Regulatory Assets and Liabilities Disclosure [Abstract] |
Regulatory Matters | Regulatory Matters COVID-19 Regulatory Filings In response to COVID-19, we received approvals or directives from the regulatory commissions in the states in which we operate. The ongoing impacts of these approvals or directives are described in the table below:
Jurisdiction | Moratorium in Place? | Regulatory Asset balance as of March 31, 2021 (in millions) | Deferred COVID-19 Costs
Columbia of Ohio | No | $ | 2.0 |  | Incremental operation and maintenance expenses
NIPSCO | No | $ | 12.0 |  | Incremental bad debt expense and the costs to implement the requirements of the COVID-19 related order
Columbia of Pennsylvania | No | $ | 7.1 |  | Incremental bad debt expense incurred since March 13, 2020 above levels currently in rates
Columbia of Virginia | Yes | $ | 0.1 |  | Incremental incurred costs, subject to an earnings test review
Columbia of Maryland | No | $ | 1.1 |  | Incremental costs (including incremental bad debt expense) incurred to ensure that customers have essential utility service during the state of emergency in Maryland. Such incremental costs must be offset by any benefit received in connection with the pandemic
On March 11, 2021, the Pennsylvania PUC adopted an order, which lifted its prior pandemic-related moratorium on service terminations for non-payments of utility bills beginning April 1, 2021. Pursuant to that order, Pennsylvania utilities are required to offer payment plans on billing arrearages, with the length of such payment plans depending on customers' income levels. The longest such payment plan would be a minimum of five years for residential customers with incomes below 250% of the Federal Poverty Level. For Columbia of Virginia, the currently effective legislative and regulatory directives related to the COVID-19 pandemic require utilities to offer payment plans between 6 and 24 months, and suspend service disconnections and late payment fees for customers. These directives will remain in place until the Governor determines that the economic and public health conditions have improved such that the prohibition does not need to be in place, or until at least 60 days after such declared state of emergency ends, whichever is sooner.
