Key Points

• The Australian National Electricity Market (NEM), burdened by the effect of the Renewable Energy Target (RET) schemes, is no longer capable of delivering a reliable, affordable and sustainable electricity supply. The NEM, or the RET schemes, or both, will need to be changed to avoid serious failure of the power system in the future.
• This paper sets out in plain English a statement of the problem, a diagnosis of the underlying causes at the root of the problem, remedies that have been proposed to solve it, and a vision for reform that would require minimal design changes to create the next generation electricity market.
• Six symptoms of the problem evident in the NEM have been identified, which adversely affect power companies, as well as business and household consumers. The root causes are found in conflicts between the design principles on which the NEM is based and those of the RET schemes.
• Seven possible responses have been identified, which are considered remedies rather than options, as some of them are potentially complementary. Some remedies would involve retreating from the competitive electricity market reforms of the 1990s, while others would take the reforms to a more mature stage.
• The paper makes recommendations that could redress the root causes of the problem, with a minimum of disruption to consumers, the electricity system and the market, and reduce rather than escalate government intervention.

Key Points

• The increasing penetration of variable renewable energy (VRE) in the National Energy Market (NEM) is causing the closure of coal- and gas-fired power stations, threatening power system security and creating unmanageable risks for investors. This is giving rise to social effects for which the community is not prepared and is occurring during a period of heightened community dissatisfaction with traditional political processes.
• The contemporary investment risk profile of each of the three main components of the power system: generation, networks and downstream supply, could not be more different.
• There is plenty of money available for investment but electricity generation has become a ‘no-go zone’ unless it is supported by government subsidies or by power purchase agreements (PPAs).
• Investment in electricity networks is almost the opposite - institutional investors are queuing to invest because independent economic regulation provides them with predictable long-term revenues.
• The NEM is in need of fundamental redesign.
• Sound economic and scientific information on energy, as well as new processes of end-user and community consultation, will be required to gain community support for the necessary reforms but the focus of reforms should be the formulation of a truly national energy vision.

Key Points

• Power systems have fundamental needs: load following, flexibility and dynamic response.
• Increasing intermittent renewable generation in a power system has a “pressure cooker” effect and can involve an unaffordably high level of integration costs.
• Every power system is different but, in most systems, the practical upper limit for renewables is around 40% of total electricity generated. This may be exceeded but it is likely to require a greater level of interconnection with adjoining power systems, more energy storage, increased recourse to demand-side management and regulatory changes.
• The scale-up of intermittent renewables not only diminishes the robustness of a particular power system but can also magnify the short and long-term risk of investing in non-renewable generation assets and the power grid itself.

Key Points:

• After a year-long inquiry, the Australian Competition and Consumer Commission concluded that east coast gas markets are competitive, but that pipeline operators are exercising market power. 
• During the period of the inquiry, east coast gas prices have been affected (and continue to be affected) by growth in demand for export LNG, volatility in oil prices (against which export LNG prices are pegged), and static domestic demand for gas, leading to shortages and higher prices for domestic users.
• The ACCC conclusion is based on anecdotal evidence, and the inquiry did not conduct a forensic investigation into prices, costs and profits, leading some industry participants to contest the findings that pipeline charges (rather than other market forces) have adversely affected household gas prices. 
• The ACCC considers that current competition law does not address the inefficiencies they perceive, since they have concluded that east coast gas markets are competitive.  The ACCC has proposed changes to the gas pipeline access regime because the ACCC considers that the regime does not adequately control what it considers to be excessive pipeline charges. 
• In questioning the ACCC’s conclusions and recommendations, this paper advocates three points.

Key Points

• National economies and infrastructures are heavily dependent on the energy sector, which itself is increasingly dependent on Information Technology (IT) systems.
• Ensuring security of supply is an urgent priority in the face of the increasing need for diversity of renewable and clean energy supply, evolving standards, and the escalating sophistication of the cyber security challenges.
• The solution requires an effective energy and climate policy framework, strong industry leadership, and a pro-active bias for collaboration in the energy sector ecosystem to address security of supply and the cyber security challenges.
• A disciplined "Systems Engineering" approach, that considers all facets of the complex energy system, including policy, regulation, technology, supply chain, standards, processes, people, detection, protection and defence, remediation, and compliance, can provide the framework to more effectively manage the cyber security challenges and provide a more holistic, coordinated and increased cyber-readiness capability for the Australian energy sector.

Key points:

• The Goverment of New South Wales seems to have only recently realised the full significance of community engagement in relation to energy resource development.
• The overhaul of the New South Wales resource exploration regime is a positive step in providing more control to Government over the development of the State's onshore natural gas resources.
• An energy vision would provide a greater sense of legitimacy for resource development and contribute to policy certainty that highly capital-intensive investments in the energy sector require.
• An energy vision should enable consideration and integration of multiple perspectives and objectives and ensure social values and environmental objectives are placed at the core of future energy policies.
