When completing the Resource Asset Registration Form (RARF), what is needed for “Provide kV Base” for transformer data?

0

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.
