New York regulators in April approved construction of a 20-MW energy storage system at the site of an operating coal-fired power station near Union, Broome County. When operational, the $22.3 million project, owned by AES ES Westover LLC—an AES Corp. subsidiary—will use the technology to participate in New York’s growing day-ahead market for ancillary services and regulation.

Austin Energy replaced the selective catalytic reduction (SCR) catalyst twice over five years for its four peaker turbines. The duct modifications and injection grid redesign, combined with new catalyst, are producing high NOx reduction and low ammonia slip, and the catalyst is now expected to last at least five years.

In an unusual two-option proposal that drew clashing views from green groups and power plant operators, the Environmental Protection Agency has proposed regulating coal combustion ash either as a nonhazardous waste subject to tougher management and disposal requirements or as a "special" hazardous waste that would have similar controls but still be eligible for recycling and reuse in products such as Portland cement.

After more than a decade of debate, in April, U.S. Interior Secretary Ken Salazar approved Cape Wind, a proposed 130-turbine offshore wind farm for Nantucket Sound in Massachusetts. It would be the first wind facility in U.S. waters. Despite remaining hurdles, the approval marks a shift in political winds for the nation’s fledgling industry, and it could spur further development of projects proposed for relatively shallow waters along the East Coast and in the Great Lakes.

Gas turbines require clean gas to operate efficiently. Particulate contamination fouls fuel nozzles, causes increases in flue stack emissions, and occasionally causes unplanned plant outages. Now a new real-time natural gas cleanliness monitoring and web-based alarm system is providing valuable protection for natural gas–fired power plants. The adaptation of laser light–scattering technology for the purpose of contaminant measurement in high-pressure gaseous pipelines provides a method of monitoring liquid and solid contamination levels.

By Kennedy Maize Washington, D.C., May 26, 2010 — A breathless article in today’s New York Times outlines ties between U.S. Energy Secretary Steven Chu and, today’s chief villain, British Petroleum. Turns out that BP dropped half-a-billion dollars on Lawrence Berkeley Laboratory for work on alternative fuels when Chu ran the lab. When he got […]

Renewables will be the fastest-growing source of energy throughout the world over the next 28 years, helping to meet a projected 49% increase in world energy use, according to the U.S. Energy Information Administration (EIA). But, the agency also found in its International Energy Outlook 2010 released on Tuesday that fossil fuels could meet more than three-fourths of total energy needs in 2035, if current policies remain unchanged.

The U.S. Energy Department last week offered French firm AREVA a conditional $2 billion loan guarantee to facilitate financing of a uranium enrichment facility planned for development near Idaho Falls, Idaho.

The Tennessee Valley Authority (TVA) on Monday said completing one of two unfinished units at the Bellefonte Nuclear Plant in north Alabama would be preferred over building a new Westinghouse AP1000 reactor there, or taking no action.

New Jersey’s largest utility, Public Service Enterprise Group (PSEG) on Tuesday filed an Early Site Permit (ESP) application with the U.S. Nuclear Regulatory Commission (NRC) for a possible nuclear power plant adjacent to the company’s Salem and Hope Creek Generating Stations in that state.
