While the Missouri state legislature has not yet approved any laws specifically addressing smart grids, the Missouri state legislature has passed legislation focusing on net-metering standards. (S.B. 54) It has established contractual methods for entering into solar easements for solar energy technologies. [2, 3]
Missouri Public Service Commission approved Time of Use for residential and industrial customers in 1996. By 1996 the Commission approved real time pricing in 2000, and integrated demand-based management options to complement real time pricing, including thermal storage by 1996, customer determined price based curtailments by 2006, and company directed curtailment by 2009. The Commission addressed distributed generators by 1996 and included net metering by 2008. [4, 5, 6]
“In a July 2007 Order, the Missouri Public Service Commission decided not to adopt PURPA Standard 14 (“Time-Based Metering and Communications”) as enacted in EPACT 2005, “finding that the prior state action exemption applies and that no further action is required by the Commission with relation to [EPACT 1252].” The Commission agreed with its Staff’s April 2007 “Statement of Position” in which it recommended not adopting PURPA Standard 14 because utilities already provide time-based rates:
“Under statutory provision (1) quoted above, the prior state action exemption applies if the State has implemented for such utility the standard concerned (or a comparable standard). Each of the [utilities’ existing time-based] rates discussed above is set forth in a tariff authorized and implemented by action of the Commission. Therefore, the prior state action exemption applies in this case, and no further Commission activity is required under the federal statute.”
In an earlier February 2007 filing Commission Staff had urged the Commission to “determine that the prior state action exemption of EPAct 2005 does not apply to the Time-Based Metering and Communications Standard….”” 
Time of Use or Time of Day rates breaks the cost for electricity into seasonal periods with energy priced on-peak or off-peak.
The real-time pricing is based on the marginal cost of energy by the company and provided to the customer eight hours in advance of the day the power flows.
Demand-based management includes thermal storage that is company controlled, company directed load curtailment for the customer’s contracted reduction quantity, curtailments based on prices provided by the customer at which they will reduce load, and interruptible accounts that allow for equipment to be interrupted no more than 10 times per year.
Distributed generators include qualified cogeneration, small power production facility, and net metering priced either annually, seasonally, or at the company’s annual avoided fuel cost depending on the type of distributed generator and the utility.
