Career Job

I am doing my Masters in Power systems(Electrical). Iam now working in
an office as a data entry operator.My job is to keep a record of all
the accounts for gas stations.My boss owns nearly 40 gas stations.

My boss has given me an offer to do Co-op ( I dont know whether it
would be an internship or co-op) which means that i have to do in the
related area of power systems only inorder to qualify for that.

Can some one suggest me what could be a related job concerned to this
Gas stations and related to Power systems as well.

Thanks,
Friend in need
