In accordance with the implementation of Act 40, all solar facilities located outside of the state of Pennsylvania are assigned a Tier I non-solar certification number in the format of PA-XXXXXX-NSTI-I (“NSTI”). 

Out-of-state solar credits from generation prior to and through the month of October 2017 will remain eligible for PA AEPS solar compliance until those credits are retired or expire. These certificates will maintain their certification of PA-XXXXXX-SUN-I (“SUN”). Credits are valid the year they are generated through the subsequent two years. 

EDCs/EGSs with contracts for out-of-state solar PV credits should follow the guidelines issued in the May 16, 2018 Secretarial Letter to file a petition with the PUC. If you will be retiring out-of-state (NSTI) credits with an approved order from the PUC, please provide a copy of the order and a spreadsheet of credits that you will be retiring via email so we can confirm their approval for retirement by the PUC.
