A utility-filed document in a Missouri Public Service Commission working case, detailing how retail rules and utility practices may need to adapt for grid edge resource aggregations. Ameren Missouri’s response emphasizes validation and compliance checks at the distribution level before grid edge resources can participate in wholesale markets. It raises consumer protection issues (e.g., requiring grid edge resource aggregators to register with the state and adhere to marketing standards to prevent fraud) . It discusses the need for enhanced metering and telemetry so that when a customer’s behind-the-meter resource provides wholesale services, the utility can measure those injections separately—ensuring retail billing credits (like net metering) and wholesale payments don’t overlap or double count the same energy . The filing also notes potential distribution infrastructure upgrades and operating procedures to maintain safety/reliability with aggregated grid edge resource dispatch (for instance, communication protocols for outage coordination and mechanisms for the utility to override or constrain aggregator dispatch for local grid safety). Overall, it outlines how the PSC should develop rules on interconnection, data sharing, dual participation, and dispute resolution between aggregators and utilities.
