It is the authors view that the proposed development is in conflict with the Schedule 1 objectives of the Resource Management and Planning System of Tasmania. The development impacts negatively on the people and communities and does not provide for or maintain their current level of social, economic and cultural well-being and for their health and safety. Blackstone Heights is significantly, a low density housing community. People invest and live in this area for the amenity that is provided by that zoning. This is not a zoning that was forced on the community, residents made the free choice to live here. The proposed zoning change alters that and will have long lasting impacts on the social, economic and environmental amenity of residents. The proposal supporting the application for the creation of the Blackstone Heights Specific Area Plan is flawed and does not support the requirements that the proposed amendment

  • 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.

Brandner 1 1 Australian Maritime College, University of Tasmania, Launceston 7250, Tasmania, Australia; [email protected] (J.M.W.); [email protected] (P.A.B.) 2 School of Engineering & ICT, University of Tasmania, Hobart 7005, Tasmania, Australia; [email protected] * Correspondence: [email protected]; Tel.: +61-3-6324-9489 Academic Editor: K.T. Chau Received: 24 February 2017; Accepted: 31 March 2017; Published: 7 April 2017 Abstract: The increase in contributions from non base load renewables, such as wind and solar, can have adverse effects on the stability of an electrical grid. In this study, the possibility of rapidly loading a Francis turbine from a tail water depression (TWD) mode for providing additional system frequency control is investigated. Based on the analysis of full-scale TWD test results and key findings from the transient testing of a micro-hydro scale turbine unit, a detailed description of the TWD transition process is given. The formulation of an improved turbine model for use in one-dimensional hydro-electric plant models is presented with simulation results compared to full-scale data. The analytical model, which calculates output power according to the conservation of angular momentum and identified sources of loss, is used in parallel with full-scale and model scale test observations to elucidate the events and mechanisms occurring during this proposed transition. The output response, in terms of active power, was found to be highly dependent on guide vane opening rate in both full-scale and model tests.

  • Water Management in the Anthony–Pieman Hydropower Scheme
    Water management in the Anthony–Pieman hydropower scheme Pieman Sustainability Review June 2015 FACT SHEET Background The Anthony–Pieman hydropower scheme provides a highly valued and reliable source of electricity. The total water storage of the hydropower scheme is 512 gigalitres and the average annual generation is 2367 gigawatt hours. Construction of the Anthony–Pieman hydropower scheme has resulted in creation of water storages (lakes) and alterations to the natural flow of existing rivers and streams. The Pieman Sustainability Review is a review of operational, social and environmental aspects of the Anthony–Pieman hydropower scheme that are influenced by Hydro Tasmania. This fact sheet elaborates on water management issues presented in the summary report, available at http://www.hydro.com.au/pieman-sustainability-review Water storage levels in the Anthony–Pieman Water levels have been monitored at these storages since hydropower scheme their creation in stages between 1981 and 1991. The Anthony–Pieman hydropower scheme includes eight Headwater storages: Lake Mackintosh and Lake water storages, classified as headwater storages (Lakes Murchison Mackintosh and Murchison), diversion storages (Lakes Lakes Mackintosh and Murchison are the main headwater Henty and Newton and White Spur Pond) and run-of-river storages for the Anthony–Pieman hydropower scheme. storages (Lakes Rosebery, Plimsoll and Pieman). Lakes The water level fluctuates over the entire operating range Murchison, Henty and Newton and White Spur Pond do not from Normal Minimum Operating Level (NMOL) to Full release water directly to a power station; rather they are Supply Level (FSL) (Figures 1, 2). used to transfer water to other storages within the scheme.

  • Implications for Tasmanian Electricity System of The
    Backroad Connections Pty Ltd ABN: 64 090 245 382 [email protected] (0407) 486-651 www.backroad.com.au Implications for the Tasmanian electricity system of the proposal to restore Lake Pedder July 2019 Overview The paper analyses the implication for the Tasmanian electricity system of the proposal by the Lake Pedder Restoration Committee (LPRC) to restore the original Lake Pedder. It provides information on the current contribution of the Gordon Scheme to Tasmanian electricity generation and energy storage and provides some information and estimates on alternatives to replace this generation if the original Lake Pedder was restored. Background The original Lake Pedder was flooded in 1972 as part of an expansion of the Tasmanian hydro-electric scheme. The flooded area created is still officially known as Lake Pedder although the LPRC prefer the name Huon- Serpentine Impoundment. In this paper we will use the term ‘new Lake Pedder’. The new Lake Pedder at 242 sq km is vastly bigger than the original Lake Pedder at 10 sq km. The new Lake Pedder does not have its own hydro-electric generation. Its purpose is to trap and raise the level of the water that would otherwise flow down the Huon and Serpentine rivers. The water is raised to the level where it flows through a channel created at McPartlan Pass into the Gordon Dam and contributes to the storage and generation of the Gordon Scheme. As a result the level of the new Lake Pedder does not vary more than a few metres. This makes it more visually attractive and more suitable for recreational use than the adjacent Gordon Reservoir.

  • Hydro 4 Water Storage
    TERM OF REFERENCE 3: STATE-WIDE WATER STORAGE MANAGEMENT The causes of the floods which were active in Tasmania over the period 4-7 June 2016 including cloud-seeding, State-wide water storage management and debris management. 1 CONTEXT 1.1 Cause of the Floods (a) It is clear that the flooding that affected northern Tasmania (including the Mersey, Forth, Ouse and South Esk rivers) during the relevant period was directly caused by “a persistent and very moist north-easterly airstream” which resulted in “daily [rainfall] totals [that were] unprecedented for any month across several locations in the northern half of Tasmania”, in some cases in excess of 200mm.1 (b) This paper addresses Hydro Tasmania’s water storage management prior to and during the floods. 1.2 Overview (a) In 2014, Tasmania celebrated 100 years of hydro industrialisation and the role it played in the development of Tasmania. Hydro Tasmania believes that understanding the design and purpose of the hydropower infrastructure that was developed to bring electricity and investment to the state is an important starting point to provide context for our submission. The Tasmanian hydropower system design and operation is highly complex and is generally not well understood in the community. We understand that key stakeholder groups are seeking to better understand the role that hydropower operations may have in controlling or contributing to flood events in Tasmania. (b) The hydropower infrastructure in Tasmania was designed and installed for the primary purpose of generating hydro-electricity. Flood mitigation was not a primary objective in the design of Hydro Tasmania’s dams when the schemes were developed, and any flood mitigation benefit is a by-product of their hydro- generation operation.

  • A Review of Geoconservation Values
    Geoconservation Values of the TWWHA and Adjacent Areas 3.0 GEOCONSERVATION AND GEOHERITAGE VALUES OF THE TWWHA AND ADJACENT AREAS 3.1 Introduction This section provides an assessment of the geoconservation (geoheritage) values of the TWWHA, with particular emphasis on the identification of geoconservation values of World Heritage significance. This assessment is based on: • a review (Section 2.3.2) of the geoconservation values cited in the 1989 TWWHA nomination (DASETT 1989); • a review of relevant new scientific data that has become available since 1989 (Section 2.4); and: • the use of contemporary procedures for rigorous justification of geoconservation significance (see Section 2.2) in terms of the updated World Heritage Criteria (UNESCO 1999; see this report Section 2.3.3). In general, this review indicates that the major geoconservation World Heritage values of the TWWHA identified in 1989 are robust and remain valid. However, only a handful of individual sites or features in the TWWHA are considered to have World Heritage value in their own right, as physical features considered in isolation (eg, Exit Cave). In general it is the diversity, extent and inter-relationships between numerous features, sites, areas or processes that gives World Heritage significance to certain geoheritage “themes” in the TWWHA (eg, the "Ongoing Natural Geomorphic and Soil Process Systems" and “Late Cainozoic "Ice Ages" and Climate Change Record” themes). This "wholistic" principle under-pinned the 1989 TWWHA nomination (DASETT 1989, p. 27; see this report Section 2.3.2), and is strongly supported by the present review (see discussion and justification of this principle in Section 2.2).
