Item 8.01 Other Events.

GenOn Energy, Inc. ("GenOn") previously disclosed in its Annual Report on Form 10-K for the fiscal year ended December 3, 2011, that it was continuing to evaluate the viability of environmental controls on its coal-fired units at its Avon Lake facility. The subsequent further analysis of the investment in such environmental controls indicates that the forecasted returns thereon are insufficient. Accordingly, on March 30, 2012, GenOn's subsidiary, GenOn Power Midwest, L.P. ("GenOn Midwest"), submitted a Deactivation Notification for the Avon Lake units 7 and 9 (732 MWs installed capacity) pursuant to Section 113 of the PJM Open Access Transmission Tariff. GenOn Midwest requested an effective Deactivation Date of April 16, 2015.
