Client Needs:
Jersey Central Power and Light Company (JCP&L) and PSEG Fossil, LLC received a new FERC license for their 420 MW Yards Creek Pumped Storage Hydroelectric Project (Project) in May 2013. The Project consists of an upper and lower reservoir, a powerhouse with three reversible pump turbines, and associated electrical and water conveyance features. As part of the License Order approving new higher reservoir operating levels, FERC required the Licensees to design and construct an emergency spillway on the upper reservoir.

Kleinschmidt Solution:
Kleinschmidt assisted in the evaluation of a number of design options throughout the relicensing process before ultimately working with FERC and the Licensees to select a horseshoe-shaped spillway design that took advantage of an existing rock peninsula on the upper reservoir. Because of limited construction windows available due to power needs, the upper reservoir spillway project was put on a very aggressive schedule for design, permitting and construction. Kleinschmidt scientists worked with state and Federal regulators to develop individual species protection plans that were required prior to construction while Kleinschmidt engineers managed a sub-surface geotechnical investigation and site topographical survey that was needed to complete final design. Kleinschmidt finalized the spillway design in fall 2013 which included preparation of required technical documentation and permitting submittals for local, state and federal approvals. The project is currently on schedule with a planned construction start in March 2014. Kleinschmidt will be performing on-site construction quality assurance in accordance with FERC QCIP requirements.

Client Benefits:
Kleinschmidt’s knowledge of the site and relationship with the client, together with our FERC dam safety and structural expertise helped to develop the detailed design information needed to secure contractors, gain regulatory approvals, and navigate through the compliance requirements to meet the aggressive schedule.
