Oil Saves New England

Oil Saves New England

During the coldest days this past January, the New England grid was on the brink of disaster, and only pre-planning by ISO-NE, with emergency actions by the Coast Guard and luck kept the lights on.

The pre-planning by the New England Independent System Operator consisted of ensuring there were sufficient duel burning, i.e., oil and natural gas power plants, with oil stored on site, available for extended periods when natural gas would not be available for meeting increased demand for electricity.

Homeowners have first call on natural gas and power plants could not be sure of having adequate supplies when cold weather resulted in increased loads. Their natural gas supplies could be interrupted since homeowners came first.

Oil was to provide the fuel needed to keep the grid up and running.

But as the cold weather worsened, oil supplies were rapidly depleted, and resupply was necessary. But the waterways were frozen and the Coast Guard was called upon to open them using ice breakers so that refueling vessels could reach the power plants in need of replacement oil.

Bridges were raised during rush hour to allow these vessels to pass so the oil could reach its destination in time.

Luck asserted itself as the weather finally broke, just in time to allow normal operations to resume. Power plants were scraping the bottom of the barrel of their oil supplies.

Unreliable wind and solar made very little contribution to sustaining the grid. More on wind and solar in another article.

The following charts from ISO-NE report shows what happened.

These conditions prevailed from December 28 through January 9.

 

Oil provided the fuel that saved New England from a grid disaster this past January. On January 6, it supplied 36% of the electricity for the New England grid.

But luck stepped in as fuel oil supplies were being depleted. By January 9, only 19% of total possible supply in New England was remaining.

While the days of remaining supply at a typical power plant, as shown by ISO-NE, was down to about one day on January 9.

This is a success story, of pre-planning, emergency action and luck.

But we shouldn’t have to rely on luck to keep the lights on.

There are some general conclusions that can be reached from this experience.

  • Nuclear power plants should not be forced to close before the end of their useful lives
  • Unreliable and expensive wind and solar cannot provide the electricity needed during bad weather
  • Pipeline capacity constraints need to be alleviated, by building more pipeline capacity. While this is a serious problem for New England, it is an emerging, though isolated problem elsewhere.
  • DOE’s proposed rule, rejected by FERC, for maintaining a 90 day supply of fuel on site was vindicated by this event.

(It should be noted that FERC has objected to the ISO-NE approach of paying for one type of fuel, and ISO-NE will not be able to repeat what it did this year. It will try a new, untested Pay for Performance approach next year.)

  • The hysteria of global warming and climate change are resulting in bad economic decisions

  1. Of course, you know the anti-nuclear proponents will simply twist this into a pro-fossil argument. Almost out of oil? Build more on-site and offsite storage. Problems with delivery? Build more pipelines. Diversity of fuel supply means nothing to these people. And things like fuel diversity, reliability, capacity factor, are way over the heads of most of the public. Most people simply assume that the lights will come on when the switch is thrown simply because, well, they always do. Until they don’t. Then they’ll scream bloody murder, but it will be too late.

    But they will hear something, a soft, echoing phrase spoken by me, among others: “I told you so…”
