I know Is geocomm.com permanently unavailable? was asked a few days back and is closed. That is the site I was hoping to buy from initially.
Data providers equivalent to USDA/NRCS/FSA Common Land Unit (CLU)? from 3 years also points to the geocomm site (which is now defunct).
Is it possible to find the 2008 FSA version of the CLU data which was the last version that was publicly available?
NERC & FERC are going to be your best bets in getting correct data.
Not only will you most likely have to pay for the data, but I don't believe you can have access without certifications and clearances (national security threats, etc). Both of the resources above should help you find what you need to do to get the most recent/correct data and the resources to go to in regard to both transmission and pipeline data.
The national map is one source.
BLM Geocommunicator is another
There is a history of the plss system here
Depending on your location you will probably need the blm source data and the alt source data.

FSA's Common Land Unit data contains personally identifiable information, therefore it is not available to the public. For an up-to-date data source, you should check for parcel data from the County Assessor for your area of interest.
