Green Energy Summer School (GESS)

21 August - 8 September 2023 in Berlin

RENAC’s Green Energy Summer School (GESS) takes place at the RENAC Training Centre in Berlin, Germany each summer. Summer school programming reflects the educational needs and professional goals of those working in the green energy sector. GESS content covers foundational topics in green energy and provides insights into cutting-edge technology. Courses are designed for different target groups, taking their knowledge background into consideration.

This year’s GESS programme includes three separate courses. It offers participants the opportunity to learn about:

  • Renewable energy (RE) sources and the various technologies to harness them
  • PV project management and economics
  • Wind turbine technology

During the first week, participants can take the Introduction to Renewable Energy Technologies course. This foundational RENAC course is designed to suit the interests of technicians and non-technicians alike who want to enhance their career prospects by acquiring a comprehensive introduction to renewable energy technologies. For the first time this year, this course will incorporate an introduction to hydrogen session, focused on hydrogen as an emerging energy technology.

During the second week, participants are offered the Management and Economics of Photovoltaic Projects course, which covers PV markets and technologies, solar power project management, and the financing of PV projects.

In the third week, participants are offered the Wind Turbine Technology course. After completing this course, participants will be familiar with state-of-the-art wind turbine generators, how they are made and work, available market models, and how they are operated in a wind farm to produce reliable, competitive green energy.

Content is delivered by experts in their respective fields utilising case studies and hands-on exercises. Participants will gain a theoretical as well as practical understanding of topics covered in the courses. Through group assignments, participants work as part of a team with professionals from many different countries.

Individuals can opt to take only one or both courses. After successfully completing each course, participants will receive a certificate of attendance from RENAC.
