PPL's Pennsylvania data center pipeline hits 35.3GW as QTS deal firms up

PPL Corporation's advanced-stage data center pipeline in Pennsylvania has reached 35.3GW, up 3.5GW from the second quarter and the utility's eleventh consecutive quarterly increase, the company reported on its Q3 earnings call.

The Pennsylvania-based utility, which delivers energy to more than 1.4 million customers in the state and operates two subsidiaries in Louisville and wider Kentucky, also disclosed that it has agreed commercial terms to supply roughly 2GW of generation to a QTS data center in Salem Township, Pennsylvania.

How much load is actually under contract?

Load signed under electric service agreements across PPL Electric's Pennsylvania territory rose by 300MW in the quarter to approximately 11.4GW. Of that figure, 8.5GW is under construction, an increase of 2GW from the previous quarter.

PPL said it has connected two data centers and energized 300MW of contracted load, capacity that will ramp to about 2GW. CEO Vince Sorgi framed the progression from agreements to steel in the ground as a planning tool.

"As projects move from initial agreements to ESAs and then into construction, we gain greater visibility into the infrastructure and generation that will ultimately be needed to serve this load," Sorgi said on the call.

What does the QTS deal involve?

The Salem Township arrangement was completed through Invitium Energy, PPL's joint venture with Blackstone Infrastructure, in which PPL holds a 51 percent stake. The original deal was signed under a non-binding Letter of Intent. Sorgi said the two teams are working on a long-form agreement and declined to give a timeline.

To power the data center, PPL plans two combined-cycle gas plants plus fuel cells and battery storage. The fuel cells and batteries could come online as early as 2029, with the gas plants following in 2032 and 2033, according to the utility.

Sorgi indicated more generation may follow. "If they look to expand on that Salem site and/or develop a different site, I would expect that we would be engaged in that process," he said. He added that Invitium is in talks with other customers.

"It's certainly possible that we could have another announcement by year-end, but really not putting a timeline on it," Sorgi said. He also tied the projects to grid stability in the regional transmission organization. "These projects help meet rising energy demand while strengthening the PJM grid and supporting long-term energy affordability," he said.

How is Kentucky contributing?

PPL's Kentucky economic development pipeline grew by 1GW to 14.7GW through 2032. Data centers account for 12.8GW of that total.

Who pays for the buildout?

To meet growing demand, PPL raised its capital investment plan to $25 billion for the 2027-2030 period, a $2 billion increase driven by an additional natural gas combined-cycle unit in Kentucky.

The utility said large load customers will cover most of the added investment. Its large load tariffs in Pennsylvania and Kentucky "require data centers to cover the cost of serving them," Sorgi said. "So existing customers don't bear that burden."

The tariff structure addresses a central question in the data center power boom: what does this change for residential ratepayers? Under PPL's framework, the answer is that hyperscale demand funds its own network and generation costs rather than spreading them across the 1.4 million-customer base.

What about politics?

Asked about the impact of the recent midterm elections, Sorgi suggested results in other states could work in PPL's favor. "I do think some of the election results could in some other states potentially have a chilling impact, which could drive some of those projects or future development projects to both Pennsylvania and Kentucky," he said.

With 35.3GW in the advanced pipeline, 8.5GW under construction and the QTS long-form agreement still being negotiated, PPL expects at least the possibility of another customer announcement before the end of the year.
