As the body responsible for determining transmission system developments in Tasmania now and in the future, planning is an ongoing activity. Planning for where we want to go means looking back at how we've gone. Our Grid Vision program takes a long-term view of the electricity market in Tasmania and our relationships with the national market. Through the annual planning process, we analyse the performance of our system in minute detail including measures such as reliability, availability of plant and the number and nature of system incidents.
To see where the State is heading in terms of its growth and development, forecasts of electricity usage and demand are gathered from distribution company, Aurora Energy, and from other customers directly connected to our transmission system. The Australian Energy Regulator (AER) requires us to provide an overall assessment of the supply-demand balance in Tasmania for the next 10 years. We take it even further looking at demand forecasts for the next 15 years and the investment needed in the network over the next 30 years.
And we're getting better and better at looking at the big picture, particularly with issues like climate change and sustainability front and centre of the energy debate nationally and globally. We have to make sure we can continue to provide a safe, reliable and secure transmission service that meets customer expectations, both now and in the future.
