FERC Faces April Deadline on Data Center Interconnection Rules
Federal regulators must act by April 30 on first-ever standards for connecting large electrical loads to the interstate transmission system, a move driven by surging demand from AI-powered data centers.
The Federal Energy Regulatory Commission is approaching an April 30, 2026, deadline to take final action on a landmark rulemaking that would establish the first federal standards for connecting large electrical loads — including data centers exceeding 20 megawatts — to the interstate transmission system. The proceeding, initiated under Docket No. RM26-4-000, responds to a directive issued by U.S. Secretary of Energy Chris Wright in October 2025 under Section 403 of the Department of Energy Organization Act, and represents one of the most significant regulatory actions affecting the intersection of energy law and technology infrastructure in recent years.
The rulemaking has drawn intense attention from utilities, grid operators, data center developers, and energy attorneys, as the outcome will shape how the nation’s power grid accommodates a historic surge in electricity demand driven by artificial intelligence workloads and large-scale computing facilities.
The regulatory initiative stems from an unprecedented acceleration in U.S. electricity demand growth. Data centers drove a 22 percent increase in power demand in 2025, with projections suggesting that figure could triple by 2030. The North American Electric Reliability Corporation issued a Level 2 Alert in September 2025 through its Large Load Task Force, highlighting grid disturbances, inadequate modeling, insufficient technical interconnection requirements, and a lack of operating protocols to handle the influx of large loads.
FERC Chairman Laura Swett has identified connecting data centers to the grid as her top priority, alongside the agency’s core mandate of ensuring grid reliability at just and reasonable rates. The commission’s rulemaking targets loads greater than 20 MW and co-located hybrid facilities that combine load and generation at a single point of interconnection — a configuration increasingly favored by technology companies seeking to pair data centers with dedicated on-site power generation.
Capacity constraints are already manifesting across major grid systems. In its most recent capacity auction, PJM Interconnection procured approximately 145,780 MW, falling roughly 6,625 MW below its reserve margin target while setting record-high prices for the third consecutive auction.
The proposed rulemaking framework includes several provisions that would materially alter the interconnection landscape for large loads. Among the most significant is a requirement for expedited 60-day study timelines for flexible and curtailable loads, a departure from the multi-year interconnection queue delays that have plagued the industry. The framework would also assign 100 percent of network upgrade costs to large load customers, a principle intended to protect existing ratepayers from bearing the infrastructure burden of new demand.
FERC has already taken related action at the regional level. In a December 2025 order, the commission directed PJM to develop transparent rules for colocating data centers and other large loads at power plants — a practice known as behind-the-meter generation — and required PJM to file revised tariff provisions by February 18, 2026. That order signaled FERC’s willingness to act on interconnection issues through both national rulemaking and targeted regional directives.
The legal framework for the rulemaking is notable in its own right. The DOE’s use of Section 403 authority to direct FERC action is relatively uncommon and underscores the administration’s view that existing interconnection procedures are inadequate for the scale and pace of demand growth. Energy attorneys have noted that the compressed timeline — from ANOPR to final action in approximately six months — is ambitious by FERC standards and may face procedural challenges if stakeholders argue insufficient opportunity for comment.
The convergence of energy regulatory activity and data center infrastructure development is generating demand across multiple professional disciplines. The rulemaking process itself requires specialized expertise in FERC regulatory practice, transmission planning, and administrative law — areas where experienced practitioners are already in limited supply.
If finalized, the large load interconnection standards would accelerate project development timelines, potentially increasing demand for transmission engineers, power systems analysts, and grid reliability specialists. Utilities and independent system operators may need to expand their interconnection study teams to meet expedited review deadlines, while data center developers will require energy counsel and regulatory professionals capable of navigating the new framework.
The broader trend of load growth and grid modernization may also sustain demand for professionals in energy finance, infrastructure permitting, and compliance. Cross-functional expertise combining knowledge of power systems engineering with regulatory and legal acumen is likely to become an increasingly valuable competency.
Industry observers will be closely watching whether FERC meets the April 30 deadline with a final rule, a Notice of Proposed Rulemaking, or a request for additional time. The commission’s decision will signal not only the pace of interconnection reform but also the evolving relationship between DOE directives and FERC’s independent regulatory authority.
Beyond the immediate rulemaking, the outcome will influence state-level proceedings in major energy markets. Texas, where ERCOT operates outside FERC’s direct jurisdiction over transmission, may nonetheless adapt aspects of the federal framework as it confronts similar data center demand pressures. Grid operators in PJM, MISO, and SPP territories are expected to file compliance proposals that align regional practices with whatever national standards FERC adopts.
The proceeding also raises longer-term questions about whether the current regulatory architecture is equipped to manage load growth at the scale and speed that AI-driven demand requires. Former FERC Chairman Mark Christie has warned that data center load growth is “far exceeding any realistic possibility of new generation,” a dynamic that could force regulators and policymakers to reconsider fundamental assumptions about grid planning, cost allocation, and reliability standards.
