Jerry Crescenti, BS, MS

Jerry Crescenti, BS, MS

Gennaro (Jerry) H. Crescenti (B.S., M.S.) joined V-Bar in 2016. He has over 25 years of experience as a meteorologist including over 12 years working as a meteorologist for the two largest wind energy providers in the world: FPL Energy (now NextEra) and Iberdrola Renewables (formerly PPM Energy). He started his career at the Woods Hole Oceanographic Institution and was a research meteorologist in NOAA’s Air Resources Laboratory. His principal area of expertise includes in-situ meteorological instrumentation, ground-based remote sensors, observation techniques, boundary layer meteorology, turbulence, air-sea interaction and wind resource and project energy assessment. At FPL Energy, Mr. Crescenti provided meteorological support to development and operation of numerous wind farms. Responsibilities included wind resource assessments, site surveys, wake loss analysis, turbine layout and optimization, investigation of operating assets, relocation of underperforming wind turbines. At Iberdrola Renewables, Mr. Crescenti was Director of Meteorology and managed a team that was responsible for wind and solar resource and project energy assessments. His responsibilities included specification of meteorological instruments, configuration, and deployments, on-site surveys and staking locations for meteorology towers, sodars and lidars, quality assurance and quality control of on-site data sets, data analysis, wind and solar resource and project energy assessments, wind turbine layout design using GIS, wake loss determination, turbine micrositing, site suitability analysis, operational performance of wind farms and reconciliation against original energy predictions, and evaluation of external wind resource assessments and reports from external consultants.
