Does anyone have a good source for these? I have some old (1993) data from the US National Renewable Energy Laboratory (NREL) and Cubewerx' WMS (Cubewerx are a spatial data provider); neither of which are very accurate. Pipeline shape files other than the 10 year old NPMS data would also be helpful. Thanks

to clarify the 1993 NREL data is here: mapcruzin.com/… Looking for something more accurate and recent. – sirgeo Feb 16 '11 at 17:03
I bet users of the GTC-EPRI siting model know where to get this data. gatrans.com/PlanningConstruction/EPRI-GTCSitingModel/index.htm You might try contacting them. – Kirk Kuykendall Feb 16 '11 at 18:51

NERC & FERC are going to be your best bets in getting correct data.

http://www.nerc.com

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.

This is not generally free data. Two providers I've used are Platts and Ventyx. Costs are roughly the same (not cheap!) and I've found the Ventyx stuff to be more detailed though Platts has been better on occasion.

right on Swingley, we are probably going to be having to purchase the data. Thanks for the Platts and Ventyx links, we were thinking of purchasing from RexTag rextagstrategies.com but those might be better. – sirgeo Feb 16 '11 at 17:35
