Stabl Expert-Talk: How to use free grid capacities through battery storage

BET Consulting GmbH (BET) and Energy2market GmbH (e2m) present the BESS Co-Location Index, a new, freely accessible market index that transparently quantifies the daily added value that battery storage systems can achieve when operated together with photovoltaic systems. BESS co-location – the combination of PV system and battery storage at one location – is considered to be one of the most important trends for 2026 and 2027.

On November 21, Martin Dotzauer, Product Manager Biogas at e2m and independent consultant, presented his findings during a workshop at the Bioenergy Status Conference once again presented the results of the study published in April entitled “The Value of Flexible Bioenergy“, this time supplemented by initial updated estimates for the year 2024.

In PV Magazine, Christof Petrick shows how the combination of PV systems with green energy storage systems can open up new revenue potential and why flexibility is becoming a decisive competitive factor.

As Product Manager Biogas at Energy2market designed Martin Dotzauer since 2023 actively involved in the marketing and further development of biogas plants. He has been involved in the economic and regulatory framework conditions of bioenergy for many years. This summer he after fourand a half years successfully completed his part-time doctorate at the University of Leipzig – with with ae topic that fits in perfectly with his daily work.

The energy transition poses enormous challenges for plant operators: volatile energy markets, increasing regulatory requirements and the complexity of hybrid structures consisting of electricity, heat and storage. Heat-led plants in particular are caught between security of supply and economic efficiency. Only those who intelligently combine technical optimization and access to all relevant energy markets will be successful.

The Federal Network Agency (BNetzA ) opened the tender for biomass plants on August 27, 2025. Now that approval has finally been granted by the EU Commission, this will be carried out in accordance with the rules of the Biomass Package 2025.
