The Industrial Energy Efficiency Data Analysis (IEEDA) Project estimates the potential for energy efficiency improvement in different industrial sectors through quantifying the scale and value of untapped energy efficiency potential across a range of key technologies, processes and fuel types. The IEEDA project consolidates and analyses company data already collected through the Energy Efficiency Opportunities (EEO) Program, the National Greenhouse and Energy Reporting (NGER) system and a range of state based programs. The project also involved a detailed barriers-analysis to gain a better understanding of what may be preventing greater uptake of industrial energy efficiency projects. This will inform how these opportunities could be unlocked, and which policies may best achieve this. The Project has resulted in the construction of a comprehensive, national industrial energy use and energy savings dataset, based on real world data, which can be used to inform industry on areas of cost effective investment in energy efficiency as well as facilitating more prudent and informed government decision making. The Commonwealth will continue to update the IEEDA dataset with updated annual data and its integration with the IEEDA Tool. The most recent phase of the IEEDA project has included geospatial capability to allow for detailed geographical analysis of industrial energy use and energy supply data to support better management of future network demand and network growth.
