The AER confirmed on 28 September 2020 that: “…the AER considers that the updated cost benefit analysis provides a not unreasonable basis for ElectraNet’s opinion that PEC remains the preferred option. We expect both ElectraNet and TransGrid to submit full and complete contingent project applications for PEC as soon as possible.” On 29 September 2020, the ElectraNet Board approved submission of a contingent project application (CPA) based on the AER’s confirmation and the CPA was submitted to the AER on 30 September 2020. This note reviews several subsequently announced policies and other changes in the National Electricity Market (NEM) and considers the impact that these could have on the benefits of PEC.

The project is supported by the Australian Research Council and the following collaborative partners: Australian Tax Office, Commonwealth Office of Small Business, IBIS Business Information Pty Ltd., Productivity Commission, and Victorian Department of State Development. The views expressed in this paper represent those of the author and not necessarily the views of the collaborative partners.

The purpose of this paper is to discover whether there has been any change in the financial performance of government trading enterprises operating in electricity, gas, water, railways and ports industries as a result of these changes. There does not appear to have been a noticeable enhancement in the financial performance of most of these businesses, although railways have improved slightly, from a low base.

    Fuelling Tasmanian Jobs, Energy Security and Growth

    Fuelling Tasmanian jobs, energy security and growth. 1 The Tasmanian Gas Pipeline supports over 4,200 direct jobs and over 8,550 jobs in total, is crucial to Tasmania’s energy security and post-COVID economic recovery, and helps keep energy prices affordable for everyday Tasmanians. At a glance: • The TGP is the only mechanism by which natural gas is transported in bulk to Tasmania • The TGP is a significant enabler of economic activity in Tasmania, helping underpin the continued operation of numerous major industrial customers and the more than 4,200 direct Tasmanian jobs they support • It is the only supplier of gas to the Tamar Valley Power Station – an essential back-up power source for Tasmania which played a crucial role during the 2016 energy crisis, helping keep the lights on in Tasmania 4,200 Direct • Following COVID-19, the TGP provides an affordable jobs fuel source to drive Tasmanian manufacturing growth and the state’s economic recovery • It also provides affordable gas supply for Tasmanian businesses and households • Natural Gas provides the cheapest and most-efficient source of heat to Tasmanian Industry compared to diesel, fuel oil, LPG or coal, with low emissions • Ongoing connection of the Tamar Valley Power Station to the TGP will underpin Tasmanian energy security and ensure affordable gas supply to Tasmanian customers • The current four-year contract for the TGP to supply the Tamar Valley Power Station expires at the end of 2021 • An extension of this contract will provide energy security for Tasmania at least until other viable back-up power sources (such as Marinus Link) come online • Once Marinus Link comes online, the Tamar Valley Power Station can continue to provide grid and energy security services to support ongoing 8,550 renewables Total jobs 2 About the Tasmanian Gas Pipeline Commissioned in 2002, the Tasmanian Gas Pipeline • Adds $970m value (GSP) to the Tasmanian (TGP) is the only pipeline supplying natural gas to economy (three per cent of state’s total) Tasmania.
