Seems like it would have to be in its own closed-loop, as in any thermal-powered power plant, traveling to and from the heat source via a heat-exchanger, or the hot well working fluid traveling from the bore-hole to and from the heat-exchanger.
Carson City, Nevada sits atop a super-volcano caldera, and they tap this as a source of 'shallow' heat.
Seems like these 'shallow', thin lithosphere locations, close to the magma, would be the 1st-choice locations. They'd require the minimum drilling and completion costs, plus get into service the quickest, all else being equal.

Really: Carson City?? Ormat is at the southish end of Washoe county about 15 miles from Carson and I believe there are no commercial thermal operations in Carson except for home heating in a limited way.

The other super volcano is under Mono lake/and or Bishop Mammouth mountain which is a bit farther south. Same distance north west is mt Lassen.
Bunches of thermal east and around Elko. If I want, a 500 ft deep well gives me 150f water as there are numerous geothermal houses in my neighborhood but the city won't issue a permit..
400 500 & 800 series of stainless pipe, good to 600f, inconel and hastelloy good to 1800-2200f as used in jet engines aft sections
