funny story.. the other day i was at the bar getting a drink and this guy comes and sits near me and i noticed he was carrying his hard hat which said "Choptank Electric Co-op" on it so i asked him if he worked for CEC and he said yes. I asked him some questions and heres some things he told me.

Distribution: 7.2/12.5kv wye.
Subtransmission 69kv/34.5kv (34.5kv more rare).

and i asked him if they get their power from Delmarva Power and he said no... he said they don't get along with that company no more and said they now get their power form old dominion. i thought that was odd since i saw one of their subs fed by a DP&L 69kv line.... interesting stuff!
