AES plans to permanently retire two coal units on Sept. 21

A unit of AES Corp. (NYSE: AES) filed Sept 18 notices at the New York Public Service Commission about plans to retire as of Sept. 21 the coal-fired Westover Unit 8 and Greenidge Unit 4.

AEE2 LLC, a wholly owned subsidiary of AES Eastern Energy LP, is the owner of, and AES Westover LLC, a wholly owned subsidiary of AEE2, is the operator of the Westover Unit 8 located in the town of Union in Broome County. In September 2010, AEE2 served notice to the commission, the New York Independent System Operator (NYISO) and local utility New York State Electric & Gas (NYSEG) that it intended to place Westover Unit 8 in protective lay-up on March 19, 2011.

NYSEG and the NYISO analyzed whether the retirement of Westover Unit 8 could harm the reliability of the bulk and local electric transmissions systems in New York. To AEE2’s knowledge, no such reliability concerns were identified, said the Sept. 18 notice. “The Westover Unit 8 facility has been in protective lay-up status since March 19, 2011 and has not operated since well before that date,” the company added. Westover Unit 8 is an 84-MW, coal-fired facility.

Unless state Department of Public Service staff directs otherwise before Sept. 21, AEE2 intends to permanently retire Westover Unit 8 on that same day and soon thereafter transfer the facility to a company to dismantle and salvage it. AEE2 contemporaneously has notified NYISO and NYSEG of this plan.

AEE2 is also the owner of, and AES Greenidge LLC, a wholly owned subsidiary of AEE2, is the operator of the Greenidge Unit 4 located in the town of Torrey in Yates County. In September 2010, AEE2 served notice to the commission NYISO and NYSEG that it intended to place Greenidge Unit 4 in protective lay-up on March 19, 2011. To AEE2’s knowledge, no reliability concerns were identified related to the shutdown. Greenidge Unit 4 has been in protective lay-up status since March 19, 2011, and has not operated since well before that date. Greenidge Unit 4 is a 108-MW coal- and biomass-fired facility.

AEE2 said it now intends to permanently retire Greenidge Unit 4 on Sept. 21, and soon thereafter transfer the facility to a salvage company. Again, AEE2 has notified NYISO and NYSEG of this plan.
