Australia's largest home battery automation provider closes a €49 million Series E led by Morgan Stanley's 1GT, targeting European expansion via an existing E.ON partnership.
- Morgan Stanley Investment Management's 1GT led the €49M round; E.ON, ETF Partners, and Innovation Victoria co-invested.
- Amber holds more than 50% of Australia's automated home battery market and launched in the UK through E.ON Next in March 2026.
- The raise brings total disclosed equity funding to roughly $209 million across six prior rounds dating to 2019.

Amber Electric, the Melbourne-based wholesale energy retailer and battery automation platform, closed a €49 million (A$78.5 million) Series E on September 21, 2026. Morgan Stanley Investment Management's 1GT - the firm's climate-focused private equity strategy - led the round. E.ON, ETF Partners, and Innovation Victoria co-invested. It is the largest single raise in the company's nine-year history and the round closed nearly twice oversubscribed, per the company.
What Does Amber Actually Sell?
Amber is not a conventional electricity retailer. Rather than marking up a fixed or time-of-use rate, the company passes wholesale spot prices directly to customers and charges a flat monthly subscription instead. Its software layer, SmartShift, uses AI to forecast wholesale electricity prices, rooftop solar output, and household consumption in real time, then automatically charges or discharges home batteries when the economics favor it.
That model concentrates Amber's value in software arbitrage rather than energy margin. The company claims 50%-plus of Australia's automated home battery market - a position built by bundling its retail license with its optimization platform, a combination most competitors offer separately. A BYD-specific SmartShift product already has a waitlist of 8,000 customers, suggesting domestic demand has not peaked.
Why Is Morgan Stanley Putting Climate Capital Into a Retailer?
1GT's mandate is to back climate technologies where the commercial model is already working at scale. Amber's Australian business fits: subscription revenue is recurring, retail margins are thin but predictable, and the aggregated battery fleet creates optionality for selling grid-balancing services in wholesale markets.
Europe is a structurally similar bet. Retail electricity prices are high, home battery adoption is accelerating, and software for automated optimization remains fragmented. E.ON's presence in the cap table signals the strategic logic directly. The German utility's UK subsidiary, E.ON Next, launched a product called "Next Optimise" in March 2026, built on Amber's technology, giving UK households automated battery management without switching retailers. That B2B2C channel - licensing Amber's software to large incumbents - may prove more capital-efficient in markets where energy brand trust is sticky.
How Does This Round Compare to the Last?
The Series D in 2025 was A$45 million. This round at A$78.5 million is a 74% step-up in deal size within roughly 12 months. The company has not disclosed valuation, but the jump implies the board assessed that Australian market dominance and the E.ON Next UK launch warranted a materially higher price. Total equity raised since a $2.5 million seed in 2019 now stands at approximately $209 million - a substantial capital stack for a business whose core revenue is a monthly subscription fee.
That math looks better if Amber can replicate its Australian grid-services model in European balancing markets, where dispatchable distributed batteries command a premium. It is harder to justify if European growth depends on winning utility partnerships one at a time against a clock set by the company's burn rate.
What the Money Is For
Proceeds are allocated to product development, hiring, and market entry in additional European countries beyond the UK. Amber has not named specific geographies or set a public timeline. E.ON's operational footprint spans Germany, Sweden, the Netherlands, and several central European markets - a natural distribution path if the company can extend the E.ON Next relationship beyond Britain.
The commercial push is coming as European regulators move to mandate greater flexibility in retail electricity contracts, a structural tailwind that favors platforms capable of automated dispatch at the household level.
Outlook
Amber enters this raise with a defensible domestic position, a live European proof-of-concept, and a lead investor whose thesis matches the company's stated ambition. The key uncertainties are whether utility partnerships can replicate the customer density that organic retail growth delivered in Australia, and whether the subscription model generates enough margin to sustain a multi-market expansion before the capital runs out. A further raise within two years would suggest the answer to the second question is no.
