Read more in-depth information in ESIG's Brief for Decision Makers - IBR Interconnection Requirements: Status and Needs. At the end of 2023, U.S. interconnection queues contained twice as much capacity as is currently installed in … [Read more...]
Capturing the Benefits of Grid-Forming Batteries: A Unique Window of Opportunity
An estimated 427 GW of battery storage capacity was in the interconnection queues around the U.S. as of the end of 2021. In the absence of any incentives or requirements for more advanced control capabilities, all of these resources are being planned … [Read more...]
Need for North American Interconnection Process Review
Introduction The process for connecting large generators to the bulk electric system in the United States (U.S.) was designed in the early 2000’s. For about a decade, wind and natural gas resources had the largest share in the interconnection queues … [Read more...]
Inertia Trends in ERCOT
The November 2018 ESIG blog on “Implementation of Inertia Monitoring in ERCOT – What’s It All About?” discussed the importance of synchronous inertia for a power system. It included the impacts of inverter-based resources on system inertia, and an … [Read more...]
Implementation of Inertia Monitoring in ERCOT – What’s It All About?
Synchronous inertia characterizes the ability of a power system to oppose changes in electric frequency after large and sudden changes in active power production or consumption. The level of inertia present in a system at any time is dependent on the … [Read more...]
