What is a Substation?

Substations are a vital part of the electrical grid. What are they and how do they provide an essential function on the grid?

Interconnecting the Grid

Hoosier Energy has interconnect points with other utilities on the grid. As power is transmitted – either being purchased or sold from one utility to another – equipment known as tie lines are used to provide an economical path for the energy to be supplied to the load.

Mobile Solution

A mobile substation is a large piece of equipment, replicating the job of a stand-alone substation, that can be transported to a designated location, set up and then used for an undetermined amount of time so that service is not interrupted while work is performed on the substation.
