Siemens turbines to power 670MW combined cycle plant in Indiana

Siemens will supply F-class gas turbines and other equipment for a new 670MW natural gas-fired combined cycle power plant (CCPP) in the US state of Indiana. The proposed CCPP will be built in St. Joseph County by US-based Kiewit Power Constructors.

Siemens will supply two SGT6-5000F gas turbines, one SST6-5000 steam turbine and three SGen-1000A generators for the CCPP. The gas turbines and generators will be manufactured at Siemens' Charlotte Energy Hub.

SGT6-5000F gas turbine is said to offer economical power generation with fast start-up for peak, intermediate, or base-load duty. The SST-5000 series with a combined high-pressure / intermediate-pressure reverse-flow cylinder and a double-flow low-pressure cylinder enables a power output ranging between 120MW and 750MW, the company said.

Designed to meet the requirements of steam and gas turbines, SGen-1000A generator features air-cooled generators with a power rating between 165MVA and 350MVA.

Siemens Financial Services is providing $50m towards construction of the plant, which is expected to begin operations in early 2018. The power generated at the plant is likely to serve the electricity needs of more than 450,000 households.

Under a 25-year long-term services agreement, Siemens will provide advanced remote monitoring services along with programme parts, hardware, scheduled outage services and programme management for the project.
