Neighbor requests modification to existing easement for electric upgrades

[Nikolas Engel]

Dear all,

A neighboring mixed-use development is requesting to modify an existing easement we have with the electric supplier in our area. The aim is to enable the electric supplier to make modifications to the electrical circuit that runs underground through our property. The neighboring project would be connected to that circuit.  

I have no experience in this matter and ask for help to be not taken advantage off. 

Is this a normal everyday business requests? Is it the industry standard to usually grant those requests for free? Or do they usually come with a financial compensation for the burden involved?

Than you for helping me understand this request. The property is located in Oregon.
