Piney Creek

“Located at 336 Power Ln, Clarion, PA 16214 (coordinates 41°10'40.8"N 79°26'32.0"W), this former coal plant near Williamsburg, PA, retired in 2013 and has a retired capacity of 36.2 MW (see Figure 33 and Table 22). The structures have been largely cleared, and there are no current plans for redevelopment. The 87.8-acre site is located southwest of the intersection of Interstate 80 and State Highway 68. The site is decommissioned, but its remediation status is unknown. It and 112.7 acres of nearby land are not zoned and rated as moderately rugged land. The site is treated as a presumptive brownfield, while soil and groundwater contamination are TBD. FEMA designates the site as having a very low natural hazard risk and minimal flooding risk. The parcel is designated as having possible mine subsidence potential, as it is located within or adjacent to a known coal mining area without confirmed historical mining activities; however, nearby parcels fall within a documented mineable coal area with confirmed underground mining activity and are, therefore, considered to have elevated mine subsidence risk. Rail access is ~2.5 miles away, and major roads are ~1.5 miles away. Major river access is ~12.5 miles away. Transmission lines and a substation are easily accessible on site, and a natural gas pipeline runs ~4 miles away. The nearest broadband installation is ~2 miles away. The nearest generator is ~20.5 miles away. The site sits on the Marcellus shale formation. The nearest wastewater treatment plant is ~2.5 miles away, but the nearest brownfield is ~19 miles away. There are ~186,781 people within 30 miles of the site.”

New large load

The report places sites in the PENELEC transmission zone in its large-load category, because expected generation additions there exceed projected load growth (pages 76 and 79).

The acreage-based generation estimates in Table 28 cover only the sites in zones evaluated for generation, so this site does not appear there.

Current status

Part A candidate. Part B will narrow the 21 sites to 5 to 7 priorities.

Next step

Part B will rank the sites and validate the top 5 to 7 through site visits (page 103).

Public comment

Written comments on Part A are accepted under PUC Docket No. M-2026-3059601 through October 14, 2026.

Review meetings

The report says PATER Study Review Meetings are planned for October and February (page 103).
