PJM eyes option to jumpstart surplus interconnection pathway

This is a grid-planning story, not a home-improvement one, but it touches on why power in parts of the country may get tighter or looser in coming years. PJM, the grid operator covering much of the mid-Atlantic and parts of the Midwest and South, has been struggling to line up enough power supply — it missed its reserve targets in its last two capacity auctions, with shortfalls growing to nearly 7 gigawatts for 2028-29. One fix PJM is now pursuing more seriously: letting new solar, wind, and battery projects plug into the grid at existing power plants by using capacity those plants aren't fully using, a process called surplus interconnection service. This can bring new power online faster and cheaper than building brand-new grid connections, but PJM's rules have made it hard to actually do, and only two of eight applications since 2023 have been approved. PJM is now considering rule changes, including how battery-plus-solar "hybrid" projects can operate, to make this pathway more workable.

For homeowners, this is background context rather than something requiring any action. Faster, cheaper ways to add power supply — especially batteries and solar built onto existing plants — could help ease the kind of supply crunches that show up in rising electricity bills or reliability concerns, particularly in PJM states. Indiana and Virginia have also passed laws directing their utilities to study this option. There's no rebate, deadline, or program here for individual homeowners to act on — it's a look at how grid operators are trying to keep the lights on and prices in check as demand grows.
