Maven Solutions, a decision-intelligence practice, argues that PJM's current tariff posture on large-load interconnection is inadequate regarding ratepayer protection and financial surety. They recommend that the Commission require PJM to submit specific tariff revisions to improve transparency, cost-causation methodologies, and reliability-hold-harmless mechanisms.

The Global Capacity Alliance (GCA), a nonprofit association, requests to intervene in the proceedings and urges the Commission to incorporate "Front-of-the-Meter (FTM) Netting" frameworks into RTO/ISO compliance strategies. They argue that FTM-Netting allows large loads (like data centers) to privately fund and manage capacity while maintaining grid visibility and reliability.

Lisa Melton, filing as L.M. Marlowe, is a private citizen and independent researcher who supports the Commission's Show Cause Orders by providing technical specifications for grid reliability. She argues for a "Frequency-Response Absorption Standard" and a "Coupling-Discrimination Protocol" to ensure that large-load integration does not compromise system stability or unfairly shift costs to ratepayers.

New Era Energy & Digital Inc., a data center developer, supports the Commission's action to reform PJM's tariff rules regarding large loads. They argue that PJM should adopt a "Maximum Net Withdrawal" framework for co-located generation and include fast-track processes for safe supply additions like uprates and reactivations in its resource-adequacy report.

Lisa Melton, an independent researcher and private citizen, supports the Commission's efforts to address the reliability and cost-allocation challenges posed by large computational loads. She proposes a specific "boundary-verification" framework to ensure grid stability and cost-causation without requiring access to proprietary internal data.
