The team spent the first round playing at Peristeri Arena (17 km away from the town of Elefsina), due to necessary renovation to its home court which lasted for about 3 months.

In order to avoid relegation, Panelefsiniakos improved its performance in the following months and got crucial wins at home against PAOK, Panionios and Peristeri.

Greek combo guard Nikos Liakopoulos was the team's season MVP with 15.3 points per game on average and generally had great contribution.

After the end of a successful season, Panelefsiniakos made a lot of important changes to its roster in summer of 2013, including the addition of Olympiacos former captain and Greek NT member Manolis Papamakarios.

Two match days before regular season's end, Panelefsiniakos, led by swingman David Kyles who scored 20 points and grabbed 4 rebounds, crushed Trikala at home and made a decisive step in order to stay at the top division.
