Oak Grove is a pulverized coal plant fueled by lignite to utilize new activated carbon sorbent injection technology to remove mercury. Luminant said that Oak Grove unit 1, as well as unit 2 upon completion, will have lower emission rates.

Mike Williams, chief fossil officer of Luminant, said: “Achieving this critical step signals the end of construction and the beginning of Luminant’s operation of another significant source of baseload generation for Texas. Our operations team is fully engaged in the day-to-day management of the unit, which will generate needed electricity to help meet our state’s growing power demands.”

Oak Grove unit 2 is scheduled for completion in mid-2010. Combined, the plant will be capable of generating 1,600MW, enough to power approximately 850,000 average Texas homes.

Luminant, a subsidiary of Energy Future Holdings, is a power generation business, including mining, wholesale marketing and trading, construction and development operations.
