  • A South Australia's Electricity and Gas Industries
    A South Australia's Electricity and Gas Industries Both the electricity and gas industries in South Australia have undergone a range of significant reforms over the last fifteen years, commencing with the vertical disaggregation of the electricity and gas supply chains in the mid-1990s and culminating with the introduction of FRC for customers of all sizes during 2003-04. In the wake of FRC, gas and electricity retailing in South Australia has moved from a single host retailer model to a multiple retailer model. The remainder of this appendix provides both an historic perspective on the reforms that were undertaken in advance of the introduction of FRC and an overview of the current structure of energy retailing. A.1. Progression to FRC A.1.1. Electricity industry progression to FRC Between 1946 and 1995, the Electricity Trust of South Australia (ETSA) was responsible for undertaking all aspects of the electricity supply chain in South Australia including the generation, transmission, distribution and retail sale of electricity. On 1 July 1995, the Electricity Trust of South Australia was corporatised and became ETSA Corporation under the Public Corporations Act 1993. In January 1997 the South Australian Government undertook the first steps towards vertical disaggregation, by transferring ETSA’s generation assets to SA Generation Corporation. The second step toward vertical disaggregation occurred in October 1998 when the South Australian Government announced that, in order to meet its commitments under the Competition Principles Agreement and in preparation for entry into the NEM, ETSA Corporation and SA Generation Corporation would need to be further disaggregated.

  • Application for Revocation of Coverage of the Moomba to Adelaide Gas
    Review of the Moomba to Adelaide Pipeline System Application for Revocation of Coverage by Epic Energy P/L Response to the National Competition Council Issues Paper April 2005 by The Electricity Consumers Coalition of South Australia May 2005 Assistance in preparing this submission by the Electricity Consumers Coalition of South Australia was provided by Headberry Partners Pty Ltd and Bob Lim & Co Pty Ltd. The content and conclusions reached are entirely the work of the Electricity Consumers Coalition of South Australia and its consultants. ECCSA comments on the Revocation of Coverage of MAPS 2 1. Introduction The Electricity Consumers Coalition of South Australia (ECCSA) represents several major electricity, gas and gas pipeline users in South Australia. ECCSA was formed in 2001 to promote competitively sustainable prices for energy and energy infrastructure and improved reliability and service quality. ECCSA members comprise representatives from the following companies: OneSteel, Holden, Adelaide Brighton Cement, Zinifex, Mitsubishi Motors, Kimberly Clark, Seeley International; and Amcor. ECCSA welcomes the opportunity to provide its views to the National Competition Council concerning the application for revocation of coverage for the Moomba Adelaide Pipeline System (MAPS). ECCSA members are major manufacturing entities in the State undertaken significant new investments in the State, and are major employers, especially in a number of regional centres. The cost of energy (both electricity and gas) is a significant element of the cost of production to all ECCSA members, as well as to many other businesses throughout South Australia. Additionally as over 50% of South Australia’s electricity supplies are based on using gas as a fuel, the cost of electricity in the State is also heavily influenced by the cost of gas delivered to the various electricity power stations – increased fuel costs will lead to higher electricity prices, and currently South Australia’s electricity prices (both current and forecast) are the highest in the National Electricity Market.

It describes the operations of the Technical Regulator for the financial year 2015/16 as required by sections 14 and 25 of the Acts respectively. These sections require the Minister to cause a copy of the report to be laid before both houses of Parliament within 12 sitting days after the receipt of the report. The Energy Products (Safety and Efficiency) Act 2000, in section 3 defines an “energy product” to include “an appliance powered by an energy source other than electricity or gas (such as solar, wind or water) or a component of such an appliance”. This was inserted into this act as an efficiency measure and not for safety reasons, and is not regulated by the Technical Regulator. The Technical Regulator is a statutory office established by Section 7 of the Electricity Act 1996. Robert Faunt has held this office since he was appointed as the Technical Regulator under the Electricity Act 1996 on 28 February 2003.

We have two functions. We make and amend the national electricity, gas and energy retail rules and conduct independent reviews for the COAG Energy Council. This work is copyright. The Copyright Act 1968 permits fair dealing for study, research, news reporting, criticism and review. Selected passages, tables or diagrams may be reproduced for such purposes provided acknowledgement of the source is included. Executive summary The eastern Australian gas market is experiencing a period of significant growth and change, as conventional gas reserves decline, unconventional gas resources become increasingly important and the influence of international prices trends increases. The establishment of a liquefied natural gas (LNG) export industry based in Queensland is triggering unprecedented shifts in supply and demand and, consequently, changes in patterns of gas flows. These factors are resulting in a renewed focus on market development and gas supply chain efficiency. Against this background, the COAG Energy Council has requested that the Australian Energy Market Commission (AEMC or "Commission") review the design, function and roles of facilitated gas markets and gas transportation arrangements on the east coast of Australia ("the East Coast Review").

  • WEEKLY GAS MARKET ANALYSIS 15 May – 21 May 2011
    WEEKLY GAS MARKET ANALYSIS 15 May – 21 May 2011 Preface As part of its monitoring roles for the National Gas Market Bulletin Board (Bulletin Board) and the Declared Wholesale Gas Market (Victorian Gas Market), the AER publishes a weekly gas market report. Part A of the report looks at gas usage and flows of registered facilities in southern and eastern Australia (as reported on the Bulletin Board). Part B provides a summary of operational and market data in the Victorian Gas Market. The AER is responsible for monitoring and enforcing compliance with Part 20 of the National Gas Rules (Gas Rules) that authorise and govern conduct in the Short Term Trading Market (STTM). The STTM is a market for the wholesale trading of natural gas at defined hubs between pipelines and distribution systems, and began operation on 1 September 2010. With initial hubs of Sydney and Adelaide, additional hubs are intended for the future. Each hub is scheduled and settled separately, but all hubs operate under the same rules. Part C provides a summary of operational and market data in the STTM. The Victorian Gas Market lies between the two STTM hubs and shares common production sources with the Adelaide and Sydney hubs. Participation in the Victorian Gas Market and the STTM hubs occurs on the basis of a different set of market rules and requires contractual arrangements with different pipeline owners. Participants operate in only those markets where they have production, gas and pipeline contracts. Some key differences between the STTM and the Victorian Gas Market are set out at the start of Part C.
