from energy storage. The lessons learned in Phase 1 owe a lot to the complexities that surround modeling energy storage technologies in the MISO environment. Conclusions and Recommendations Phase 1 of the Energy Storage Study has allowed MISO to become familiar with challenges inherent in modeling energy storage technology in a complex nodal market with an ASM. The study group has gained a good understanding about storage modeling using EGEAS, which is the primary MISO tool for transmission resource planning. The study results demonstrate that there is economic potential for energy storage in the MISO footprint. Benefits were observed in cases using both EGEAS and PLEXOS. These benefits will be explored in greater depth during Phase 2. The Phase 1 results show that EGEAS is not the right tool to properly understand energy storage potential. The critical role for EGEAS is in identifying cases where storage is beneficial so that these cases can be analyzed further by PLEXOS in the Phase 2 study. The PLEXOS experience during Phase 1 allowed for fine-tuning the model parameters and important lessons were learned regarding storage model setup. The cases to be modeled in Phase 2 have been selected. Phase 2 of the Energy Storage Study will provide richer analysis from which to make conclusions and recommendations. Considerable groundwork has been accomplished in Phase 1. This report will provide extremely useful reference material for industry transmission planners. Report Organization This report covers Phase 1 of the MISO Energy Storage Study. The first chapter provides an introduction and background to the Energy Storage Study. Chapter 2 introduces the MISO transmission-planning environment. The MTEP process is described as well as the recent Regional Generation Outlet Study (RGOS) and subsequent adoption into MTEP of portfolio/scenario analysis to identify multi-value projects (MVPs). The future scenarios and sensitivities used by MTEP are reviewed because they form the basis for the modeling scenarios in the energy storage study. Chapter 3 reviews the energy storage technology landscape and then provides more detailed technology descriptions for the three key storage technologies - compressed air energy storage (CAES), pumped hydro storage (PHS) and battery that MISO is evaluating in the Energy Storage Study. Chapter 4 describes the current MISO ASM for storage including unresolved differences between the FERC and the MISO concerning stored energy resource treatment. Chapter 5 reviews the modeling tools and methodology that MISO used for the Energy Storage Study. The use cases and parameters for the EGEAS and PLEXOS models are provided, together with the assumptions for model scenarios.
Chapters 6 and 7 contain the results and analysis from modeling. Chapter 6 covers the EGEAS model and Chapter 7, PLEXOS. In this first Phase study report, the PLEXOS results are only preliminary. Chapter 8 presents conclusions from the study results, a preview of Phase 2 analysis to-date and potential next steps for MISO including recommendations for future adjustments to the MTEP process.
