A new microgrid at the Siemens corporate headquarters in Vienna, Austria, was officially completed in November 2020, with plans to provide balancing services to Austria''s electricity transmission system operator.
Under construction since 2019, the Siemens campus microgrid includes 312 kW at peak capacity of solar photovoltaic (PV) panels, 500 kW/500 kWh battery storage and Siemens eMobility charging stations. A Siemens Desigo building management system is also in place to adjust heating supplies during peak load periods, and a Siemens microgrid controller sits at the heart of the microgrid.
"A smart microgrid controller centrally orchestrates the connected assets and optimizes the power supply to take account of peak loads and grid capacity utilization," said Werner Brandauer, head of business development, Siemens Smart Infrastructure Digital Grid, in a recent Siemens story.
In a future phase of the project, Siemens plans to use the microgrid to provide flexibility services via an aggregator, which will help the grid to maintain a stable frequency. This will also generate additional income for Siemens Real Estate, the internal customer of the microgrid.
The battery storage system will play a role in the balancing market, but another potential source of flexibility is the electric heating used by the site''s kitchen. This kicks in only on cold days when the site''s district heating supply cannot meet the high demands.
"Desigo, which controls the electric heater, tells the microgrid controller that there is a new flexibility and the microgrid controller integrates it into its optimization algorithm for peak shaving," Robert Tesch, head of Digital Grid and Distribution Systems, Siemens Austria and Central and Eastern Europe, told Microgrid Knowledge.
Because of its unique combination of microgrid components and a connection to the infrastructure of an existing industrial firm, Siemens views this site as an opportunity to carry out innovative research.
The use of smart components and Siemens'' smart charging to control load is already demonstrating the use of microgrids to integrate e-mobility without expanding the local grid. According to Tesch, Siemens'' employees who charge their electric vehicles on-site are happy with the system.
Siemens, in collaboration with Nokia and A1, also plans to use a dedicated frequency range for microgrid communications. This should allow data exchange between the controllers and the tags, or charging points, to occur with a guaranteed data rate and short delays.
"We''re showing how microgrids will leverage the benefits of 5G technology in the future and how they can be implemented with minimum overhead wiring and short transmission times," Brandauer said in the Siemens story.

Enerox GmbH and G&W Electric have signed a strategic partnership to offer resilience and cost savings to the rapidly expanding microgrid market in North America
Wiener Neudorf, Austria, Bolingbrook, Illinois, July 14, 2022 – Enerox GmbH, better known as ''CellCube'', and G&W Electric, a US headquartered power grid solutions provider, have signed a partnership agreement to offer a new and integrated microgrid solution to the US-market. G&W Electric adds CellCube''s Vanadium Redox Flow Battery (VRFBs) as a key technology to their microgrid solution portfolio and becomes a ''Value Added Reseller'' for CellCube''s energy storage systems.
The partnership was initiated through G&W Electric''s construction of its own state of the art microgrid located in Bolingbrook, Illinois, U.S. with solar coupled to CellCube''s latest battery technology. CellCube''s Release 4 VRFB will provide more reliable and resilient power during seasonal peak demands, power quality issues and potential outages.
"After having recently established a 100% wholly owned subsidiary in Denver, Colorado, CellCube''s next preeminent project in North America is being realized", says Alexander Schoenfeldt, CEO of CellCube Austria and USA. "We are extremely pleased to cooperate with G&W Electric after having won them not only as a customer but also getting engaged in the fast-growing microgrid business. There is no better way to start a partnership and go-to-market than through such a large-scale real-life project."
"We see the microgrid market is entering a new stage where energy applications that allow for storing electricity from renewables over longer periods of time is gaining more importance", points out John Mueller, chairman and owner of G&W Electric. "CellCube''s long duration battery technology unlocks huge value for G&W Electric with the lowest total lifecycle cost of any technology in the market. For us, it is an obvious step to partner with the market leader of Long-Duration Energy Storage."
