Effective January 2022, due to the availability of alternate tools for accessing interval data such as the Single User Multiple Request (SUMR) portal and a System to System Historical Interval Usage (StS HIU) platform, the interval files will no longer be published. If you have questions about access to these alternate tools, please contact FirstEnergy’s Supplier Services department using the link below. Additionally, if there are interval data needs outside of what is provided via Electronic Data Interchange (EDI), SUMR or StS, you can also send a request to the link provided as well. Please note, Letter of Authorization requirements and charges for requests made via the Contact Us form may apply. contact Supplier Services
