Yes, as I understand it, the long-running political tension between ERCOT and FERC primarily has to do with rate and transmission agreement regulations, not environmental regulation. That said, FERC actually does have a fairly substantial environmental regulation function in that they handle NEPA matters for electrical initiatives triggered by federal policy. So avoiding FERC regulation may avoid having to complete NEPA process (e.g. EIS) in some cases, but it doesn't help with requirements under Clean Air Act/Clean Water Act, which are typically the more onerous for power plants.
