Why King Coal Isn't Dead


The hits keep on coming for the coal industry since my post earlier this week about the “War on Coal”. On Wednesday the Senate voted down Senator James Inhofe’s resolution to scrap the Environmental Protection Agency’s (EPA) Mercury and Air Toxics Standard, by a vote of 46 yes to 53 no.   

Perhaps the biggest and most surprising news from the Senate's deliberations was a speech by Senator Rockefeller.  The Democrat from West Virginia rebuked the coal industry he represents, and told them to "face reality" rather than blame their troubles on EPA.  It was a powerful, honest speech that you should check out if you have 15 minutes to spare (or check out his editorial). 

The bad news continued for the coal industry on Thursday, as Arch Coal announced 750 job cuts in Appalachia because of lower demand for coal-based electricity.  In other words, it was a decision based on the current comparative economics between coal- and natural gas-fired generation. 

So with all this bad news for coal, is King Coal really dead? Or did natural gas put him on life support and the new EPA rules are the coup de grace.

As I mentioned in my previous post, the proclamations of coal's death - imminent or otherwise - because of natural gas prices and regulations, are overblown.  Coal will remain a significant contributor to our nation's electricity mix for the next 10-20 years. Here's why:

Most of the coal-fired power plants scheduled for retirement in the next five years are older, smaller and inefficient.  That combination makes it harder for utility planners to justify spending millions of dollars on environmental controls to maintain unit operation.  SNL Financial is reporting that announced retirements for 2012-2016 total roughly 21,000 megawatts (MW).  In the scatterplot below, you can see that most of the retiring units are below 300 MW and were built 50 or more years ago.

Many of the plants do not operate at high utilization rates. In total, the retiring units produced just 5% of the total 2011 coal-fired electricity, or approximately 2% of all electricity in 2011.  Not an overwhelming amount.  The real work-horses of the coal fleet are the newer and larger units.  Most of these units already have environmental controls because the units are more efficient and the economies of scale for environmental controls make the projects economically justifiable.  The larger coal plants produce the brunt of coal-fired generation, and will continue to operate in the next 10-20 years.

Just how much coal capacity will remain? The Energy Information Administration’s (EIA) estimates in its Annual Energy Outlook 2012 Early Release takes into account approximately 21,000 MW of coal retirements and estimates that 288,000 MW of coal will remain operational in 2015. 

Historically, EIA’s estimates are conservative and often criticized as such. If we assume 70,000 MW of total coal retirements, as estimated this week by ICF, that leaves us with roughly 240,000 MW of operational coal plants.  That is more than any other type of generation plant. As a comparison, EIA estimates the 2015 natural gas combined cycle capacity at roughly187,000 MW.

Here are some quick back-of-the-envelope calculations showing why coal will still be a significant player in the electricity market:  240,000 MW of coal would produce roughly 34% of our electricity generation in 2015.[1] Under that scenario, the electricity industry would consume about 670 million tons of coal in 2015. [2].[3]

Coal’s market share (and influence) are certainly diminished, but there's a long way to go before "King Coal" is etched into a headstone.

[2] Assumes a 10.25 MMBtu/MWh heat rate and an average heat content of 10,000 Btu/lb of coal.
[3] That would be the lowest consumption level since the 1980s. The ICF report, however, finds that coal consumption will remain flat through 2020, which implies the remaining coal units would have a higher capacity factor than the 62% I assumed.

Inhofe v. Jackson: Who's Right About What's Ailing Coal?


I try my best to ignore the political rhetoric and fallacies that are so pervasive inside the DC Beltway, but this time I cannot.  

You know the routine: a representative from one political party says something – doesn’t matter if it’s divisive or innocuous – about an issue, which elicits an adamant rebuttal from the opposing party.  Mix in a hefty portion of disinformation, sprinkle with some sugarcoated facts, turn the spin cycle on high, and throw in the suffix “-gate” for good measure. Then repeat the process as necessary indefinitely.  

At issue here is an upcoming vote about air pollution regulations, and the latest bout in what some have dubbed the “War on Coal” (coal-gate would just confuse too many people). Many are opining about who (or what) is “killing” coal.  Some have blamed the Environmental Protection Agency's (EPA) regulations for creating a burden too large for coal power plants and the mining industry to bear.  Others say coal plants are at-risk for retirement because of market conditions and competition from low natural gas prices. 

In an interview last week, EPA Administrator Lisa Jackson cited low natural gas prices as the culprit behind coal’s struggles, and said: “So in my opinion the problem for coal right now is entirely economic.”  Senator James Inhofe (R-OK) fired off a letter to Jackson, criticizing her comments and blamed EPA for the coal industry’s struggles. (I'm looking for a link to the letter that does not reside behind a pay-wall, and will post it as soon as I find one).  Inhofe suggested that Jackson substitute her “judgment for that of qualified corporate planners.” 

Since I consider myself one of those qualified corporate planners – having worked at one of the nation's largest electric utilities (and coal consumer) doing economic analyses for environmental compliance and power plant retirement decisions – I thought it would be good for me to the evaluate the latest spat in the enduring battle between Inhofe and EPA.

Before sizing up their arguments, let me first digress and channel Mark Twain to say that the reports of coal’s death are greatly exaggerated.  I will substantiate this statement in a future blog post, but in my opinion, coal will remain a significant contributor to the nation’s electricity mix for at least the next 10-20 years despite the challenges the industry currently faces.    

So back to the action: who’s right? Is it natural gas prices or EPA regulations that are putting the pressure on the coal industry?

Assessing Lisa Jackson’s Assessment

In an interview with Grist last week, Lisa Jackson described coal’s problem as being “entirely economic.” Technically, Administrator Jackson’s statement is correct. The comparative economics between coal and natural gas clearly favor natural gas in both the “short-run” and “long-run” (definitions for non-econ wonks).  Jackson’s statement, however, is misleading because it implies that natural gas prices are the root cause.  Yes, natural gas prices are the predominant factor affecting the viability of coal plants, but regulations play a role as well.

Here is why: prior to the new environmental regulations, electricity planners had three basic options for their “uncontrolled” (i.e. without environmental controls) coal power plants. The options were:
  1. Continue to operate the coal plant without environmental controls
  2. Continue to operate the coal plant and invest in environmental controls
  3. Retire the coal plant and replace with a new power plant or purchase replacement generation


The goal of electricity planners is to minimize total costs, and therefore in the absence of environmental requirements, they would tend to pick Option 1 – as long as the plant is in good working condition and its revenues exceed its costs.  This is because Option 1 already has sunk costs (the power plant itself), while Options 2 and 3 require significant capital investments.

The adoption of new environmental regulations changes the evaluation because Option 1 is non-compliant and is therefore no longer viable.  Electricity planners are left with two basic options: control the plant or retire it. The low cost of natural gas power plants and fuel coupled with the age and efficiency of uncontrolled coal plants make retiring coal units (Option 3) an attractive economic option.  So technically Lisa Jackson is correct, coal’s issue is an economic one, but part of the reason is because the regulations are changing the equation.

Senator Inhofe “killing” it?

Although Senator Inhofe clearly believes regulations are a significant problem for the coal industry, he opened his letter to Lisa Jackson by subtly admitting abundant natural gas plays a role in the problems facing the coal industry. He then claims Jackson’s statement “distorts economic realities.”  Ironically, Inhofe’s letter is also guilty of distorting reality.

Inhofe’s letter notes that Jackson’s assessment contrasts’ starkly with comments from EPA Region 1 Administrator Curt Spalding.  At first read, I was shocked by Spalding’s “comments” because I thought Inhofe had found the smoking gun proving an active conspiracy at EPA to “kill” the coal industry.   Here is the excerpt from Inhofe’s letter I found shocking: “…Spalding who openly admitted that EPA regulations, are in fact, killing coal and that EPA consciously and deliberately made the decision to do so… In his recent comments to a Yale University gathering caught on tape, Administrator Spalding said…” 

Then I read Spalding’s comment and watched the video of his talk at Yale (provided by Inhofe, watch here).  Instead of seeing some grainy footage of a flippant Spalding making disparaging remarks about the coal industry, I saw an honest assessment of how difficult it was for the EPA to make the regulations, especially when accounting for the potential impacts on people and communities.  Spalding never mentioned “killing”; the insinuation and emphasis was all Inhofe’s. 

The letter later stresses the need to take “company statements regarding the motivations for plant closures seriously,” and cites FirstEnergy’s decision to retire about 2,700 megawatts of coal-fired generation because of environmental regulations. FirstEnergy is an excellent company, but I found their decision peculiar, and I am not convinced that environmental regulations are the sole cause of the retirements. 

The compliance deadline for the new Mercury and Air Toxics Standards is mid-2015.  If the environmental rules were to blame for the retirements, why would they shut the plants down in September 2012 rather than run the units up until the compliance deadline?  The reason is economics, and supply and demand. 

Many of the units slated for retirement are older, smaller and inefficient (although surprisingly, there were a few younger, larger units on the list).  The units are likely uneconomic or marginally profitably to operate today.  Without access to FirstEnergy’s analysis, the simplest way to assess the value of the units is to look at their recent capacity factors.[1]  A high capacity implies the unit is cheap to operate and valuable, while a low capacity factor means a unit is marginal and more expensive to operate. Several retiring units operated at low capacity factors the last few years (see graphs below) due to increased competition from natural gas units, and decreased electricity demand from the recession.  The low capacity factors are a result of economic dispatch, not environmental regulations.






The supply and demand of power plant capacity is the other potential economic driver behind FirstEnergy’s decision to retire the units earlier than the compliance deadline. FirstEnergy’s remaining fleet suddenly becomes more valuable by retiring megawatts early and creating capacity scarcity. In PJM’s May capacity auction, capacity prices in FirstEnergy’s region cleared at $357MW/day compared to $167 MW/day for the remainder of the PJM market.  

Like Jackson’s comments, Inhofe’s letter is misleading and does not tell the entire story. It is evident that Inhofe’s letter is fraught with manipulative statements, and how powerful his (and the coal industry’s) use of terms like “war” and “killing” can be.  Unfortunately, most people do not have industry experience or the time to dig through articles, videos, and transcripts to find truth in the debate.

They are both right… and wrong

So who is right?  In my opinion, Administrator Jackson and Senator Inhofe are both right, and wrong.  Low natural gas prices, lower electricity demand, and environmental regulations are all contributing to coal’s struggles.  But natural gas is the predominant factor, not the EPA’s rules (this conversation does not happen if natural gas prices were $8/MMBtu instead of $2.50/MMBtu).

Is there middle ground?

On Wednesday, Senator Inhofe intends to bring the Congressional Review Act to vote. The ACT attempts to provide the coal industry relief by striking down EPA’s new Mercury and Air Toxics Standards.  In my opinion, that’s harsh move. Instead I’d support the reasonble alternative measure set forth by Sen. Lamar Alexander (R-TN) and Sen. Mark Pryor (D-AK) to move the MATS compliance date from 2015 to 2018.  The compromise would give the electric sector, affected communities and associated industries the ability to spread out their investments, and provide enough time to transition away from coal.

Here is to hoping cooler heads prevail.
