To provide the solar power industry with a data resource to allow them to assess the economic potential of a site for a solar power plant. Specifically under the Solar Flagship program.

High voltage transmission towers are key linear assets that supply electricity to communities and key industries and are constantly exposed to wind effects where they traverse steep topoloty or open terrain. Lattice type high voltage transmission towers are highly optimised structures to minimise cost and reserve strength at design wind speeds (Albermani and Kitipornchai, 2003). The structures are tested under static loading conditions for specified load cases at the design stage. However, the interconnected nature of the lattice towers and conductors present a complex response under dynamic wind loading in service (Fujimura, et.al., 2007). The transmission tower's survival under severe wind and additional load transfer due to collapse of its neighbours is difficult to assess through modelling. Furthermore, the lack of data in the industry doesn't allow for a probabilistic analysis based on history (Abdallah, et.al., 2008). Hence, there is a need for developing an alternative methodology for analysing transmission tower collapse and survival of transmission lines subjected to cyclonic winds utilising design information, limited filed data and industry expertise. Methods: This paper presents a noval methodology developed for the Critical Infrastructure Protection Modelling and Analysis (CIPMA) capability for assessing local wind speeds and the likelihood of tower failure for a range of transmission tower and conductor types. CIPMA is a program managed by the Federal Attorney-General's Department and Geoscience Australia is leading the technical development. The methodology explicitly addresses the highly direction-sensitive nature of tower/conductor vulnerability which varies greatly. It has involved the development of a vulnnerability methodology and heuristically derived vulnerability models that are consistent with Australian industry experience and full-scale static tower testing results. This has been achieved through consultation with industry...

A newsletter to Project Stakeholders to inform of progress and future events

The article provides an annula update on Australia's energy scenarion, focussing on offshore oil and gas exploration and production and advertsing the current open acreage release round.

The purpose of The Energy Infrastructure Australia Map, is to provide an overview of the location of Energy Infrastructure facilities in Australia.

The Australian Solar Energy Information System V3.0 has been developed as a collaborative project between Geoscience Australia and the Bureau of Meteorology. The product provides pre-competitive spatial information for investigations into suitable locations for solar energy infrastructure. The outcome of this project will be the production of new and improved solar resource data, to be used by solar researchers and the Australian solar power industry. it is aimed to facilitate broad analysis of both physical and socio-economic data parameters which will assist the solar industry to identify regions best suited for development of solar energy generation. It also has increased the quality and availability of national coverage solar exposure data, through the improved calibration and validation of satellite based solar exposure gridded data. The project is funded by the Australian Renewable Energy Agency. The ASEIS V3.0 has a solar database of resource mapping data which records and/or map the following Solar Exposure over a large temporal range, energy networks, infrastructure, water sources and other relevant data. ASEIS V3.0 has additional solar exposure data provided by the Bureau of Meteorology. - Australian Daily Gridded Solar Exposure Data now ranges from 1990 to 2013 - Australian Monthly Solar Exposure Gridded Data now ranges from 1990 to 2013 - Australian Hourly Solar Exposure Gridded Data now ranges from 1990 to 2012 ASEIS V3.0 also has a new electricity transmission reference dataset which allows for information to be assessed on any chosen region against the distance to the closest transmission powerline.
