The largest US grid operator begins processing new power plant project

The largest U.S. grid operator –?PJM interconnection – announced on Wednesday that it would begin processing new power plant applications this coming week, after working through a backlog of years-long projects.

PJM controls the flow on electricity transmission lines in 13 Midwest and Mid-Atlantic States. However, the company is experiencing electricity shortages because of a recent surge of power demand by data centers, which has outpaced new supply.

The grid operator that serves about 1/5 of Americans began accepting applications for new power plants to connect to grid several months back. The deadline for submissions was Monday.

PJM reported that the grid had received over 800 applications for new power generation projects to connect to its network under a newly reformed process of interconnection.

PJM reported that 349 of the projects were battery storage. 157 were gas-fired power stations. 142 were solar farms. 65 were wind farms. Some 45 of the projects were hybrids between solar-storage and nuclear energy. Other projects included 11 projects that were hydropower and 45 others were classified as "other".

David Mills, interim president and CEO of PJM, said: "We're encouraged by the variety of generation types seeking to join PJM's generation fleet." This is great news, because we are in need of all the generation that we can get.

The new projects can generate about 220 gigawatts.

After PJM became overloaded with projects that sought to?connect to grid, it effectively stopped reviewing applications in 2022 as it worked through the backlog of applications and implemented a number of reforms.

According to an update released by PJM this month, PJM will have processed 170 gigawatts worth of projects by 2025. That's enough power to supply 130 million homes. PJM reported that 31% had been offered or signed agreements for grid connections.

Some politicians and energy trade groups were critical of the decision to freeze the entry point into the grid for 2022. This was especially true among those who supported wind and solar power, which accounted for the majority projects that applied to PJM.

"Reopening of the 'queue' is a welcome indication of 'progress. Our industry is eager to know if PJM can study and connect more energy projects in the future," said Jon Gordon. He is a senior policy director for Advanced Energy United which represents developers.
