This adder incentivizes project developers to use American-made content in their advanced energy projects by increasing the value of their underlying tax credits – i.e. the Investment Tax Credit (ITC) or Production Tax Credit (PTC) – by 10%. To qualify, all of the steel used in a project and a significant share of the underlying components must be made in the U.S.
