The Notice reiterates that the physical work test focuses on the nature of the work performed, not the amount or the cost. If the work performed is of a significant nature, there is no fixed minimum amount of work, or monetary or percentage threshold required to satisfy the physical work test. The Notice also provides non-exclusive examples to illustrate physical work of a significant nature for various types of renewable energy facilities.
For geothermal facilities, it could mean physical activities that are undertaken at a project site after a valid discovery. Physical work of a significant nature does not include preliminary activities, such as planning and designing, securing financing, exploring, researching, conducting geologic mapping and modeling, and obtaining permits and licenses.
