National Grid applied to install the overhead line which would carry electricity from the proposed new nuclear power station, Hinkley C.
The Planning Inspectorate has announced it will hold a six-month inquiry, during which local people can comment.
It will then make a recommendation to the Secretary of State.
Sir Michael Pitt, chief executive for the Planning Inspectorate, said the application "met the required tests" and the decision was made after "careful consideration".
"The applicant must now decide when to publicise the fact that its application has been accepted to proceed to examination and announce when members of the public will be able to register with the Planning Inspectorate as an interested party in the application," he added.
The National Grid plans were submitted last month. A company spokesman previously said it had taken "five years of consultation".
It will see 30-miles of overhead wires carried on pylons and a five-mile section under the Mendips, connecting the station, near Bridgwater, Somerset, to the National Grid's 400,000 volt substation at Avonmouth.
It would also see the removal of 246 pylons and 42 miles of cabling between Bridgwater and Avonmouth, and Nailsea.
Those against the pylons argue the entire route should be underground or sub-sea - but National Grid had previously said this option would be too expensive.
Now the plans have been accepted for examination, the documents will become public. A final decision will not be made until late 2015.

Officer William Porter, charged with manslaughter, has said he did not call for a medic for Freddie Gray because he had no reason to do so.
A prosecutor said Mr Porter could have easily called for a medic or used a seatbelt in the back of a police van.
Gray died a week after sustaining a spinal cord injury in the van.
His death sparked protests over police brutality, with the city of Baltimore erupting in rioting, looting and arson on the day of his funeral.
Prosecutor Janice Bledsoe said during closing arguments that Mr Porter "just didn't care enough" to secure Gray with a seatbelt or call for medical attention.
Mr Porter said he checked on Gray during the stops, and he had no signs of injury.
He is charged with manslaughter, assault, misconduct in office and reckless endangerment and could receive up to 25 years in prison.
Other officers' saying they do not use seat belts on prisoners is not an excuse, she said.
Mr Porter said Gray asked for help getting off of the floor of the van and denied claims that Gray told him he could not breathe.
However Mr Porter did say he hear Gray say something about needing an inhaler upon his arrest.
He said in 200 arrests involving the van, he has never belted a prisoner because the wagon is "pretty tight".
"External facts" show Mr Porter is telling the truth, his lawyer Joseph Murtha said, according to the Baltimore Sun.
Mr Murtha said Gray's death was a "horrible tragedy" but that there is no evidence Mr Porter is responsible for it.
Concerned about possible unrest after the verdict, Baltimore is opening an emergency operations centre as the trial wraps up.
Mayor Stephanie Rawlings-Blake has said she is sure city officials are prepared for any protests that may arise.
Five other Baltimore police officers will go on trial in Gray's death. All have pleaded not guilty. They will be tried separately and prosecutors hope to use Mr Porter as a witness in the other trials.
Plans for more than 140 pylons connecting Hinkley Point to Avonmouth have been accepted for examination by the government.
