Frey Farm Landfill Wind Energy Project

FreyConstruction of the 3.2-MW wind energy project at Turkey Hill Point was completed in December, 2010. The two (2) 1.6-MW wind turbine generators are supplying approximately 25-percent of the electrical needs for the adjacent Turkey Hill Dairy processing facility. The $9.5 Million project was completed as a partnership between PPL Renewable Energy, LLC (PPLRE), a subsidiary of PPL Electric Utilities, and the Lancaster County Solid Waste Management Authority (LCSWMA).

ARM provided all of the civil engineering and environmental consulting services for this project. ARM’s role in the project included the following services:

  • Preparation of comprehensive civil infrastructure, grading and erosion control design drawings;
  • Acquisition of National Pollutant Discharge Elimination System (NPDES) permit for the project;
  • Supported the acquisition of Zoning Approval for the project from Manor Township Officials;
  • Geotechnical investigation and foundation recommendations for the wind turbine foundations;
  • Construction-phase engineering and quality assurance testing services;
  • GIS mapping and land use evaluations;
  • Visual impact assessment and comprehensive shadow flicker study;
  • Noise assessment;
  • Preparation of Environmental Assessment (EA) for the Department of Energy (DOE);
  • Attained Federal Aviation Administration (FAA) for the project;
  • Wetlands assessment;
  • Micro-wave Interference Study;
  • Avian Impact Studies;
  • Feasibility Study;
  • Comprehensive Wind Resource Assessment.

ARM’s Feasibility Study consisted of the following tasks:

  • A desktop study to refine the probable long-term wind speed at proposed hub heights for the site;
  • ARM determined the energy production potential of the proposed installation using a variety of large-scale wind turbines;
  • Assessed electrical transmission options and interconnection viability;
  • Performed preliminary environmental investigations, including a threatened and endangered species survey, a preliminary wetlands survey, among others;
  • Identified potential FAA and FCC conflicts;
  • Evaluated zoning issues and variance requirements;
  • Performed a preliminary civil infrastructure engineering feasibility evaluation;
  • Prepared preliminary cost estimates and financial models to illustrate the potential financial performance of the project.

Following the Feasibility Study, LCSWMA and PPLRE authorized ARM to proceed with a formal 12-month wind resource assessment. A 60-meter meteorological tower equipped with six calibrated anemometers and two wind vanes was installed at the site in June 2007. ARM, in connection with its meteorological subconsultant (AWS Truewind), received and reviewed meteorological data transmitted from the tower and evaluated the site’s potential for commercial-scale wind energy production. Following the 12-month data collection period, the wind data was analyzed and a long-term wind speed projection was developed. Using the projected long-term wind speed data, ARM used its licensed software to estimate the energy production from dozens of wind turbine models. Based on wind characteristics, site conditions, economic factors, and energy production potential, ARM’s optimized analysis resulted in the selection of three potential wind turbine models that would yield the highest capacity factors, could be procured, and were ideally suited for the site.

Once the Wind Resource Assessment confirmed the viability of the project, ARM conducted a spring and fall migratory bird study to assess the potential impacts of the project on migrating predatory birds. ARM continues to assist LCSWMA and PPLRE with post-construction avian monitoring in accordance with requirements of the Pennsylvania Game Commission’s Voluntary Cooperative Agreement.
