When it comes to managing congestion risk in energy markets, PJM and CAISO take distinct approaches. PJM uses Financial Transmission Rights (FTRs), while CAISO employs Congestion Revenue Rights (CRRs). Both mechanisms aim to protect market participants from the financial impacts of transmission congestion, but the processes and structures behind these rights differ significantly.
In this blog post, we’ll explore how PJM allocates FTRs through its auction and allocation processes, how CAISO handles CRRs, and the key differences in how these rights are used to hedge congestion risk. By the end, you’ll have a clear understanding of how these markets operate and how their approaches to congestion management compare.

How PJM allocates financial transmission rights (FTRs)
PJM’s Financial Transmission Rights (FTRs) are financial instruments designed to hedge against transmission congestion costs in the Day-ahead Market. These rights don’t represent physical delivery of power but instead entitle the holder to receive compensation for congestion charges between a specified point of receipt and point of delivery.
The allocation process for FTRs in PJM begins with Auction Revenue Rights (ARRs). ARRs are allocated to transmission customers based on their historical usage of the grid. These rights give customers the option to either convert ARRs into FTRs or receive a share of the revenue generated from FTR auctions.
PJM conducts three types of FTR auctions: the Long-term FTR Auction, the Annual FTR Auction, and the Monthly FTR Auction. Each serves a specific purpose:
- Long-term FTR Auction: Covers multiple planning years and allows participants to secure rights for extended periods.
- Annual FTR Auction: Allocates FTRs for a single planning year.
- Monthly FTR Auction: Offers FTRs for shorter-term needs, typically one month.
The auction process ensures that all FTRs awarded are simultaneously feasible, meaning they don’t exceed the transmission system’s capacity. This feasibility is critical to maintaining the financial integrity of the market.

How CAISO allocates congestion revenue rights (CRRs)
CAISO’s Congestion Revenue Rights (CRRs) serve a similar purpose to PJM’s FTRs but operate under a different framework. CRRs allow market participants to hedge against congestion costs in CAISO’s Day-ahead Market. Like FTRs, CRRs are financial instruments and don’t involve the physical delivery of electricity.
CAISO allocates CRRs through an annual allocation process and an auction process. The annual allocation prioritizes load-serving entities (LSEs), ensuring they can secure CRRs to hedge congestion costs for their customers. After the allocation, any remaining CRRs are made available through auctions, where market participants can bid for them.
One key difference in CAISO’s approach is the emphasis on ensuring that CRRs align with the physical capabilities of the grid. This alignment minimizes the risk of over-allocation and ensures that CRRs remain a reliable tool for hedging congestion costs.

Key differences between PJM’s FTRs and CAISO’s CRRs
While both FTRs and CRRs aim to mitigate congestion risk, their allocation processes and market structures highlight some key differences:
- Allocation process: PJM uses ARRs as a precursor to FTRs, giving participants flexibility in how they manage congestion risk. CAISO, on the other hand, directly allocates CRRs to LSEs before opening them up for auction.
- Auction structure: PJM offers multiple auction types (long-term, annual, and monthly), while CAISO focuses on annual allocations and subsequent auctions.
- Grid alignment: CAISO places a stronger emphasis on ensuring CRRs align with the physical grid’s capabilities, reducing the risk of over-allocation.
These differences reflect the unique needs and operational structures of each market, offering tailored solutions for managing congestion risk.
Why understanding these differences matters
For market participants, understanding how FTRs and CRRs work is essential for effective risk management. PJM’s multi-layered approach provides flexibility and long-term planning options, while CAISO’s focus on grid alignment ensures reliability and minimizes financial risk. By grasping these distinctions, participants can make informed decisions that align with their operational and financial goals.
Whether you’re navigating PJM’s FTR auctions or CAISO’s CRR allocations, knowing the nuances of each market can help you hedge congestion risk more effectively and optimize your participation in these dynamic energy markets.
