PPL permits gas firing at big Brunner Island coal plant

The Pennsylvania Department of Environmental Protection said in a notice in the Sept. 27 Pennsylvania Bulletin that it plans to issue an air permit change allowing gas firing at PPL Corp.’s Brunner Island coal-fired plant, according to GenerationHub.

The permit approval, to be issued to PPL Brunner Island LLC, allows “for the addition of natural gas as a fuel firing option for the three existing utility boilers (Source IDs 031A, 032 and 033A) and their associated coal mill heaters that will involve the tying in of a natural gas pipeline (Source ID 301), as well as the construction of two natural gas-fired pipeline heaters (Source ID 050) at the Brunner Island Steam Electric Station in East Manchester Township, York County,” said the brief notice. “The maximum expected increases in facility emissions as a result of the changes proposed are: 39.90 TPY VOC, 22.57 TPY CO, and 0.01 TPY lead.”

The 1,437 MW Brunner Island plant is one of the facilities that PPL plans to contribute to a new company, Talen Energy. PPL and Riverstone Holdings LLC announced in June a definitive agreement to combine their merchant power generation businesses into Talen Energy, a new stand-alone, publicly listed company.

PPL spokesman George Lewis said in a Sept. 29 e-mail to Generation Hub that PPL is still very early in the process of exploring gas co-firing as an option for the Brunner Island plant. “It’s important to note that a decision has not been made on whether to go ahead with the project,” he added. “Pursuing a modification to the plant’s air permit is one of the steps PPL is taking to keep the gas co-firing option open.”
