Increasing power generation natural gas consumption
Increasing Power Generation Natural Gas Consumption

Most other categories of natural gas consumption have had flat or decreasing usage trends!

Power generation is not the ideal gas customer
Power Generation is NOT the Ideal Gas Customer

Power generation gas use does not fit neatly into the gas contractual construct

  • Electricity demand, like gas demand, fluctuates and is subject to steep ramps, especially in winter

  • Increased wind and other intermittent resources don’t help

  • Fastest starting generation resources, generally are gas-fired combustion turbines which can go to full output in about 10 minutes or less

Some electric gas coordination issues
Some Electric/ Gas Coordination Issues

  • Language barrier

  • “Intermittency” of electric demand

  • Power generation use of interruptible service

  • Gas Day vs. “Electric Day”

  • Natural gas has some storage -- “just-in-time” fuel source

Firm vs interruptible service
Firm vs. Interruptible Service

Majority of PJM gas-fired generators have interruptible gas delivery service

  • Generators buy available firm service from others, via capacity release or bi-lateral arrangement

  • Use marketers to acquire a bundle of commodity and delivery

  • Risk curtailment for local delivery issues

    • Northern NJ – January 2013

    • Cleveland – July 2013

  • What PJM is doing: Discussing changes to market rules, dual fuel requirements, etc. as part of the PJM Gas Electric Senior Task Force

Gas day vs electric day
Gas Day vs. Electric Day

Issue: Timely gas nominations are due at 10 a.m. the day before (Day 1); electric “awards” are made at 4 p.m. the day before (Day 1) = 6 hours later; actual gas flow occurs starting at 10 a.m. on Day 2

What PJM is doing: Discussing potential for market timing changes (INGAA has signaled a willingness to change nomination timing)

Natural gas is a just in time fuel source
Natural Gas is a Just-in time Fuel Source

  • We’re used to having significant fuel at the generation site—coal piles, nuclear fuel, etc.

  • Gas moves at ~35 mph – it takes days to arrive from the Gulf of Mexico, although proximity to Marcellus/Utica helps

  • Pipeline can “line pack” to some degree, but advanced planning is necessary

  • Pipelines do have storage to some degree, but generators have to contract for it

What PJM is doing: Learning about gas pipeline capabilities and anticipating “big picture” look from the EIPC Gas Study

What is ferc doing
What is FERC Doing?

  • Bringing the industries together

    • Series of technical conferences

      • Some finger pointing, but also

      • Some very useful information exchange

    • Trying to exert leadership to bring solutions (Moeller)

  • NOPR on communications

    • Remove barriers between gas control and system operators to exchange non-public information

What PJM is doing:Supporting the FERC efforts through participation and comments

In the meantime
In the Meantime….

  • Pipeline expansion process is working (hopefully, in time to save New England!)

  • Large majority of gas-fired generators use interruptible service in PJM and other markets (and PJM has had some operational issues)

  • We continue to exchange large amounts of data via electronic bulletin boards, but is minimally useful in operations

  • Operators on both sides stand ready to respond to surprises that will pop up periodically (daily in New England!)


  • Power generation is a “double edged sword” for the gas business

    • Largest growth market

    • Potential to cause problems in operations

  • Working together, we can minimize the operational problems

    • Awareness of the limitations on each side

    • Increased real time communications across the aisle

    • Use of the demand side resources on each side
