Jacob C. Stacken - Wind Assessment Technician and Meteorologist

In my renewable energy career, I have worked on more than 30 utility-scale wind projects ranging in capacity from 10 MW to 400 MW. I have designed, executed and managed the energy assessment for most of these projects. As part of my responsibilities, I have managed more than 60 meteorological towers ranging in height from 30 meters to 155 meters. Most of my energy assessment work, modeling and predictions have been verified and approved by multiple third party assessors. I have performed energy assessment work for big organizations like the U.S. Air National Guard, and smaller companies like Seventh Generation Energy Systems. Some of the wind turbines that I have modeled with are GExle, REpower MM92, Vestas Vxx and V100, Siemens 2.3MW, Acciona 1.5MW and 3MW, Gamesa G90, Nordex N100, Suzlon, and others.

Kiril Lozanov - Wind Energy Analyst

Mr Lozanov is a trained user of WASP and Windfarmer software, which he utilizes for gathering site wind data and creating an optimized wind project, including maximizing energy production while maintaining required setbacks for maximum noise levels and shadow flicker hours at nearby residences. Mr Lozanov manages the deployment of the SODAR wind measurement device, as well as other field data collection equipment, including noise measurement and shadow flicker measurement after turbines have been installed. Mr. Lozanov has had an extensive renewable energy career. He came to WES from EcoEnergy LLC an Illinois based wind developer, where he was the Energy Assessment Manager. His experience includes working on more than 30 utility-scale wind projects ranging in capacity from 10 MW to 400 MW. He has designed, executed and managed the energy assessment for most of these projects and has managed more than 60 meteorological towers ranging in height from 30 meters to 155 meters. His experience includes working for both small and large entities, such as U.S. Air National Guard, municipal utilities and private developers. He has experience with modeling turbines from many manufacturers such as GE, REpower, Vestas, Siemens, Acciona, Gamesa, Nordex, Suzlon, and others. Mr. Lozanov has a degree in Forestry from Sofia University in Bulgaria.

Diana Cohen - Office Manager/Bookkeeper
and Project Technician

Ms. Cohen assists in various aspects of wind development projects at WES Engineering. She is responsible for the data quality checks on wind data downloaded daily from measurement devices and generating reports. She assists in the creation of Federal Grant applications as well as creates GIS maps for locating potential turbine sites. Ms. Cohen is responsible for ensuring the office is running efficiently in addition to bookkeeping and payroll. Her past work experiences, working as a Project Manager at a custom database developer, a Contract Coordinator and Network Administrator at energy organizations, brings WES an array of skills necessary to perform this multi faceted position. Ms. Cohen has a Bachelor of Science degree in Environmental Science from Antioch College in Yellow Springs Ohio.

Alex DePillis - Wind Engineer

Mr. DePillis specializes in wind resource assessment and project development for commercial wind systems. He has worked for 15 years as engineer and business developer in wind and diversified energy companies, with an eight-year stint being responsible for the State of Wisconsin's renewable energy efforts at the Wisconsin Division of Energy. There, he managed a fleet of meteorological towers and an effort to map wind speeds in the entire state of Wisconsin. More recently, he managed the meteorological towers for EcoEnergy, a wind developer covering the Upper Midwest and beyond, and added project development to his skills. At WES Engineering, he is deploying and supporting both LIDAR and SODAR.
