Fusebox continues to scale up grid flexibility across the Baltics. We recently prequalified an additional 2 MW of mFRR up capacity and 1 MW of mFRR down capacity in Estonia, strengthening our commercial and industrial portfolio and adding a new BESS-specific portfolio. At the same time, we successfully added another 1 MW of mFRR up capacity in Lithuania, reinforcing our presence in a high-value market where mFRR prices are approximately three times higher than in Estonia.

“Growing our portfolio is one thing. Making sure every single megawatt can deliver on command is where the real challenge and value lies,” says Donatas Braziulis, Head of Portfolio at Fusebox.

Estonia: Tested, Verified, Activated

The Estonian prequalification process was conducted by Elering, Estonia’s transmission system operator. The test simulates real market conditions. Assets must respond to a 15-minute activation signal by reaching full output in 5 minutes, remaining stable for at least 10 minutes, and returning to baseline once the signal ends.

For instance, if a portfolio starts at 0 MW and is dispatched to -3 MW (feeding power into the grid), it must return to 0 MW afterward. The test is closely monitored to ensure genuine responsiveness.

“We passed on the first attempt. That speaks to how mature our platform is. Running the test is the easy part. The challenge lies in the months of technical and regulatory preparation behind the scenes,” says Donatas.

We now operate two mFRR up portfolios in Estonia:

• A 1 MW residential portfolio designed for private customers who trade on higher price volatility
• A 3 MW commercial and industrial portfolio composed of batteries, generators, PV systems, and industrial loads

These portfolios can now be activated up to 20 times per day, enabling over 2.1 GWh of traded flexibility each month across Estonia and Lithuania.

Lithuania: High-Value Market, Strong Entry

Fusebox also achieved prequalification for an additional 1 MW in Lithuania, where regulatory market prices are currently about three times higher than in Estonia. This gives our team a powerful entry point into a market where flexible capacity can deliver stronger returns with each activation.

“Lithuania offers a great environment to show the real-world value of flexibility. It’s also an excellent use case for potential SaaS clients who want to see a portfolio already trading, not just theory. It’s always easier to sell results than promises,” says Donatas.

This move not only diversifies our regional presence, it also reinforces our ability to operate effectively across different regulatory and market frameworks.

What’s Next

We’re continuing to grow. Plans are already underway to further expand both our mFRR up and down portfolios in Estonia and Lithuania, with more megawatts in the pipeline and new client assets being onboarded every month. In parallel, we’re also working on launching our first aFRR portfolio, opening up a new chapter in real-time balancing services for our partners.

“We’re not just adding megawatts. We’re building responsive, revenue-generating portfolios that support the grid and prove the commercial value of flexibility,” says Donatas.

Fusebox continues to unlock real-time flexibility for TSOs and asset owners through proven technology, efficient operations, and market-ready capacity.

Until now, battery owners paid grid fees twice: once when charging from the grid and again when discharging energy back into it. This setup severely impacted margins, especially for smaller commercial systems where grid costs could consume up to a third of total earnings. With the new rules, this penalty is gone, provided that the battery has a dedicated metering point and does not share it with any other consumption. In short, one energy flow now means one grid fee.

€12 Million Reasons to Celebrate

Let’s look at the impact. If Estonia installs 500 MW of storage, operating 2,400 hours per year at 80% efficiency, operators could save up to €12 million annually by avoiding duplicate grid charges. For C&I projects, behind-the-meter storage, and EPCs, this shift means shorter paybacks, better returns, and stronger financial viability for projects that previously didn’t make sense.

Not Just Estonia

The issue of double charging isn’t unique to Estonia. Across Europe, many countries still apply both consumption and injection fees to battery storage. This outdated approach treats batteries as both energy consumers and producers, discouraging investment. Some countries have already started correcting this. Ireland eliminated generation-related charges for storage, Germany and Spain introduced targeted exemptions, and the Netherlands is reforming grid pricing to reduce overall fees. Despite these improvements, several EU Member States still maintain billing structures that penalize energy storage rather than support it.

A Smarter Way to Meter

Estonia’s reform also updates the way energy is measured. Previously, DSOs (Distribution System Operators) calculated demand and generation separately for each phase. As a result, even well-balanced systems could end up paying twice within the same billing period. Under the new model, power flows are first summed across all three phases and then categorized as either consumption or generation. This approach is not only simpler but also far more accurate and in line with how modern batteries interact with the grid.

What Comes Next?

While this reform improves project economics, it also removes one source of income for the grid. Balancing costs in Estonia have risen since desynchronization from the Russian grid, and there may be future efforts to recover those costs through other mechanisms. Even so, this legislative change sends a strong signal. It removes a key barrier to storage investment and aligns Estonia’s billing practices with the realities of a modern, flexible energy system.

Double charging is being phased out. Fusebox is ready. Are you?

With a properly integrated Energy Management System (EMS), these sites could cut energy costs by up to 40 percent. That’s €871,840,000 in savings currently being missed every year.

The impact goes beyond money.

By improving PV productivity by up to 15 percent and storing excess solar energy in batteries, Fusebox EMS allows sites to discharge clean energy during morning and evening peaks when fossil fuel plants are still powering the grid. This shift alone could remove more than 30 million tons of CO₂ emissions annually across Europe.

Smart hardware is everywhere. Smart systems are not

Modern energy sites are packed with intelligent components. Batteries, inverters, EV chargers, and heat pumps all offer advanced capabilities. But without a central system to bring them together, they operate in silos. EPCs often spend valuable time connecting incompatible technologies. OEMs see their high-performance products fall short in the field. And clients are no longer satisfied with simple monitoring. They want results they can measure, control they can trust, and a return on investment they can show.

Fusebox EMS solves the problem at its core

Fusebox EMS brings all on-site energy assets together into one intelligent control system. It connects PV, BESS, EV chargers, heat pumps, and more. The system integrates with existing hardware, handles complex setups, and enables real-time control, forecasting, and participation in energy markets.

The results speak for themselves
• Up to 40 percent reduction in energy costs
• Up to 15 percent increase in PV output through better utilization
• 30 to 50 percent faster deployment by simplifying integration
• New revenue streams from flexibility and energy trading

Whether you are delivering turnkey systems or supplying key components, Fusebox EMS helps you deliver more value, improve performance, and scale with confidence.

The post The €871 Million Opportunity EPCs and OEMs Are Overlooking appeared first on Fusebox.

Raido Seppam, EMS Commercial Development Manager at Fusebox, explains:

“I’ve spoken with hundreds of asset owners and EPC companies about their energy projects, and a clear pattern emerges. Managing hybrid sites with renewable generation, local storage, and onsite consumption is complicated. Optimizing renewable output, turning storage into an additional revenue stream, aligning consumption with volatile energy prices, and selling excess energy back to the grid, all without exceeding connection limits, is already challenging for single sites. EPC companies have it even tougher, often managing multiple sites across regions with different rules. Fusebox EMS was specifically built to simplify exactly this kind of complexity.”

How Fusebox EMS Makes Your Life Easier:

Fusebox EMS brings all your energy assets: solar panels, wind turbines, batteries, and EV chargers, into one system. It connects easily using standard protocols, giving you full control without the usual complexity. It automatically stores excess renewable energy so nothing goes to waste. This boosts energy efficiency, increases profitability, and reduces your reliance on grid imports.

Your battery storage becomes more than just backup. Fusebox EMS turns it into a revenue-generating asset by charging when prices are low and discharging when they spike. Some users are making over €31,000 annually just from this alone. It also cuts your energy costs by adjusting onsite consumption based on real time market prices. No manual effort needed. To top it off, Fusebox EMS keeps your site within grid limits at all times. That means no penalties, no stress, and full compliance.

And if you’re managing more than one site? No problem. The platform scales easily across multiple locations and regulatory zones, giving EPCs and asset owners clear, centralized control.

Proven Results in Action

Fusebox EMS delivers real, measurable impact:

• Up to 40% energy bill savings through intelligent load shifting and consumption optimization
• 50% lower tariffs by reducing grid reliance during peak hours
• 0 € in negative price penalties thanks to smart curtailment and battery coordination
• 20% higher PV output by storing excess production instead of curtailing it

Fusebox EMS is your partner in tackling today’s complexity while preparing you for tomorrow’s opportunities.

The post Raido Seppam: The One Pain Point All EPCs Share appeared first on Fusebox.

In conversations with our EPC clients across Europe and beyond, one thing has become clear: EMS is not just enhancing project outcomes, it is redefining what success looks like. Here is a snapshot of the impact companies are already seeing:

 Key Numbers at a Glance

• 32% OPEX reduction guarantees included in project proposals (FRV Mexico case study)

• 15% faster commissioning enabled by pre-configured smart controllers

• €25,757/year per client from automated energy arbitrage

Modern EPC companies are under growing pressure to deliver smarter, future-ready projects. Fusebox’s EMS platform plays a critical role in making that happen.

EPCs that adopt Fusebox technology can now confidently include OPEX reduction guarantees of up to 32% in their proposals, giving them a clear competitive advantage, a strategy successfully proven in projects like FRV Mexico. Commissioning timelines are also improving, with pre-configured smart controllers cutting deployment time by up to 15%. Once systems are live, clients are generating an additional €25,757 annually per site through fully automated energy arbitrage, creating new revenue streams without adding operational burden.

Connect to Eight European TSOs with Fusebox

The reasons behind this shift go beyond operational savings. Risk mitigation has become critical. Real-time SoC (State of Charge) optimization prevents costly grid penalties, with some companies saving up to €300,000 per year. Thanks to Fusebox’s EMS platform, EPC clients can now tap into eight different TSOs across Europe and the flexibility markets they offer, creating multiple new revenue streams without additional operational burden.

Future-proofing is becoming a decisive factor too. As industrial customers tighten compliance requirements around ISO 50001 and sustainable energy management, embedded EMS capabilities are no longer a bonus, they are a requirement to stay competitive and win new contracts.

Many Nordic EPC leaders now view EMS as a key source of competitive advantage, not just a software add-on

For EPCs serious about leading the next era of energy infrastructure, integrating an advanced EMS is no longer just an upgrade, it is a survival strategy.

The post Why EMS is Non-Negotiable for Modern EPC Companies appeared first on Fusebox.

At Fusebox, we feel its presence every day, whether it’s helping streamline communications, acting as a powerful research tool, or assisting with code cleaning and product development. The capabilities of Large Language Models (LLMs) seem to stretch far and wide. But beyond the hype, is AI truly beneficial in the energy sector? Let’s dig a little deeper.

From Aging Energy Infrastructure to the Green Transition

To understand the challenge ahead, let’s take a quick look at Europe’s energy landscape. The good news is that our grid has remained highly reliable. You guessed it, there is a “but”. About 40% of Europe’s power distribution networks are over 40 years old, built for a centralized energy system where power flowed one way from coal and nuclear plants to consumers.

Today, the issue isn’t just rising energy demand but the decentralization of energy production. Distributed Energy Resources (DERs) like rooftop solar, batteries, and EV chargers inject power into the grid from countless points, making stability harder to maintain. Consumers feel the results through ever-increasing price volatility and negative electricity prices.

Grid congestion is another growing concern. Limited transmission capacity forces countries like Germany to curtail renewable energy, while aging distribution networks struggle to handle bidirectional power flows, causing voltage fluctuations, overloads, and inefficiencies.

For the green transition to work and for consumers not having to pay many times higher prices for it a solution is needed.

From No Data to Overload

Fifty years ago, before digitalization, grid operators had the opposite problem. They didn’t have enough real-time data. Power flows were mostly estimated, and monitoring was limited to a few key points. Today, the situation has flipped. With smart meters, distributed energy resources, and IoT sensors everywhere, utilities are now collecting more data than ever—far beyond what traditional grid management systems were built to handle.

To put it into perspective, by 2030, 250 million smart meters in Europe reporting every 30 minutes will generate around 4.4 trillion readings per year. Add to that millions of EV chargers updating power levels every few minutes and thousands of renewable plants streaming performance metrics, and the data challenge becomes clear. While the energy sector is generating vast amounts of information, it is still only a very small fraction of the 175 zettabytes of global data expected by 2025. The real challenge is not the sheer volume but making sense of it all in real-time.

More data should make grid management easier, but without advanced analytics and AI-driven aggregation, it is doing the opposite. Grid operators are stuck reacting to imbalances instead of preventing them. AI is no longer optional. It is the only way to transform this flood of data into actionable insights, making energy management smarter, faster, and more stable.

Do we need an AI

The challenge is no longer collecting data. It is processing and using it in real-time. The problem is that power utilities do not have direct access to real-time measurement data from the DSOs. Without it, they cannot accurately profile consumer consumption and production patterns or make AI-driven decisions that actually improve operations. AI thrives on high-quality, real-time data, but if utilities only have access to historical data, its potential is wasted.

This problem is becoming more expensive. The green transition relies on intermittent renewable resources, making it harder for utilities to balance supply and demand. A decade ago, imbalance costs for large Nordic power utilities were around three euros per megawatt. Three years ago, they had jumped to 25 euros per megawatt. Today, estimates put them as high as 60 euros per megawatt, showing just how much Balancing Responsible Parties are struggling with this issue.

How Fusebox Solves This Challenge

At Fusebox, we provide a way to bridge this gap. Our platform allows asset owners and power utilities to connect flexible assets directly to our cloud, giving them real-time, one-second interval readings from the asset. This is a two-way connection. We do not just collect data, we also send control signals back to the assets, allowing for instant optimization.

Our Machine Learning models analyze this real-time data, combining immediate measurements with historical patterns to optimize energy use. Unlike traditional systems that follow fixed rules, our AI continuously learns and adapts. It forecasts price shifts, consumption trends, and renewable generation to help utilities and asset owners reduce their imbalance costs and maximize the value of their flexibility.

AI in Energy: Hype or Real Help?

So, is AI really changing energy management? The answer is both yes and no.

On one hand, AI is undeniably a game-changer. It has the potential to predict imbalances before they happen, optimize battery storage, and automate decisions that used to take hours. It can make grid operations smarter, faster, and more cost-efficient.

On the other hand, AI is only as good as the data it works with. If power utilities do not have access to real-time data, AI can only analyze the past, which limits its ability to provide real value. Poor data leads to poor predictions. Implementing AI also requires investment, expertise, and a shift in traditional ways of working. While AI can automate decision-making, human oversight is still essential.

Ignoring AI is not an option, though. The energy system is becoming too complex for traditional approaches to keep up. Whether it is reducing price volatility, improving grid stability, or making renewable energy more efficient, AI is proving itself as a necessary tool. The key is not just using AI, but making sure it has the data it needs to deliver real impact.

What is a Flexibility Calculator, and Why Does It Matter?

Imagine you’re managing a large energy portfolio that includes solar farms, battery storage systems, and industrial consumers like cold storages, pumping stations, etc. Each of these assets behaves differently based on weather conditions, operational schedules, and maintenance requirements. Now what if you had a smart system that could predict how much energy flexibility (the ability to adjust energy consumption or production) each asset can offer at any given time? That’s exactly what our Flexibility Calculator does.

The Flexibility Calculator helps to predict how much energy flexibility each asset can provide, which is crucial for participating in energy markets where timing and precision can mean the difference between profit and penalties.

Smarter Energy Decisions with Our Flexibility Calculator

We’ve harnessed the power of Machine Learning (ML) to create forecasting models tailored to different types of energy assets. Think of machine learning as teaching a computer to learn from data, much like how an operator gains experience over time. The more data it gets, the smarter it becomes.

Our ML algorithms are trained daily on fresh data to ensure the most accurate forecasts. Every 30 minutes, the system updates its predictions based on real-time information, such as:

• Historical Cyclic Behavior and Impact of External Influences: How assets respond to repeating patterns and external factors over time.
• Asset States: The current operating condition of an asset (e.g., Is the solar panel generating at full capacity? Is the battery charging or discharging? Is the compressor running at partial load?).
• State of Charge (SoC): For batteries, this indicates the amount of stored energy available for use.
• User-Defined Regulation Conditions: Custom rules set by platform operators to control energy flow based on specific business requirements and constraints.

This dynamic adjustment means our platform doesn’t just make predictions, it adapts to changing conditions in real-time, helping operators make smarter decisions faster and reduce manual analysis workload.

Learning and Improving Over Time

When new assets are integrated, our system uses pre-existing models to start managing them immediately. For instance, if you add a new compressor to your portfolio, our Flexibility Calculator will initially apply general compressor behavior models. As the system gathers more operational data, the model becomes more accurate, evolving into an asset-specific predictor.

Similarly, for industrial compressors, the system quickly learns operational patterns such as load cycles, downtime schedules, and energy consumption behaviors, enabling precise flexibility forecasting over time.

This capability allows Fusebox to manage not only large-scale power plants but also a wide variety of small-scale assets, all under one virtual roof.

The result? Optimized participation in energy markets like mFRR (manual Frequency Restoration Reserve), aFRR (automatic Frequency Restoration Reserve), and FCR (Frequency Containment Reserve). These are markets where companies can help to balance the grid by adjusting energy supply or demand, and accuracy here is critical.

Why Choose Fusebox?

Our Flexibility Calculator isn’t just a fancy algorithm, it’s a dynamic system designed to maximize the value of your energy assets. It has been extensively proven in real-world portfolios with hundreds of diverse resources, including solar farms, battery storage systems, and demand response units. Every day, it demonstrates its value in some of the most dynamic energy markets.

Our Journey: From Demand Response to a Pan-European Presence

Fusebox’s journey began a decade ago in demand response, where we mastered the integration and management of a wide range of flexible devices, including pumps, compressors, HVAC systems, batteries, crushers, and floor heating. Over the years, we’ve standardized connections for nearly 100 different asset types, ensuring our solutions are safe, functional, and scalable. This expertise forms the backbone of our platform and drives its success in diverse markets.

As our founder and CEO, Tarvo Õng, explains:
“With our strong foundations in asset aggregation and management, it made perfect sense to build advanced software on top of that. Our Virtual Power Plant (VPP) takes asset management to the next level by centrally monitoring and controlling whole portfolios and trading them on ancillary markets. On a local scale, our Energy Management System (EMS) helps solve even more complex challenges, like managing Distributed Energy Resources. These tools allow us to go beyond demand response and tackle the modern energy problems our clients face every day.”

In just two years since launching our VPP software, Fusebox has expanded to 13 countries. Tarvo sums it up: “Our growth shows that we’re solving real problems. Clients trust us to help them access ancillary markets with solutions that fit their unique needs.”

Success Stories That Build Confidence

Fusebox’s solutions have delivered real results for clients across Europe and beyond. One of our newest clients in Mexico used our EMS to optimize solar panels and batteries. By automating charging during low-cost hours and using stored energy during peak demand, they reduced energy bills by 25% and gained energy independence.

In the Nordics, a utility struggling with a diverse asset portfolio turned to our VPP platform. It helped them streamline operations and access ancillary markets like mFRR and aFRR, significantly boosting their revenue. In Greece, another utility built a demand response portfolio with Fusebox, expanding services to small and medium businesses while supporting the country’s transition to renewable energy.

In Northern Europe, a client used our VPP to optimize energy use, improve grid stability, and reduce inefficiencies, leading to substantial savings for their customers. These examples highlight how Fusebox turns energy challenges into opportunities for growth.

What This Means for You

Fusebox’s presence in 13 markets isn’t just about growth—it’s a powerful advantage for our clients. By working in some of Europe’s most advanced flexibility markets, we’ve gained invaluable expertise that helps companies in developing markets prepare for opportunities before they even open.

When it comes to choosing an EMS or VPP solution, energy companies often face three options: building their own software, working with a local provider, or partnering with an international company like Fusebox. As Tarvo explains:
“Building your own software might seem appealing, but it requires immense time and resources. It’s taken us 10 years and over 6 million euros to get here. Local providers can offer localized support, but they often lack the experience to compete in advanced or diverse markets. We come from one of the most advanced markets, the Nordics, and that expertise is already built into our solutions.”

Some international providers impose rigid systems that force companies to overhaul operations. Fusebox takes a different approach. Our modular platform allows clients to choose only the solutions they need and integrates seamlessly with existing systems, enhancing them without disruption. Tarvo adds: “It’s about helping companies move forward without losing what already works.”

Whether you’re looking to optimize energy use, expand into ancillary markets, or future-proof your systems, Fusebox offers the expertise and flexibility to meet your needs.
