PPL, Blackstone's Invitium Reserves 5+ GW of Gas Turbines for PA

Invitium Energy, the joint venture PPL Corporation owns 51% of alongside Blackstone Infrastructure, has secured reservation agreements for more than 5 gigawatts of combined-cycle gas turbines and gotten roughly that same amount accepted into PJM’s interconnection queue, PPL disclosed alongside its second-quarter 2026 earnings. The venture has also lined up Pennsylvania land capable of hosting 8 to 14 gigawatts of new generation, positioning it as one of the largest dedicated power suppliers now queued to serve hyperscale data centers on the PJM grid.

Why it matters

For a developer or hyperscaler picking a Pennsylvania site, turbine reservations and queue position are the real gate, not zoning or a signed lease. PJM’s interconnection backlog has stranded projects for years without a path to power; Invitium’s 5+ GW already sitting in the queue, tied to turbines it has under contract, is a rare case of a specific site having both. PPL CEO Vincent Sorgi told investors the venture expects one or more commercial customer agreements to be announced this year, which is the signal site owners should watch, not the groundbreaking. Until a named data center operator signs, the capacity is reserved but unassigned.

The numbers

The reserved turbine capacity, more than 5 gigawatts, represents $12.5 billion to $15 billion of potential investment through 2032 at the joint-venture level, according to PPL’s own disclosure, wider than the flat $15 billion figure some coverage has used. The secured sites can support 8 to 14 gigawatts total, meaning the turbines already reserved cover well under half of the identified land. PPL holds 51% of Invitium; Blackstone Infrastructure holds the balance. More on the national market, where data-center power has become the binding constraint on where campuses get built.

What’s next

PPL does not expect Invitium to contribute material earnings until the gas turbines come online, projected for 2031 or 2032, though battery installations tied to the same sites could begin generating revenue as early as 2029. For developers scouting Pennsylvania sites now, the near-term marker is not construction, it is whether Invitium announces the named customer agreement Sorgi flagged for this year. That signature, more than any turbine delivery date, will show which sites in the 8-to-14-gigawatt pipeline actually clear first.
