  • Intelligent power generation and control enables medium-sized companies to sustainably optimize their own electricity consumption - an important milestone in optimizing the energy balance
  • Capping peak loads reduces the complete energy costs
  • In addition, Digital Energy Solutions moves forward with island capability enabling energy self-sufficiency for their customer Spanner Re²


Munich, December 6, 2017 Digital Energy Solutions, a joint venture between the BMW Group and the Viessmann Group, has launched a pilot project to optimize total energy consumption at Spanner Re², the leading manufacturer of wood-based combined heat and power units sustainable power generation and storage. The pilot project is a groundbreaking example of how small and medium-sized enterprises can autonomously generate, store and use "green" energy.

The aim of Digital Energy Solutions and Spanner Re² is primarily to combine the provision of network services with the optimization of the total energy consumption of Spanner Re² and make it more sustainable. Digital Energy Solutions has been analyzing Spanner Re²'s internal energy consumption through real-time visualization since 2016.

In 2017, a system was put into operation to ensure sustainable self-generated electricity. It features a 62 kWp photovoltaic system and a Re² EnergyBlock - a turnkey wood-power system with 45 kWel. The system optimizes Spanner Re²’s own electricity consumption via a battery storage with 280 kW and integrated load peak capping.

The necessary control algorithms were jointly developed and implemented through cooperation with Viessmann as the project partner. All units are connected and controlled by the Energy Monitor developed by Digital Energy Solutions. The Energy Monitor is a software solution that companies use for transparency and monitoring of energy production and consumption. The overall system installed at Spanner Re² also ensures island capacity for time intervals and ensures the company's energy self-sufficiency. This island operation has already been successfully tested, so that the power supply can be maintained in case of power failure.

Ulrich Schmack, Managing Director of Digital Energy Solutions GmbH & Co. KG: "The project is a great success on the way to sustainable energy through the management of storage facilities. This is confirmed by the early approval by the network operator Bayernwerk - even before official recommendations for action were formulated and published by the Federal Association of the Energy and Water Industry (BDEW). We clearly see ourselves as pioneers in this area and want to fulfill this role in the future as well. Digital Energy Solutions manages entire systems in such a way that the customer achieves the optimum of revenues through network services and cost savings through self-consumption optimization. "

In 2018, Digital Energy Solutions will accelerate the integration of charging stations into intelligent load management and the integration of electromobility solutions into the overall project. This allows Digital Energy Solutions to take its customer Spanner Re² one step closer in the direction of sector coupling, the connection of electricity, heat and mobility in a complete electrical system.

Bernhard Seiler, Head of Overall Systems at Spanner Re² GmbH: "The project represents a decisive step towards more self-sufficiency in energy supply. Such concepts can significantly improve security of supply, especially in regions with a sensitive energy infrastructure, for example in rural areas where we significantly reduce the risk of undersupply.

energyblock canada

The Canadian community Kwadacha is not connected to the national grid. Until recently, the electricity was produced exclusively by diesel generators. With the EnergyBlock from Spanner Re² GmbH, electricity and heat production now occurs in a climate-friendly way. The new energy source is wood, which is grown by the local forest management.

Neufahrn i. NB. / Kwadacha. The compact, space-saving container-variation of the EnergyBlock from Re² provides flexibility and autonomy. Three Biomass CHP´s each with a performance of 45 kWel and 108 kWth are plugged into the complete turn-key solution. The EnergyBlock can be operated both “On-“ and “Off-Grid”, providing independently generated energy from an existing grid. “Fort Ware, in British Columbia, is as one of the furthermost distant aboriginal-settlements form the civilization in Canada known. There are very extreme weather conditions with a snow depth of up to three meters and temperatures of -40 degrees Celsius. Of course this was a hardness test for the team of Re² and for our constructions. After the first winter and a plant availability of over 80 percent it showed that our patented technique and our team can also handle challenges like this”, said Re² project leader Bernhard Seiler proudly. The EnergyBlock is run exclusively with dead wood from the local area. The electricity and heat produced by burning the deadwood, supplies many households, the local school, a community- and guesthouse as well as four green houses. The produce from the green houses eliminate the need for the 400 km journey that locals take to the distant city of Prince George for groceries. “Previously over 150,000 liters of Diesel had to be transported over a 1,000 km distance to fuel the community. It took 10 days, at temperatures of -30 to -40 degrees which was a huge undertaking. With our EnergyBlock the community can use their natural resources and also strengthen the economy”, said Re² director Thomas Bleul. “This Project is exemplary and we are pleased about our achievement of a new milestone in the direction of the future of energy with our proven Biomass technology”, said Bleul.
