Risks and Uncertainties [Abstract]
Risks and Uncertainties	RISKS AND UNCERTAINTIES COVID-19 Pandemic The COVID-19 pandemic has impacted global economic activity, including electricity and energy consumption, and caused significant volatility in financial markets. The global impact of the outbreak has been rapidly evolving and many countries, including the U.S., have reacted by instituting quarantines, mandating business and school closures and social distancing measures as well as restricting travel. Responses to the COVID-19 pandemic by the State of Indiana and its residents and businesses, in particular, continue to evolve, including with respect to business and school closures and limitations and other social distancing measures and the effectiveness and timing of vaccine availability and distribution efforts. Social distancing measures designed to slow the spread of the virus, such as business closures and operations limitations, impact energy demand within our service territory. We are taking a variety of measures in response to the spread of COVID-19 to ensure our ability to generate, transmit, distribute and sell electric energy, ensure the health and safety of our employees, contractors, customers and communities and provide essential services to the communities in which we operate. In addition to the impacts to demand within our service territory, we also have incurred and expect to continue to incur expenses relating to COVID-19, including those that relate to events outside of our control. The ultimate magnitude and duration of the COVID-19 pandemic is unknown at this time and may have material and adverse effects on our results of operations, financial condition and cash flows in future periods.
