grid depending on frequency variation.

Frequency Regulation

▪ Distributed solar generation impacts locally voltage level with potential overvoltage issues and unexpected load shedding

▪ Power electronic deployed with storage can regulate grid voltage locally by controlling reactive power from/to the grid.

Voltage Support

▪ Power failures are particularly critical at industries and sites where the environment and public safety are at risk, generating additional costs.

▪ Battery storage can provide black start or grid islanding to restart load and local generation for reliable grid forming.

Grid Restoration

Battery = Fast & efficient grid service provider to leverage multiple revenue stream
