Carbon dioxide emissions aren’t yet regulated by the EPA, but it’s likely they will be soon. There are many technically feasible, but as-yet-undemonstrated ways to reduce the considerable carbon footprint of any coal-fired plant, whether it uses conventional or unconventional technology. One promising approach to removing CO2 from a plant’s flue gas uses chilled ammonium bicarbonate to drive the separation process.

The dearth of commercial operating experience for advanced coal-fired facilities is forcing their early adopters and builders to use long development cycles and pay high costs for unique engineering design studies. A broad-based industry collaborative effort fostered by EPRI to address this issue is beginning to show results.

POWER has reported on several EUCG benchmarking studies over the past several years. This month we examine the maintenance staffing of 45 coal plants reported by 13 EUCG member utilities. If you benchmark your plants or fleet, as you should, some of the study’s results challenge what is considered conventional wisdom.

All fossil fuels carry some risk with their reward of an energy density that’s sufficient for producing electricity economically. For coal and natural gas, that threat is a fire or explosion. However, the risk of an explosion isn’t limited to gas-fired plants. Gas poses a threat to any plant that uses the fuel, even in small quantities for heating. Here’s an overview of what you should be doing to keep gas pipelines from corroding and exploding.

Last year, San Diego Gas & Electric tapped Boston-based EnerNOC Inc. to aggregate 25 MW of backup generators throughout SDG&E’s service area to relieve the grid when it’s stressed by peak demand for electricity. By combining stringent environmental controls with field-proven expertise managing distributed assets, EnerNOC has helped to improve grid stability in Southern California.

Chances are good that legislation to “cap and auction” greenhouse gas (GHG) emissions will become law as early as 2009. While many environmentalists, utilities, and energy companies agree that cap and auction is the right framework, huge differences remain. Environmentalists want an 80% reduction of GHG emissions by 2050, or sooner. Energy companies want more […]

  Early last month, Governor Eliot Spitzer and Attorney General Andrew M. Cuomo—both New York Democrats—asked the U.S. Nuclear Regulatory Commission (NRC) to reject Entergy Nuclear’s application to extend the operating licenses of Indian Point Units 2 and 3 for 20 years. The units, each rated at about 1,000 MW, are a major source of […]

The U.S. Congress continues to debate proposals that would mandate that a set amount of the nation’s electricity come from renewable energy sources such as wind, the sun, or biomass. These discussions about adopting a nationwide renewable portfolio standard (RPS) raise significant concerns for power providers and customers alike. Backers of a one-size-fits-all federal RPS […]
