Value stacking is the art of combining multiple services in a Battery Energy Storage System (BESS) to unlock its full potential.
While it is commonly believed that BESS is primarily for reducing energy costs, the true potential is unlocked when the BESS actively participate in the electricity market to support the balance of your local or regional grid.
By combining cost-saving services – like peak shaving and PV self-consumption – with revenue-generating opportunities, such as selling battery capacity in electricity markets, you can significantly reduce your electricity bill and tap into new revenue streams.
Why Bess owners getting paid
Electricity system operators need to balance the system and reserve back-up capacity to ensure grid stability during peak demand or unforeseen disruptions. Batteries provide a fast and flexible energy reserve, which helps the grid balance supply and demand fluctuations when renewable sources underperform or demand spikes. This readiness allows grid operators to avoid costly power outages, avoid curtailment of renewable electricity and infrastructure expansion, making BESS a valuable asset they are willing to compensate for.
From savings to earnings
Investing in a BESS is more than just about storing energy – it is about unlocking the full potential of your investment. Value stacking ensures you get the best possible return by combining cost-saving measures with revenue-generating opportunities.
By combining features like peak shaving, arbitrage, PV self-consumption with trading in the electricity markets, your BESS doesn’t just lower your electricity bills – it actively works to generate income, turning your energy storage into a profitable asset.
What sets dynamic value stacking apart is its ability to adapt to market conditions and local energy needs, ensuring your system continuously delivers returns, even as the energy landscape evolves. Whether you’re selling excess energy in the market or supporting grid stability, your BESS is always working to maximize your profits. This dynamic approach means that your system isn’t just saving you money – it is also helping you earn more, offering a level of financial sustainability and long-term ROI.
At Pixii, we have gained extensive experience implementing value stacking strategies through real-world installations. With numerous systems successfully up and running, we have fine-tuned our approach to maximize the value of every BESS. Our deep understanding of energy markets and grid demands, combined and the collaboration with trusted EMS partners, allows us to customize each system, ensuring the highest return on investment for our customers.
Core components of value stacking
Cost-saving battery services
Peak shaving: Reduce energy use during peak hours and lower your electricity costs.
Arbitrage: Buy and store electricity when prices are low and use it when prices are high.
PV self-consumption: Maximize your use of solar energy by storing excess energy for later.
Backup power: Prevent costly downtime during outages to ensure business continuity.
Power boost: Handle short-term spikes in demand without overloading the grid, while expanding your business without expanding the grid.
Revenue-generating battery services
Wholesale electricity trading: Trade stored energy in bulk to balance supply and demand.
Frequency markets: Provide rapid-response energy to maintain grid frequency and stability.
Local flexibility markets: Provide energy storage and release services to manage local grid demands.
Voltage support: Help maintain stable voltage levels across the grid.
By combining all these services, your BESS becomes a powerful tool that not only saves you money but also creates new income opportunities.

Seamless Integration and future-proof flexibility
From the start, our BESS has been engineered to deliver the perfect value stack. It’s not just about hardware – it’s about a complete system that connects easily with energy sources like solar panels and the grid, managing energy inputs and outputs efficiently. The software at the heart of the system allows for real-time adjustments, making the system highly adaptable and future-proof.
With a modular design, the BESS can easily scale up to meet growing energy demands, ensuring that it continues to deliver maximum savings and revenue for years to come.
Support every step of the way
We make sure you are supported from installation to long-term success. With tight cooperation and seamless integration with partners, we wish to support you every step of the way so you get your system up and running smoothly. After-sales support is always available, and our online tools help you monitor your system in real time, ensuring you get the most out of your BESS.
And to help you navigate the energy market, we connect you with brokers who can include your system in Virtual Power Plants (VPPs), so you can focus on your business while earning additional revenue.
The bess way to upgrade your grid
Enabling a greener, decarbonized future
Beyond financial returns, value stacking plays a crucial role in supporting the transition to a more sustainable, decarbonized future. By integrating renewable energy sources, your BESS helps reduce reliance on fossil fuels and stabilizes the grid, even as renewable energy output fluctuates.
This shift is essential in enabling widespread adoption of clean energy technologies and reducing overall carbon emissions. In this way, investing in a BESS with value stacking isn’t just an investment in your bottom line – it’s an investment in a greener, more resilient future for all.
Your BESS becomes a key enabler of the green shift, contributing to the global push toward a sustainable, low-carbon energy landscape.
