Existing Trustees Bruce Cronin and Ken Collings have chosen not to stand, but current Chair Bill Holland is re-standing.
"I take this opportunity to thank both Bruce and Ken for their outstanding service to TECT", said general manager, Wayne Werder. "Both Bruce and Ken have been long serving Trustees and TECT would not be where it is today without their considered input".
The election is being carried out by both internet and postal voting, with voter packs being sent out on June 27.
This is the sixth election for TECT that has used online voting, but consumers can only vote using one method. If votes are received by both internet and post from the same consumer, both their votes will be invalid. Each consumer is entitled to one vote irrespective of how many power connections they may have. Voting closes at midday on July 22.
