This retirement notice will trigger a reliability review by MISO, which the Company expects to be completed in the first quarter of 2016. If MISO determines the plant is not needed for reliability, Dynegy expects the retirement to occur in mid-2016.Dynegy will be developing plans to minimize the impact on the approximately 90 employees at Wood River where possible, and to terminate operations in a safe and environmentally responsible manner. The Company will work with all of the relevant state, local, and community stakeholders to address the impact of the retirement of Wood River.
