It has, of course, historically offered very generous tax subsidies, but, as we have seen, these, unlike feed-in tariffs, do not stabilize power prices.

Indeed, corporate PPAs have frequently served to render bankable US renewables projects that are also supported by tax equity financing and investment or production credits, but which would likely not have proceeded without the PPA.
