The Puerto Rico Electric Power Authority (PREPA) is installing 464 megawatts of fuel-efficient, combined-cycle power generation in its existing steam plant near San Juan. The addition will increase output by more than 100 percent for a total combined output of 864 megawatts. After a false start with another engineering company, PREPA contracted with URS’ wholly owned subsidiary, Washington Engineers PSC (WEPSC).
Phase I of the contract called for an analysis of previous engineering work, as well as assessment of equipment that had been purchased for the project. In addition, the contract called for completing the balance-of-plant engineering and procurement, and providing construction/startup services for the repowering the project. Phase II of the project is the continuation and completion of the total engineering, procurement, and construction of Units 5 and 6.
Challenges included installing equipment in areas where existing foundations and underground electrical conduits and drainage tunnels were set 50 years earlier during the original project design. URS worked with various suppliers to expedite validating equipment that has been dormant and in storage for six years.
The plant was designed to operate on light distillate oil (LDO) with spatial consideration for a possible future conversion to dual fuel with the addition of natural gas firing capabilities.
