Ameren Illinois and PowerRunner, LLC, today announced that Ameren’s innovative, real-time loss (RTL) analysis methodology has been filed with the Illinois Commerce Commission and has been accepted as the new tariff for determining the quantification and allocation of technical losses and related Distributed Unaccounted for Energy (DUFE) across various voltage (loss) classes. The tariff went into effect on June 1, 2018.

Ameren’s RTL analysis was developed on the PowerRunner Energy Platform™. PowerRunner is an intuitive, business-centric application that joins disparate internal and external time-series data sources through a highly configurable data management layer to create an enterprise utility business analytics solution. PowerRunner was originally deployed at Ameren Illinois in 2013 to support the company’s anticipated AMI physical and financial analytics initiatives.

The RTL analysis aggregates hourly service point load forecast data by voltage (loss) class vs. the hourly system load to determine the loss factors per voltage class for every hour of the day. This new method reduces the time it takes to perform a loss study from more than a year to seconds. In addition, it more accurately accounts for real losses across the system and reduces DUFE.

The PowerRunner RTL methodology operates on 8760 hours of AMI and system load data to create hourly system-loss factors for each voltage class. Localized and real-time analyses of losses are further calculated by leveraging available upstream hourly SCADA data to determine loss factors by specific loss class, hour and circuit. This new RTL methodology could also be useful for other system evaluation applications.

“Using traditional analysis methods, it used to take Ameren and other utilities well over a year to conduct an SLA at a cost well into six figures,” said Keith Hock, Director of Transmission Technical Services & Operations Planning, Ameren Services. “Now we can provide a highly-detailed loss study for any hour of any day, on demand.”

“The reduction, predictability and equitable allocation of DUFE reduces volume and price risk for electricity suppliers,” said Hock. “Ameren will now be able to offer day-ahead forecasts of hourly-loss factors to suppliers and customers. This temporally-granular loss analysis will also provide superior insight for our long-term planning decisions.”

“PowerRunner’s ability to create unique models for every distribution system asset provides utilities with the visibility to manage real time grid operations, and more effectively develop localized system improvements to support bi-directional power flow from distributed energy resources,” said Jason Iacobucci, President of PowerRunner, LLC. “The PowerRunner Energy Platform provides a foundational component for managing a transactive energy grid.”
