January 2025 ISSUE

Markets+ Friends -

SPP presents this monthly newsletter compiling timely, useful information related to Markets+ development. Have questions or comments? Email marketsplus@spp.org. We’d love to hear from you.

FERC Markets+ Tariff decision

SPP is extending the Dec. 16, 2024 target date for executed phase two agreements due to a later-than-anticipated response from the Federal Energy Regulatory Commission (FERC). While this delay is unfortunate, it does not signal any issue with the approval of the Markets+ tariff. FERC is carefully reviewing the tariff filing, and we fully respect their thorough process.


Any significant delay in FERC’s response could affect the overall implementation timeline. However, the impact will depend on the timing of FERC’s decision. We are closely monitoring the situation and will provide stakeholders with updates as soon as possible.


In the meantime, SPP staff and Markets+ participants will continue to refine the detailed protocols necessary for the market’s administration.
