SB 412 - This act modifies provisions of the Missouri Energy Efficiency Investment Act. This act modifies the definition of "demand-side program" to include the utilization of combined heat and power technology to generate electricity from waste heat to assist customers with reducing the amount of electricity delivered. This act also modifies notification procedures for customers participating in demand-side programs. This act requires that a customer with one or more accounts having a demand of 5,000 kWh or more, a customer operating an interstate pipeline pumping station, or a customer with a demand of 2,500 kWh or more and a comprehensive energy efficiency program, to give written notification if they do not elect to participate in demand-side measures offered by the electrical corporation on either all or some of the customer's accounts. Starting on the first day of the billing cycle occurring after the customer provided notification, no demand-side charges shall be included on the customer's bill for such accounts. After notification has been given, such customer shall not be eligible to participate in demand-side programs unless the customer provides an additional written notice rescinding its previous notice. Currently, customers of electrical corporations that receive either a low-income housing or historic preservation tax credit are not eligible to participate in any demand-side program offered by an electrical corporation if such program offers a monetary incentive to the customer. This act repeals this provision. This act is identical to provisions contained in SB 190 (2017) and HB 628 (2017), contains provisions that are identical to provisions contained in HB 648 (2017) and CCS#2/HCS/SCS/SB 112 (2017), and contains provisions that are similar to provisions contained in SB 214 (2017), SB 412 (2017), and SS/HCS/HB 2689 (2016).
