EIA Is Damaging Its Analytical Repute With Coal Forecasts


Print Friendly, PDF & Email

The professional-coal sentiments of the Trump administration are well-known; sadly, that boosterism clearly is starting to seep into the analytical work of the Vitality Data Administration.

 In a late March Immediately in Vitality piece on the EIA web site, the group reprinted three logic-defying graphics on coal’s future position within the U.S. electrical era sector (the three have been initially printed in EIA’s 2018 Annual Vitality Outlook launched in February).

The primary, as EIA wrote, exhibits that there might be “just about no [coal plant] retirements from 2030 via 2050.” Given the 50 gigawatts of capability which have been shuttered simply since 2011, and the 65 GW of further capability the administration expects will shut down via 2030, projections of zero additional closures past that pressure the bounds of believability. There’s rising assist all through the enterprise neighborhood for a low-carbon future,  and rising numbers of utilities are coming ahead with coal phase-out plans (see my earlier tales right here and right here). The development is to not preserve that era capability, however to shut it.

That flat-line projection additionally overlooks a key level in regards to the age of the U.S. coal-fired producing fleet—a degree that EIA itself made final 12 months. The coal era items in america are getting older: In accordance with EIA information, 88 p.c of the nation’s coal capability was constructed earlier than 1990, that means that in 2050 even the youngest crops could be 60 years previous. Extra telling, EIA stated, the coal era fleet’s capacity-weighted age in 2017 was 39 years. Provided that, projecting that there might be no retirements after 2030 merely borders on the ridiculous.

Compounding issues, EIA additionally projected in a leap of counter-intuititve logic, that because the coal fleet ages, its common capability issue will climb again roughly to 70 p.c—a degree not seen for the reason that mid-2000s when the crops have been a lot youthful (see the graphic under)—after which preserve that efficiency all through the tip of the of its 2050 forecast interval. There are two main issues with this projection. First, it ignores age-related deterioration that impacts all older crops.

Second, it doesn’t bear in mind the operational adjustments which have taken place within the utility sector up to now 10 years, notably the surge of latest renewable era assets that don’t have any gas prices and the shale growth that has pushed pure gasoline costs down and guarantees to maintain them low for the foreseeable future.

The subsequent graphic (which was taken from an April 2016 Immediately in Vitality article) illustrates the operational adjustments that EIA’s present projection fails to include. In 2005, coal crops by and huge have been operated as baseload amenities, operating primarily 24/7 all 12 months. Reflecting this, roughly 270 crops that 12 months posted capability elements of 70 p.c or increased. By 2015, this had all modified and fewer than 100 crops recorded capability elements that top.

The system merely doesn’t function in the identical trend because it did 10 years. Right here, the surge of wind era within the Midwest is a good instance. The area’s wind useful resource tends to blow hardest within the in a single day hours and because it has no gas value it’s dispatched first, forward of the coal crops that previously would have offered that electrical energy.

It is usually essential to notice that in 2005 when the coal fleet’s capability issue was 67 p.c (There’s a discrepancy between the information within the two EIA graphics, nevertheless it doesn’t affect this evaluation.), there have been solely roughly 100 items working at lower than a 40 p.c degree. By 2015, the variety of crops at that degree had climbed to virtually 200.  Overcoming that drag on the general fleet’s efficiency could be tough, at greatest.

Briefly,  getting the system as an entire as much as a 70 p.c capability issue is nothing greater than a pipe dream. Conveniently, nonetheless, these truth-stretching assumptions permit EIA to, you guessed it, venture that U.S. coal manufacturing will stay primarily flat, at roughly 750 million tons yearly, all the way in which out to 2050 (see graphic under).

Sadly, wishing one thing so doesn’t make it so. Anybody searching for actual evaluation of what’s going on within the coal trade goes to have to start out trying elsewhere.
