NPRR1020 Allow Some Integrated Energy Storage Designs to Calculate Internal Loads
ReasonMeets Strategic goals; Market efficiences or enhancements; Other: Some recent battery innovations, such as the Tesla Megapack, are an emerging design characterized by a modular (prefabricated) and easy-install form factor, where many of the components of the system typically found outside the battery storage device are instead tightly integrated inside the device. These prefabricated products are not always designed to have internal metering. This NPRR will allow these devices to instead calculate a Load value using internal sensors with the approval from ERCOT. This NPRR also proposes that Resources that receive this treatment must also be compliant with requirements in the SMOG. Tesla recommends NPRR1020 not be implemented until ERCOT determines that any necessary amendments to the SMOG have been implemented.

Summary
This NPRR clarifies that emerging storage technologies can be interconnected and operated as a Resource and avail of Wholesale Storage Load (WSL) rules. Specifically, the NPRR proposes to allow Energy Storage Resources (ESRs) with integrated Loads that cannot be metered as designed, to alternatively calculate these Loads using internal sensors. This process will require an annual attestation from the Resource Entity.
