Indiana’s commission rule (170 IAC 4-4.3 (as amended by LSA #25-368, IURC RM #24-01)) does not bind electric cooperatives; Western Indiana Energy REMC sets its own interconnection policy. We confirm its form on the first project. Municipal utilities and REMC/electric cooperatives are not bound by 170 IAC 4-4.3 or IC 8-1-40 (IC 8-1-40-4 excludes them) and set their own interconnection and DG policies (many through Hoosier Energy / Wabash Valley Power member policies, not reviewed).
