An Environmental Protection Agency proposal to tighten sulfur dioxide and nitrogen oxides limits in 31 states and the District of Columbia to address transported air pollution fails to give utilities and state air regulators sufficient time to develop rules and install controls, according to American Electric Power Co. Officials from the EPA and New Jersey-based Public Service Enterprise Group said utilities already had begun making investments to cut emissions and they believed the agency’s compliance schedule could be met.

Many claim that wind generation is beneficial because it reduces pollution emissions and does not emit carbon dioxide. This isn’t necessarily the case. When wind is introduced into a generation system that uses carbon technologies to back up the wind, it actually reduces the energy efficiency of the carbon technologies.

Every power engineer must have a firm grasp of the rudiments of how fuel is processed to produce electricity in a power generation facility. With this article, we conclude our three-part series on the essentials of recovering heat from flue gas to dry and process coal, with the goal of improving overall plant operating efficiency.

Progress Energy has incorporated online combustion optimization/tuning to eliminate furnace reducing atmospheres at its Asheville Plant. The optimization project utilized individual burner airflow measurement and continuous burner coal flow measurement to adjust burner air/fuel ratios. The result: significantly improved boiler combustion.

The EPA, determined to regulate U.S. carbon dioxide emissions under the Clean Air Act, found that the low limits set by the Act for any “regulated pollutant” led to, in the EPA’s words, “absurd” results. Undeterred, the EPA developed the “Tailoring Rule,” which reinterprets the Act to apply to only larger emissions sources. Texas eloquently rejected the EPA’s legal gymnastics.

California, New Mexico, and three Canadian provinces—partners of the Western Climate Initiative (WCI)—last week released a detailed plan for a regional cap-and-trade program to curb greenhouse gases (GHG) starting in January 2012. If the plan reaches fruition, it would be three times larger than a program under way in 10 eastern states.

Hawaii’s Public Utilities Commission (PUC) last week denied a request by Hawaiian Electric Co. (HECO) to extend pilot testing for its advanced metering infrastructure (AMI) project to 5,000 more smart meter because of cost concerns. The move poses a major hurdle for the utility’s overall smart grid initiative.

Only 700 MW of wind power were added in the U.S. during the second quarter of 2010—a drop of 57% and 71% when compared to second quarter numbers from 2008 and 2009, respectively, the American Wind Energy Association (AWEA) reported last week.

New York state and Pennsylvania’s Department of Environmental Protection (PADEP) plan to sue Homer City Station, a 1,884-MW coal-fired power plant in Pennsylvania, for its alleged contributions of the region’s sulfur dioxide emissions.

The Department of Energy last week finalized a $117 million loan guarantee for a 30-MW Hawaiian wind power plant, and this week it said it would offer a $17.1 million loan guarantee to support construction of a 20-MW energy storage system using lithium-ion batteries.
