Transmission lines are generally maintained to a higher standard than 
local distribution lines.  There will probably be some noise on the 
lower HF bands, but if the line is well maintained it will not be 
serious.  You will probably notice some difference depending on whether 
you antennas are parallel with the line or not.  I doubt you'll have 
much noise at VHF and above.
I have found the above also.  I have six approximately 115-130KV lines 
running to my north around 2000 feet away.  I have found these not to be too noisy.  
However, the lower voltage lines around here having 15KV that run through the 
neighborhood can produce lots of QRN, especially in the summer when the 
lightning arrestors get fried...lots of S-9 stuff.
