Brief portraitEnBW Energie Baden-Württemberg AG
› Third-largest energy company in Germany
›Business segments: electricity generation and trading, electricity grid and sales, gas, energy and environmental services
› New transport grid: 300 €/kW (dena II, distance 1000 km) Competitive costs for long-term storage are the biggest challenge!
Example pumped hydro storage plant
›Planned project by EnBW
›New upper and lower station with enlargement of existing lower water in Forbach as underground cavern storage

Example Pump Storage Plant
›Possible construction model Seekopf
›Cycle energy efficiency 70-80%, ca. 9 h

The energy market will fundamentally change in the future
› energy consumption regulates generation
› regulation with a few big units
Yesterday Tomorrow
› (renewable) generation regulates consumption
› regulation with many power plants/storages
› activating of flexibility in energy consumption

MeRegio-concept
› All energy services (both technically and commercially)
› Trading platform for energy products, system services and value-added services
› Increase energy efficiency and more local renewables by direct interaction of energy users and local generators via trading platform
Project Minimum Emission Regions (MeRegio)1000 test installations in Baden-Württemberg

Course of action intelligent grid preliminary conclusion
›Variable energy tariffs influence energy use by private customers, even in case of manual regulation by clients
›Up to now maximum load influence at least 10 % during total time period
›With an average load of about 500 W per household and with 1,000 clients about 50 kW controllable load influencing for grid or energy logistic goals could be gainable
›Extrapolated to all households in Germany this leads to a magnitude, which comprises 50 % of the regulation market today

› Products/Tariffs› New tariffs for private recharging
› Load levelling products to stabilize the grid
› New products for operation in isolated network
› Technical Options
› Public charging infrastructure
› Battery products
› Battery exchange systems
› H2
Commercial Options
› Operator
› Financial investor
› Car-Sharing etc.
Smart grids and technologies result in new products

Alternative concepts: H2 - Power2Gas
› In the gas grid there is plenty of storage available („100 days storage“):
