What to Know About ISO/RTO Annual Certification Requirements

Explore an overview of the annual certification requirements in each of the organized wholesale electricity markets operated by the independent system operators and regional transmission operators (ISO/RTO) markets in the US. Each year market participants must certify ongoing compliance through an officer’s certification that states they meet requirements to participate in the market.

This certification is provided to the ISO/RTOs upon entry into the market(s), then updated annually on 30 April. As a participant in these markets, you will need to certify that you meet:

  1. Risk management and operational requirements,
  2. Training requirements,
  3. Minimum capitalization requirements, and
  4. Minimum participation requirements.


The officer certification requirements arise from several sources and have undergone a series of changes over the years. In 2010, the Federal Energy Regulatory Commission (FERC) issued Order No. 741, 1 which required the ISO/RTOs to improve their credit and risk management functions. Order No. 741 set forth the requirement for annual officer certification, along with minimum participation and capitalization requirements.

Shortly thereafter, in 2013, the Commodity Futures Trading Commission (CFTC) exempted certain products in the ISO/RTO markets that could be considered derivatives from its jurisdiction under the Commodity Exchange Act on the grounds that FERC or the Public Utility Commission of Texas (PUCT) was regulating those products and markets. 2 In particular, the CFTC noted the existence of minimum participation and minimum capitalization requirements as evidence of FERC’s market oversight.

Following the default by GreenHat Energy LLC (GreenHat) in the markets operated by PJM Interconnection, L.L.C. (PJM) in 2018, most of the ISO/RTOs revisited and strengthened their credit and risk requirements. In particular, this involved the addition of Know Your Customer (KYC) elements to the initial market entry review and annual officer certification as well as heightened review of risk policies.

Also following the GreenHat default, many ISO/RTOs created credit committees to review risk and credit issues on an ongoing basis. PJM created the Risk Management Committee in 2021, which meets monthly to consider a range of risk and credit issues. The Southwest Power Pool, Inc. (SPP) has had a long-standing Credit Policies Working Group. The Midcontinent Independent System Operator, Inc. (MISO) created the Credit Practice Enhancement Task Team that began meeting in September 2023. The California Independent System Operator (CAISO) created a limited stakeholder process to consider some discrete changes to its tariff regarding minimum participation through the Billing, Payment and Credit Enhancements initiative. Market participants must remain aware and up-to-date on these committees’ proposals.

Risk Management and Operational Requirements

One of the ISO/RTOs’ primary concerns is ensuring that market participants have strong risk management practices. They expect that market participants will have written risk management policies, procedures, and controls, all approved by an independent risk management function. These policies, procedures, and controls should include, but are not limited to, credit risks, liquidity risks, and market risks.

ISO/RTOs also expect that market participants have appropriate organizational structures with clearly defined roles and responsibilities that clearly segregate trading and risk management functions. This ensures that the individuals enforcing the risk management policies, and who are expected to have oversight responsibilities, are not those executing trades.

In addition to these requirements, ISO/RTOs expect that market participants in Financial Transmission Rights (FTR) auctions have at least weekly measurement of FTR mark-to-market (or mark-to-auction) exposure and FTR risk calculations.

Training Requirements

ISO/RTOs and FERC expect that when transacting in the ISO/RTO markets, employees or contractors have adequate training or expertise relative to their authority in that ISO/RTO. In the course of an investigation, FERC’s Office of Enforcement sometimes requests a party to list what training traders have attended.

PJM’s officer certification form requires that traders have appropriate training, with “appropriate” defined as “training that is (i) comparable to generally accepted practices in the energy trading industry, and (ii) commensurate and proportional in sophistication, scope and frequency to the volume of transactions and the nature and extent of the risk taken by the participant.” This fairly broad definition gives market participants a significant degree of latitude in determining appropriate training requirements for their traders.

Many ISO/RTOs provide a variety of optional training courses on their markets, available on their websites or in person. Only two ISO/RTOs specify required courses for traders engaging in their markets:

  • NYISO: Each employee and agent that bids on virtual transactions or Transmission Congestion Contracts (TCC) on behalf of a customer shall successfully complete the designated ISO-administered online training course on virtual transactions and/or TCCs one time, as applicable; provided, however, this requirement does not apply to a transmission owner as a result of its receipt of net auction revenue.
  • CAISO: Congestion Revenue Rights (CRR) holders and candidate CRR holders must attend a training class at least once before participating in the CRR allocations or CRR auctions. The CAISO may update training requirements annually or on an as-needed basis. Unless granted a waiver by the CAISO, candidate CRR holders and CRR holders shall at all times have in their employment a person, or have obtained the services of a third party or consultant, who has attended the CAISO’s CRR training class and shall notify the CAISO as soon as practicable of a change in such status.

We strongly recommend encouraging traders to take any available and relevant training courses offered by an ISO/RTO.

Minimum Capitalization Requirements

All ISO/RTO markets, including the Electric Reliability Council of Texas (ERCOT), have established minimum requirements to participate in the markets. These requirements arise out of the CFTC’s requirements as part of its exemption of ISO/RTO transactions from its jurisdiction under the CEA.

Each ISO/RTO requires audited financial statements to demonstrate compliance with these requirements, though some ISO/RTOs permit alternatives when audited financials are not available. Each market participant must demonstrate that they meet the following criteria, both initially when entering the market and on a continuing basis:

  1. “Appropriate person” as defined by the CEA, of $1 million net worth or $5 million assets, or
  2. “Eligible contract participant” as defined by the CEA (higher than the appropriate person threshold, so a less valuable and more restrictive option), or
  3. Physical exemption: participate in generation, transmission, or distribution of electric energy. This criteria includes Load Serving Entities.

Many ISO/RTOs permit a market participant to post a letter of credit, corporate guaranty, or cash if a market participant is unable to meet the above criteria.

Minimum Participation Requirements (FERC, PUCT)

In addition to the minimum capitalization requirements set forth in the CEA, each ISO/RTO requires a further showing of minimum participation requirements under requirements set forth by FERC or the PUCT, as applicable. Some of these requirements match the minimum capitalization requirements, but some differ slightly. Further, a market participant posting a letter of credit or corporate guaranty to meet minimum capitalization requirements may be required to post additional funds to meet the minimum participation requirements. In the below chart, we use the acronym MPR for “market participation requirement” and TNW for “tangible net worth.”

Market FTR
Non-FTR MPR Audited Financials? Posting
Tariff Location
PJM $1 million TNW or $10 million assets $500,000 TNW or $5 million assets Yes Corporate guaranty of at least $500,000 or unlimited Tariff Attachment Q
MISO $1 million TNW or $10 million assets $500,000 TNW or $5 million assets Yes Corporate guaranty of $500,000 for non-FTR or $1 million for FTR Tariff Attachment L
ISO-NE $1 million TNW or $10 million assets N/A Yes May supplement with additional financial assurance ISO-NE Financial Assurance Policy
NYISO $1 million TNW or $10 million assets N/A Yes $200,000 for non-FTR or $500,000 for FTR MST Attachment K
SPP $10 million TNW or $20 million assets $1 million TNW or $10 million assets Yes $200,000 for non-FTR or $2 million for FTR Tariff Attachment X
CAISO $1 million TNW or $10 million assets N/A Yes $500,000 for a new market participant; $100,000 for existing.1 Tariff Section 12
ERCOT $1 million TNW or $10 million assets $500,000 TNW or $5 million assets Yes Irrevocable letter of credit Protocols Section 16

1 Note that CAISO is in the process of changing this requirement, to remove the option for $100,00 for existing market participants. 

Note that several of the ISO/RTOs have made changes to their minimum requirements over the past two years in response to the GreenHat default referenced above as well as other factors, so continued monitoring of requirements is necessary.


As you prepare to execute an annual officer certification on behalf of your company, closely review the requirements and certifications you are making to ensure there have been no changes or otherwise reportable events.
