ERCOT's "connect and manage" model gets the buzz in grid reform debates, but U.S. regions already offer a non-firm option: Energy Resource Interconnection Service. So why are IX queues still bottlenecked? Our new paper in Energy Policy investigates 🧵 👇️ www.sciencedirect.com/science/arti...

ERIS was meant to allow new generators to connect on an "as available" basis, avoiding massive upfront transmission upgrades. Yet, over the last two decades in the U.S., ERIS waiting times have gone up and ERIS use has plummeted from 50% to just 10% of active capacity.

The paper reviews 6 ISOs / 3 vertically integrated utilities and found wide variations in ERIS implementation Regions differ drastically on study methods, cost allocation, and whether congestion is managed dynamically in real-time or triggers expensive network upgrades in studies

Some takeaways? The concept of energy-only interconnection is economically sound—the challenge is the implementation. Different study assumptions can lead to wide variation in identified network upgrades but also procurement rules and resource adequacy design complicate reform
