AEP nears permit okay for five ‘black start’ generators at Lawrenceburg plant

The Indiana Department of Environmental Management is taking comment until May 21 on a draft air permit approval for AEP Generating Co. to install five black start generators at the gas-fired Lawrenceburg Plant in Lawrenceburg, Indiana.

The department’s Office of Air Quality (OAQ) has reviewed a modification application, submitted by AEP Generating on Feb. 23, relating to the construction and operation of five  emergency black start generators. The five would each have a maximum capacity of 3,717 horsepower, using no controls, and exhausting outdoors. Black start engine means an engine whose only purpose is to start up a combustion turbine.

The plant currently is made up of four natural gas-fired combustion turbines, identified as units CT1, CT2, CT3, and CT4, which commenced construction in 2001, each with a nominal heat input capacity of 1,906.4 MMBtu/hr (higher heating value)/ The combined nominal power output is 1,130 MW. The plant also has four heat recovery steam generators, identified as units HRSG1, HRSG2, HRSG3, and HRSG4, which commenced construction in 2001, equipped with natural gas-fired duct burners, each with a maximum heat input capacity of 310 MMBtu/hr (higher heating value).
