In 2009, Missouri enacted the Missouri Energy Efficiency Investment Act, creating energy efficiency sales and peak reduction goals to be met through investment in demand side management. The goals outlined below were created by the Public Service Commission (PSC) in 2010, with benchmarks beginning in 2012.
|Year||Annual Sales Reductions||Annual Peak Reductions||Cumulative Sales Reductions||Cumulative Peak Reductions|
The goal of the program is to achieve all cost-effective demand-side savings. Individual utilities must file an application with the PSC for approval of their demand-side management programs; recovery for any such programs will not be permitted unless the programs were approved by the PSC and result in energy or demand savings. The Total Resource Cost Test will be considered the preferred cost-effectiveness test. The only exceptions to the cost-effectiveness requirement is programs for educational purposes or for low-income customers.
The PSC may development cost recovery mechanisms to encourage investment in demand-side programs, including capitalization of investments in and expenditures for demand-side programs, rate design modifications, accelerated depreciation on demand-side investments, and allowing utility retention of a portion of the net benefits of demand-side programs for its shareholders. As required by statute, [https://www.efis.psc.mo.gov/mpsc/Docket.asp?caseno=EW-2011-0372 Docket EW-2011-0372] was opened in May 2011 to study rate design modifications associated with demand-side cost recovery before such a program can be implemented.
