GE Achieves Battery-Enabled Blackstart of Heavy Duty Gas Turbine

General Electric (GE) has for the first time achieved blackstart of a GE heavy-duty gas turbine using battery energy storage.
The company announced on Feb. 26 it completed black start of a GE 7F.03 gas turbine at a 150-MW simple-cycle unit at Entergy Louisiana’s Perryville Power Station using a 7.4-MW battery-based energy storage system. The unit in Ouachita, Louisiana, began operation in 2001.
GE told POWER on March 5 that the project uses lithium-manganese-cobalt-oxide (or NMC) batteries, and it produces 7.4 MWh (DC) as embedded energy and 6.6 MWh (AC) as usable energy at the point of installation. According to a GE project leader, the battery energy storage system enables blackstart by creating a voltage reference—also known as “grid forming”—to which the turbine and its associated auxiliary power systems can synchronize. These components “then draw the required current to rotate the turbine and begin the start-up process.”…
