In the course of working towards our mission, talented SEN members have created a number of reports, submissions, presentations and media statements. You can find a selection of these publications in this section, by clicking on the links below. These publications are well worth a read to find out more about SEN and our research into renewable energy technology, implementation and policy.


SEN Submission to the Wholesale Electricity Market Rule Change Committee.

Amending the Minimum STEM Price definition and determination (Rule Change Proposal). It is the opinion of SEN that the Rule Change Proposal fails to address the central issues associated with the cause(s) of outcomes of negative clearing prices and furthermore it does not make a case as to how the proposed changes will address the unintended consequences raised.

SEN Submission to the WA EPA regarding Woodside's Browse and North-west Shelf Proposals

Woodside’s proposed Browse Basin development will emit 4 gigatonnes of GHG pollution over its 30-50 year lifetime.

This includes 4.8 megatonnes of ‘reservoir CO2’ each year, which will be vented to the atmosphere.

It will increase by 19% the emissions needing to be reduced elsewhere by 2030 under Australia’s Paris target.

There are numerous flaws and misrepresentations in the Woodside proposals:

  • They do not clearly report estimated methane emissions
  • They under-estimate methane’s Global Warming Potential (GWP) by calculating the effect over 100 years instead of 20 years (which is 84 times more damaging than CO2);
  • They attempt to conceal the magnitude of the reservoir CO2 emissions;
  • They use an unrealistic and discredited projection of global gas demand, which is at odds with other projections

Furthermore, Woodside is making no realistic attempt to avoid, minimise or offset these emissions.

Woodside repeatedly claims, incorrectly, that gas is 50% less polluting than coal. SEN’s analysis shows that gas is at best 25% less polluting than coal.

This massive gas development cannot proceed if the world is to keep global warming within 2.0ºC.

SEN Sensitivity of Electricity Prices to a Carbon Price on the South West Interconnected System submission to Energy Policy WA. 

Energy Policy WA has been developing a Whole of System Plan (WoSP), but a carbon price has not been considered in the modelling. This report argues that there are national and state requirements to manage climate risk, and provides a well-researched sensitivity analysis which shows that various levels of carbon price can add 20-50% to the wholesale cost of electricity. Our conclusion is that modelling and decision making which does not include consideration of a carbon price is flawed, given the size of the effect indicated by this sensitivity analysis. The report itself outlines some of the implications.


SEN Submission to DWER to inform the formulation of Climate Change policy in Western Australia

SEN has responded to the Department of Water and Environmental Regulation's Climate Change issues paper.

Among other things, the submission:

  • quantifies the scale and scope of the emissions' reductions required to meet state targets.
  • summarises Negative Emissions Technologies and fuel switching approaches which can be applied or developed.

SEN has outlined targets that need to be met to meet the State's responsibility to meet WA's share of the national target of 28% emissions reduction over 2005 levels by 2030. To achieve this, the State needs to:

  • Find 37 Mtpa of total abatement, to move from 88 Mtpa (in 2017) to 51 Mtpa in 2030.
  • Reduce total emissions by at least 3.7 Mtpa CO2e per year between 2020 and 2030, equating to a total reduction of 37 Mtpa.
  • Reduce energy sector emissions to 45 Mtpa by 2030, at a rate of at least 4.5 Mtpa CO2e per year. This figure is higher because some emissions are being offset by land use activities.

SEN Submission to EPA on Greenhouse Gas Emissions Guidelines

This submission responds to the Environmental Protection Authority consultation about Guidelines to consider greenhouse gas emissions in its future assessments of developments in Western Australia. SEN has reviewed the Guidelines in terms of the latest scientific understanding, agrees with their content as an appropriate minimum first step, and suggests some extensions to the guidelines.


SEN Submission to Microgrid Inquiry, April, 2018 to the Inquiry into Microgrids and Associated Technologies in WA, conducted by the Economics and Industry Standing Committee of the Legislative Assembly.

In this submission, SEN has provided an independent assessment of the emergence and impact of Microgrids and associated technologies in Western Australia. This assessment unequivocally finds that Microgrids, in all their forms, will contribute to a necessary modernisation of Western Australia’s electricity system, ultimately reduce costs to consumers, and contribute to Australia’s carbon pollution reduction goals.   SEN believes that the most important next step is for Government to set a vision and put a policy framework in place, to meet public expectations, and provide direction for Government agencies.


SEN Submission to Fracking Inquiry March, 2018 to the Independent Scientific Panel Inquiry into Hydraulic Fracture Stimulation in Western Australia 2017

This submission analyses the risks involved in Fracking, and establishes that unconventional gas supplies are not needed in WA, because the state has sufficient proven reserves of conventional gas to meet its needs into the foreseeable future. The conclusion drawn is that the most certain way of minimising the risks posed by fracking is not to do it at all.

Our latest submission on the WA Electricity Market Reform


A report “100% Renewable Energy on the SWIS” (Part1Part2Part3) with accompanying PowerPoint presentation [4.6 MB], and YouTube video presentation to The Water Corporation of WA’s “Environmental Master Class” in November.  This study determines potential scenarios for WA's South West Interconnected System (SWIS) electricity grid demand to be fully met by a combination of renewable energy generation, efficiency, storage and demand-side management by 2029.  It was commissioned to prior to the 2013 State election by the WA Greens.
