Study calls for coordinated approach to embedded power generation

A year-long study initiated by Energy Networks Association (ENA) in conjunction with the CSIRO, which focuses on the benefits and impacts of embedded generation on energy networks, was released at the ‘Energy State of the Nation’ conference in Sydney. This study expands on earlier work commissioned by CSIRO in 2008.

Speaking at the ESON Forum, ENA Chief Executive Andrew Blyth said: “This comprehensive study looks at all types of embedded generation from domestic solar photovoltaic (PV) cells to large-scale wind farms and the effects these have on the grid under a wide range of scenarios. The study also provides the industry with an increased understanding of the potential benefits and impacts of embedded generation, as well as allowing network businesses to better prepare for higher penetration of renewable energy sources.

“Importantly, this report also provides industry, regulatory and government stakeholders with an insight into some of the issues associated with the increasing abundance of embedded generation, particularly solar PV, on the Australian electricity distribution network. This is the first comprehensive analysis of scenarios specific to Australian network conditions with real-world data in order to identify and help overcome issues that have been previously unrecognised.

“Another important outcome from this project is a comprehensive and practical report for ENA members to use in developing strategies, operational plans and staff training material that will assist in the future development of the distribution network.

“Specifically, the study will allow distribution network businesses to better plan and design their grids to cope with the uptake of renewable generation technology. This has been done through modelling a range of different embedded generation scenarios.

“There are a host of potential benefits for embedded generation, many of which will require technical issues to be addressed and this will likely require augmentation or other forms of network investment. It is also important to note that the study has identified a number of issues that require solutions to ensure that customers’ expectations for the safety, reliability and quality of power continue to be met.

“If the industry and key stakeholders take into consideration the findings in this report, there is a great potential for a significant increase in the uptake of renewable energy as well as substantial savings in network investment required to meet peak demand. This would be facilitated through all stakeholders having a greater understanding of the overall impacts of embedded generation under certain scenarios and the issues that need to be addressed to ensure that the move towards renewables happens in a coordinated, efficient and cost-effective manner.”
