OPERATIONAL FLOW ORDER – – REPORT

On February 13, 2025, due to forecasted colder than normal weather, anticipated market demand, and system operating conditions, Horizon issued an Operational Flow Order (“OFO”) effective for Sunday, February 16, 2025, at 9:00 a.m. Central Clock Time. This action was taken in accordance with Section 34.6 of the General Terms and Conditions of Horizon's FERC Gas Tariff (“GT&C”).

The OFO was issued to maintain and preserve the operational integrity of Horizon's system and was in response to the following operational factors: (1) maintain pressures for firm transportation deliveries; and (2) maintain operations to provide efficient and reliable firm service.

The OFO did not result in any curtailment of primary firm service. During the OFO, Horizon implemented daily and hourly take limitations for firm and interruptible Shippers (including Point Operators) at all delivery points. The OFO limited Shippers and Point Operators, on a daily basis, from taking volumes in excess of confirmed transportation nominations plus no-notice rights pursuant to third party balancing agreements at such delivery points, and on an hourly basis, to 130% of their firm service rights. Hourly rights for interruptible nominations were limited to 105% of the Shipper's interruptible nominations. Additionally, Shippers and Point Operators were required to flow more ratably during the gas day at all delivery points based on service priority and nomination cycles.

These measures were taken consistent with Horizon's Tariff due to sustained colder than normal weather. As the weather conditions moderated and the associated high gas demand declined, Horizon removed the OFO, effective at 9:00 a.m. on gas day Monday, February 24, 2025.

This posting complies with GT&C Section 34.6(h) of Horizon's Tariff to describe the specific operational factors which caused the Operational Flow Order to be issued and to be lifted.
