Nebraska City II Power Plant Expansion
When Omaha Public Power District (OPPD) built a power plant on the banks of the Missouri River in the 1970s, hundreds of contracts were issued. More than 30 years later, the utility completed a new, 663 megawatt, $630-million plant adjacent to the original plant, the project was completed with a single engineering, procurement and construction (EPC) contract. As Owner's Engineer for the project, we helped OPPD save time and build a bigger facility, yet keep capital costs at $950 per kilowatt below original budget projections. OPPD originally contracted for 663 MW, but recent performance tests have shown the unit capable of producing 682 MW.
The EPC contract helped OPPD manage project risk, resulting in a well-defined scope that accurately represented the owner's desires. Early permitting attracted a number of capable contractors, and preliminary engineering and procurement documents articulated a clear plan, helped ease doubts and encouraged subcontractors to submit bids. Delivering under budget allowed OPPD to pass savings onto customers with no need to raise rates to cover construction costs. Running on clean-burning Powder River Basin coal from Wyoming, the new plant will supply distributors in four states. Its emissions controls - scrubbers, baghouse filters - will control acids, mercury levels and particulates while a selective catalytic reduction system make the plant cleanest coal-burning facility operated by OPPD.
