The Power System Review (Review) is prepared by the NT Government's Utilities Commission with the aim to provide the routine release of comprehensive and authoritative data to industry participants, prospective participants, customers, regulators and policymakers.

The North West Integrated System (NWIS) provides the capability to view the Horizon Power Network which services the communities located within the Pilbara region of Western Australia.

The Paleo-Mesoproterozoic Isa Superbasin is located in northwestern Queensland and is part of the geologically complex and resource rich Mount Isa Province. Over the last five years, the Northern Lawn Hill Platform (NLHP) in the northern part of the Isa Superbasin has become a focus for frontier conventional and unconventional hydrocarbon exploration. Thick and extensive organic-rich shale units in the River and Lawn supersequences are of particular interest for unconventional shale gas exploration following a gas discovery in 2014 from the Lawn Shale at Egilabia-2 DW1. Potential shale gas resources in these stratigraphic intervals include 22.1 Tcf of prospective gas and 0.15 Tcf of contingent (2C) gas resources (Armour Energy, 2014 and 2015). Other conventional and unconventional plays may also occur in overlying stratigraphic units within the Isa Superbasin. However despite the increased interest in the region’s petroleum prospectivity, the data coverage across the Isa Superbasin is sparse and aspects of the regional geological framework remain ambiguous. This report presents an update to seismic and well interpretation in the Isa Superbasin originally undertaken in the late 1990’s as part of the North Australian Basins Resource Evaluation (NABRE) Project in the NLHP, the area with the greatest concentration of data and petroleum exploration activity. The NABRE Project focussed on developing an integrated structural and stratigraphic framework for the NLHP in the context of understanding and predicting sediment-hosted mineral deposits. However, the project did not produce depth-converted structure or isopach maps, which are required for assessing and mapping conventional and unconventional petroleum plays. Assessments of the area’s resource potential would also benefit by incorporating some key recently acquired data sets and published research with the original NABRE work. The original NABRE work has therefore been updated to include interpretations from new seismic and well data, and to generate depth-converted structure and isopach maps for eight key stratigraphic horizons of interest for petroleum exploration in the NLHP. Major sub-surface structures are also formally defined and named based on the depth-structure maps. The review of the Isa Superbasin geological framework presented here underpins work on two major federal government initiatives, the Exploring For The Future Program and Geological and Bioregional Assessment Program. Recommendations are included in this report on further value adding work that could supplement these programs to better inform prospectivity assessment.

This dataset was produced by a NESP project, and contains 5 m resolution bathymetry tiles with national Australian coverage of both coastal and outer marine regions. The data product contains 'bathymetry' and 'shelf bathymetry', with the shelf bathymetry constrained to the 0-200m depth region. Files are in RGB geotiff and ASC grid format, zipped as *.gz. Tiles are 0.5x0.5 degrees.

The Network Capacity Mapping Tool (NCMT) provides the capability to view Western Power’s current and proposed electrical network in the southern region of Western Australia.
