How can battery storage enhance the return on your investment? In recent years, Poland’s renewable energy (RES) sector has undergone major changes that have significantly affected how energy fed into the grid by wind farms and solar installations is settled. The transition from monthly to hourly – and eventually 15-minute – settlement intervals is intended to better reflect actual market prices. However, it also poses new challenges for energy producers. If you are looking for solutions to help restore the profitability of your RES investment, this article is for you. We will explore the benefits of implementing industrial-scale energy storage systems. magazynów energii.
The Evolution of Energy Settlement Mechanisms
Until mid-2024, owners of wind and solar farms sold energy to the grid based on average monthly market prices (RCEm). However, starting from 1 July 2024, hourly market prices (RCE) have been introduced, meaning compensation for the injected energy now depends on real-time hourly price fluctuations. In mid-2025, this interval is expected to be shortened further to 15-minute periods, making energy producers’ revenues even more sensitive to short-term price volatility.
Selling Energy at Unfavourable Rates
If you operate a renewable energy farm, these changes mean you must align your energy production more precisely with dynamically fluctuating market prices. Without the ability to store energy any surplus generated during periods of low demand must be sold at lower prices, reducing the profitability of your investment. Additionally, during times of energy oversupply, grid operators may remotely curtail or shut down the operation of wind and solar farms to balance supply and demand. This can lead to further financial losses for you as the operator.
Energy Storage as a Strategic Solution
In the context of these challenges, integrating energy storage systems with wind and solar farms is becoming a key component of energy production and distribution management strategies. Energy storage systems allow surplus energy to be stored during periods of low demand and used or sold when market prices are higher. This approach not only improves the return on your investment but also supports grid stability by reducing the risk of overloads and outages.
Flexibility Through Modular Design
We understand that energy needs can evolve over time. That is why Sermatec energy storage systems feature a modular design that allows for gradual expansion. As your renewable energy installation grows, you can easily increase storage capacity without replacing the entire system. This flexible solution minimizes upfront costs while giving you full control over stored energy. With smart energy management, you can optimize usage and improve the reliability of your infrastructure.
