Chalking up cleaner air

The Shaw Group’s Fossil Division has signed an engineering, procurement and construction contract with Mirant Mid-Atlantic and Mirant Chalk Point to fit emission controls at three Maryland power plants.

The $1.1bn contract covers the retrofit of new emission controls, which will include flue gas desulphurisation units, for Mirant’s Chalk Point, Morgantown and Dickerson coal-fired power plants.

The retrofit program is expected to finish in December 2009, and finalises an alliance agreement signed in July last year.

Atlanta-based Mirant produces and sells electricity in the US and the Caribbean.
