Section 8 - Other Events
Item 8.01. Other Events

Exelon Generation Company, LLC (Generation) owns a 42.59% interest in Units 1 and 2 at the Salem Nuclear Power Plant (Salem). PSEG Power LLC (PSEG) is the operator of Salem and has the decision making authority to retire Salem. As previously disclosed, on December 19, 2018, PSEG filed applications with the New Jersey Board of Public Utilities (BPU) seeking approval for Salem 1 and Salem 2 to participate in the BPU’s Zero Emission Certificate (ZEC) program established in May 2018. On April 16, 2019, PSEG submitted to PJM deactivation notices for Salem 1 and Salem 2 and final must-offer exception requests with respect to PJM’s Reliability Pricing Model must-offer requirement in connection with the 2022/2023 capacity auction that is currently scheduled for August 2019. If Salem 1 and Salem 2, as well as PSEG’s Hope Creek plant, are selected to participate in the ZEC program, PSEG has indicated that it would withdraw the exception requests and deactivation notices for Salem 1 and Salem 2. A decision by the BPU on which nuclear plants, if any, have been selected to participate in the ZEC program is expected on or about April 18, 2019.
