Polanza thermal power plant energy storage

How a thermal energy storage system is integrated into a power plant?

The thermal energy storage system is integrated into the power plant in order to reduce the minimal load operation of the auxiliary boilers. The fully charged storage can assume standby operation, which was to-date the operation in the minimal load of an auxiliary boiler.

What is thermal storage power plant (TSPP)?

Thermal Storage Power Plants (TSPP) that integrate solar- and bioenergy are proposed for that purpose. Finally, in the third phase, renewable power supply can be extended to other sectors via power-to-X technologies, reducing fossil fuel consumption for transport, heat and industrial purposes.

How efficient is a thermal power plant?

Up to 8.68% exergy loss is saved during the charging process of the new system. The round-trip efficiency of the proposed system can reach as high as 85.17%. Thermal power plants are required to enhance operational flexibility to ensure the power grid stability with the increasing share of intermittent renewable power.

How can thermal energy storage improve the economic feasibility of CSP plants?

The integration of a thermal energy storage system which makes the electricity production more flexible improves the economic feasibility of CSP plants. More than half of the CSP facilities (51%) currently operating in the world include TES systems [ 25 ], storing the energy surplus to be used during high demand periods.

How can thermal storage power plants reduce the residual load gap?

The following key measures were introduced for its realization: 1. Introducing Thermal Storage Power Plants (TSPP) with about one third annual photovoltaic electricity share will reduce the need of renewable fuels for firm and flexible power generation to close the residual load gap.

Do thermal power plants need thermal energy storage?

Thermal power plants are required to enhance operational flexibility to ensure the power grid stability with the increasing share of intermittent renewable power. Integrating thermal energy storage is a potential solution.
