When completing the Resource Asset Registration Form (RARF), what is needed for “Provide kV Base” for transformer data?
The KV Base is needed to identify the base voltage used in the per unit calculations associated with the transformer data. Electrical systems are often modeled on a per unit basis. In order to make per unit calculations useful to ERCOT, the base for MVA and KV must be disclosed. For the step-up transformer, ERCOT has requested that the MVA base is 100MVA. Since the MVA base is given, the resource needs to provide the kV Base in the RARF.
