Project Owner:
Sempra Energy Resources (formerly Texas-New Mexico Power)

Completion Date: 1991

Twin Oaks Power is a two-unit power generation facility that was originally built to meet a portion of Texas-New Mexico Power Company’s projected power needs for its service territory.

The facility consists of two 165 MW, lignite coal-fueled units. At the time of initial operation, the plant had the two largest circulating fluidized bed combustion technology steam generators in operation in the world. The lignite fuel for the facility comes from an adjacent mine. Twin Oaks Power fully complies with permitted environmental standards regarding sulfur dioxide and particulate emissions.

It serves as a base-loaded source of power for the utility and was completed per the established schedule and budget. Utility Engineering (UE), serving the consortium that built the facility for the owner, was responsible for the balance of plant engineering, checkout support and performance testing.

Services Performed:

• Plant layout and estimating
• Detailed BOP engineering
• Checkout, start-up and training
• Performance testing
• Life cycle costing
• As-built documentation
