Tradition meets modernity
The traditional Hilwartshausen monastery estate was founded back in 960 and has an eventful history behind it. But the independently operating biogas plant (BGA) also has a long tradition. Since 2011, investments have been made on site in the construction, operation and ongoing technical development. Over the years, three combined heat and power plants (CHP) with a combined output of 1.15 MW have been gradually installed. The gas storage facility with a volume of 3,386 m³ is also impressive.
The BGA itself is located less than 200 meters on foot from the farm buildings, close to the Weser. The main focus of substrate production is on cattle manure (9,100 tons) and dry chicken manure (2,900 tons). A small proportion of the power and heat produced is supplied to the monastery estate and is used to heat the buildings and dry grain.

How Klostergas GbR makes optimum use of the 4h-PRL time slots rule
From direct marketing to balancing power
The company has been working closely with e2m since 2012. Entry into the balancing power markets began via direct marketing. The CHPs were initially prequalified for the secondary and minute reserve with the responsible transmission system operator TenneT. Thanks to consistent flexibilization, the provision of the demanding PRL has also been possible for some time now. Previously, the three motors with 250 kW, 265 kW and 500 kW were operated by the operator Lars Grünewald with an independently developed schedule. This service is now increasingly being provided by e2m.
Individual timetable creation pays off
This is because the daily balancing power auction for PRL, which was introduced on July 1, 2020 and which – like the existing time slots for SRL and MRL – saw a switch to 4h time slots, has further increased the effort required to create individual schedules. At the same time, however, the new provision time slices also offer new opportunities for systems that are already flexible. This plays into the hands of Klostergas GbR’s intention to operate as efficiently as possible.
Revenue doubling through timetable optimization
The result is an economically optimized use of the engines. Lars Grünewald comes from a respected, traditional farming family in the region and is delighted with the proven success: “The advice from e2m with the optimized schedule convinced me. The system now generates almost double the revenue and we can adjust production much better thanks to the manageable 4-hour time window.”
