The Developers Closing on Schedule Have One Thing in Common: They Can Build Power Without Waiting for the Grid

In some PJM sub-markets, grid interconnection timelines now exceed 10 years. The developers closing deals on schedule aren't waiting for the queue.

They selected sites where they can build their own power in 18 to 24 months — and they evaluated that capability before they even called the utility.


Behind-the-meter generation — aeroderivative gas turbines, fuel cells, BTM microgrids — has moved from contingency plan to first-screen site selection criterion.


Not a fallback. A primary development strategy.


The numbers back this up:

  • 56% of developers are now actively exploring on-site or co-located power generation.

  • A 500 MW data center using a BTM-first approach can reach full operation

  • 3 to 5 years faster than one waiting on traditional interconnection.


And as full-cost-of-service tariff structures spread across more states, the cost advantage of grid power at scale is narrowing — fast.


The operators who saw this coming didn't just switch strategies. They rebuilt their site evaluation sequence.


Power autonomy potential — a site's capacity to host behind-the-fence generation — now gets scored before conventional grid access. Not after.


In today's issue of The PillarPoint Brief:


— Why the conventional site selection sequence is now producing the wrong answer

— The three-part grid-independence audit operators are running at first screen: gas pipeline proximity and capacity, air quality permitting jurisdiction, and generation footprint and zoning compatibility


— How to score BTM feasibility alongside grid access — and when the BTM score wins

— What the Project Jupiter (New Mexico) fuel cell pivot signals about where the market is heading on generation technology


If your power diligence stops at the utility call, you're missing the variable that's moving deals.
