The story at a glance

Pennsylvania Public Utility Commission (PUC) and Office of Consumer Advocate filed comments with the Federal Energy Regulatory Commission opposing incentives requested by Kammer Juniata Transmission, LLC—a joint venture of NextEra Energy Transmission (75% equity) and Exelon Transmission (25%)—for a proposed 220-mile, 765-kV power line from Marshall County, West Virginia, to Perry County, Pennsylvania. The line, endorsed by PJM Interconnection in February 2026 to address grid reliability amid data center growth, faces scrutiny over shifting construction and abandonment costs to customers before state approvals. This is reported now amid the developers' recent FERC filing seeking incentives to start next month.

Key points

Developers seek FERC approval for 100% recovery of construction costs during building, 100% recovery if abandoned due to external factors, an 11.25% return on equity (including 0.5% new entrant adder), and 60% equity/40% debt financing.
PUC argues these incentives are unnecessary for "massive, established parent corporations" like NextEra and Exelon, and should wait for certificates of public convenience from Pennsylvania and West Virginia regulators.
Pennsylvania customers could bear up to $678 million of the $1.7 billion cost through utility rates.
Project crosses ten Pennsylvania counties, involves over 1,000 landowners, federal and state lands, and faces long lead times for 765-kV equipment (four years).
PJM selected the project in its 2025 Regional Transmission Expansion Plan after a 60-day competitive window, despite PUC concerns over insufficient competition.
Prior similar project, Potomac-Appalachian Transmission Highline, was canceled but customers paid developers $250 million due to incentives granted since 2008.

Details and context

The Kammer Juniata line aims to fix thermal violations on lower-voltage lines and replace an aging 500-kV line, supporting reliability for 67 million people across 13 states as Eastern Pennsylvania data centers strain the grid by 2031. Developers describe their venture as a "startup" with no credit history to justify incentives, but PUC notes the backing of major firms reduces risk.

State approvals via certificates of public convenience are needed for eminent domain on new rights-of-way; without them, land must be bought piecemeal. Environmental permits are required for crossings of waterbodies, highways, farms, and sites with historical or cultural value.

A prior PJM-endorsed 290-mile line was abandoned after states denied certificates, leaving customers to cover costs under similar FERC incentives.

Key quotes

Pennsylvania Office of Consumer Advocate: “Ratepayers should not be the ‘piggy bank’ subsidizing risky projects for transmission owners or AI data centers.”[[1]](https://www.post-gazette.com/business/powersource/2026/04/20/pennsylvania-power-transmission-line-kammer-juniata-nextera-exelon-puc/stories/202604160041)

PUC on one incentive: “effectively makes consumers the bank for transmission developers” by allowing 100% construction cost recovery; on another: “effectively makes [consumers] the insurer of last resort” for abandonment.[[1]](https://www.post-gazette.com/business/powersource/2026/04/20/pennsylvania-power-transmission-line-kammer-juniata-nextera-exelon-puc/stories/202604160041)

Developers: “We are confident that the project addresses PJM-identified reliability needs and will help strengthen the regional grid.”[[1]](https://www.post-gazette.com/business/powersource/2026/04/20/pennsylvania-power-transmission-line-kammer-juniata-nextera-exelon-puc/stories/202604160041)

Why it matters

The dispute highlights tensions between grid upgrades for growing electricity demand and protecting ratepayers from unproven project costs in a region facing data center expansion. Pennsylvania utility customers could face higher bills for a line not yet state-approved, with risks of abandonment or overruns shifted via incentives. Watch FERC's review of the incentives and state certificate applications expected next year, as either denial or approval could delay or reshape the project timeline to 2031 operation.

What changed

Before the FERC filing, PJM endorsed the project in February 2026 without state incentives or cost recovery locked in. Now, developers seek federal approval for advanced rate treatments to begin construction next month, prompting PUC and Consumer Advocate protests filed in early April. PUC comments on April 7, 2026, marked formal opposition urging FERC to withhold incentives until state reviews.[[1]](https://www.post-gazette.com/business/powersource/2026/04/20/pennsylvania-power-transmission-line-kammer-juniata-nextera-exelon-puc/stories/202604160041)[[2]](https://www.puc.pa.gov/press-release/2026/puc-raises-concerns-over-222-mile-transmission-project-proposed-across-ten-pennsylvania-counties-04082026)

FAQ

Q: What incentives is Kammer Juniata seeking from FERC?

A: The developers request 100% recovery of construction costs during building, 100% recovery if abandoned for external reasons, an 11.25% return on equity, and a 60% equity/40% debt structure. PUC says these shift risks to customers before state approvals. The filing aims to start incentives next month for the $1.7 billion project.[[1]](https://www.post-gazette.com/business/powersource/2026/04/20/pennsylvania-power-transmission-line-kammer-juniata-nextera-exelon-puc/stories/202604160041)

Q: Why does PUC oppose the incentives?

A: PUC argues they provide "needless corporate welfare" to backed developers, make consumers a "bank" and "insurer," and are premature without Pennsylvania and West Virginia certificates of public convenience. The agency notes the project lacks state review despite PJM endorsement.[[1]](https://www.post-gazette.com/business/powersource/2026/04/20/pennsylvania-power-transmission-line-kammer-juniata-nextera-exelon-puc/stories/202604160041)

Q: What grid issues does the line address?

A: PJM identified reliability needs from thermal violations on 230-kV lines and an aging Juniata-Sunbury 500-kV line, worsened by Eastern Pennsylvania data center growth stressing the grid for 67 million people. Operation is targeted for June 2031.[[1]](https://www.post-gazette.com/business/powersource/2026/04/20/pennsylvania-power-transmission-line-kammer-juniata-nextera-exelon-puc/stories/202604160041)

Q: What risks could lead to project abandonment?

A: Denial of state certificates, failure to acquire land from over 1,000 owners, permit issues for lands and water crossings, equipment delays, or PJM deeming it unnecessary. A past project was canceled, costing customers $250 million.[[1]](https://www.post-gazette.com/business/powersource/2026/04/20/pennsylvania-power-transmission-line-kammer-juniata-nextera-exelon-puc/stories/202604160041)
