Progress Energy will be happy to furnish you with a copy of their easement on your property. You will need to go to their website, download the forms, properly complete them, submit them, and wait 90 to 150 days for their reply.
If you need it more quickly, and I sense that you do, you should visit your county registrar of deeds, where the easement should be recorded. You will need the actual terms of the easement to determine what they can cut. Many electric easements give the power company the right to clear on and off the easement based on their sole judgment of what might "interfere" with their operation.
Good Luck
