Introduction
The Federal Energy Regulatory Commission (FERC) published a combined notice of filings on March 13, 2026, in the Federal Register. This document lists submissions received by the agency between February 25 and March 10, 2026, covering areas such as accounting requests, exempt wholesale generator certifications, electric rate changes, securities applications, and qualifying facility registrations. Issued under the Department of Energy, the notice informs the public of these regulatory actions and sets deadlines for comments or interventions, typically by late March 2026. This routine publication underscores FERC's role in overseeing interstate electricity transmission and wholesale sales, ensuring transparency in a sector vital to national energy security and economic stability. By highlighting these filings, the notice facilitates public participation in decisions that could influence energy prices, renewable integration, and infrastructure development.
Overview of Filing Categories
FERC's combined notice organizes filings into distinct categories, each governed by specific sections of the Federal Power Act and related regulations. Accounting requests, for instance, involve financial reporting for asset transactions, as seen in Arizona Public Service Company's submission regarding its purchase of interests in the Palo Verde Nuclear Generating Station Unit 2. Exempt wholesale generator (EWG) filings allow entities to self-certify status under the Public Utility Holding Company Act of 2005, exempting them from certain regulations if they sell power exclusively at wholesale. The notice includes EWG certifications for wind and solar projects, reflecting a push toward clean energy.
Electric rate filings, submitted under Section 205 of the Federal Power Act, propose changes to tariffs or agreements that affect wholesale electricity rates. These often involve utilities like Duke Energy or PJM Interconnection adjusting terms for interconnection or reimbursement. Electric securities filings seek authorization to issue debt or equity, enabling companies to fund operations or expansions. Finally, qualifying facility filings under the Public Utility Regulatory Policies Act of 1978 certify small power producers or cogenerators for favorable rate treatment.
This structure ensures systematic review, with public access via FERC's eLibrary system for detailed examination.
Key Players and Specific Filings
Several prominent entities appear in the notice, including major utilities and renewable developers. Arizona Public Service Company filed accounting entries for acquiring stakes in Palo Verde Unit 2, a nuclear facility in Arizona co-owned by multiple utilities. This transaction, docketed as AC26-30-000, finalizes financial records for the purchase, potentially impacting cost recovery in rates.
In the EWG category, Panther Grove Wind, LLC and Panther Grove 2 LLC submitted self-certifications for wind projects, while Big Muddy Solar Project, LLC did the same for a solar initiative. These filings, under dockets EG26-174-000 through EG26-176-000, indicate new renewable capacity entering wholesale markets, aligned with federal incentives like those in the Inflation Reduction Act of 2022.
Electric rate filings feature responses to prior FERC inquiries and new agreements. For example, High Prairie Wind Farm II, LLC addressed a deficiency letter in ER10-2405-016, providing additional details on its market-based rate authority. Duke Energy entities filed a compliance update in ER25-2640-001 to incorporate standards from FERC Order No. 676-K, which updates technical requirements for electronic data interchange in energy transactions.
Other notable entries include PJM Interconnection's generator interconnection agreements (GIAs), such as in ER26-1681-000, facilitating new projects' grid access. AEP Texas Inc. amended an interconnection deal for a battery energy storage system in ER26-1682-000, highlighting the growing role of storage in grid reliability. Kincaid Generation, L.L.C. petitioned for a waiver in ER26-1686-000 related to PJM's must-offer requirement for capacity auctions, citing procedural deadlines for the 2028/2029 delivery year.
The securities filing from NextEra Energy Transmission MidAtlantic, Inc. (ES26-31-000) requests authority under Section 204 to issue securities, likely to support transmission infrastructure. A qualifying facility filing from DuPont Specialty Products USA, LLC (QF26-583-000) certifies a cogeneration plant, enabling it to sell excess power.
Background and Legal Context
These filings occur against a backdrop of evolving energy policy. FERC, established by the Department of Energy Organization Act of 1977, regulates wholesale electricity markets to promote competition and reliability. Precedents like FERC Order No. 888 (1996), which mandated open access to transmission, underpin many rate filings by requiring non-discriminatory terms.
Renewable-focused EWGs tie into the Energy Policy Act of 2005, which streamlined certifications to encourage investment. For nuclear assets like Palo Verde, accounting follows Uniform System of Accounts prescribed in 18 CFR Part 101, ensuring transparent cost allocation. Waiver requests, such as Kincaid's, reference PJM's tariff under FERC-approved rules, where exceptions to must-offer obligations might be granted for retiring units, as in past cases like the 2018 waiver for Avon Lake Power Plant.
Political forces include the Biden administration's clean energy goals, though state-level policies vary. Perspectives differ: utilities emphasize grid stability, while environmental groups advocate faster renewable adoption. Consumer advocates scrutinize rate filings for potential cost increases, balancing innovation with affordability.
Implications and Perspectives
Short-term, these filings could expedite project approvals, with comment periods allowing stakeholders to influence outcomes. For instance, solar and wind certifications may accelerate clean energy deployment, reducing emissions but raising integration challenges for grid operators.
Long-term implications involve market dynamics. Increased renewables could lower wholesale prices through competition, yet nuclear transactions like Arizona Public Service's maintain baseload power amid debates over nuclear's role in decarbonization. Waiver petitions highlight capacity market tensions, where retirements affect reliability, as seen in PJM's 2022 auction shortfalls.
Different views emerge: industry players see these as routine business, while regulators focus on compliance. Critics argue FERC's processes favor incumbents, potentially slowing innovation, whereas supporters note the framework's success in expanding renewables, with U.S. wind and solar capacity doubling since 2010 per Energy Information Administration data.
Conclusion
In summary, FERC's March 13, 2026, notice captures a snapshot of regulatory activity driving the energy sector's evolution. Key takeaways include the integration of renewables, updates to interconnection agreements, and financial maneuvers by major utilities.
