Flowchart of the construction phase of a wind farm

Abstract

This thesis was commissioned by VSB Uusiutuva Energia Suomi Oy. The purpose of the thesis was to study and survey the key agreements and work phases of the construction of a wind farm. The aim was to study and compile a comprehensive knowledge base, which made it possible to create a flowchart to guide the construction phase of the wind farm.

The thesis has three parts. The first part reviews wind power at a general level, VSB’s Juurakko wind farm and three different long-term power purchase agreements, i.e., PPAs. The second part reviews the construction phase of the wind farm step by step. The third part reviews the flowchart created for the thesis commissioner.

The theory and research part of the thesis, were performed using the material provided by the commissioner, concerning the Kalajoki Juurakko wind farm, which is under construction. In order to compile a better knowledge base, common literature on the construction phases of various wind and construction projects, general standards and contract terms used in Europe, as well as design and work instructions for the various work phases were used.

During the research, it was found out that the wind projects included two main building contracts covering all design and construction-related works. The two main building contracts are the Balance of Plant Agreement and Turbine Supply Agreement. Challenges to the research work were caused by the scope of the topic and its compilation into the most comprehensive and clear entity possible. The research work was comprehensive enough to create the desired flowchart for the commissioner as a final product.
