Subsequent Events [Abstract] |
Subsequent Event | Subsequent Event On January 30, 2019, Consumers experienced a fire at the Ray Compressor Station, which resulted in the Ray Storage Field being off-line or operating at significantly reduced capacity, which negatively affected Consumers’ natural gas supply and delivery capacity. This incident, which occurred during the extreme polar vortex weather condition, required Consumers to request voluntary reductions in customer load, to implement contingency gas supply purchases, and to implement a curtailment of natural gas deliveries for industrial and large commercial customers pursuant to Consumers’ MPSC curtailment tariff. Consumers is investigating the incident. The curtailment and request for voluntary reductions of customer loads were canceled as of midnight, February 1. At this time, Consumers cannot predict the ultimate financial impact of the incident or other gas-related incidents, but they could have a material adverse effect on Consumers’ results of operations, financial condition, or liquidity, and could subject Consumers’ gas utility to increased regulatory scrutiny.
