ECO STOR GmbH Tackles Grid Congestion with Innovative Forecasting and Market Optimization in Bollingstedt Battery Project

ECO STOR GmbH is a company specializing in large-scale energy storage solutions, aiming to enhance grid serviceability. With around 70 experts across various fields such as system engineering and battery technology, they manage the entire value chain from development to operation. One of their notable projects is located in Bollingstedt, featuring over 100 MWh capacity with connections involving numerous battery containers and substations. This project began construction in April last year and started operations recently. The regional grid's heavy reliance on wind and PV feed-in presents challenges like congestion during simultaneous high renewable production periods. To address this, ECO STOR developed an advanced forecasting tool using historical data for predicting grid utilization based on nearby renewable forecasts. By optimizing discharge schedules two days ahead of market auctions, they've significantly reduced curtailment hours from an estimated 80 annually to just half an hour. Their strategy involves aligning dispatch behavior with market price signals while maintaining financial viability despite potential revenue reductions due to operational constraints aimed at preventing strain on the grid infrastructure.

Energy storage is usually not an end in itself. The technical and financial benefits are always the main concern. However, it is often difficult to prove the profitability of use cases. Acquisition or operating costs are often still too high in relation to returns. But the market is changing, and new framework conditions and regulations are creating opportunities for new use cases. The most attended session of the ees Europe Conference 2024 already gave attendees an overview. In 2025, we will take this format to the next level. In this session, you will learn more about the latest challenges and how to overcome them to create financially profitable use cases.
