Unclogging the Grid: FERC Reforms Confront the Interconnection Bottleneck
Published February 15, 2026
New federal rules aim to streamline the process for connecting new energy sources to the power grid, but operational hurdles and the fundamental need for more transmission capacity remain significant challenges.

The U.S. power grid is facing a critical bottleneck, not in energy generation, but in connection. A massive backlog of proposed power projects, overwhelmingly renewable, is stalled in interconnection queues, waiting for approval to connect to the transmission system. This logjam represents a primary obstacle to deploying clean energy at the scale required to meet climate goals and growing electricity demand.
In response, the Federal Energy Regulatory Commission (FERC) has issued Order No. 2023, a landmark rule overhauling the generator interconnection process. The rule shifts the system from a speculative 'first-come, first-served' model to a more rigorous 'first-ready, first-served' approach, requiring projects to be more mature before entering the queue. This policy change represents a significant attempt to clear the backlog by prioritizing viable projects, but its success hinges on effective implementation by grid operators and a parallel focus on expanding physical transmission infrastructure.
The Scale of the Interconnection Logjam
At the end of 2022, over 2,000 gigawatts of generation and storage capacity were waiting in interconnection queues across the U.S., a volume that dwarfs the capacity of the current operating grid. The majority of this proposed capacity is solar, wind, and battery storage. The existing 'serial' study process, where each project is analyzed sequentially, has proven incapable of handling this volume, leading to years-long delays and high withdrawal rates as speculative projects clog the system.[1][2]
Transfer Pathway: From Serial Processing to Cluster Studies
FERC Order No. 2023 mandates a fundamental shift in the interconnection process. Instead of studying projects one by one, transmission providers must now evaluate them in large groups, or 'clusters.' This approach is designed to be more efficient and to provide a more holistic view of the grid upgrades needed to accommodate new generation. The rule also imposes firm deadlines for completing these studies and financial penalties for providers who fail to meet them. Furthermore, it requires projects to demonstrate commercial readiness with financial deposits and site control, aiming to weed out speculative proposals early.[3][4]
False Positives: New Rules Don't Build New Wires
While procedural reforms are a critical step, they do not, on their own, create the physical transmission capacity needed to connect new resources. The interconnection process identifies necessary grid upgrades, but the separate, often lengthy, process of planning, siting, and building new high-voltage transmission lines remains a major hurdle. Without a proactive, long-range transmission planning process, the queue reforms may simply identify needed upgrades faster without accelerating their construction. The success of Order No. 2023 is therefore intrinsically linked to broader efforts to expand the grid.[5][6]
Skeptical lens / counterpoint
Reforming the interconnection queue is a necessary but insufficient condition for accelerating the energy transition. The fundamental problem is a lack of physical transmission capacity. Even a perfectly efficient queue process will still identify the need for new lines that take years or decades to approve and build. Without parallel reforms and investment in long-range proactive transmission planning, the interconnection bottleneck will persist, merely shifting from a procedural one to a physical one.[6][7]
What changed recently
The complexity of implementing these reforms was highlighted when the Federal Energy Regulatory Commission (FERC) granted transmission providers an extension for compliance with Order No. 2023. The deadline was pushed back to provide more time for developing the necessary software and procedures to manage the new cluster study process, indicating that the transition from policy to operational reality is a non-trivial undertaking for grid operators across the country.
What to watch next
- Implementation progress and outcomes of FERC Order No. 1920, which addresses long-term regional transmission planning and cost allocation, as its success is critical to building the infrastructure identified in the interconnection process.
- Milestones from the Department of Energy's Interconnection Innovation e-Xchange (i2X) initiative, which aims to develop and share solutions for improving interconnection.
- Performance metrics from Regional Transmission Organizations (RTOs) and Independent System Operators (ISOs) on their first few cluster study cycles under the new rules.
