Document Description
The purpose of this agreement is to develop, demonstrate, and test a reinforced concrete additive manufacturing technology for building low cost ultra-tall wind turbine towers onsite at the wind plant. The proposed reinforced concrete additive manufacturing technology eliminates the transportation and logistics constraints by manufacturing structurally efficient large diameter towers within the wind plant using lights weight reinforcement methods. The towers are made with locally available cementitious materials supplied by standard concrete trucks or an existing concrete batch plant within the wind plant used for casting conventional tower foundations. The construction tech will reduce technological and economic barriers to upgrading, repowering, and expanding wind power generation in CA by enabling cost effective deployment of taller towers that capture more wind energy from faster winds aloft.

Notice of Exemption

Exempt Status
Categorical Exemption
Type, Section or Code
15306
Reasons for Exemption
Class 6 consists of basic data collection, research, experimental management, and resource evaluation activities which do no result in a serious or major disturbance to an environmental resource. The project involves design studies, engineering analyses, and economic analyses of conrete wind turbine tower designs. Prototype concrete tower sections will be fabricated using a robotic arm and 3D printer, and will then be tested at the civil engineering lab of UC, Irvine.
