In this environment, network businesses need to ensure both large-scale and small- scale generation assets are connected safely and reliably, while continuing to provide customers sustainable prices. While the surge of customers installing solar provides them greater control over their energy usage, it creates challenges for managing our network. It means the system needs to facilitate power flowing both to and from local premises with generation and storage assets. Over the past five years of TasNetworks, we have been working to create a future electricity grid that enables us to keep prices down, keep the lights on and to leverage our unique position in the National Energy Market (NEM). We have been building capabilities and trialling new systems to ensure network design delivers benefits. This includes the Bruny Island Battery Trial, with the objective to improve ways of network management using distributed energy storage, improve the autonomous operation of energy storage and investigate the social aspects of tariff structures. The trial provides a glimpse into a future electricity network where everyone can benefit. This year we released our Marinus Link Initial Feasibility Report, which demonstrates a second Bass Strait interconnector would provide NEM-wide economic benefits, including the transition to a future of lower carbon emissions. Marinus Link would enable AnnualAnnualReportReport 20182018--1919 5 We continue to see unprecedented enquiries Lance Balcombe. With the strong support of for new renewable generation developments the entire TasNetworks team the company to connect to the transmission network.

Once again, robust consideration of social and environmental impacts and careful community consultation are critical. This is particularly important as we plan the transmission developments to enable the connection of large-scale renewable energy in the North-West. The Australian Energy Regulator (AER) allowed TasNetworks revenue of $2,012.5 million for the 2019-24 period. I wish to acknowledge the customers and stakeholders that worked with us to develop a proposal that ensures TasNetworks is appropriately equipped to address the challenges of a rapidly changing industry, while continuing to provide the affordable, safe and reliable services our customers expect. I would like to acknowledge the work of my fellow Directors, particularly retired Director Dr Jane Sargison for her service to TasNetworks and great contribution to the Board and committees. Following Jane’s retirement, we welcomed Dr Julie Beeby to the Board and also appointed an additional director, Sarah Merridew. Both Julie and Sarah have a wealth of experience and are providing valuable leadership, insight and knowledge to the Board. During 2018-19, TasNetworks had many accomplishments. I am particularly proud of our ability to face new technical and operational challenges head on and our involvement in leading Australia’s renewable energy future. We look forward to working closely with our customers and the community on both challenges and the opportunities that present us in the years to come. I specifically acknowledge the commitment of the TasNetworks Leadership Team led by AnnualReport 2018-19 6 FROM THE CEO The 2018-19 year was another successful year for TasNetworks, culminating with the celebration of our five-year anniversary. We can be proud of the efforts of our entire team who continue focus on delivering valuable services and outcomes to our customers, our owners and our community. A shining example of this was our response to January’s devastating bushfires that burned on many fronts across Tasmania. Our team participated in a massive collaborative effort with the fire and emergency services, the Australian Energy Market Operator (AEMO), Government agencies, the Bureau of Meteorology and local communities to coordinate a safe response, protect our key transmission and distribution assets while working hard to maintain energy system security across Tasmania at a time when it was very much needed. Fortunately, our assets losses were reasonably low, particularly for the business while also providing improved in comparison to those under threat, and customer outcomes. Combined, the two the restoration efforts from our team and elements

  • Hydro Tasmania Submission
    Response to Draft Determination on the Tasmanian Derogations and Vesting Contract dated 18 July 2001 Hydro Tasmania Submission 1. Introduction 1.1 The timely release of the ACCC's draft determination is a positive step towards Basslink and Tasmania's entry into the National Electricity Market (NEM). 1.2 Hydro Tasmania welcomes this opportunity to put forward its views. This is the first opportunity Hydro Tasmania has had to interface directly with the ACCC on these authorisations. 1.3 The conclusions on the vesting contract and the derogations are balanced outcomes which are good for Tasmania. They represent a sound basis for Tasmania to enter into the NEM as a single region. 1.4 This is an evolving market and the rules are changing day by day. 1.5 Tasmania's electricity industry is undergoing significant and complex structural changes which are moving forward at a rapid pace. Simultaneously, Tasmania's gas industry is developing. Hydro Tasmania would like to share its perspective on these developments based on the significant work it has undertaken, its role in supporting key projects such as Basslink and the important role it and these projects will play in the NEM. 1.6 Hydro Tasmania brings to the NEM a huge renewable and peaking resource previously denied to mainland Australia. This resource has always been there but historical State electricity structures meant it remained locked away. Now Basslink builds upon the competition reforms which the ACCC has overseen within the industry, enabling this resource to be unlocked and fully utilised. 1.7 Basslink also enables Tasmania's additional renewable potential to be brought into the NEM.

  • RE: EPR0059 - Frequency Control Frameworks Review
    5 December 2017 Australian Energy Market Commission (AEMC) PO Box A2449 Sydney South NSW 1235 Dear Mr Pierce, RE: EPR0059 - Frequency Control Frameworks Review Tasmanian Networks Pty Ltd (TasNetworks) is pleased to provide our response to the Issues Paper – Frequency Control Frameworks Review which was published by the AEMC on 7 November 2017. As the Transmission Network Service Provider (TNSP) and Distribution Network Service Provider (DNSP) in Tasmania, TasNetworks is focused on delivering safe and reliable electricity network services while achieving the lowest sustainable prices for Tasmanian customers. We are committed to ensuring the secure operation of the Tasmanian power system while seeking new and innovative ways to extend the capability of our networks. This includes pursuing solutions that will support an increased penetration of intermittent renewable generation in Tasmania. We contributed to the development of, and fully support, the Energy Networks Australia submission. The purpose of this submission is to highlight key issues that have particular relevance in the Tasmanian region as well as provide commentary on a number of technical matters pertaining to network frequency control. Given the nature of the Tasmanian power system, frequency control has always been a significant consideration for the design and operation of our network. It has dictated the need for differing Frequency Operating Standards (FOS) and the development of innovative solutions, including the implementation of fast acting System Protection Schemes

We have some of the best water and wind resources in the world that are helping us build a renewable energy industry for the future. We are doing so well that we will soon be producing enough renewable energy for all of the houses and businesses in Tasmania. It means Tasmanians will be able to say our electricity is 100 per cent renewable. That’s a record for Australia and up there with only a handful of countries around the world. Not only is it great that Tasmania will soon be producing enough clean renewable energy for all Australia’s energy industry is also changing. As a Tasmanians, but we can produce even more.
