Tracks: Track 2: Repositioning Conventional Power Generation

Due to the global and national efforts to reduce the CO2 exhaust by substituting more and more fossil power generation with renewable generation all future energy grid systems will have to solve the challenge of managing decentralized volatile generation and consumption. Already today some grid operators in Germany have to face the situations of imbalanced balance groups while flexible gas power plants are down due to uneconomic generation. However, increasing needs for these services lead to the question how existing assets can be enabled to deliver such and even more how they actually can be leveraged into new compensation models by combining them with new battery storage systems and intelligent software solutions. Battery storage can be a solution that allows reducing opportunity costs, and structuring the operation and maintenance of a stranded gas turbine more efficient on the one hand and making other markets for stranded assets accessible again by making use of its high flexibility and fast response times on the other. Its field proven performance reliability provides the required system security to achieve a secure hybrid energy asset – called a “Kombikraftwerk” or hybrid power plant. Based on a pilot project in Germany where a battery energy storage system enables a gas turbine to be economically operated in the primary and secondary reserve market, this paper will discuss the fundamental challenges which this hybrid project faces in order to achieve an economical operation. At a second stage the experiences made with this project can serve to discuss technical performance and resilience as well as the financial perspective. This feasibility investigation will elucidate the potential for a repeatability pattern for up to 250 other stranded assets in the German market region that could be updated into profitable market participants providing grid stability and energy.
