Last Saturday, the Wall Street
Journal published an article that would seem to be more likely to appear in
that other august publication, The Onion. It was titled “As
Texas Went Dark, the State Paid Natural-Gas Companies to Go Offline”.
Of course, it would have been much
better for the citizens of Texas if the article had appeared in The
Onion, but unfortunately that wasn’t the case. This is something that
actually happened, although the headline was wrong in saying that “the State” made
these payments.
In fact, it was the Electric
Reliability Council of Texas (Ercot) that bears most of the blame for this sordid
event (on the other hand, they deserve praise for averting what could have been
a much more serious crisis, due to the actions they took during what must have
been an incredibly tense nine-minute period early in the morning on Monday February
15, which I described in this
post. But on the other other hand – I believe I’ve run out of hands! – they
deserve lots of blame for maintaining the $9,000/mwh electricity price after
the Texas Public Utility Commission decided that the current $1,200/mwh market price
wasn’t quite high enough for them later that same day. Ercot maintained that
price through Friday, even though the market price went down to its normal
level of about $25/mwh by Thursday. That sordid story is described in this
post).
How did this happen? If you’re
familiar with the power industry, you probably know about “demand response”. This
is the name for programs that incent power users to curtail their use of power
during periods of high demand or constrained supply. This particular Ercot
program paid industrial users to shut down operations.
You can probably see the problem
already: At the height of the crisis on May 15, Ercot activated their demand
response program, believing this to be a lesser evil that would avert a greater
evil: mandatory power shutoffs (with no compensation, of course).
I don’t need to tell you that the
DR program didn’t work, and mandatory shutoffs happened anyway. In fact, ultimately
four million Texans went without power, many for days. But in theory, this was
the right thing to do, even though it ultimately didn’t fix the problem of a
shortage of power relative to demand (which had spiked because most Texans heat
with electricity). However, it’s likely that the activation of the program made
the total problem much worse, since some of the participants in the DR program
were natural gas producers and gas distribution (pipeline) companies. And a lot
of power plants in Texas run on natural gas.
Moreover, a lot of gas production –
e.g. in the Permian Basin – was already shut down because the wellheads froze.
And even if a wellhead wasn’t frozen, it’s possible that the pipeline carrying its
gas to power plants and other users was frozen, because in Texas – unlike in
colder climes – water vapor isn’t usually removed from the gas before it’s put into
the pipeline (maybe that will change now). But now the activation of demand response
reduced gas supply and distribution capacity even more, since the companies in
the program curtailed operations.
Of course, these gas companies
could have resumed production at any time (and certainly, given that the price
of natural gas had spiked during the crisis, along with the power price, they
certainly should have been tempted to do that). However, the rules of the
program meant they would be penalized if they did that.
Of course, if somebody had been
thinking at the Texas PUC during this crisis (a pretty tall order, it seems.
PUCT regulated the program, although Ercot was in charge of implementing it),
they might have thought that maybe – just maybe! - it would be a good
idea to suspend these penalties for gas companies. This would allow them to
provide gas to their customers, including gas-fired power plants. And that
could allow the plants to reopen and help end the crisis more quickly than it ultimately
did.
And here I have some good news: PUCT
did actually do that! The WSJ says they “…issued a memorandum that said
if a facility resumed normal operations ‘because it was providing a critical
service or product …enforcement discretion will be exercised.’”
But I also have some bad news: The
PUCT didn’t issue that memorandum until Friday, four days after the DR program
was activated. And at 9 AM on Friday, “the blackout officially ended and Ercot
allowed participants to resume their use of electricity.”
Oh well, it’s the thought that
counts.
