| contents | Long-duration energy storage (LDES) assets can be fundamental resources for the next-generation power systems. However, LDES technologies are still immature and their future technology costs remain highly uncertain. In this context, we perform in this paper an extensive study to estimate the maximum LDES technology costs (which we define as viability costs) under which LDES systems would be economically viable in each state of the contiguous U.S. according to their characteristics. Our results indicate that only 4 states (out of 48) would be able to remove firm conventional generation supported by LDES systems without increasing their total system costs under the current US-DOE cost target of 1,100 US$/kW for multi-day LDES. In addition, we find that states with the highest LDES viability costs have in general low participation of thermal generation, a high share of wind generation, and higher thermal-related fixed operation and maintenance (FO&M) costs. |
