Capturing emergency access gates and tracks for Endeavour Energys network.

Business Challenge
Endeavour Energy (formerly Integral Energy) distributes and retails electricity and services to 2.1 million people. In addition to electricity retailing, Endeavour Energy also owns a $2 billion electricity distribution network spanning 24,500 square kilometres in Greater Western Sydney, the Illawarra, and the Southern Highlands.

As part of its emergency response preparations Endeavour Energy determined that comprehensive corridor access information was required to enhance response efforts to incidents that may occur on its network. Endeavour Energy decided that it needed to locate and assess the position of gates and access tracks and make this information available to its service crews.

Services Overview
With extensive experience in electrical asset capture projects, Geomatic Technologies (GT) was approached by Endeavour Energy to map all access tracks adjacent to the transmission corridors.

The Endeavour Energy mapping requirements included detailed definitions of access track tee-offs and practical terminations. Further details such as track restrictions, cattle grids, gate types, gate width measurements, as well as track width and track condition rules needed to be captured. The mapping requirements were imparted to the GT project team over a 2-day training and observation period.

A single 4WD mapping vehicle was configured with GT’s Asset Inspection Mapping System (GT AIMS). Endeavour Energy supplied GT with an extract from its GIS that contained the NSW public road network and high-resolution aerial imagery of power infrastructure (i.e. conductors and substations). Access tracks were ‘coordinated’ using differential GPS as the mapping vehicle transited their length. Each track was represented by a series of nodes supplied at a 5m interval with relevant features snapped to the track alignment.

Track topology and relationships to the public road network were maintained (essentially the data supplied by GT could be used in a routable navigation dataset). Both sides of the 132kv, 66kv and 33kv transmission corridors were mapped and digital photos were taken of track features that did not conform to the standard Endeavour Energy mapping specification.

The GT team visited and mapped all high voltage poles and towers. The most logical entrance and exit points to the transmission corridor from the public road network were also surveyed along with vegetation growth, access gates, security features and road surface condition. The deliverables to the client included the production of 1:25,000 scale hard copy map books showing electrical assets, access tracks and gates.

Outcomes
Through its asset capture services GT provided the following outcomes to Endeavour Energy:

– The comprehensive corridor access information supports enhanced incident response on the Endeavour Energy network.

– The client received a spatial database of access track assets to +/-2m accuracy and suitable for the navigation of emergency vehicles.

– The well-structured spatial dataset that was delivered could be readily consumed by the client’s GIS system.
