After fifteen months of review and debate, most of the rules implementing the energy efficiency and peak demand reductions requirements set forth in SB 221 are now final. Final modifications to the rules were filed on October 28, 2009. And although the Public Utilities Commission of Ohio granted rehearing for the limited purpose of reviewing several rules, the remaining rules are in effect. A summary of the energy efficiency rules is available here. A full copy of the rules is available here.
