In this post, we’re diving into the Base Residual Auction (BRA) results conducted by PJM on July 17, 2024. These results cover the capacity delivery year from June 1, 2025, to May 31, 2026, and they have led to the highest capacity rate increases in history—an event that necessitates a deep dive into what this means for your business.
What is the Base Residual Auction (BRA)?
The BRA is a vital mechanism through which PJM procures resource commitments to satisfy the region’s unforced capacity obligation for each delivery year. The costs for these commitments are allocated to load-serving entities (LSEs), such as NRG, via a Locational Reliability Charge. These funds are then paid to power supply resources across the grid based on their performance.
The BRA ensures that there are adequate electricity supplies to meet future energy demands. The auction settles at a single price, determined by the most expensive resource needed to meet capacity requirements.
Key Points about the BRA
- Final capacity rates for any delivery year typically align closely with the BRA settlement rate for each load-serving area (LDA). Therefore, BRA results are critical for predicting rates for that specific delivery year.
- Settlement rates at the regional transmission organization (RTO) level establish a base rate used for calculating rates across different LDAs and transmission zones. This year, all major LDAs settled at the same price of $269.92 per MW-day.
The Impact of the 2025/26 BRA Results
The results from the 2025/26 BRA are staggering. Most areas in the RTO experienced rates more than nine times higher than the previous year, reflecting an increase of $241/MW-day. Specific areas saw even more dramatic increases:
- Dominion, VA experienced a rise of over 15x higher, with an increase of $415.34/MW-day.
- Baltimore Gas & Electric settled more than 6x higher, with a rise of $393.35/MW-day.
- Interestingly, the Delmarva area experienced a decrease of $156.25/MW-day.
What Led to These Increases?
According to PJM, these significant increases can be attributed to:
- Decreased Supply Offers: Fewer resources were offered in the auction primarily due to generator retirements.
- Increased Projected Peak Load: Growing demand for electricity resulted in a need for more capacity resources.
- Market Reforms: The implementation of FERC-approved reforms improved how reliability risks are modeled, particularly for extreme weather events.
What is a Capacity Tag, and How Is It Assigned?
A capacity tag represents your business’s expected energy usage during peak demand periods. Essentially, it is calculated based on historical usage and establishes your capacity obligation. The assignment process typically involves:
- Analyzing your peak load history.
- Reviewing your energy usage patterns and the types of equipment used.
- Adjustments based on market conditions and overall energy demand forecasts.
Understanding Cost Implications
The recent BRA results will undoubtedly impact your utility rates. Capacity costs are calculated by multiplying the capacity rate by your peak load contribution. While you can’t control settling rates, there are opportunities to manage your peak load contribution through effective load management strategies—a service that Brilliant Source Energy offers.
Cost Example from the 2025/26 BRA
To illustrate the impact on business expenses, consider a business with a 1 MW capacity tag in one of the RTO areas:
- Monthly Cost:
( $269.92 , {MW-day} 1 , {MW} x31 , {days} = $8,368 , {monthly} )
Compared to just $897 monthly using the 2024/25 delivery period rate. - Annual Cost:
( $269.92 , {/MW-day} 1 , {MW} 365 , {days} = $98,521 , {annually} )
Compared to $10,556 with the previous year’s rates.
How to Manage Demand Effectively
With these new dynamics in the market, managing demand is key. Here are strategies to consider:
- Energy Efficiency Initiatives: Upgrade to energy-efficient appliances and engage in practices that reduce demand during peak hours.
- Participation in Demand Response Programs: Activate load reduction during peak periods in exchange for financial incentives.
- Time-of-Use Pricing Awareness: Shift high-energy consumption activities to off-peak hours when costs are lower.
- Load Management Systems: Utilize technology to automatically balance energy loads and avoid spikes that can lead to higher charges.
Your Next Steps
The BRA results signal a paradigm shift in the energy market, presenting challenges but also opportunities for businesses. Understanding the intricacies of demand, capacity tags, and their impact on your costs is crucial for navigating this evolving landscape.
