Frontiers | Economic Analysis of Transactions in the Energy Storage
The charging and discharging efficiency of ES varies with the charging and discharging times and operating time. The investment and construction costs of an ES power
Energy storage has a slightly more complex relationship with interconnection processes, not only because it offers to supply electricity that could affect grid stability, but also because storage devices, particularly stand-alone storage, act as demand for grid electricity when charging.
Energy storage can also support resource adequacy by counting toward a system's total installed capacity. Through capacity markets or other resource adequacy constructs, storage providers are compensated for their potential to provide energy in the future, particularly when the expectation is that demand will be high or supply low.
Challenges will continue to emerge as more storage resources come online, and market design and regulations could play an important role in ensuring that energy storage resources are appropriately incorporated without interfering with critical market functions. 5. Evidence on Storage Deployment in the US
Some storage owner/operators with extensive experience may prefer to manage their own state of charge, even if they face penalties for not meeting their product obligations. Other, newer entrants may prefer state of charge to be managed by the system operator to reduce penalty risk.
