Better accuracy, more consistency and greater flexibility to adapt
In an effort to streamline and automate operations at its plants, CPV adopted GE Digital’s Operations Performance Management (OPM) to create a ‘Digital Twin’ of critical processes. OPM analyzes historical data, plant operations and other data sources to monitor and identify areas of improvement, predict capacity to improve day ahead and intraday planning, deliver executable advice and drive desired outcomes including improved capacity.
By creating a Digital Twin of critical plant processes, energy traders, asset and plant managers can better understand the day-ahead and potential plant capacity, as well as how to make the most profitable use of that capacity through commitment preparation, fuel nomination and dispatch planning. OPM Production Planning leverages machine learning to derive a more accurate predictor of capacity and allows CPV to maximize their ability to offer the most MWs in the Day Ahead market and not expose them to real-time market pricing if the forecast is off. This helps CPV to increase their Day Ahead revenues. It also provides more accurate performance predictions because it includes the use of barometric pressure, which has a direct effect on power output and was not easy to bring into the Excel calculation. Unlike the previous Excel models, the OPM solution is reliable, consistent and adaptable - automatically adjusting to weather formats as they change and providing configurable reports tailored to the needs of different energy managers for plants in different ISOs. Furthermore, with GE Digital's OPM software, the operators no longer need to worry about sending out the report and can focus on their time where it is needed most – reliably operating the plant.
Additionally, with OPM and leveraging GE’s Digital Twin and Advanced Controls technology, the Capacity Dispatch Optimizer banks energy credits when the plant runs at part load by reducing gas turbine firing temperatures, while maintaining the same output. The banked credits are used to offset the effects of peak fire and therefore do not impact the maintenance interval or costs. This allows CPV to deliver extra capacity when the marketplace needs it most, without having to incur additional maintenance costs or worry about the maintenance interval changing and falling in a peak operating season. With CPV’s invested and continual deployment of cutting-edge technology, such as OPM, their operations are propelling to the forefront of the competitive power industry.
