Bavaria Automotive Tier-1 Microgrid & Dynamic EMS
High-density rooftop & EV-carport solar coupled with 48 MWh liquid-cooled BESS, sub-6ms robotic press protection, and automated EPEX SPOT DE negative-price charging.
Supplying aluminum structural castings for German electric vehicles requires huge induction melting power and zero voltage sags on robotic assembly lines. EnerX deployed 24 MWp of N-Type solar across factory roofs and 1,400 employee EV carports, integrated with a 48 MWh LFP battery bank. The EnerX AI EMS automatically charges the BESS during German negative-price wind/solar surges on EPEX SPOT and shaves peak industrial grid charges (Netzentgelte) by 46%.
Before & After EnerX Deployment
Audited operational and financial comparison before and after engineering integration.
High German industrial grid tariffs (€245/MWh all-in), punitive furnace peak charges, and Scope-2 carbon pressure from OEMs.
24 MWp PV + 48 MWh BESS + EPEX AI EMS slashes blended power cost to €92/MWh and protects 280 robots with 5.8 ms UPS.
System Architecture & Engineering Topology
Integrated multi-node busbar connecting generation, storage, control, and circular recovery.
Turnkey EPC & Engineering Scope of Work
- 1Turnkey EPC installation of 16.5 MWp industrial rooftop PV and 7.5 MWp steel solar carports with 350 EV chargers
- 2Integration of 48 MWh LFP battery storage with 20 kV medium-voltage static transfer switchgear (5.8 ms response)
- 3Deployment of EnerX AI EMS linked via API to EPEX SPOT DE/LU 15-minute intraday electricity trading
- 4Compliance engineering for German VDE-AR-N 4110/4120 grid codes and §19 StromNEV peak-shaving certification

7.5 MWp Bifacial Solar Carport Over 1,400 Employee EVs
Charges employee and fleet EVs directly from midday solar surplus while shielding vehicles from Bavarian winter snow.
48 MWh Liquid-Cooled LFP Bank & 20 kV Switchgear
Absorbs 12 MW induction furnace load spikes without transferring flicker to the Bavarian regional grid.
EPEX SPOT 15-Minute Automated Arbitrage Cockpit
Automatically charges the 48 MWh battery when German wind/solar surpluses push spot prices below €0/MWh.
Verified Results & Measurable Impact
Audited operational KPIs recorded after commissioning.
Reduction in German Industrial Grid Fees (Netzentgelte)
Achieved via precision peak shaving inside high-load windows under §19 StromNEV.
Annual Energy Cost Savings & Spot Arbitrage Gain
Combines 26.8 GWh of self-consumed solar power with 15-minute intraday battery trading.
Verified Scope-2 Carbon Reduction for OEM Audits
Secures long-term Tier-1 supplier contracts with BMW and Audi green-procurement standards.
“EnerX engineered a microgrid that meets German automotive precision standards: we cut our Netzentgelte grid fees by 46%, get paid to charge our 48 MWh battery during negative spot-price hours, and have 5.8 ms UPS protection on every casting press.”
