On April 14, 2017, a 202(c) emergency order was issued authorizing Grand River Dam Authority (GRDA), a state-owned utility in Oklahoma, to operate its Unit No. 1 at the Grand River Energy Center (GREC) as needed to provide dynamic reactive power support in the GRDA service area until replacement generation capacity at GREC becomes available. Below are the petition that GRDA sent to the Department of Energy on April 11, 2017, and the emergency order that the Department of Energy issued on April 14, 2017.
