Morgan Stanley Investment Management's 1GT climate-focused private equity strategy has led a €49 million Series E funding round for Amber Electric, an Australian company that makes software to automate home batteries. The fresh capital will support Amber's expansion into European and US markets, according to a statement from the firm.
Amber's platform is designed to make home batteries work smarter. Instead of simply storing solar power for later, the software decides when to charge and discharge based on real-time electricity prices. When power is cheap—often in the middle of the night or during periods of high renewable generation—the battery charges up. When prices spike, typically in the evening when demand peaks, the battery discharges to power the home or even exports electricity back to the grid.
That individual optimization is useful for households, but the bigger opportunity lies in scale. When thousands of batteries are coordinated together, they can act as a single "virtual power plant." This aggregated resource can help grid operators meet demand during peak hours without firing up expensive and polluting backup plants. It can also absorb excess renewable power when supply outstrips demand, reducing the need to curtail wind or solar farms.
Why this funding round matters
The investment from Morgan Stanley's 1GT strategy—which focuses on companies that can help reduce greenhouse gas emissions—signals growing institutional interest in the "distributed energy" space. Rather than building large centralized power plants, investors are increasingly backing software and hardware that make the existing grid more flexible.
Amber's expansion into Europe and the US comes at a time when both regions are pushing to electrify homes and integrate more renewables. Europe has seen a surge in home battery installations, driven by high electricity prices and policy support. In the US, states like California and Texas are grappling with grid reliability issues, and home batteries are being promoted as a way to reduce strain during extreme weather events.
The company's model is also notable because it relies on dynamic pricing. In markets where electricity prices fluctuate by the hour, consumers can save money by shifting their usage. Amber's software essentially does this automatically, which could make it more appealing to households that don't want to manually monitor prices.
What it means for investors
For everyday investors, this deal is a reminder that the energy transition is not just about solar panels and electric vehicles. Software that optimizes energy use is becoming a key piece of the puzzle, and private equity firms are placing big bets on it.
Morgan Stanley's involvement is noteworthy because it ties into the firm's broader push into climate investing. The 1GT strategy, which stands for "1 Gigaton," aims to help companies avoid or remove one billion metric tons of greenhouse gas emissions by 2050. This is part of a larger trend among asset managers to launch funds that target environmental outcomes, even as some have pulled back from ESG labeling due to political pressure.
For those watching the public markets, this funding round could be a precursor to an eventual initial public offering. Many private companies in the clean energy space have used late-stage funding to scale before listing. However, there is no indication that Amber is planning an IPO anytime soon, and the company has not disclosed its valuation.
Investors should also note that home battery software is a competitive field. Established players like Tesla and Enphase offer their own battery management systems, and utilities are developing their own demand-response programs. Amber will need to differentiate itself through its pricing intelligence and ability to work across different battery brands.
The broader takeaway is that the energy grid is becoming more decentralized, and software is the glue that makes it work. As more homes adopt batteries, the value of companies that can orchestrate them will likely grow. But as with any early-stage technology, there are risks—including regulatory changes, market adoption rates, and competition.
For now, the €49 million injection gives Amber the runway to test its model in new markets. Whether it can replicate its Australian success abroad remains to be seen, but the backing from a major asset manager like Morgan Stanley is a vote of confidence in the idea.
