Amber has closed a $78.5 million Series E funding round to accelerate its growth in Australia and its expansion into global markets. The nearly twice oversubscribed round was led by 1GT, Morgan Stanley’s climate tech fund, with strong participation from existing backers Environmental Technologies Fund (ETF Partners), Innovation Victoria and E.ON.
This investment builds on Amber's momentum in Australia, where its technology was developed in the world's leading market for home battery uptake. Amber has become the largest residential battery automation product in the country, orchestrating more than half of automated home batteries in Australia.
“This additional capital positions Amber to double down on our expansion across Europe,” said Chris Thompson, co-founder and co-CEO of Amber.
“We’ve built the winning energy automation platform in Australia, and this funding will enable us to extend our leadership across Europe. Our partnership with E.ON is already showing what’s possible, and we’re excited to build on that momentum with more partners across the region.”
Amber gives customers access to real-time wholesale electricity prices and the technology to automate their home batteries and EVs, charging when cheap renewable energy is available and earning money by discharging when prices spike.
"We are pleased to partner with Chris and Dan to help accelerate Amber's next phase of development and support the broader transformation of electricity systems in Australia and Europe,” said Vikram Raju, Head of Climate Private Equity Investing at Morgan Stanley Investment Management and 1GT.
"We believe the company's innovative platform, talented team and clear strategic vision position it well to capitalize on the growing need for distributed energy solutions across global markets.”
Amber’s technology already underpins Next Optimise, E.ON Next's smart energy tariff and home battery and EV automation product, which launched in March 2026 and is now live for battery and solar households across the UK.
Amber is now releasing the next generation of this technology, including vehicle-to-grid (V2G) functionality, which is letting early customers earn money by selling energy from their EV back to the grid when it's needed most.
The opportunity to unlock more value for both energy consumers and utilities is attracting major partners across Australia and Europe, as the energy industry moves towards a smarter, more flexible energy system.
The $78.5 million investment will give Amber the capital to scale its technology in Australia, expand across European markets and continue investing in the products and infrastructure needed to put households at the centre of the energy transition.
