Amber has closed a $45 million funding round to supercharge its growth and expand its battery and EV automation technology into global markets. The round was led by UK/Europe-based impact investor ETF Partners (The Environmental Technologies Fund), as well as participation from existing backers including Square Peg, Gentrack, Rubio Impact Ventures, and Breakthrough Victoria.
This investment builds on Amber’s strong momentum in Australia, where it has become the largest residential battery automation product in the market. With 40% of Australia’s new automated home batteries now taking advantage of Amber’s service, the company is showing how everyday households can take charge of their energy use and make money in the process.
This round of capital positions Amber to scale its operations and seize the opportunity presented as the battery market accelerates from 1 July 2025 in Australia, with the introduction of the federal government’s Cheaper Home Batteries Program rebate.
Developed in Australia - the world’s most advanced two-way energy grid - Amber’s technology is now scaling globally. With strong traction in its home market, the company has already signed deals with E.ON in the UK, one of the largest utilities in the UK and with Ecotricity, an environmental focused energy retailer, and is now focused on accelerating growth across Europe.
As utilities across the UK and Europe increasingly compete to provide compelling offers to home battery and EVs customers, Amber stands out for its customer-first approach, real-time automation, complete end to end product offering and proven success in Australia.
“We’re proving there’s a better way to do energy – with technology that puts customers at the centre of the energy transition,” said Dan Adams, co-founder and co-CEO of Amber. “This investment is a huge step forward in our mission to help households around the world take control of their energy, reduce costs, and support the energy transition”
“As more countries shift to decentralised, renewable energy, we’re excited to bring Amber’s model to the world stage – helping to build smarter energy systems everywhere.”
Amber gives customers access to real-time wholesale electricity prices and the technology to automate their home batteries and EVs to charge when cheap renewables are available, and to earn money by discharging when energy prices are spiking. Amber is now building its vehicle-to-grid (V2G) capability that will enable customers to benefit financially by selling energy from their EV back to the grid when it’s needed most.
"Amber is redefining how utilities and consumers interact with energy," said Rob Genieser, Managing Partner at ETF Partners. "Their technology not only optimises energy usage but also enables greater integration of renewables, paving the way for a more resilient and sustainable energy system. We want to back leaders driven by a strong sense of purpose, and Amber’s founders have demonstrated their commitment to transforming global energy markets for the better."
Amber’s international strategy includes licensing its technology through Gentrack’s global network of utility customers, offering bundled solutions that combine Gentrack’s billing and CRM systems with Amber’s automation software. This partnership positions both companies to meet rising global demand for customer-centric smart energy services.
With the Australian Government’s new battery subsidy set to boost local demand from July, and global momentum continuing to build behind clean energy, Amber is well positioned to become a key technology provider in the shift toward decentralised, consumer-led energy systems.
