JUDGMENT OF RECORD ·
Batteries are winning the fast lane onto the grid. PJM's first fast-track approvals were mostly storage, as WoodMac puts 4-hour batteries 65% to 75% below new gas peakers.
On Oct 8 PJM approved the first three projects in its Expedited Interconnection Track, 2.1GW in all. Engie's two battery projects in Pennsylvania and Ohio make up nearly 1.7GW. LS Power's 455MW gas uprate at Hunterstown is the third. All are due online by mid 2029.
On Oct 8 Wood Mackenzie said 4-hour storage with a 2026 start is 65% to 75% cheaper than new gas peakers in the US. It projects gas turbine prices near $600/kW by end 2027, up 195% since 2019. On Oct 9 PowerLines reported a record $4.5B of utility rate requests in Q3, and $23.1B so far in 2026.
The layer moving is infrastructure. Gas turbines are scarce and costly, so storage takes the fast interconnection slots while customers pay rising rates. Cost Collapse governs but stays Inactive: the gap is about 3x to 4x, not 10x. Confidence is Medium: PJM's picks are public, but the cost gap is one firm's model.

WHAT WOULD PROVE THIS WRONG
PJM's next fast-track round selects mostly gas, or Engie's 1.7GW of storage misses its mid 2029 online date.
