Aging generators with deliberate maintenance are staying on-line, however this might lead to “catastrophic” failure afterward.
DALLAS — As temperatures throughout Texas proceed to come close to or move all-time information this summer time, demand on the power grid has too.
On Monday, ERCOT confirmed demand setting a brand new report with a fair larger report anticipated Tuesday adopted by a 3rd new peak on Wednesday, with demand forecast at 81.6 gigawatts (GW).
For perspective, prior to 2022, the all-time report was 74.8 GW set in 2019.
“What we’re experiencing right now is going to be our new normal for a while,” mentioned Michele Richmond, the manager director of Texas Competitive Power Advocates.
TCPA represents 60% of all era on the grid and says the generators holding up the grid are getting older.
Last week, ERCOT issued two conservation notices, however this week, regardless of the information, they don’t besides any due to stronger wind and fewer thermal outages.
“We are currently doing everything we can to make sure that that doesn’t occur,” Richmond mentioned.
Demand this excessive, and quickly trending larger, isn’t sustainable with out change.
“If you’re not paying attention to climate and you’re operating a grid, you’re going to be unprepared,” mentioned Doug Lewin, a clear power marketing consultant with Stoic Energy.
ERCOT’s starting of the yr forecast was off considerably. The grid operator predicted a July demand peak of 74.9 GW. Lewin and Richmond each fear about outdated generators which have been compelled to postpone scheduled maintenance this yr to sustain with the excessive demand.
“If you’ve got an old car, you don’t want to put off your maintenance because then you risk something catastrophic breaking,” Richmond mentioned. “It’s the same kind of situation for these aging machines.”
“You’re taking your 50-year-old car, not getting the oil changed and running it at 80, 90, 100 miles an hour every day,” Lewin mentioned. “Something’s going break.”
Where the pair differ is on options. Richmond says the Public Utility Commission wants to change priorities from affordability to reliability, that means pushing for extra thermal era than wind or photo voltaic.
“Getting this market design change to emphasize reliability is absolutely critical to the future of our grid,” she mentioned.
“It would be folly to choose one over the other,” Lewin says of reliability over affordability. “That is a false choice.”
Lewin says payments would skyrocket past the sharp beneficial properties clients are already feeling due to the excessive value of constructing new thermal generators.
“Any vision for the future for the Texas grid or any other grid that just says affordability isn’t a concern is ludicrous and crazy,” he mentioned.
His imaginative and prescient is extra photo voltaic and extra costal wind and, equally vital, higher power effectivity.
This week, Texas needs to be within the clear, however any outage now or later this yr would once more create questions on the way forward for the grid within the warmth or the chilly.
