To counteract the effects of such situations, the Secretary’s office suggested to strengthen power plants with fuel on site, that is coal and nuclear plants. To do so, the department issued a Notice of Proposed Rulemaking which requested that FERC require utility companies to pay not just for the electricity they buy from power plant companies and supply to consumers, but also for the fixed costs associated with power plants that keep 90 days of fuel on site.

However, the Regulatory Commission said that Perry’s arguments were unfounded. “There is no evidence in the record to suggest that temporarily delaying the retirement of uncompetitive coal and nuclear generators would meaningfully improve the resilience of the grid. Rather, the record demonstrates that, if a threat to grid resilience exists, the threat lies mostly with the transmission and distribution systems, where virtually all significant disruptions occur. It is, after all, those systems that have faced the most significant challenges during extreme weather events,” today’s decision reads.

Nevertheless, the five-member bureau said it will review the resilience of the nation’s electric grid by assessing information that should be provided within 60 days by each regional market operator and other entities that oversee the grid. Once that documentation is processed, the panel will decide whether it’ll implement new measures.

According to AP, Perry thanked the federal agency for addressing his proposal. “What is not debatable is that a diverse fuel supply, especially with onsite fuel capability, plays an essential role in providing Americans with reliable, resilient and affordable electricity, particularly in times of weather-related stress like we are seeing now,” AP quotes him as saying.

Environmental advocates, business groups, some public utility companies, as well as natural gas suppliers such as Koch Industries had previously criticized the Secretary’s proposal saying it would raise prices and disrupt electricity markets by subsidizing coal and nuclear plants with billions of dollars.
