one of the largest electric generation and transmission cooperatives in the united states, Basin Electric Power cooperative (Basin Electric), generates and transmits electricity throughout nine states to more than 2.6 million consumers. Headquartered in Bismarck, north Dakota, Basin Electric is a consumer-owned, regional power supplier formed in 1961 to provide supplemental power to member electric distribution cooperatives.

named one of Power magazine’s top Plants for 2007, the Groton Generation station in Groton, south Dakota, is the newest peaking station to join the Basin Electric family and is home to the first commercial application of GE Energy’s lms100 gas turbine.

Adopting gE tEchnology in 2002, before the lms100 gas turbine simple-cycle power plant was constructed, Basin Electric determined that it would soon face a higher demand for power than its current generation capacity would support. Projected loads were growing at a rate that would leave them with insufficient capacity to satisfy the coming winter and summer peak loads. the lms100 gas turbine for its Groton power plant was a natural choice for Basin Electric because it offered operationally flexible power generation. GE’s lms100 gas turbine also provided a single, economical solution for dispatching power to the grid for a variety of grid demand scenarios. the lms100 gas turbine’s reliable 10-minute start time and premium thermal efficiency were key advantages for Basin Electric.

in January 2007, Basin Electric announced its intention to install a second lms100 gas turbine at the Groton Generation station. this second order was built on the success of the first lms100 gas turbine installation and Basin Electric’s confidence in GE’s technology and service. Groton went into commercial operation with unit 1 on July 1, 2006, and unit 2 on July 1, 2008.

the lms100 gas turbine’s control system is distributed between the turbine control panel and the remote i/o modules. local and remote i/o modules are interconnected with redundant fiber optics, and cables run from controllers to remote i/o modules that are mounted on the turbine base. this system reduced the number of signal interconnects by 90 percent and the number of mechanical interconnects by 25 percent, which yielded a simpler and more reliable design with faster, more efficient installation and startup.

utilizing a single system eliminates the coordination of the turbine and plant controls with which an Engineering Procurement contractor typically deals. the single control system shortened the engineering cycle, reduced potential startup and commissioning issues, and improved the coordination between the turbine, generator, and balance of plant controls.

the single control platform provides a number of plant personnel benefits. operators are able to see the complete plant on the operator workstations with easy navigation between turbine and BoP equipment screens. a single system provides for one plant-wide alarm management system. the mark vie toolboxst* provides a common set of configuration and diagnostic tools that are applicable across the turbine and balance of plant control. the common, time-coherent database simplifies system configuration and provides quality data for plant operations and diagnostic analysis. all digital points can be time stamped to +/- one millisecond for sequence of events. troubleshooting becomes much easier with the powerful trending and data analysis tools coupled with a single plant-wide data source. maintaining an inventory of spare parts for two different systems and training on two different systems is avoided with the common hardware and software control platform.

About thE MArk Vie icsthe mark vie ics is one of GE Energy’s most advanced control platforms, offering improved plant performance, operability, and availability. this scalable control system is available for a wide range of applications from wind, gas and steam turbines, to complete power plant controls, including simple-cycle, combined-cycle, integrated gasification combined-cycle and integrated water and power plants.
