Flex-Power Services

The global energy markets are changing and renewables are increasing, which leads to new operating profiles requiring higher operational flexibility for many fossil power plants. The higher flexibility is required to stabilize the grid and stay competitive by reducing costs. This leads to various customer requirements:

Increased number of annual starts
Fast ramp up and ramp down time
Maximum output in the reserve time

To help address these changing operational requirements, Siemens Energy has developed and continues to evolve the Advanced Operational Flexibility including Flex-Power Services™ and Omnivise Performance.

Start and Stop Performance

Products and solutions supporting Power on Demand are intended to enhance Start and Stop Performance and can include upgrades designed to:

decrease waiting times for water-steam cycle warm up
decrease or even eliminate holding times
increase ramp rates of ST and/or GT

A shortened start-up or shutdown time may not only increase flexibility, but also support a reduction of fuel consumption and associated emissions in these operating conditions.

Start Readiness & Cool Down

Advanced preservation concepts and the ability to maintain a plant in a status which allows fast re-start even after multiple days of shutdown may greatly enhance flexibility and support better dispatch success.

Reduced cool-down times may support faster access to components for inspections and repairs, thus supporting shorter outages.

Advanced inspection and interval concepts can help to safeguard and enhance availability.

Energy Management

Energy markets are becoming increasingly complex due to the influx of new generation assets like renewables, microgrids and the hybridization of traditional CCPPs with storage and other energy assets. All of which makes it more difficult for asset operators to quickly respond and optimize their generation.

Solutions that manage the distribution of generation are needed to economically optimize plant operations:

Dispatch optimization improving the energy management of your fleet through an optimized generation schedule
Hybrid controller integration responds rapidly and automated to generation adjustments

Emissions and Efficiency

In energy markets with a volatile infeed from various generation sources, combined cycle power plants may find themselves in situations where they need to improve and monitor efficiency and emissions for minimum, part and base load.

Upgrades and Performance Monitoring are intended for:

- Improvement of efficiency especially in part load operation

- Monitoring efficiency and emissions at minimum, part and base load

Maximizing power plant flexibility

This new white paper explores how CCPPs can respond to current market trends by enhancing their operational flexibility to swiftly respond to market demands. Learn how operational profiles of CCPPs are changing due to the rise of renewable energy sources and strategies for optimizing CCPP flexibility, including improved start-up/shutdown processes and load gradients.
