OPERATIONAL FLOW ORDER – REPORT
10, 2021, due to sustained colder weather, market demand, and system operating
conditions, Horizon issued an Operational Flow Order (“OFO”) effective for Friday,
February 12, 2021 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

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.
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 on Horizon. 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 120% of their firm service rights. (On February 11, 2021, the hourly
firm service percentage was reduced from 130% to 120% before the OFO went into
effect due to changed system conditions). 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. The firm service percentage was reduced to 110% on
Thursday, February 17, 2021 at 9:00 a.m. Central Clock Time.
measures were taken consistent with Horizon's Tariff due to sustained colder
weather and market demand. 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 22, 2021.
