Substation perimeter fencing one of the “greatest failure risks” for zone substation equipment
In Essential Energy’s Regulatory Proposal 2009-2014, under the heading ‘Asset Renewal Programs and Initiatives’, substation perimeter fencing is identified by Essential Energy as one of eight components representing “greatest failure risks” for its zone substation equipment (p.113). One of the primary risks arising from such failure is unauthorised access into the substation. The resulting risks and adverse outcomes of which include: the theft of valuable assets (requiring replacement), the damage to assets (requiring repair or replacement); the loss of power supply (resulting in cost and inconvenience to customers); and electrocution resulting in the serious injury or death of person(s).
