IC 8-1-42-13: Underground cables; aboveground infrastructure; depth of buried cables; cables and lines outside of project site

Sec. 13. Except as otherwise allowed by IC 36-7-4-1109, if a project owner installs a CSE system in a unit, all cables of up to thirty-four and one-half (34.5) kilovolts that are located between inverter locations and project substations shall be located and maintained underground, as feasible. Other solar infrastructure, such as module-to-module collection cables, transmission lines, substations, junction boxes, and other typical aboveground infrastructure may be located and maintained above ground. Buried cables shall be at a depth of at least thirty-six (36) inches below grade or, if necessitated by onsite conditions, at a greater depth. Cables and lines located outside of the CSE system project site may:

(1) be located above ground; or

(2) in the case of cables or lines of up to thirty-four and one-half (34.5) kilovolts, be buried underground at:

(A) a depth of at least forty-eight (48) inches below grade, so as to not interfere with drainage tile or ditch repairs; or

(B) another depth, as necessitated by conditions;

as determined in consultation with the landowner.
