Abstract:
A major challenge of the current environmental crisis we are facing is the decarbonization of our energy system. One way to support this is the use of battery storage systems. Until now, an economic application of these was considered difficult. However, due to the adjustment of regulatory framework, the use of these is becoming increasingly economical in Germany. In use case 1, a 10 MW/ 11MWh battery storage system installed in distribution grid A is investigated and an amortization of 8 years through avoided grid usage fees resulting from §18 StromNEV and the selling of residual flexibility is achieved. Special forms of grid usage such as atypical and energy-intensive grid usage are derived from §19 StromNEV. The fulfillment of respective requirements can be supported by reducing peak loads through battery storage systems. In use case 2, a 1 MW/ 1.5 MWh battery storage system is designed to meet the atypical grid usage requirements for Company B, achieving a payback period of 12 years. In use case 3, a 1 MW/ 1.8 MWh battery storage system is used to meet the requirements for energy-intensive grid usage for Company C. This shows a payback in the second year. In both cases, additional revenues can also be generated by selling the residual flexibility, but were not considered in more detail in this paper. In summary, it can be said that the regulatory framework creates already economic incentives for investments in stationary large-scale battery storage systems. Since the future of this particular regulatory framework is still uncertain, battery storage systems can indeed become essential pieces of the announced energy transition, further incentives for the construction of battery storage systems must be provided.
