This document does three things. First, it outlines the of our customers and the consumers and communities we serve challenges we are likely to face in planning, operating and managing to ensure our services meet their long term needs. We know that the NSW electricity transmission network over the next 40 years. they want choice when it comes to their electricity and we believe Second, it provides an overview of the actions TransGrid is already that there shouldn’t be a trade off between choice and affordability, taking to meet those challenges. Finally, it sets out the Vision and sustainability and reliability. Principles that we’ll use to continue to deliver strong value to our customers and end users as we journey into that future. As we look to the future, to achieve this, TransGrid will demonstrate efficiency, responsiveness and innovation in everything we do and Our network is the centrepiece of the National Electricity Market this underpins our Network Vision.

It is one of the most reliable First, the fact that predicting the future isn’t easy only reinforces transmission networks in the world. the importance of continuing to engage with our customers and Taking a long view of the development of the network is important, stakeholders about what that future may look like and the challenges particularly now when the ways that we generate, transport and use we are likely to face in getting there. That dialogue forms an essential energy are undergoing rapid, significant change. There is a wide half of a virtuous circle: the better we understand our customers, range of opinions as to what that future may look like. Given the the more effectively we can plan, operate and deliver our network. uncertainties, this document isn’t an attempt to predict which one The more effectively we run our network, the more efficiently priced will come to pass. Nor is it a detailed planning document. Instead, capability we can offer our customers. the approach we’ve taken is to identify the features that those Second, we are already working hard to ensure that TransGrid scenarios about the future have in common. We will then discuss the as a business, and the transmission network itself, have the right characteristics our network will need to have to effectively play its capabilities.

Safe & reliable Customer choice Gerard Reiter Sustainable Affordable Executive General Manager/ Asset Management TransGrid Network Vision 2056 | 5 Executive summary Australia’s electricity industry is changing. There is a new smart and both networks and customers will deploy more advanced energy ecosystem developing. Customers will be at the heart of (“smarter”) information and control systems to better manage the that system, having a far greater say in how their power is provided delivery and consumption of electricity services, respectively. The and the grid will play an important and evolving role in meeting their pace of these trends will depend on a combination of economic, needs. This document sets out TransGrid’s Vision as to how the government policy and technology drivers. Whatever the specific NSW transmission network will do so over the next forty years and outcome, the future of energy supply is likely to be: the principles by which it will be planned, operated and managed to deliver that future. > More complex with the supply chain evolving from being a one way system with limited product choice to a “many to Viewed with suitable caution, trends can provide a starting point any” model where a mix of traditional and emerging providers, for understanding what that future may look like.
