Generator guidelines
If you plan to connect a generator to SRP's electric system, or already have done so, please review the
Interconnection Guidelines for Distributed Generators.
Questions about interconnected generators
When do I need to follow the interconnection guidelines? If your generator
(including solar power) and SRP's electric distribution system can be connected together such that both
sources can supply electricity to the same electrical load at the same time, even if just for a split second,
then you have an interconnected system and the above guidelines apply.
If my generator is not connected to SRP's system, is there anything I still need to know?
Yes. In that case, please review:
An example of a generator not connected to SRP's system is one that can only be connected to a customer's
electric system by operating a transfer switch. The switch first disconnects the customer system from the
SRP system, then connects the customer system to a generator and is commonly called an "open transition" transfer switch.
