(credit: Matt Hintsa) Today, US Energy Secretary Rick Perry directed the nation’s federal grid regulator to create rules favoring coal, hydroelectric, and nuclear generators. The Notice of Proposed Rulemaking (NOPR) (PDF) stated that the Federal Energy Regulatory Council (FERC) must order grid operators to increase how they value “reliability and resilience attributes” in energy generation. Although no specific electricity sources were mentioned as beneficiaries of the rule, generating units that can hold a 90-day supply of fuel on site would be favored.
