Energy Storage
n the era of rapid development of renewable energy sources, energy storage systems (BESS – Battery Energy Storage Systems) play a key role in stabilizing and optimizing the power system. They not only allow for more efficient use of produced energy but also increase the profitability of the entire investment. Hekla Energy is a partner that combines advanced technology with extensive experience, offering comprehensive management of energy storage systems tailored to the individual needs of owners of large-scale storage installations.
Advanced Trading and Forecasting Infrastructure and the GridFlex NX System
- Electricity from renewable sources at your fingertips
Hekla Energy bases its services on a modern infrastructure that combines advanced forecasting tools with the GridFlex NX system — an innovative platform for managing energy storage systems. This ensures top-tier technological support, enabling you to maximize profits and minimize risks related to energy price fluctuations and market volatility.
Market Access — Buying and Selling Energy from Battery Energy Storage Systems (BESS)
The Market Access offering is designed for owners of energy storage systems — both standalone units and those integrated with renewable energy power plants, such as solar or wind farms. This service enables efficient buying and selling of electricity on the energy market, based on precisely developed storage operation schedules.
As part of the service, clients can either prepare the operation schedule for their storage system independently or entrust this task to our experts, who use advanced forecasting algorithms and market analysis. This approach ensures maximum revenue generation and optimal resource utilization.
Energy Storage Management — Price Arbitrage
One of the most effective operational models for energy storage systems is price arbitrage. Using a proprietary trading model, Hekla Energy develops daily storage operation schedules based on the Day-Ahead Market (FIXING I) auction. This strategy allows energy to be purchased when prices are at their lowest and sold when prices peak.
Our model achieves over 95% effectiveness in capturing price spreads. It takes into account the unique parameters of your storage system, such as power, capacity, number of charge cycles, and configuration (standalone or integrated with a renewable energy source). As a result, the schedules are precisely tailored to the specifics of your installation and current market conditions — ensuring revenue maximization.
Energy Flux NX — Intelligent, Automated Energy Storage Control
Energy Flux NX is an innovative technological solution developed in collaboration with our partner, Nomad Electric Services. It offers not only comprehensive commercial management, but also real-time physical control of your energy storage system.
The system automatically manages charging and discharging, executing predefined operation schedules without the need for manual intervention. Continuous monitoring enables dynamic adjustments to the storage parameters based on changing market and grid conditions — all while ensuring equipment safety and longevity.
With Energy Flux NX, your energy storage investment becomes completely hands-free, allowing you to focus on strategic business decisions while we handle the operational side.
Energy Storage in the Polish Power System
Energy storage systems are becoming an increasingly important component of the Polish electricity grid. With the growing share of renewable energy sources — many of which are inherently variable — storage enables effective grid stabilization, peak demand reduction, and greater flexibility in energy management.
Thanks to its experience and innovative solutions, Hekla Energy is a leader in the rapidly expanding energy storage management market. Previous implementations of solutions like SafePrice NX — which increase revenues from wind and solar power plants by over 10% — provide a solid foundation for the effective operation and optimization of energy storage systems as well.
Energy Storage Operating Models Aligned with Market Needs
Energy storage systems can operate under various models depending on business strategy and system configuration:
- Price Arbitrage — buying energy when prices are low and selling when prices are high within a defined time window (e.g., over a day).
- Capacity Market Participation — offering availability to deliver power during peak demand periods, generating additional revenue.
- Balancing Services — providing rapid responses to grid demand fluctuations and supporting power system stability.
Hekla Energy delivers comprehensive support across all these models, tailoring solutions to the unique characteristics of your investment.
Balancing Services — Support in Qualification and Management
For energy storage systems to effectively provide balancing services, they must undergo a qualification process and meet specific technical and regulatory requirements. Hekla Energy offers end-to-end support throughout this process, including:
- Preparation and verification of all required technical documentation
- Integration of control and monitoring systems
- Assistance with certification and registration procedures
- Ongoing operational support and expert consulting
Thanks to this, your energy storage system can actively participate in the balancing services market — increasing revenue while contributing to overall grid stability.

Frequently Asked Questions
What are energy storage systems and how do they work?
Energy storage systems are solutions that enable the storage of electricity — allowing surplus energy to be stored during periods of low demand and released during peak consumption. They help stabilize the grid and improve the efficiency and profitability of investments in renewable energy sources (RES).
How does Hekla Energy help manage energy storage systems?
We offer comprehensive trading services by acting as an energy seller and the Balance Responsible Party (PoB), generating price signals and operational schedules for the storage system. Additionally, we provide automation of storage system control, technical support, and certification assistance during the qualification process for providing services on the balancing capacity market. Our solutions enable maximizing investment revenues while minimizing risk.
What is price arbitrage in the context of energy storage systems?
Price arbitrage is a strategy that involves buying energy when prices are low, storing it, and then selling it when prices rise. This allows the energy storage system to generate revenue. Our trading model ensures effective exploitation of price differences in the market.
What are the main functions of an energy storage system in a modern energy grid?
The primary functions of an energy storage system include grid stabilization, supporting the integration of renewable energy sources, providing system services, and implementing price arbitrage strategies. This way, the energy storage system not only enhances energy security but also increases the overall profitability of the entire system.
How does Hekla Energy support the optimization of processes related to energy storage systems?
Hekla Energy provides dedicated products and tools that assist in the automation and optimization of energy storage system management. We offer market analyses, price forecasts, and dynamic operating schedules that enable investors to make informed decisions and maximize profits.
