I can only refer you what the Supreme Court ruled in Kyllo v. United States

"Cory Borgeson, president of the Golden Valley Electric Co. in Fairbanks, Alaska, told NPR he is stunned at how easily the government can obtain personal information with subpoenas. For instance, agents at the Drug Enforcement Administration wondered if some of Golden Valley's customers might be making or growing drugs in their homes. Drug dealers sometimes use more electricity than normal, and their power consumption records can potentially be a clue. So the DEA served a subpoena on the utility, ordering it to turn over detailed digital records on its customers' electricity use, bank and credit card accounts, and other information. Borgeson says the standard for getting a subpoena is so low that it's essentially "one agent turning to [his or her colleague] and saying, 'Would you please sign this administrative subpoena for me so I can get information?' "
Golden Valley tried unsuccessfully to block the subpoena in court by arguing that the government needed a search warrant."

said by Snakeoil:Though supposedly before they check utility records they have night flights that do a thermal image scan of the area they are interested in.
This is an illegal search and won't hold up in a court of law. But they can get the electric records easily so it makes no sense to think that they would compromise their investigation with a warrantless search when they already have access to the utility records directly and legally.
