In December 2006, NRG initiated a $100 million emergency re-powering project to restore the Long Beach Generating Station to commercial operation. The specific objective was to re-power four of seven combustion turbines, which had been idled since 1998, prior to August 1, 2007 in order to meet the summer peak generation period. The project was faced with many unique challenges, including:


MPR, as Project Engineer provided oversight of all engineering efforts for the re-powering project. MPR performed system evaluations, identified risks, and made recommendations to define the project scope. MPR led the design process to resolve all structural issues, modify gas compressor systems, and prepared the designs for the new cooling water system, combustion turbine generator inlet fogging, and distributed control systems. MPR also managed the budget and effectively managed costs by reuse of existing equipment when possible.


MPR delivered and enabled NRG to meet its promise to provide critical power to Southern California. The project was completed in 3.5 months and all project success criteria were satisfied including:

A heat wave hit Southern California in August 2007, after the plant commissioning, and peaking power was available when it was critically needed.
