Williamsburg

“Located at 774 Juniata River Rd, Williamsburg, PA 16693 (coordinates 40°28'13.7"N 78°12'27.8"W), this former coal plant retired in 1990 and has a retired capacity of 43.3 MW (see Figure 37 and Table 26). The site is owned by the Williamsburg Borough and needs to be cleared for development aside from a substation. The 37.9-acre site is located north of Williamsburg, which is just off US-22. It and an adjacent 4.3-acre site is not zoned and rated as moderately rugged. It is treated as a presumptive brownfield with confirmed soil contamination and groundwater contamination TBD. FEMA designates the site as having a very low natural hazard risk but in a floodway. The parcel and nearby parcels are not located within or adjacent to a documented coal mining area and are, therefore, considered to have minimal mine subsidence potential. Access to the rail system is ~8 miles away; major roads are ~2.5 miles away, and river access is ~6 miles away. The nearest transmission lines are ~2.5 miles away, and the nearest substation is ~6 miles away. The nearest natural gas lines are ~10 miles away. The nearest broadband installation is adjacent to the site. The nearest generator is ~20 miles away. The site is ~10 miles away from the Marcellus shale formation. The nearest wastewater treatment plant is ~1 mile away, and the nearest brownfield is ~12 miles away. There are ~347,184 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).
