Re: CFTC Regulation 40.2(a) Certification: Notification of Product Offered for Trading on 

Nodal Exchange, LLC – ERCOT HB_SOUTH Monthly Real Time HE 18-22 (5x) Power Contract

Dear Mr. Kirkpatrick:

Nodal Exchange, LLC (“Nodal Exchange” or “Exchange”) is notifying the Commodity Futures Trading 

Commission (“CFTC” or “Commission”) that pursuant to Commission Regulation 40.2(a), the 

Exchange is self-certifying the listing of 23 new power futures contracts for trading on Nodal 

Exchange beginning on or after December 1, 2023. The contract specifications describing these new 

Exchange futures contracts are attached to this letter as Exhibit A, to be added to the Nodal Exchange 

Rulebook Appendix A – Contract Specifications. The deliverable supply analysis has been segregated 

as Exhibit B, for which confidential treatment is requested. The reporting levels, accountability 

levels, and position limits for these contracts are attached to this letter as Exhibit C, which will be 

added to the Nodal Exchange Rulebook Appendix C - Reporting Levels, Accountability Levels and 

Position Limits.

Exchange management has assessed the Exchange’s contracts’ compliance with applicable provisions 

of the Commodity Exchange Act (“Act”), including the Commissions Regulations thereunder and the 

Core Principles. Regulatory compliance of Nodal Exchange’s futures and options contracts is mostly 

addressed in the Nodal Exchange Rulebook, concisely explained as follows:

Core Principle 2 - Compliance with the Rules: Trading in the Exchange’s contracts will be subject to 

the Nodal Exchange Rulebook in Section IV, describing trading procedures, and Section VI, which 

establishes trading codes of conduct, sound trading practices, and identifies prohibited trading 

behavior and abuses. In addition, trading behavior and activity will be subject to extensive 

monitoring and surveillance by the Exchange’s Division of Market Administration and Surveillance. 

The Exchange’s Compliance Department has the authority to address disciplinary matters through 

investigation and enforcement procedures in accordance with Section VII of the Exchange Rulebook.

Core Principle 3 - Contracts not Readily Susceptible to Manipulation: Nodal Exchange’s new 

contracts settle to power prices published by PJM, CAISO and ERCOT. The PJM and CAISO markets 

are regulated by the Federal Energy Regulatory Commission (“FERC”) and the ERCOT markets are 

regulated by the Public Utility Commission of Texas (“PUCT”). The day ahead and real time markets

that generate the prices to which the Exchange contracts settle are directly related to the physical 

generation, and demand for, electricity as well as the physical capacity constraints of the grid. A 

description of the underlying cash markets and deliverable supply analysis for the Exchange’s new 

contracts is provided in attached Exhibit B, which demonstrates compliance that the Exchange’s new 

contracts are not readily susceptible to manipulation.

Core Principle 4 - Prevention of Market Disruption: Trading in the Exchange’s contracts will be 

subject to the Nodal Exchange Rulebook Section VI, which prohibits disruptive trading behavior and 

manipulation, subject to monitoring and surveillance by the Exchange’s Division of Market 

Administration and Surveillance.

Core Principle 5 - Position Limitations or Accountability: The spot-month speculative position limits 

for the Exchange’s contracts are set at less than 25% of the deliverable supply in the respective 

underlying market. In addition, the Exchange monitors and enforces position accountability rules for 

individual single-month and all-months combined, which are also within 25% of deliverable supply. 

The new contract reporting levels, accountability levels and position limits are provided in attached 

Exhibit C, to be added to the Nodal Exchange Rulebook Appendix C – Reporting Levels, Position 

Accountability Levels and Position Limits.

Core Principle 7 - Availability of General Information: The Exchange will post general information, 

including the contract specifications for the new contracts, Exchange fees, and the Nodal Exchange 

Rulebook, on the Exchange’s website: www.nodalexchange.com.

Core Principle 8 - Daily publication of Trading Information: The Exchange will publish daily 

information on settlement prices, volume, open interest and opening and closing ranges for the 

Exchange’s actively traded contracts on its website.

Core Principle 9 - Execution of Transactions: The Exchange’s new contracts will be available on the 

Exchange’s electronic trading screen that is a central limit order book (“CLOB”). The CLOB provides 

the market with the ability to execute the Exchange’s contracts from the interaction of multiple bids 

and multiple offers within a predetermined, nondiscretionary automated trade matching and 

execution algorithm. 

Core Principle 10 - Trade Information: The CLOB will maintain all information with respect to each 

order and each consummated trade, as well as all other information relating to the trade environment 

that determines the matching and clearing of trades. As such, any order submitted to the CLOB can 

be tracked from the time it is entered into the system until the time that it is matched, canceled or 

otherwise removed.

Core Principle 11 - Financial Integrity of Transactions: The Exchange has entered into a clearing 

arrangement with Nodal Clear, a derivatives clearing organization subject to Part 39 of the 

Commission Regulations. The new contracts executed on the CLOB or as a block trade will be subject 

to the Exchange Rulebook provisions for submission to Nodal Clear for clearing as described in 

Section V. 

Core Principle 12 - Protection of Markets and Market Participants: Section VI of the Nodal Exchange 

Rulebook protects the market and market participants from abusive, disruptive, fraudulent,
Page 3 of 3

23-036.10

noncompetitive and unfair conduct and trade practices. The new contracts are subject to these rules 

that apply to all transactions in the Exchange’s contracts.

Core Principle 13 - Disciplinary Procedures: Section VII of the Nodal Exchange Rulebook describes 

the disciplinary procedures of the Exchange that authorize the Exchange to discipline, suspend, or 

expel anyone on the Exchange that violates these rules. 

Core Principle 14 - Dispute Resolution: Section VIII of the Nodal Exchange Rulebook establishes rules 

concerning alternative dispute resolution, which provide for the resolution of disputes between or 

among Exchange users through the NFA arbitration program. Under Section VIII, arbitration is 

available for all disputes, controversies or claims among all Exchange users relating to Exchange 

activities. 

Pursuant to Section 5c(c) of the Act and the Commission’s Regulation 40.2(a), the Exchange certifies 

that the Exchange’s new futures contracts to be listed comply with the Act and the Commission’s 

Regulations thereunder.

Nodal Exchange certifies that this submission has been concurrently posted on the Nodal Exchange 

website at www.nodalexchange.com.

If you have any question or need additional information regarding the above, please contact the 

undersigned at 703-962-9853 or markotic@nodalexchange.com or Ken McCracken, Chief 

Regulatory Officer & General Counsel at 703-962-9835 or mccracken@nodalexchange.com.
