Generating power from fossil fuels will continue to be the norm for the time being, as transitioning to renewable energy sources is a complicated process.
FREMONT, CA: Even before COVID-19, renewable energy sources, low gas prices, and ambitious decarbonization targets, all of which are shifting customer preferences, were causing substantial disruption to fossil-fuel power plants. Adopting the newest digital and advanced analytics technology has become crucial as the power-generation industry moves to the next normal.
Several power firms started their digital transitions with data models, which help optimize set points, improve dispatch decisions, and support maintenance plans and operating-mode choices.

Many forward-thinking businesses have recently begun to use visualization tools to monitor real-time generation performance and digital control software to send predictive data to control rooms. But as these advances are based on tangibly enhancing plant operations, they are only a portion of a digitally enabled, next-generation power plant.
The foundation for digital tools has rapidly expanded
Power plants have traditionally depended on well-established legacy systems focused on "first principles" engineering insights and problem-solving methodologies, like direct temperature or pressure deviation monitoring, without using predictive or pattern-recognition algorithms. These projects needed the acquisition of costly systems that only recorded a few kinds of data and depended on proprietary engineering knowledge to offer system warnings and operating bands.
Two trends point the energy companies in the right direction. First, operators have better understood new data collection and storage technologies, processes, and tools. As a result, rudimentary dashboards have been developed to monitor plant-specific parameters like high super heater temperature alarms or excessive pressure on a turbine.
Second, as data-processing costs have been reduced, the accessibility of employees trained in programming and digital technologies has increased. As a result, there are now more companies offering low-cost data analytics solutions.
Small software programs designed to improve a single operation or support a constant decision point have multiplied. Increasing specification levels have established a technology ecosystem that enables power producers to adopt targeted value-adding digitization.
Next-generation tools can be quickly adopted
Power plants are already extensively "sensorized," which means they continuously collect and store large volumes of data. But according to research, only 20 to 30 percent of the data gathered is used to directly impact decision-making, and the data from the sensor can be better optimized.
This informational foundation will most probably be the groundwork for the next generation of value. To uncover unique data predictors of plant performance, operators might use an analytics-based strategy. By combining those results with first-principles engineering and, operational insights can optimize the unknown value drivers. Rapid machine-learning algorithms, for example, can already determine the best settings for increasing combined-cycle gas turbine plant outputs and heat rates.
