ENERGY MANAGEMENT


VPPs are a win-win for hospitals and our transforming grid ERH is providing what the Australian Energy Market Operator (AEMO) has stated is an urgent need for new forms of capacity on the power grid. VPPs are an obvious and cost-effective solution to this problem, and using existing assets means they can be built quickly, providing for a more efficient use of resources and avoiding the need to build expensive new gas peaking power plants. We are a small user, the VPP is about


a lot of ‘one per centers’ coming together to help out. I have been encouraging my colleagues to participate because most of our sites have generators and have to test them anyway, so we might as well run them and get paid for it. The benefit adds to other factors around


resilience and knowing your systems work, and you can use the income to improve your systems and other physical elements to ensure a reliable generation set. I know some have used their income


to increase the size of their fuel supply. Others have used it to install automatic switching or upgrade their PLCs. It is a win-win because the reliable capacity that we can provide to the grid is improved by putting the money back into improving the reliability of our own backup systems.
