Real-time monitoring of these factors is especially important when steam plants are operating in grid demand mode, re- quiring them to ramp-up generation faster and more often than they were originally designed to do. Without effective moni- toring and control of key plant processes, fuel consumption is inefficient, emissions increase, and equipment life may be im- pacted. "The only way we can do both is by applying data science and intelligent soft- ware-defined automation to every aspect of the electricity value chain, from gener- ation to delivery and consumption," said Ganesh Bell, chief digital officer, GE Power. "This announcement marks another big step on that journey." For example, Digital Power Plant software monitors and seeks to optimize the mix of fuel and air in the combustion process, which is critical to both output and emissions. Too much fuel in the mix may lead to higher emissions. Too little air may lead to ineffective combustion and output. The Digital Power Plant software ap- plications operate on Predix, which has seven important capabilities, including: Asset Performance Management for the Digital Steam Plant — An application that continuously monitors steam plant equip- ment health, enabling operations teams to make decisions that enhance plant perfor- mance, reduce unplanned downtime, and extend plant life with minimal capital in- vestment. Operations Optimization for the Digi- tal Steam Plant — An application that pro- vides customers with plant and fleet-wide visibility of the impact of operational de- cisions on efficiency, emissions, capacity and production costs. Boiler Optimization — Boiler efficien- cy has the greatest impact on overall plant efficiency. GE's software improves boiler reliability and efficiency, and can reduce CO 2 by 1-2% and NOx by 10-15% through integrated enhancement of the combus- tion and soot cleaning processes. Coal Analyzer — Enhances plant per- formance by tuning combustion and ex- haust management processes based on coal properties such as moisture content. This can reduce fuel consumption by 4,400 tons of coal per year with the same MW of output in a single steam power plant. Plant Optimization — A "digital twin" of the physical steam plant that is continu- ously monitored to identify gaps between actual and ideal performance relative to key performance indicators such as output or emissions. For example, tuning a plant to run 1% more efficiently can add $20 mil- lion in value over 10 years. Smart Start — Reduces inefficiencies that occur on load change by helping the operator improve key parameters includ- ing speed to grid, impact to asset life and fuel consumption. Business Optimization for the Digital Steam Plant — An application that aggre- gates information such as fuel and power price, demand, and plant capacity. GE Power is a world leader in power generation with deep domain expertise to help customers deliver electricity from a wide spectrum of fuel sources. They be- lieve the Digital Power Plant software can enhance the performance and reduce emissions of almost all steam plants com- missioned in the past 25 years.
