The Federal Energy Regulatory Commission is where many of the decisions shaping America’s transmission system get made — how the grid is planned, how costs are allocated, and how quickly new capacity can come online. ACEG monitors these proceedings closely and files comments in the ones that matter most for transmission expansion.
This page tracks the FERC dockets we’re following. Each entry lays out the proceeding’s activity in chronological order, with links to key filings and orders, including ACEG’s own.

On February 20, 2025, FERC instituted a show cause proceeding under section 206 of the Federal Power Act, directing PJM and its transmission owners to explain why PJM's tariff remains just and reasonable without specific provisions for co-location arrangements, or propose changes if it is found unjust or unduly discriminatory.
This proceeding was consolidated with the November 2024 technical conference and the Constellation complaint on fully isolated co-located loads.
On April 24, 2025, ACEG submitted comments.
On December 18, 2025, FERC issued a draft Order stating that PJM's Tariff was unjust and unreasonable, finding that there was insufficient clarity or consistency in the rates, terms, and conditions of services that apply to generators serving co-located load and eligible customers taking transmission service on behalf of co-located loads.

On December 19, 2024, the Industrial Energy Consumers of America, et al., filed a complaint challenging provisions in tariffs of FERC-jurisdictional public utility transmission providers, including RTOs/ISOs and independent transmission owners, that the complaint claims allow individual transmission owners to plan transmission facilities at 100 kV and above without ensuring these plans are the most efficient or cost-effective for the grid or consumers.
