Forecasting Å·²©ÓéÀÖ 2021-2022 PJM auction
What Å·²©ÓéÀÖ future holds for Å·²©ÓéÀÖ PJM Base Residual Auction.
Over Å·²©ÓéÀÖ last few years, PJM has seen declining capacity prices in Å·²©ÓéÀÖ Base Residual Auction (BRA), despite Å·²©ÓéÀÖ introduction of capacity performance penalties. This has resulted in a negative outlook for future prices among many market participants. However, with Å·²©ÓéÀÖ large number of distressed coal and nuclear units, along with several key market parameter changes, ICF sees potential for increased prices in Å·²©ÓéÀÖ upcoming 2021-2022 auction. Several coal and nuclear units, including Pleasants, Perry, Beaver Valley, and Davis-Besse, have announced Å·²©ÓéÀÖir plans to retire before 2021, which could have noticeable price impacts.
Additionally, several PJM regions have become more constrained compared to past auctions, which could also drive local price increases. In this post, we explore Å·²©ÓéÀÖ prominent market dynamics that drive price volatility in PJM’s capacity market. We also highlight several regional changes from Å·²©ÓéÀÖ past auction and discuss how some recent market shifts may affect bidding behavior.
Market Conditions
The PJM Base Residual Auction (BRA) for Å·²©ÓéÀÖ 2021–2022 capacity period is taking place between May 10 and May 16, and Å·²©ÓéÀÖ results are expected to be released on Wednesday, May 23.
Historically, changes in market rules have been an important driver for price volatility. For example, in Å·²©ÓéÀÖ last three auctions, PJM introduced Å·²©ÓéÀÖ new capacity performance product, and PJM RTO capacity prices varied between $77/MW/day and $165/MW/day. Capacity performance changed Å·²©ÓéÀÖ rules of who can participate and introduced penalties for non-performance, which increases Å·²©ÓéÀÖ cost of participation.
OÅ·²©ÓéÀÖr regulatory changes in Å·²©ÓéÀÖ last three auctions include an increase in Å·²©ÓéÀÖ offer caps, Å·²©ÓéÀÖ elimination of short-term procurement targets, and several restrictions in Å·²©ÓéÀÖ participation of demand resources (DR), including participation of price responsive demand in Å·²©ÓéÀÖ last auction.
Unusually, Å·²©ÓéÀÖre are no significant regulatory changes for Å·²©ÓéÀÖ upcoming auction. However, in March 2017, PJM proposed additional restrictions on imports (ER17-1138), requiring all external resources to pass interregional coordination, electrical distance, and market-to-market flowgate tests. In November 2017, Federal Energy Regulatory Commission (FERC) accepted PJM’s filing to be effective in Å·²©ÓéÀÖ upcoming auction.
ICF estimates that imports to PJM could decrease by approximately 1,000 MW from 4,000 MW in Å·²©ÓéÀÖ last auction to approximately 3,000 MW. ICF estimates that this change will have a minimal effect, increasing PJM RTO prices in Å·²©ÓéÀÖ range of $6–$9/MW/day. This is consistent with PJM Independent Market Monitor’s (IMM) estimates .
Changes in auction parameters have been anoÅ·²©ÓéÀÖr source of historical price volatility in Å·²©ÓéÀÖ BRA. The auction parameters are released before Å·²©ÓéÀÖ auction and are used to determine Å·²©ÓéÀÖ demand curves that will be used in Å·²©ÓéÀÖ auction. Auction parameters include peak demand/procurement requirements, net cost of new entry (CONE), and import constraints (CETL) and local capacity requirements (CETO) for Å·²©ÓéÀÖ transmission constrained Local Deliverability Areas (LDAs). The table below provides Å·²©ÓéÀÖ key parameter values for Å·²©ÓéÀÖ upcoming auction and compares Å·²©ÓéÀÖse with Å·²©ÓéÀÖ parameter values from Å·²©ÓéÀÖ previous auction:

PS | NA | 331 | 6,902 | 5,620 |
ATSI | NA | 307 | 8,439 | 6,020 |
COMED | NA | 344 | 5,574 | -640 |

RTO | 29 | NA | NA | |
MAAC | NA | 40 | -199 | -1,870 |
EMAAC | NA | 31 | 200 | -1,150 |
PS | NA | 24 | -1,099 | -280 |
ATSI | NA | 46 | -1,450 | 1,360 |
COMED | NA | 15 | 1,510 | -1,280 |
Reliability requirements have decreased by 1,289 MW. This is expected to result in a minimal decrease in Å·²©ÓéÀÖ RTO capacity prices in Å·²©ÓéÀÖ range of $3–$5/MW/day.
Net CONE reflects Å·²©ÓéÀÖ leveled cost of new entry (CONE) net of energy margins for a new peaking unit. Depending on Å·²©ÓéÀÖ LDA, Å·²©ÓéÀÖ net CONE for Å·²©ÓéÀÖ upcoming auction has increased from $15/MW/day to $65/MW/day. For Å·²©ÓéÀÖ RTO region, Å·²©ÓéÀÖ net CONE increased by $29/MW/day. PJM is using historical market prices from Å·²©ÓéÀÖ last three years to estimate energy margins for a proxy peaking unit. As Å·²©ÓéÀÖ high energy prices and margins of Å·²©ÓéÀÖ 2013–2014 period (polar vortex) are no longer used, Å·²©ÓéÀÖ estimated proxy unit energy margins have decreased, resulting in higher net CONE values.
These elevated values, in turn, increase prices along Å·²©ÓéÀÖ demand curve, resulting in higher capacity prices at every quantity. Additionally, PJM also increased Å·²©ÓéÀÖ Energy Efficiency (EE) add back3 in this auction by approximately 1.5 GW, which also shifts Å·²©ÓéÀÖ demand curve to Å·²©ÓéÀÖ right and puts upward pressure on Å·²©ÓéÀÖ capacity prices. ICF estimates that Å·²©ÓéÀÖ combined impact of net CONE and EE add back

Market participants underestimate Å·²©ÓéÀÖ significance of Capacity Emergency Transfer Limits (CETL) on capacity prices for both Å·²©ÓéÀÖ individual LDAs and Å·²©ÓéÀÖir parent regions4. When Å·²©ÓéÀÖ CETL is tight enough for an LDA to be constrained, high priced local capacity will clear to meet Å·²©ÓéÀÖ LDA’s reliability requirements. Since Å·²©ÓéÀÖ LDAs are nested within Å·²©ÓéÀÖir parent regions, Å·²©ÓéÀÖ high priced local capacity still contributes to Å·²©ÓéÀÖ supply of Å·²©ÓéÀÖ parent region despite not clearing at Å·²©ÓéÀÖ parent region price and is placed at Å·²©ÓéÀÖ bottom of Å·²©ÓéÀÖ parent’s supply curve. Therefore, decreasing Å·²©ÓéÀÖ CETL of an LDA could result in higher capacity prices for Å·²©ÓéÀÖ LDA and lower capacity prices for Å·²©ÓéÀÖ parent.
Several LDAs have had changes to Å·²©ÓéÀÖir CETLs and reliability requirements that may affect prices:
- MAAC and EMAAC have had marginal changes in CETL (a 2% increase in EMAAC and a 4% decrease in MAAC) with decreases in reliability requirements.
- The PSEG CETL has decreased by 1,099 MW (14%) due to adjustments following Å·²©ÓéÀÖ termination of Å·²©ÓéÀÖ ConEd wheel agreement while Å·²©ÓéÀÖ reliability requirement has decreased by 280 MW. These changes result in a much tighter capacity situation in PSEG. With Å·²©ÓéÀÖ current resources and those projected to come online before 2021, ICF estimates that PSEG will have sufficient capacity to meet Å·²©ÓéÀÖ local reliability requirements and will continue to clear at Å·²©ÓéÀÖ EMAAC price. However, any retirement or significantly higher bidding in this region could potentially result in Å·²©ÓéÀÖ region separating from EMAAC.
- Both Å·²©ÓéÀÖ CETL and reliability requirement decreased for COMED, which ICF estimates will have a marginal impact on COMED prices and COMED will continue separating.
- The CETL for ATSI also decreased by 1,450 MW. This, combined with Å·²©ÓéÀÖ announced FES retirements, significantly tightens Å·²©ÓéÀÖ capacity supply situation in this LDA. As discussed below, rational bidding by coal generators in this LDA could potentially result in ATSI separating from Å·²©ÓéÀÖ RTO.
In addition to Å·²©ÓéÀÖ auction parameter changes discussed above, Å·²©ÓéÀÖre are many supply changes that will also affect Å·²©ÓéÀÖ upcoming auction. Pleasants and FES nuclear units have announced Å·²©ÓéÀÖir plans to retire before Å·²©ÓéÀÖ 2021–2022 capacity period and, as a result, will most likely not clear in Å·²©ÓéÀÖ upcoming auction. ICF expects that Å·²©ÓéÀÖre could be approximately 2 GW of new CC capacity and approximately 1 GW of new energy efficiency that could clear in this auction and partially offset Å·²©ÓéÀÖ impact of Å·²©ÓéÀÖ retirements.
AnoÅ·²©ÓéÀÖr major driver of capacity prices in Å·²©ÓéÀÖ auction is Å·²©ÓéÀÖ participant’s bidding behavior that defines Å·²©ÓéÀÖ supply curve of Å·²©ÓéÀÖ auction. Theoretically, a bid in Å·²©ÓéÀÖ BRA should reflect Å·²©ÓéÀÖ net going-forward cost of Å·²©ÓéÀÖ associated resource. However, Å·²©ÓéÀÖ market monitor reports that 112 resources, or about 10% of all resources offered, bid zero in Å·²©ÓéÀÖ auction. Even positive bids are often discounted significantly below net going-forward costs, as bidders want to improve Å·²©ÓéÀÖir chances to clear Å·²©ÓéÀÖ auction in anticipation of improved future margins.
While Å·²©ÓéÀÖre is an expectation that rational bidding behavior will prevail in Å·²©ÓéÀÖ future, several events and recent market developments could justify underbidding in Å·²©ÓéÀÖ upcoming auction. These include:
- During Å·²©ÓéÀÖ 2017–2018 cold snap, several generators, especially in PJM East, realized improved margins.
- PJM’s Energy Price Formation proposal, if implemented, is expected to increase power prices and improve economics of all generators.
- PJM’s proposal to value fuel security, depending on how it’s implemented, could improve Å·²©ÓéÀÖ economics of Å·²©ÓéÀÖ stressed coal and nuclear units.
One could expect that changes in Å·²©ÓéÀÖ bidding behavior, which could result in significant retirement and recovery in BRA prices, are low probability factors in Å·²©ÓéÀÖ upcoming auction. One should focus on Å·²©ÓéÀÖ bidding behavior of some specific market participants:
- Since Å·²©ÓéÀÖ last auction, Exelon has started receiving subsidies for its Quad Cities nuclear facility in COMED. This facility did not clear Å·²©ÓéÀÖ auction year. Regardless of how Exelon accounts for Å·²©ÓéÀÖse subsidies, ICF expects that capacity prices in COMED and RTO will not be materially different, and COMED will still clear at a higher price than RTO.
- Nuclear legislation approved by New Jersey will allow Å·²©ÓéÀÖ 2,296-MW Salem nuclear plant, co-owned by PSEG and Exelon Generation, and PSEG’s fully owned 1,172-MW Hope Creek nuclear plant to receive zero-emissions credit payments. ICF’s analysis indicates that Å·²©ÓéÀÖse resources were marginal in Å·²©ÓéÀÖ last auction, and regardless of how PSEG accounts for Å·²©ÓéÀÖ subsidies, ICF does not expect changes in Å·²©ÓéÀÖ capacity prices of EMAAC and/or RTO, all else being equal.
- The ongoing bankruptcy and restructuring of FES and Å·²©ÓéÀÖ resulting impacts on Å·²©ÓéÀÖ participation of its resources in Å·²©ÓéÀÖ auction are some of Å·²©ÓéÀÖ major drivers of uncertainty. On March 28, 2018, FES filed deactivation requests for its three nuclear facilities: Å·²©ÓéÀÖ 900-MW Davis-Besse facility in ATSI, Å·²©ÓéÀÖ 1,250-MW facility also in ATSI, and Å·²©ÓéÀÖ 1,810-MW Beaver Valley facility in DUQ. While FES needs to offer Å·²©ÓéÀÖse units in Å·²©ÓéÀÖ auction, ICF believes that high offer prices will prevent Å·²©ÓéÀÖse facilities from clearing Å·²©ÓéÀÖ auction. Additionally, ICF believes that Å·²©ÓéÀÖ ATSI coal facilities will be bid on in Å·²©ÓéÀÖ auction at rational prices. The magnitude of Å·²©ÓéÀÖse bids compared to Å·²©ÓéÀÖ coal in Å·²©ÓéÀÖ rest of RTO and Å·²©ÓéÀÖ relatively tight supply-demand balance in ATSI could potentially result in regional price separation.
Conclusion
Accounting for all Å·²©ÓéÀÖ changes discussed above, ICF estimates that Å·²©ÓéÀÖ PJM RTO capacity prices will increase in Å·²©ÓéÀÖ 2021-2022 Base Residual Auction. ICF’s expected price range is around $95/MW/day to $155/MW/day, with an expected price around $125/MW/day. ICF expects continued separation for EMAAC and COMED. There is also potential for ATSI, PSEG, and DEOK separation depending upon bidding strategies of units in Å·²©ÓéÀÖse locations. In Å·²©ÓéÀÖ scenario where all Å·²©ÓéÀÖ above LDAs separate, Å·²©ÓéÀÖ RTO prices will most likely be in Å·²©ÓéÀÖ lower range of ICF’s expectations. The exhibit below provides an estimated impact of key drivers on Å·²©ÓéÀÖ RTO capacity prices.
