DOE Set to Support Small Modular Coal Units

The U.S. Department of Energy (DOE) wants to know whether small-scale, modular coal-fired power plants are feasible. The DOE this week put out a request for information on how to accomplish such projects, following on its announcement earlier this year that it wants to establish funding opportunities for new coal technologies in an effort to […]

Sufficient Blackstart Capability Exists on Grid, Say NERC, FERC

  Despite the recent retirement of “blackstart” units, grid operators have sufficient resources to quickly restore systems in the event of widespread outages, suggests a new report by staff at the Federal Energy Regulatory Commission (FERC) and the North American Electric Reliability Corporation (NERC). The report—“FERC-NERC-Regional Entity Joint Review of Restoration and Recovery Plans”—released May […]

December 2000—Milledgeville, Ga.: About 35,000 gallons of wastewater laden with coal ash is released from Georgia Power’s Plant Branch into Lake Sinclair when a mechanical failure of an isolation valve causes water from an ash pond to be siphoned back and discharged through the cooling water tunnel system into the lake. Plant Branch has since been retired to meet environmental rules, though the EPA continues to scrutinize three of its five coal ash ponds, which have received a significant or high hazard rating.

PJM Says Grid Reliable, but Will Analyze Resilience

The operator of the nation’s largest electrical grid on April 30 reiterated its system will remain reliable even with the retirements of substantial generation resources. But PJM Interconnection, whose system covers customers in 13 states, said it will conduct a review of its operations over the next several months “to understand the fuel-supply risks in […]
