The objective of this presentation is to cover the journey of integrating solar + storage into utility operations at the residential, commercial, and grid scales.Austin Energy, through the Austin SHINES (Sustainable and Holistic Integration of Energy Storage and Solar PV) Project, is integrating solar, energy storage, smart inverters, electric vehicles, forecasting tools, market signals and advanced communications through a utility integrated software optimization platform. Collectively, these technologies facilitate the integration of a renewable energy future and make the grid more resilient. The project includes solar plus storage integrations at the grid-scale, commercial, and residential levels as well as a vehicle to grid demonstration. The Distributed Energy Resource Management System (DERMS) uses control algorithms that realize market, reliability, and customer value propositions. Economic modeling work determines the differential value of holistically controlling Distributed Energy Resources. The project compares ownership and control methodologies – including utility-controlled, autonomous and third-party – to test and prepare for future use cases. Austin Energy was awarded $4.3 million from the U.S. Department of Energy and $1 million through the Texas Commission on Environmental Quality to support the initiative. Will we go through the methods to include the technical the aspects of integration, deriving value from this new system, barriers to deployment, and even the public input process with our customers. We will then present the results of our findings that are being reported back to the U.S Department of Energy to include demand charge reduction results, levelized cost of energy results, potential paths forward and how we have utilized our DERMS system for energy storage.
