PPL plans a Natalie substation and 16 miles of high-voltage lines for a data center customer

The number that mattersPJM planning slides put the cost at $408 million and say the customer's load would reach about 2,000 megawatts by 2033.
Developer
PPL Electric Utilities Corporation, the Allentown-based utility subsidiary of PPL Corporation
Tenant
PPL hasn't named the customer. PJM slides describe a customer that asked for a 230 kV source near Mt Carmel, with load growing from 290 MW in 2028 to about 2,000 MW by 2033.
Current stage
PPL presented the customer's request to PJM on April 7, 2026 and its Natalie substation solution on September 8, 2026, and it told Mount Carmel Township about the project by email on October 21, 2026, hours before the supervisors met. The project still needs Pennsylvania Public Utility Commission approval, and we didn't find a PUC application. Mount Carmel Township's supervisors voted 3-0 on October 21, 2026 to oppose it, and PPL has scheduled a public open house in Elysburg for early November.
Decision body
Pennsylvania Public Utility Commission (siting approval), with planning review at PJM Interconnection's Transmission Expansion Advisory Committee
Top issues
Easements and possible eminent domain on private land, monopoles up to about 210 feet tall, scenic views and natural resources, how costs would be split between the data center customer and other electric customers, and the township's complaint about a lack of disclosure from PPL.
Key opponents
Mount Carmel Township Board of Supervisors, which adopted a resolution opposing the project on October 21, 2026
Key supporters
None named in the public record.

Coverage of this project

Know your rights

In Pennsylvania, the local zoning ordinance sets the route. A conditional use is decided by the elected governing body (supervisors, commissioners or council). A special exception or variance, and an appeal of a zoning officer’s decision, go to the Zoning Hearing Board. Each is a public hearing on a record: affected neighbors can ask for party status, cross-examine witnesses, and appeal. Municipalities can also adopt data center ordinances with enforceable standards.

Take action

Organized community opposition is the single most effective check on these projects in Pennsylvania. Show up to hearings, submit comment when it is taken, support legal and expert-witness costs, and press your municipality for a real ordinance. Pennsylvania municipalities cannot simply freeze applications, but a curative amendment under the Planning Code gives them a defined window to fix a defective ordinance.
