- Gas turbines reserved: More than 5 GW
- Data center pipeline: 31.8 GW in advanced planning
- Under signed agreements: More than 11 GW
- Potential JV investment: $12.5 billion to $15.0 billion through 2032
- First turbines online: 2031 to 2032
PPL Corporation and Blackstone Infrastructure have reserved more than 5 GW of combined-cycle gas turbines for Pennsylvania. The two companies hold the turbines through Invitium Energy, a joint venture they formed in July 2025. PPL owns 51 percent and Blackstone owns 49 percent. PPL told investors on August 7 that Invitium carries $12.5 billion to $15.0 billion of potential investment through 2032. The utility also reported 31.8 GW of data center demand in advanced planning. More than 11 GW of that sits under signed electric service agreements. The turbines will not run soon. PPL expects the first combined-cycle units in the 2031 to 2032 timeframe.
Why It Matters
The gap between 31.8 GW of advanced-stage interest and 11 GW of signed agreements is the number to watch. Advanced-stage pipelines shrink once developers post collateral. PPL President and CEO Vincent Sorgi told investors that bilateral contracting will be the main pathway for new generation. That shifts risk off the capacity auction and onto the counterparty. A signed service agreement buys a large load a queue position now, not electrons. The first Invitium megawatt is still five years out.
What Is Being Built
Reservation agreements are not firm orders. They hold a place in a manufacturing slot. PPL has not named the turbine supplier. Invitium has paired the reservations with the two other scarce inputs, site control and queue position. PJM Interconnection accepted about 5 GW of Invitium projects. The venture also controls Pennsylvania sites big enough for 8 GW to 14 GW of generation.
Gas is not the first thing to arrive. PPL reported that batteries and other shorter-lead-time equipment could contribute in 2029 or 2030. The venture has not named a customer. PPL expects to sign at least one commercial supply agreement for Invitium by the end of 2026.
The Pipeline Behind It
The demand side of the case grew again this quarter. PPL Electric Utilities reported 31.8 GW of data center load in advanced planning, up from 28.3 GW three months earlier. More than 6.5 GW is under construction. Kentucky adds a separate pipeline of 11.6 GW. Louisville Gas and Electric and Kentucky Utilities project 3.7 GW of new load online by 2032. Those two utilities carry $3.5 billion to $4 billion of investment from 2027 to 2032.
Critical Perspective
PPL reports 31.8 GW in advanced planning against 11 GW under signed service agreements, so most of that pipeline is interest rather than contract. Pacific Gas and Electric published the same shape this year, 12.7 GW of data center interest against 490 MW under a signed agreement. The Public Utility Commission of Texas is auditing a 474 GW queue for exactly that reason, and PJM rebuilt its interconnection process after developers declined to post collateral. If the first Invitium unit cannot run before 2031, how much of the 11 GW under contract today will still be waiting for it?
