Ausgrid is the largest distributor of electricity on Australia’s east coast. We bring power to 1.7 million households and businesses across 22,275 square kilometres covering Sydney, the Central Coast and the Hunter Valley. Ausgrid plays a key economic role both nationally and in New South Wales (NSW), with our distribution network supplying electricity that powers the creation of 20% of our national and 59% of NSW’s Gross Domestic Product. 2 Ausgrid’s Regulatory Proposal 2019–2024 I believe our Proposal captures the significant progress Ausgrid has made so far to become a more customer centric organisation. Our customers want Ausgrid to provide network services which are affordable, reliable and sustainable. I want to recognise and thank our customers and stakeholders who have contributed both time and effort to helping the development of this proposal over the past two years. Your input has been influential in determining the final approach to our strategy, investment and the programs that are incorporated in the Proposal. Close engagement with our customers has underscored that affordable energy is particularly important. We understand that high energy prices are negatively impacting households and businesses alike. We have made inroads in addressing this and by 1 July 2018, Ausgrid’s network component of our customer’s bills will have reduced by 30% since July 2013. Specifically in relation to affordable energy supply, our Proposal will result in: y lower prices, with a 6% reduction in our prices within the network component of residential customer bills by 1 July 2019; y fairer prices, with changes to pricing that reflect the actual costs of network usage and measures to protect vulnerable customers; and y zero real growth in the value of the assets we use to provide our services on a per customer basis. This is only the start, as we will continue to keep downward pressure on our costs to support lower prices for customers. We are also committed to maintaining a reliable service to customers, whilst recognising that customers are often struggling under cost of living pressures. We will keep investment to a minimum, by only replacing ageing assets where there is no alternative and only augment to support targeted growth areas. We will continue to support growth in our economy with targeted infrastructure investment, for example in the Rozelle area to support transport growth and in Macquarie Park to support growth in the Information and Communication Technology sector. Additionally, rather than simply planning for more network infrastructure, we are looking first at where new technology, innovation (including demand management) and partnering with other companies and our customers will deliver supply at a lower cost. Our customers have also told us that they are interested in adopting more sustainable sources of energy and expect us to take action to facilitate the transition to a lower carbon economy. In response, our Proposal includes investments in a new technology platform that will support the transformation of our network from a passive one way distribution network to a smart grid that will more easily allow us to incorporate distributed energy resources and deliver the tools to better operate the network in real-time. I look forward to continuing to drive the company to achieve its vision over the coming regulatory period to be ‘a leading energy solutions provider, recognised both locally and globally’ and commit Ausgrid to continuing to work with our customers and stakeholders to deliver on this vision. We know from experience that we can only achieve our goals and purpose by working closely together. Your feedback on our Proposal is very welcome.

    NSW Infrastructure Capability Assessment Energy Baseline Report April 2012 This document is intended solely for the use and information of Infrastructure NSW Report Outline • Key Highlights • Introduction • Energy Industry Overview and Current Situation • Electricity • Gas 22 Key Highlights – Electricity • The majority of electricity generation and all transmission and distribution infrastructure assets in NSW are government owned • The NSW government recently privatised the retail electricity sector and announced plans to sell electricity generation assets • 82% (or 16,600MW) of electricity in NSW is generated by 4 key state owned corporations . Electricity is transmitted over a 12,000km transmission system and distributed over ~250,000km distribution system. The book value of this infrastructure is $34bn and the annual capital expenditure is around $4.5bn • Electricity infrastructure is planned through a number of national and operator network plans including the Electricity Statement of Opportunities, the National Transmission Network Development Plan, TransGrid's Annual Transmission Network Development Plan, the distributors Annual Network Development Plans and Performance Reports, and the 5-year Regulatory Proposals and Determinations by the Australian Energy Regulator • These reports provide evidence that, while a number of the state owned electricity distribution assets are beyond or approaching their standard design lives, electricity infrastructure appears to be in good condition and is capable of meeting demand • The performance of electricity generation, transmission and distribution infrastructure is monitored via a number of indicators. The NSW Government sets reliability and security standards through its Network licences. Key electricity operating licence performance indicators such as the average duration and frequency of interruptions have been improving over time • Electricity demand has been flat for the past 5 years partly due to slower economic growth, efficiency and in response to large price increases.

  • Energy Charter 2020 IAP Disclosure.Pdf
    2020 Disclosure Report to the IAP Leveraging high impact points to drive meaningful change for customers Message from our Chair The Energy Charter, starting to deliver The Energy Charter is a whole of sector initiative of 19 CEOs working together across electricity, gas and renewables to put customers at the centre of our businesses. We are not an industry body or a regulator – the Energy Charter is focused outward, on our customers, not on ourselves. We aim for “highest common denominator” – pushing each other to deliver for customers by promoting examples of best practice for signatories to adopt and collaborating in targeted groups to deliver specific projects through our #BetterTogether initiatives. Last year was foundational for the Energy Charter. In 2020, it is all about delivery: what is different and better for our customers because the Energy Charter exists? This has been an extremely challenging year for our customers, communities and signatories with bushfires, floods and the COVID-19 pandemic. However, with these challenges also come unique opportunities to better support Australians, to step beyond business-as-usual and demonstrate as a sector we are working together on the vision of the Energy Charter to “deliver energy for a better Australia”. REAL CHANGE FOR CUSTOMERS What have we done that has made an actual difference for the customer this year? My top three: 1. Stakeholders have told us that it is hard to get an overall picture of the level of customer service that the industry provides. In response, we have committed that each signatory will disclose their customer satisfaction scores.

  • Fees & Charges Additional
    ADDITIONAL FEES & CHARGES BEFORE & AFTER JULY 2019 A REPORT PRODUCED BY ALVISS CONSULTING FOR THE ST VINCENT DE PAUL SOCIETY VICTORIA DECEMBER 2019 For further information regarding this report, contact: Gavin Dufty Manager, Social Policy Unit St Vincent de Paul Society Victoria Phone: 03 9895 5816 or 0439 357 129 This report has been produced by: St Vincent de Paul Society Alviss Consulting www.vinnies.org.au/energy www.alvissconsulting.com 1. About this project This project has been undertaken to document and analyse the application of fees and charges to electricity retail contracts for residential consumers in NSW, Victoria, Queensland and South Australia before and after the introduction of the Victorian Default Offer (in Victoria) and the Default Market Offer (in other states) on 1 July 2019. Additional fees and charges applied to energy contracts can cause consumer detriment for two reasons: Firstly, additional fees and charges increase product complexity and the chance of consumers making poor decisions. Energy contracts are already complex products as consumers must understand their usage and needs when comparing offers. Additional fees and charges add another layer of complexity to this process and as some fees are linked to consumer behaviour or future decisions (e.g. late payment fees and early termination fees) it can be almost impossible to determine what offers are most suitable in the long run. Secondly, significant additional fees and charges can make up a substantial proportion of many households’ energy costs, particularly for low consumption households. This is problematic in a reform environment based on demand side participation where consumers are expected to take greater responsibility to reduce their energy costs.

  • The Tomago to Stroud 132 Kv Transmission Line: a Surveying Mixed Bag
    Proceedings of the 18th Association of Public Authority Surveyors Conference (APAS2013) Canberra, Australian Capital Territory, Australia, 12-14 March 2013 The Tomago to Stroud 132 kV Transmission Line: A Surveying Mixed Bag Adam Long TransGrid [email protected] ABSTRACT The 66 km Tomago to Stroud 132 kV transmission line project undertaken by TransGrid was a good opportunity for its survey group to showcase their spatial skills and knowledge and apply them to many facets of the project. Using numerous sources of survey and spatial data, the survey group delivered a homogenous, quality product that provided stakeholders with the information they needed whilst staying within critical time and cost constraints. The TransGrid survey group analysed and overlayed spatial data from many sources such as Airborne Laser Scanning (ALS), the Digital Cadastral Database (DCDB), aerial photography, SCIMS and field surveys to provide relevant accurate information to designers, land economists, land valuers and project managers. Based on this information a design was handed back, and the TransGrid survey group created route plans and set out the proposed structures, in effect ‘testing’ the design. This was an iterative process that refined the design to the ‘for construction’ stage. To protect this piece of infrastructure and to ensure the project progressed in a timely manner, easements had to be surveyed and created prior to construction. The survey of easements proved to be both interesting and testing from a boundary definition perspective with the new transmission line crossing through many old portions of limited title and definition. The TransGrid survey group took a ‘whole of project’ approach when tasked with the planning, investigation and delivery of spatial data services.
