Summary PJM’s annual capacity auction was completed in August. This was the first year using the stricter capacity performance standards, which led to an increase in clearing prices. Exelon was the big winner in this year’s auction, with the potential to earn over $1.7B in capacity payments. Fewer new power plants bid into this year’s auction. This could be a positive sign for the long-run outlook of generation owners. For those who follow the electric utility industry, the PJM capacity auction is usually one of the big events on the calendar. (PJM is the regional transmission organization that essentially controls the operation of the electric grid from New Jersey to Chicago.) This year’s auction completed in August was no exception. The capacity auction was created a number of years ago to help support the reliability of the electric grid in a competitive market. The auction takes place three years before the capacity is needed, so this year’s auction was for the 2018/19 planning year. Electric demand fluctuates by time of day and by time of the year. There are some power plants that are needed for those few hours each year when demand is at its highest, but otherwise don’t have to run. These plants would never stay open if they were only paid for the few hours that they operate. The capacity auction essentially pays plants a standby fee to keep them open so that there is plenty of power available on high demand days. This fee is in dollars per megawatt of capacity for each day of the year. The size of the fee is determined in the capacity auction, and varies by location within PJM based on constraints in the electric transmission system. The following map shows the zones tested for transmission constraints in this year’s auction. Exhibit 1 (click to enlarge) Source: Brattle Group The arrows in the above map represent the connection between the parent zones and smaller sub-zones that might also have transmission constraints. For example, the MAAC zone has EMAAC as one of its sub-zones. EMAAC has its own sub-zones, including PSEG, which has its sub zone, PSEG-N. After the 2014 polar vortex caused reliability scares in PJM, changes, called capacity performance (NYSE: CP ), were made to the auction creating stricter eligibility requirements to participate. It also increased penalties for plants that receive capacity payments but are unable to perform when called upon during periods of peak demand. The creation of CP led to an increase in the clearing price for generation assets this year, as the higher cost of meeting the tighter eligibility requirements raised the auction bids for many participants. The clearing price of the RTO region of PJM (basically the areas in PJM without any transmission constraints) increased almost $45/MW-day over last year’s auction. Exhibit 2 Source: PJM Since this is the first year of CP, PJM only required 80% of the generation capacity to meet the new tougher standard. Eventually all capacity will have to meet the CP standard. Capacity in this year’s auction only meeting the old standard still received almost $150/MW-day in the RTO zone, which was close to a $30/MW-day increase in price. As you can see on the following map, only two areas priced separately due to transmission constraints this year, EMAAC and COMED. The prices in these zones were $50-60/MW-day higher than in the RTO. Exhibit 3 (click to enlarge) Source: PJM There are nine major generators that are impacted by the results of the auction. American Electric Power (NYSE: AEP ), AES Corporation (NYSE: AES ), Calpine (NYSE: CPN ), Dynegy (NYSE: DYN ), Exelon (NYSE: EXC ), FirstEnergy (NYSE: FE ), NRG Energy (NYSE: NRG ), Public Service Enterprise Group (NYSE: PEG ), and Talen Energy (NYSE: TLN ). The following chart shows the capacity each company holds inside PJM, and the zone where it is located.

You can also see that the majority of EXC’s capacity is in the COMED and EMAAC zones, which are the two zones that received higher prices this year because of transmission constraints. One thing to remember, though, is that having capacity in a region doesn’t necessarily mean you will receive payments for all of your capacity. Exelon actually issued a press release after the auction stating that three of its nuclear units (Quad Cities, TMI, and Oyster Creek), totaling 3,230MW of capacity did not clear the auction. The lost revenue from these plants not clearing is about $240M. Exelon already has plans to close Oyster Creek at the end of 2019. TMI and Quad Cities not clearing the latest auction probably means EXC will seriously be reviewing whether or not these plants should also be closed in the next few years. In general companies don’t publish which plants clear the auction because of competitive reasons, so it is difficult to know exactly which units will be receiving this revenue each year. Taking a company’s capacity in each zone and multiplying by the auction clearing price and by 365 days gives you an idea on how much potential revenue it could get from capacity payments. In this year’s auction, if you assume all of EXC’s capacity cleared at the latest prices, they would be receiving almost $2B in revenues. EXC is by far the biggest, but you can see the potential for the major players in the following table: Exhibit 5 (click to enlarge) Courtesy Garnet Research, LLC So without the three nuclear plants we know didn’t clear, Exelon still has the potential to earn over $1.7B of capacity payments. The above table also shows the biggest beneficiaries from the constraints in the electric transmission system. EXC obviously has the biggest benefit on a dollar basis, but PEG gets the biggest percentage benefit. Most of PEG’s plants are in EMAAC or in EMAAC’s sub-zones. Historically this has been a very good place to own power plants, because transmission constraints have impacted at least one sub-zone of EMAAC in all but one of the past capacity auctions. Exhibit 6 (click to enlarge) Courtesy Garnet Research, LLC So one thing to keep in mind when looking at PEG’s historical earnings is that they have been a big beneficiary of these transmission constraints. These constraints have been there for a long time, and with the difficulty in building new generation and transmission capacity, it is likely PEG will continue to be a beneficiary well into the future. This is actually the first time that COMED has ever broken out separately in the auction, which was partly driven by some power plant retirements. It remains to be seen if this year’s breakout was a one-time event, or the start of a trend. The ATSI zone, where the majority of FE’s assets are located, actually set an auction record with a $357/MW-day clearing price for 2015/16. But this year’s 2018/19 auction had ATSI just receiving the RTO price. So just because a zone received premium prices in an auction, it doesn’t mean this will continue for a long time. While EXC has the most potential revenue from the auction, on a percentage basis the impact to the bottom line is significantly greater for independent power producers Dynegy, NRG, and Talen. If you assume a $20 change in the auction clearing price across all zones, that all of each company’s capacity clears the auction, and a 40% tax rate on the incremental revenue, the impact is over 35% of NRG’s 2016 Street earnings estimate. The IPPs tend to trade more on EBITDA than EPS, and Talen Energy is actually the most sensitive on that metric. You can see the impact by company in the table below: Exhibit 7 (click to enlarge) Courtesy Garnet Research, LLC AEP, EXC, FE, and PEG all have sizable regulated wires businesses as part of their companies, which leads to the auction’s smaller bottom line impact for these names. While these names might not get as big a boost from the auction increase, their regulated business helps protect them when power markets suffer any downturns. Besides the increase in prices, this year’s auction may have brought additional positive news for competitive electric generators. Over the past few years record numbers of bidders have proposed adding new capacity to PJM. Last year almost 6,000 megawatts of new capacity cleared the auction, but this year less than 3,500MW was even offered. Exhibit 8 (click to enlarge) Courtesy Garnet Research, LLC This could be a sign that the economics of building a new power plant are becoming less attractive. The decrease in natural gas prices over the past few years has knocked down power prices and has been a big reason for the building binge, with generators trying to take advantage of a cheaper fuel source. If this buildout slows there would be fewer new power plants to compete with the current set of plants and would be supportive to companies that currently own capacity. This would be a positive for all generation in PJM, and could mean increased stability for power prices in the region. It also gives hope that the higher level of this year’s capacity auction might stick around for a while. Conclusion If the latest auction is a sign for a turnaround in the mid-Atlantic electricity markets, investors would benefit most by obtaining shares in DYN, NRG, or TLN. If investors want exposure to these markets, but with more regulatory assets to give some downside protection, then Exelon is probably the preferred name. FE and PEG are also similar to EXC, but they lack the added protection of Exelon’s geographic diversity.
