provide a tremendous amount of flexibility
for customers with peaking needs and those
who want to participate in the ancillary
markets.

Adams: Fast-start capabilities need to be coupled with expectations of parts durability, reliability and reduced fall out. They also affect the base load efficiency due to increased clearances. Very aggressive

startup and loading ramps can negatively affect repair and maintenance costs, not to mention that excessive thermal and dynamic loading can cause catastrophic failure with the associated forced outages. Our upgraded designs have incorporated modifications that allow a conservative increase in acceleration and faster load rates. This faster startup and loading capability, coupled with high startup reliability, produces reliable reserve margins.

Boyce: Siemens is able to meet the need
for fast-start gas turbines utilizing our full

load Berlin (Germany) test bed to achieve breakthrough advancements in the existing SGT6-5000F technology with fast-start capabilities. This means 150 MW in 10 minutes without imposing a maintenance impact for the start. The Berlin test bed is a unique tool that allows validation of new technologies. The test bed is not connected to the grid but can be run at full power using a large water brake. Therefore, the facility is also used to evaluate the impacts of non-standard operation. Siemens then took the fast-start technology a step farther by putting this proven technology into combined cycle application, allowing the plant to produce more power faster, meet environmental compliances sooner, reduce startup emissions and reduce overall plant costs.

Our SCC6-5000F 2x1 Flex-Plant 30 is a highly efficient ( 57+ percent net) 590 MW plant, which can be started in half the time of a traditional F-class plant. The SCC6-5000F 1x1 Flex-Plant 10 is a 275 MW plant with 48 percent net efficiency that can generate 150 MW within 10 minutes. So whether a customer is looking for simple cycle or combined cycle power plants, Siemens has been able to create a product to meet their need using proven technologies.

PE: How have emerging markets for capacity payments and ancillary services to cope with narrowing reserve margins affected the products you sell?

Fukumoto: These new markets have led us to really focus on turndown capabilities, faster start-up options and operational flexibility enhancements. Customers who may have previously focused solely on efficiency may now have additional requirements. The key for us is to understand the particular needs of each customer and project and help them choose the best capabilities to meet their needs.

Our focus is to allow customers to play in all ancillary markets without sacrificing performance or costs. As I previously noted, we enhanced our 7FA gas turbine to play in all markets very effectively.

Ancillary services are key financial tools to drive market competition and encourage proper siting of new generation for transmission relief as well as capacity. The existing technology has the capability to meet these criteria, meaning fast start, regulation up and down and VAR support, with simple attention to modifying controls for regional needs.
