The Federal Energy Regulatory Commission on Thursday approved a rule to improve coordination of the wholesale natural gas and electric market schedules, adopting two gas scheduling changes but declining to move the start of the gas day to 4 a.m. CT from 9 a.m. CT (RM14-2).
Order 809 revises the interstate gas nomination timeline, moving the timely nomination cycle deadline for scheduling gas transportation to 1 p.m. CT from 11:30 a.m. CT. It also adds a third intraday nomination cycle, which should allow shippers to better adjust to changes in demand.
Thursday’s order was a win for the Natural Gas Council, which last year rejected an earlier start time, saying it would cause safety and contractual problems. The group represents nearly all the companies that produce and deliver gas, including members of the American Gas Association, America’s Natural Gas Alliance, the Independent Petroleum Association of America, the Interstate Natural Gas Association of America and the Natural Gas Supply Association.
The failure to reach consensus between the electric and natural gas industries was noted in a FERC staff presentation at the commission’s open meeting Thursday. “The … final rule finds that there has not been a showing that the benefits of changing the nationwide gas day from 9 a.m. CT to 4 a.m. CT sufficiently outweigh the potential adverse operational and safety impacts and costs of making such a change,” staff said.
Growing Pains
The growth in natural gas-fired generation has strained pipeline capacities and provided operational challenges to grid operators. Two issues were spotlighted: communications between generators and natural gas transmission operators, and gas-electric scheduling.
In November 2013, the commission approved a rule allowing gas pipeline operators to exchange non-public operational information with RTOs. (See FERC OKs Gas-Electric Talk.)
A 2013 report by the North American Electric Reliability Corp. said that the disparity in schedules meant that “electric generator nominations, with their relatively large gas loads, are based upon estimates by the individual fuel planners of each Generator Owner (GO) between 24 and 36 hours in advance. The issue could be magnified when scheduling on a Friday, since gas markets are closed for the weekend.”
The new rule “illustrates how the commission can engage with industry and stakeholders in a collaborative process to offer real improvements in our natural gas and electricity markets,” Commissioner Cheryl LaFleur said in a statement.
The American Gas Association, which represents more than 200 local distribution companies, praised the ruling.
“I am pleased to see that FERC will maintain the 9 a.m. CT start time, a positive step that recognizes what is in the best interest of both gas and electric customers,” CEO Dave McCurdy said. “We appreciate FERC’s attention to the coordination between gas and electric systems, and believe this is a critical issue that needs attention, but changing the gas day was not a step that would have ultimately improved this coordination.”
Retreat
But Thursday’s order was a retreat from the commission’s March 2014 Notice of Proposed Rulemaking, which proposed the 4 a.m. start time. (See FERC: Six Months to Move Gas, Electric Schedules.)
The commission approved the NOPR on a 3-1 vote with LaFleur, Commissioner Philip Moeller and former Commissioner John Norris in support. Commissioner Tony Clark dissented, saying he wanted to give the industries more time to reach consensus. Since then, the commission has added Commissioners Norman Bay and Colette Honorable.
The rule becomes effective 75 days after publication in the Federal Register. Each ISO and RTO must come up with tariff revisions to either coordinate its day-ahead market with gas pipeline scheduling changes or show why changes shouldn’t be implemented.
