PPL Holtwood has announced the completion of a new, 125-MW powerhouse at its Holtwood hydroelectric facility along the Susquehanna River in south-central Pennsylvania. The powerhouse is part of a $440 million expansion to increase the plant’s generating capacity and improve fish passage over the damn.
The new powerhouse sits adjacent to the existing powerhouse and increases the plant’s generating capacity from about 108 MW to more than 230 MW. The existing powerhouse, which was completed in 1910, continued to operate throughout the project and will continue to generate power moving forward.
The new facility uses two 62.5-MW turbines that are capable of generation more electricity than the 12 existing turbines combined, according to a statement from PPL Holtwood.
The company expects to qualify for federal grants made available through the American Recovery and Reinvestment Act of 2009. The incentives were a key factor in the decision to build the facility and are expected to exceed $100 million, according to PPL Holtwood.
