Additional Information As previously reported, there have been a number of issues identified during past audits of Council’s Safety, Reliability, Maintenance & Technical Management Plan. The manner in which these issues have been and/or are to be addressed is subject to Council Electricity Supply Budget determination on a yearly basis. I am able to advise that Council has proposed to Energy Division that an allocation of $450,000 be included in the 2013 / 2014 Electricity Supply Budget for the replacement of 16 x 6.6/11kv transformers that have been identified as containing PCB’s. These were delayed in production and have now arrived. The installations were due to be completed in the 2014 / 15 year, but to-date 11 have been replaced and the balance will be completed in the 2016 / 2017 year. Additionally Council received an allocation of $130,000 in the 2014 / 2015 Electricity Supply Budget for the removal (5) and replacement (9) of Stobie poles that are located on dugout (underground homes) roofs. The first stage of placement of new Stobie poles to re-route the conductor around the dugouts has commenced.
