Contract for Whelan Energy Center Unit 2 automation and control system continues Emerson’s longstanding relationship with Hastings Utilities
PITTSBURGH, PA (January 16, 2008) —Emerson Process Management announced today that it has won a contract to install its PlantWeb® digital plant architecture with the Ovation® expert control system at Whelan Energy Center Unit 2 (WEC 2), a new 220-MW coal-fired unit being constructed near Hastings, Neb.
WEC 2 will be owned by the Public Power Generation Agency (PPGA) which consists of five public power entities: Grand Island Utilities, Hastings Utilities, Heartland Consumers Power District, Municipal Energy Agency of Nebraska (MEAN), and Nebraska City Utilities. Black & Veatch Corp. is the engineering firm for the project. The new unit, expected to begin commercial operation in 2011, is being built at the site of Whelan Energy Center, an existing 77-MW coal-fired plant that has been in service since 1981.
"Nebraska and the Midwest region are facing an increased demand for electricity,” said Allen Meyer, PPGA project construction manager. “The additional megawatts produced by this plant will help PPGA member companies meet the needs of their customers and, therefore, have a positive impact on the region.
Emerson’s Ovation system will manage a total of 4,500 I/O points at WEC 2. The Ovation system will monitor and control the unit’s boiler, as well as the burner management system, flue gas desulfurization system and balance of plant processes. In addition to the Ovation system, Emerson will also provide AMS® Suite: Intelligent Device Manager, as well as 200 Rosemount 3051T pressure transmitters and 74 Rosemount 3051C differential pressure transmitters.
Emerson has a longstanding relationship with Hastings Utilities, which will operate WEC 2 on behalf of PPGA. Not only does the utility’s North Denver generating station also rely on Ovation technology, Emerson’s legacy 7300 controls were also the original controls for Whelan Unit 1. In fact, in a project completed in November 2007, Whelan Energy Center’s boiler and turbine controls were replaced with Emerson’s Ovation system. Aligning a unit’s boiler and turbine control is advantageous, translating into unit-wide compatibility; improved unit stability, responsiveness and thermal efficiencies; tighter overall control of plant operations; and a concise view of key plant and turbine parameters.
For Emerson, the WEC 2 contract further underscores the company’s leadership and experience in supplying automation and control solutions for new coal-fired plant construction.
"The Ovation system has been selected for 12 new North American coal-fired plant contracts in just the last 18 months, confirming that Emerson is the automation supplier of choice for the power industry,” said Bob Yeager, president of the Power & Water Solutions division at Emerson. “We’re gratified to count PPGA among the power producers that have placed their trust in Emerson control technologies for important new coal projects that will help satisfy the country’s growing demand for power.”
