Martin Lake
Location: TX
Operator: Luminant Power Co LLC
Configuration: 3 X 793 MW
Fuel: lignite, subbituminous coal
Operation: 1977-1979
Boiler supplier: CE
T/G supplier: WH
EPC: CT Main, Zachry
Quick facts: At completion, this was one of the largest lignite-fired power stations in the world. A fourth unit was in the original design but never built. An electric train delivers lignite from nearby mining areas and the plant also receives rail shipments of PRB coal. Martin Lake’s three supercritical units have Research Cottrell wet limestone FGD scrubbers and low-Nox burners. The power station uses a 5,000ac cooling reservoir, which is a popular site for fishing and recreation. TXU made 200ac of the site available to the state for creation of the Martin Creek Lake State Park, which opened in 1976.

Monticello
Location: TX
Operator: Luminant Power Co LLC
Configuration: 2 X 590 MW, 1 X 790 MW
Fuel: lignite, subbituminous coal
Operation: 1974-1978
Boiler supplier: CE, B&W
T/G supplier: WH, GE
EPC: Ebasco, CT Main, Brown & Root
Quick facts: For 20yrs after completion, Monticello exclusively burned local lignite, its design fuel. In 1995, plant management began blending PRB coal into the fuel mix and it now accounts for 50% of Monticello's total fuel tonnage, or about 6mn tons in 2005. The plant has made numerous modifications to its fuel delivery, handing and storage systems to safely and efficiently use PRB coal. Monticello was named one of Power magazine's Top Plants of 2006. In Dec 2008, the plant completed a 16yr, 9mn manhour streak without a single-lost-time injury, a utility record. All three units are supercritical.
