Hornsdale Power Reserve Impact Study

Battery energy storage’s role in a sustainable energy future

Stabilising the electricity grid, facilitating renewable integration: technical and market impact studies on Hornsdale Power Reserve’s two years of operation.

The future of Australia’s rapidly growing renewable energy sector depends on addressing the issues of grid reliability and stability. As the energy market transitions to increasing penetrations of renewable energy, large-scale battery energy storage has the technical capabilities to achieve secure networks, reliable generation and a robust renewable grid of the future.

The Year 1 report details how, in its first year of operation, Hornsdale Power Reserve – owned and operated by Neoen, and supplied by Tesla – has delivered on the high expectations of its performance and market impact.

A new report released February 2020 analyses the performance of the world’s largest lithium-ion battery energy storage system and the value to the National Electricity Market following its second year of operation.

Aurecon’s latest report also provides analysis of the major network outage in Victoria on 16 November 2019 that caused the grid in the state of South Australia to “island” or become separate from the rest of the national electricity grid.

Year 2 Report – Technical and Market Impact Case Study

This report quantifies the market benefit of the presence of the Hornsdale Power Reserve on the National Electricity Market throughout 2019, compared with a modelling of what pricing would have been if it had not been present in the market.

Year 1 Report – Technical and Market Study

This report outlines how the battery technology has been used to achieve system security and reduce the risk of a system black event and load shedding, how it positively impacted ancillary service prices and created new commercial opportunities.

Batteries key in the future energy storage landscape

In this paper, Managing Director – Energy, Resources and Water Paul Gleeson explores the key lessons from the technical and market impact study for Hornsdale Power Reserve’s first year in operation.

He demonstrates how and why battery energy storage is an essential part of the mix required to ensure network reliability in a controlled transition to renewables.
