Emaldo: Turning Energy Cost into Energy Profit

From the outside, Emaldo might look like another cleantech company with smart batteries and sleek apps. But a closer look tells a different story.

Over the years, it has evolved into a company that blends engineering precision with a distinctly Scandinavian sense of responsibility and user-centric simplicity. Headquartered in the quiet town of Ølstykke, Denmark, Emaldo is not simply helping people to participate in the Net Zero journey and maximise their solar energy. It’s helping them make money from it.

In just a few years since its founding in 2022, Emaldo has grown into one of the most talked-about names in home and business energy management across Northern Europe. The company’s technology has spread across Denmark, Sweden, Finland, the Netherlands, and the Czech Republic, connecting thousands of systems into what co-founder and co-CEO Steffen Bjerregaard calls “a living network of energy independence.”

That independence is more than a marketing phrase. It represents a fundamental shift in how people think about their power: when to use it, when to store it, and now, when and how to earn from it.
A Battery That Does More Than Store Power

The core of Emaldo’s appeal is its ability to make renewable energy work harder. For homeowners who either want to, or have already invested in solar panels, the company’s AI-integrated battery system adds a layer of intelligence that turns stored energy into a financial asset.

Most household battery setups allow users to store solar energy generated during the day and use it at during the hours when energy from the grid is the most expensive (typically in the mornings and afternoons), reducing their energy bills. But Emaldo goes a step further. Its systems can connect to national grid-balancing programs that pay customers for providing capacity and/or energy to help stabilize the electricity network.

It’s a simple idea, but extremely complex to execute. Since the second quarter of 2024, when the Emaldo Grid Rewards programme got underway, the company has paid out more than €10 million to customers so far. With the acquisition of Swedish tech firm CheckWatt, that number continues to climb, with around €2 million paid out every month. These payments are a tangible return on investment that customers receive directly into their bank account.

“People don’t just want to feel good about going green. They want it to make sense for their wallet,” says Bjerregaard. “Our mission is to make sure that it does.”

Value which Evolves with the Market'

Emaldo’s model is built around a concept that blends energy independence with profitability. When users install an Emaldo battery unit alongside solar panels, they start saving on two fronts: first, by consuming their own stored power during high-price hours, and second, by earning monthly grid rewards for supporting national energy networks.

This dual benefit means that, over time, the system can flip the usual energy-cost equation. In certain markets, like Denmark, where average electricity bills hover around 18,000 DKK a year, Emaldo customers have already begun reporting net-positive returns when their monthly rewards are added to their savings.

That kind of outcome is only possible because Emaldo’s technology is far from static. While many competitors sell batteries that remain unchanged after installation, Emaldo’s system evolves. Regular software updates introduce new optimization features, integrate fresh market mechanisms, and refine the AI’s learning. For users, this means the product they buy keeps improving, and so do their returns.

This is the difference between choosing a product and a solution. A product may be designed to solve a specific problem, and do that well, however a solution is designed to evolve and improve over time. As a result it is able to continually adapts and updates in response to changing market conditions to make sure Emaldo customers get the best returns from their investment.

Engineering for Longevity and Sustainability

Behind the scenes, the intelligence driving all this is the company’s proprietary AI system. Once installed, it begins a seven-day learning period, monitoring how the household or business consumes and generates energy throughout the day. It looks at when appliances are used, forecasts local weather and sunshine, and studies day-ahead electricity prices.

From that data, it creates a schedule that instructs the unit on the optimal times to charge and discharge the batteries. It knows when to prioritize self-consumption and when it’s more profitable to reserve capacity for the grid. The AI’s model isn’t static either; it constantly adjusts, refining its predictions as it receives new data. Manual overrides, such as someone deciding to run a heavy appliance at a different time, are fed back into the system, improving its accuracy over time.

The result is a setup that anticipates the customers rhythm and needs. It learns when the family wakes up, when the car is charged, and how sunlight shifts through the seasons. For users, it feels intuitive. For the grid, it’s a crucial stabilisation tool and as grid-scale generation becomes more intermittent and therefore less predictable.

Strength in Simplicity

One of the things that has helped Emaldo grow so quickly is how simple the end to end experience feels from both system owner and installer perspective.

Emaldo’s installation process has been created around the concept of making installs much easier and safer than with comparable systems, using a modular plug-and-play design, housed within a sleek, modern cabinet. Emaldo’s SlideON technology simplifies the internal wiring process by allowing the components to be slid into place without needing to connect wires initially. In addition, the cabinets are expandable, allowing for up to 3 power boxes within a single cabinet and easy parallel connections to add further cabinets.

Once installed, system owners can access a feature rich but intuitive user interface. The technology behind it might involve sophisticated forecasting and complex market participation, but for those customers, this all happens continuously and quietly in the background.

If solar production dips on cloudy days, the AI recognises this and will automatically decide whether to draw from the battery’s reserves or switch to grid power, depending on which option is most cost-efficient. In the event of a power cut, backup features keep essential devices running. The user doesn’t need to make any manual decisions unless they want to.

That balance of automation and control is intentional. Bjerregaard and his team wanted to build a product that empowered people without overwhelming them.

“There’s a difference between smart technology and complicated technology,” he explains. “We chose to make ours smart in ways that simplify life, not complicate it.”

Built for the Long Run

While AI and software define Emaldo’s brain, the company’s hardware forms its backbone. Its batteries use lithium iron phosphate (LFP) cells, a choice that emphasizes both safety and durability. With more than 6,000 full cycles at 80 percent depth of discharge, the average Emaldo battery can perform reliably for over fifteen years.

A ten-year performance warranty guarantees at least 70 to 80 percent of the original capacity at the end of that period. Because of the modular design, users can replace individual packs instead of entire systems. The company’s approach to maintenance mirrors its commitment to sustainability: efficient, predictable, and transparent.

When the batteries eventually reach the end of their life, Emaldo is in the process of developing a take-back program, to ensure that when batteries eventually reach the end of their life, certified recycling partners will ensure materials such as lithium, iron, and copper are extracted and reintroduced into the production chain, reinforcing the company’s alignment with circular economy principles.

A look at individual stories brings the technology to life. Danish actor Sebastian Jessen is one of Emaldo’s most visible advocates. Long committed to sustainability, Jessen had already invested in solar panels, an EV, and a heat pump. Yet despite these upgrades, his family’s electricity bills remained high, often between 35,000 and 40,000 DKK a year.

When he added an Emaldo battery to his system, the difference was immediate. Daytime solar energy that had once been exported cheaply to the grid was now stored and used in the evenings, when power was most expensive. His bills dropped sharply, and with annual grid rewards achieving up to 18,000 DKK, he began to see a net gain.

Responsible Partnerships

Behind every Emaldo product is a network of long-term, carefully chosen partners. The company works only with manufacturers that meet rigorous standards for environmental performance and quality assurance. Regular audits, third-party tests, and continuous monitoring through Emaldo’s internal testing centers ensure reliability never wavers.

It’s a strategy that also protects against market volatility. By maintaining multiple suppliers for each hardware category, Emaldo avoids single-source dependence and keeps pricing competitive. The company’s reputation for reliability is engineered into every part of its supply chain.

Emaldo continues to grow, recently expanding into the Commercial & Industrial sector through a strategic partnership with Zoe Energy Storage, and acquisition of Zoe Nordic. This move reflects the company’s steady evolution, forward thinking, and enduring commitment to advancing science and community health.

Even as Emaldo grows, it has resisted the temptation to centralize everything. Instead, it maintains local-language support in every market where its batteries are sold. Whether in Sweden, Finland, or the Netherlands, customers can reach a team that speaks their language and understands their local energy environment.

That philosophy extends to installation partners, who are given access to the same level of support as end users. The company’s network now includes more than 400 installation partners and over 100 electricity retailers. Together, they manage a growing fleet of more than 25,000 active devices and over 300 megawatts of controllable capacity across the Nordic region.

Beyond Batteries

Emaldo’s ambitions don’t stop with storage. The company’s roadmap includes smart consumption monitors, EV charge points, and heat pump integrations, all managed within the same AI platform. The vision is to turn homes into interconnected ecosystems where every energy device works in harmony to reduce waste and increase returns.

Some of these new technologies are expected to roll out by late 2025. When they do, they will mark Emaldo’s evolution from an energy storage company into something broader: a digital energy management brand that shapes how the modern home interacts with power.

Emaldo’s success is rooted in a simple truth: it offers customers a clear, measurable benefit while helping the planet. It allows people to control their energy, reduce costs, and get rewarded for supporting a greener grid.

As energy systems around the world become more decentralized, Emaldo’s model feels like a preview of the future. In that future, homes and businesses won’t just consume electricity. They will manage it, trade it, and profit from it, all while keeping the planet in balance.

“Our vision has always been about balance,” Bjerregaard says. “Between technology and people, between independence and connection, and between what we take from the grid and what we give back.”
