Coal Whelan Energy Center 2 Conducts Testing in Preparation for Commissioning

---

Researched by Industrial Info Resources (Sugar Land, Texas)--Public Power Generation Agency (Hastings, Nebraska) was created by four utilities in Nebraska and one in South Dakota to build a 220-megawatt (MW) coal-fired subcritical unit. The utilities involved are:

• Municipal Agency of Nebraska (Lincoln, Nebraska): 80 MW (36.36%)
• Heartland Consumers Power District (Madison, South Dakota): 80 MW (36.36%)
• Hastings Utilities (Hastings): 35 MW (15.91%)
• Grand Island Utilities (Grand Island, Nebraska): 15 MW (6.82%)
• Nebraska City Utilities (Nebraska City, Nebraska): 10 MW (4.55%)

The new unit is being built at the existing 77-MW Gerald T. Whelan Energy Center in Hastings and will be operated by Hastings City Utilities. The new unit is scheduled for completion in February 2011 and will use the existing control room, coal-handling equipment and ash-disposal pond.

Engineering and procurement was overseen by Black & Veatch (Overland Park, Kansas). The construction was performed by multiple contractors. The 220-MW steam turbine was provided by Toshiba Corporation (TYO:6502) (Tokyo, Japan). The boiler was engineered by Babcock & Wilcox (Barberton, Ohio) and fabricated by Babcock & Wilcox Beijing Company Limited (Beijing, China)--both part of McDermott International Incorporated (Houston, Texas) (NYSE:MDR).

Allied Environmental Solutions Incorporated (Columbia, Maryland), a subsidiary of EnviroTherm GmbH (Essen, Germany), itself a joint venture of Allied Resources Corporation (Warren, Pennsylvania) (70%) and Aloe Investment Fund (Paris, France) (30%), supplied the air-quality equipment. The equipment consists of a circulating fluidized bed (CFB) scrubber, a pulse-jet fabric filter baghouse with an activated carbon injection system, and a scalping electrostatic precipitator for ash sales.

The water treatment system for the project is being provided by Eco-Tec Incorporated (Pickering, Ontario). This will consist of integrated water treatment components to include two trains of Double-Pass Eco-RO™ and Recoflo® polishers, which will result in a demineralized water quality of less than 0.1 µS/cm.
