Hitachi Power Systems America (HPSA) was awarded a contract for the design and supply of a selective catalytic reduction (SCR) system with Tri-State Generation and Transmission Association for its Craig Generation Station, Unit 2, located in Craig, Colorado. The contract includes the design and supply of a SCR System for Craig Unit 2 which is a coal-fired steam electric generating unit with a net capacity of approximately 428 MW.
Selective catalytic reduction
NRG Energy began commercial operation at its Marsh Landing Generating Station, a 720-MW natural gas–fueled, peaking facility located near Antioch, Calif., in the San Francisco Bay area. The Marsh Landing station will employ technologies to meet or exceed the state of California’s standards for emissions control and air quality. The turbines will operate with ultra-low nitrogen oxides (NOx) combustors, along with selective catalytic reduction (SCR) and an oxidation catalyst system to reduce carbon monoxide and other organic compound emissions.
MATS compliance now, with flexibility for the future.
Conflicting demands for complying with EPA’s MATS rule favor a single control technology to deal with multiple types of power plant emissions.
2011 Groundbreaking Law & Lawyers Survey and Report
With a flurry of major new environmental regulations, the Environmental Protection Agency (EPA) is altering the power generation landscape. But will the new federal rules survive court challenges—to say nothing of next year’s national elections? Fortnightly's Michael T. Burr considers the controversy over new environmental standards. PLUS: Top Utility Lawyers of 2011.
THE U.S. ENVIRONMENTAL PROTECTION AGENCY HAD A novel idea: For power plants and sources relying on devices to control air emissions, rather than attempt to monitor the actual physical emissions to determine compliance with federal law, it simply would require inspections and tests of the performance of the control device. %n1%n
This strategy was formalized in the EPA's compliance assurance monitoring (CAM) rule signed Oct. 17, 1997. The EPA's theory is that if the control device is working properly, it is likely pollutant emissions fall within the required limits.
