Regulated Network Reports and Studies
ElectraNet continually aims to plan smarter, manage smarter and work smarter.
The timely and cost-effective establishment of new electricity transmission assets across South Australia is essential. But the current environment of climate change, new emergent technology, and changes to the mix and location of intermittent generation (such as solar and wind) demands that we do so with greater degrees of flexibility.
To manage and plan for these changes in our industry, ElectraNet develops reports and studies in consultation with a number of stakeholders. They include government organisations, the resources sector, and market participants. In particular, we work closely with the Australian Energy Market Operator (AEMO), the national electricity transmission planner, to meet state and national objectives.
The following reports help ensure that the investment solutions we develop for the South Australian electricity transmission network are:
- cost effective
- delivering net benefits to the market
- scalable for changes to demand in a carbon-constrained future.
ElectraNet's Upcoming and Published Reports and Studies
The Australian Energy Regulator (AER) approves ElectraNet’s revenue stream through a revenue determination process, known as the Regulated Revenue Determination Process. The revenue that is determined by the AER is referred to as ‘regulated revenue’, and around 90% of our revenue falls into this category. Regulated revenue covers the expenses that we incur when developing and operating regulated transmission assets. This is also known as ‘prescribed transmission services’.
Each Regulatory Period runs for five years and in January 2017, we will be submitting our Revenue Proposal for the next Regulatory Period, which runs from 1 July 2018 to 30 June 2023. The AER formally commenced this process in late 2015, consulting on aa Framework and Approach paper. This paper broadly determines the nature of the regulatory arrangements that will apply to ElectraNet.
In recent times, there have been important shifts in the drivers of electricity consumption, many of which contribute to a reduction in the energy consumed from the transmission network. This discussion paper looks at the change drivers that impact our network, what the future might look like over the next 10-20 years, and what the implications are for the planning and operation of the transmission network.
It is designed to encourage thinking and discussion and, ultimately, help to align the future of the transmission network with the needs of our customers and consumers. We are now considering the feedback that was received, and when this process is complete, our Network Vision will be published.
ElectraNet’s Transmission Annual Planning Report provides information to market participants and other interested parties on the current capacity and emerging limitations of the South Australian transmission network over a ten-year planning period. An overview of the report is also available.
The report helps potential loads and generators to identify and assess opportunities on the market. It also includes demand forecasts and information on completed, committed and proposed transmission network developments.
We encourage registered participants and interested parties in the National Electricity Market to provide input and feedback on the report’s findings. Advocates of non-network solutions are invited to propose alternative options.
Due to the long lead times in the delivery of transmission infrastructure, forecasting electricity demand and loading conditions is a very important consideration when planning the delivery of reliable transmission services. This report identifies the transmission connection point forecasts that ElectraNet used in our 2016 South Australian Transmission Annual Planning report.
Since 2010/11, energy consumption from the grid in South Australia has been declining. The 2016 report shows a continuing trend towards reduced demand during the day, and that in some cases, transmission network connection points are even experiencing a flow of power injected into the grid.
We encourage registered participants and interested parties in the National Electricity Market to provide feedback on the 2016 South Australian Connection Point Forecasts report.
The Network Capability Incentive Parameter Action Plan (NCIPAP or Action Plan) contains ElectraNet’s program of small scale projects designed to improve the capability of South Australia’s network in the locations that are most important to determining spot prices, and at the times most valued by users. These projects are designed to reduce pressure on electricity prices and network costs, achieved through efficient deferral of network investment, more cost-effective maintenance practices, and smarter ways of managing the network.
Following our extensive consultation with consumer groups and the Australian Energy Market Operator (AEMO), the Australian Energy Regulator (AER) approved the Action Plan in May 2015. This provides the funding for a three year program that started on 1 July 2015. As part of the program, we will invest approximately $10m in six small scale projects to improve the capability of our network.

The participant submissions ElectraNet received as part of this consultation are also available to view:
In 2010, ElectraNet and the Australian Energy Market Operator (AEMO) issued a draft report on the the joint feasibility study done on transmission development options. Feasibility was judged on the potential to economically increase the interconnector transfer capability between South Australia and other National Electricity Market (NEM) load centres.
This final report looks at options for upgrading the high-voltage transmission lines that connect South Australia to the NEM. The upgrade should facilitate increased opportunities for renewable energy development and provide improved network security for South Australia and neighbouring states. The report also responds to a range of issues and questions raised by stakeholders in their submissions.
