PNM selects Sargent & Lundy for emissions reduction project

8 April 2005 – Sargent & Lundy has been awarded a contract by Public Service Company of New Mexico (PNM) to provide detailed engineering for the recently announced major air emissions reduction projects at the San Juan Generating Station (SJGS).

The engineering contract for the programme at the 1798 MW, coal-fired plant near Farmington, N.M. includes Mercury control technology on all four units to reduce mercury emissions. After initial evaluation of the performance of this technology on Units 3 and 4, PNM will install the technology on the plant’s remaining two units. New advanced low-nitrogen oxide (NOx) burners and overfire air on all four units will be fitted to reduce the NOx emissions rate by 35 per cent from the current permitted level. Baghouse control technology will be added on the plant’s four units to reduce the particulate matter emission rate by 70 per cent from the current permitted level. There will be additional sulphur dioxide (SO2) emissions reductions from increased scrubbing by enhancing the removal efficiency of the existing pollution control system to 90 per cent.

In addition to PNM, which operates the plant, SJGS is also owned by Tucson Electric Power, Southern California Public Power Authority, M-S-R Public Power Agency, Tri-State Generation & Transmission, City of Anaheim, Los Alamos County Utilities, City of Farmington, and Utah Associated Municipal Power Systems.

Engineering will begin immediately and the installations will be fully operational on all four units by January 2010. SJGS is one of the first coal-fired plants in the nation to make a voluntary investment in mercury emissions reduction technology, and PNM’s aggressive program will also make significant reductions in particulate matter, NOx, and SO2 emissions.

“All of us at Sargent & Lundy appreciate PNM’s confidence in our engineering and project management expertise in undertaking major air quality control programs,” said Bud Wendorf, Sargent & Lundy Chairman & CEO. Sargent & Lundy Senior Vice President Bob Herbster, who is directing the
engineering team for the SJGS effort, added ” We have assembled a veteran team, and we’re truly looking forward to working with PNM to make this showcase project highly successful.”
