PPL Corp.’s Susquehanna nuclear power plant in Luzerne County, Pa., is the nation’s largest boiling water reactor (BWR) in terms of thermal power and generating capacity, according to the Nuclear Regulatory Commission (NRC). The plant’s Unit 1, which recently completed equipment and system upgrades during a recent scheduled refueling and maintenance outage, boasts 3,952 MWth and 1,300 MWe when operating at full capacity.

A new rule for sulfur dioxide (SO₂) set by the Environmental Protection Agency (EPA) on Thursday sets a new one-hour health standard, changes monitoring requirements, and modifies the Air Quality Index. Full implementation of revised primary National Ambient Air Quality Standard (NAAQS) for SO₂ by 2020 could cost the electric power industry nearly $700 million a year, the agency said.

By Kennedy Maize Washington, D.C., 6 June 2010 — I’m offering a challenge and opportunity to those of you who believe that the science of global warming is settled: take a look at an informed contrary view.

Southwestern Electric Power Co. (SWEPCO) and the Arkansas Public Service Commission (APSC) on Tuesday asked the Arkansas Supreme Court for a rehearing, after the high court last month overturned a 2007 permit awarded by the PSC to the utility’s 600-MW John W. Turk, Jr. power plant. SWEPCO said that it plans to continue construction of the $1.7 billion project—the nation’s first ultrasupercritical coal plant—to meet its commitments to serve the company’s customers in three states.

CMS Energy subsidiary Consumers Energy last week announced that it is deferring the development of an 830-MW coal-fired power plant planned for Hampton Township. State regulators had last year approved an air permit for the $2 billion-plus project on the condition that it use stringent emission controls and that it was ready for carbon capture and sequestration when the technology was feasible.

Mississippi Power Co. on Thursday said it would proceed with plans to build a 582-MW integrated gasification combined cycle (IGCC) plant as proposed in Kemper County after the Mississippi Public Service Commission (MPSC) relaxed restrictions it had placed on the project.

The U.S. Court of Appeals for the Fifth Circuit on Friday dismissed without rehearing, on procedural grounds, a controversial climate change “public nuisance” case in which 14 individuals had filed a class-action lawsuit against insurance, coal, and chemical companies, seeking relief for property damages resulting from Hurricane Katrina.

Depressed power demand due to a slow economic recovery will continue to be a major driver affecting bulk power system reliability during the summer months, the North American Reliability Corp. (NERC) said last week in its annual summer reliability assessment report.

Tokyo Electric Power Co.’s new Kawasaki Thermal Power Plant claims the title of having the highest combined-cycle efficiency in the world: 59.1%. The new gas-fired facility is equipped with three 500-MW single-shaft combined-cycle blocks. Each block is based on the MHI M701G2 gas turbine, which is the largest gas turbine currently in commercial operation.
