Long-term financing of the project through a mix of hire-purchase and managed-services agreements enables Stadtwerk Haßfurt to make the investments. 
With its state-of-the-art microgrid technology and both SIESTORAGE lithium-ion battery storage units, Stadtwerk Haßfurt meets the strict requirements for participation in the primary control reserve market and taps new sources of revenue. 
The system also safeguards power supplies for the region’s critical infrastructure (waterworks).
