Introduction

Electric Storage Resource (ESR) is a resource capable of receiving Energy from the Transmission System and storing it for later injection of Energy back into the Transmission System. This definition includes all technologies and/or storage mediums, including but not limited to, batteries, flywheels, compressed air, and pumped-hydro. The location of an ESR may be at any point of grid interconnection, on either the Transmission System or a local distribution system, but must not be outside the Transmission Provider Region. An ESR must: (1) be capable of injecting and withdrawing a minimum of 0.1MW; (2) be capable of complying with the Transmission Provider’s Setpoint Instructions; (3) have the appropriate metering equipment installed; and (4) be physically located within the MISO Balancing Authority Area. The State of Charge shall be managed by the Market Participant operating the ESR. An ESR shall also be deemed a Generator based on and in contexts relevant to, its capability to inject Energy back into the Transmission System.
