Project Background

A family in New South Wales, Australia, sought to maximize the use of their rooftop solar PV system to cope with high electricity prices (reaching up to AUD 0.50/kWh during peak periods) and grid instability.

Project Introduction

A 13.5kWh lithium iron phosphate residential energy storage system was installed, complementing their existing 10kW rooftop PV system. The system is CE certified and features virtual power plant (VPP) functionality, a prerequisite for applying for federal government subsidies.

The family successfully applied for the Australian federal government's "Cheaper Home Batteries" program, receiving a subsidy of AUD 3,000, while the New South Wales government also provided additional tax rebates.

User Feedback

"Government subsidies significantly reduced our initial investment burden. Our energy storage system has VPP functionality, and during peak summer electricity demand, we can choose to join the grid dispatch system as needed. This not only provides us with some electricity bill deductions but also contributes to grid stability, making us feel like our home is part of the larger power grid."

Subsidy Policy and Market Dynamics

The success of this case largely benefits from Australia's current strong policy support and market environment.

Strong Subsidies: The Australian Federal Government's "Cheaper Home Batteries" program, committing AU$2.3 billion, provides subsidies of up to AU$3,000 to households installing eligible residential energy storage systems. This directly stimulated users' enthusiasm for installation.
