To counter generator-announced plans to retire nearly 14,000 MW of generation between May 2012 and the end of 2015 and boost reliability, the PJM Interconnection Board last week approved nearly $2 billion in transmission upgrades.

An explosion on Sunday night at a coal bunker at DTE Energy’s St. Clair Power Plant in Michigan left one worker with a minor injury and caused minor damage to the plant. The cause of the explosion is under investigation.

Finding in a preliminary determination that crystalline silicon photovoltaic (PV) cells are being sold in the U.S. at below-market prices that harm domestic manufacturers, the Commerce Department slapped a 31% tariff on 61 Chinese PV producers and exporters with slight variations by company. All other Chinese producers and exporters of the cells will be subject to a tariff of nearly 250%. The decision has incited mixed, heated reactions from the solar industry.

Compliance with the Environmental Protection Agency’s (EPA’s) Mercury and Air Toxics Standard (MATS) by April 2015 will require coal generators in the Midwest to install retrofits at a pace and scale that exceeds “historical demonstrated capability,” and it will impose taxing bottlenecks on the nation’s power sector labor, equipment, and supply chain, a new study suggests.

A new report shows that the reserve margin for the Electric Reliability Council of Texas (ERCOT) could plunge to 9.8% as soon as 2014, to 6.9% in 2015, and to a negative margin by 2022—well below the grid operator’s 13.75% target for electric generation capacity that exceeds the forecast peak demand on the grid.

Nuclear Regulatory Commission (NRC) Chair Gregory Jaczko on Monday announced his resignation after more than seven years as a member and three years as head of the federal regulatory body. But Senate Majority Leader Harry Reid (D-Nev.) last week suggested that Jaczko could be re-nominated if a successor is not confirmed by June 20, 2013, when the chairman’s first term ends.

The long-awaited restart of Bruce Power’s Unit 2 at Bruce A on Friday was delayed again for months after an issue was identified within the electrical generator on the non-nuclear side of the Ontario plant just an hour before synchronization with the grid was scheduled to occur.

Japan’s trade minister last week approved a ¥1 trillion ($12.5 billion) capital injection to avert the collapse of the Tokyo Electric Power Co. (TEPCO). The move is effectively a nationalization of Japan’s largest utility and owner of the crisis-stricken Fukushima Daiichi nuclear plant.

Citing the need for local and regional transmission reliability and affordability, Wisconsin’s Public Service Commission (PSC) last week voted to grant a Certificate of Public Convenience and Necessity for an approximately 48-mile 345 kV electric transmission line between Alma, Wis., and Holmen, Wis., that is part of the $2 billion CapX2020 initiative.
