The Shaw Group Inc. has been awarded a contract to install equipment to reduce sulfur dioxide emissions from a 585-megawatt coal-fired power plant in northeastern Oregon.

Baton Rouge-based Shaw will engineer, procure and build the system for Portland General Electric’s Boardman Station. The contract’s value was not disclosed.

Power plants are developing strategies to comply with new air quality regulations at the state and federal level, said Andy Dupuy, president of the Fossil Division of Shaw’s Power Group. Shaw is seeing a trend in the use of dry sorbent injection, a relatively inexpensive process to reduce sulfur dioxide emissions for the short term.

The utility industry is expected to shut down anywhere from 30 gigawatts to 75 gigawatts of coal-fired power generation plants by 2016, depending on the speed at which federal pollution regulations are put into place. That is enough electricity to power 17.5 million to 43.8 million homes.
