Plans for the "Reinforcement to North Shropshire Electricity Distribution Network" project were submitted by energy firm SP Manweb last month.
PINS this week announced that it would examine the DCO application under the Planning Act 2008 regime for major infrastructure.
The application proposes installing a new 132kV overhead line travelling 21km between the towns of Oswestry and Wem, involving 12m to 14m high wooden 'trident'-style poles.
It would also involve installing about 1km of 132kV underground cable in and around Oswestry.
According to a statement on the developer's website: "The proposed development will provide much needed additional capacity to the local electricity network in North Shropshire."
It adds: "This line will provide capacity to support development on land allocated for new jobs and homes in Oswestry, Whitchurch and Wem.
"It will attract future business and housing investment across North Shropshire through to and beyond 2036."
In October, PINS announced it would examine a DCO application for a new power line across the Isle of Anglesey in north Wales.
