Increase of volatile power production leads to challenges in balancing production and consumption
Large-scale renewable
Challenge: Balancing production & consumption power
Decentralized generation Consumers turn to producers Photovoltaic Mixture between self-supply and feed-in
Volatile production Wind power plants Large scale solar power plants
Solutions Flexible generation technology
Grid extension
(e.g. gas turbines/ peaker, stand by, shut-down renewable)
(e.g. demand side management, smart grid)

Fluctuating energy production leads to different challenges for customers which could be solved by storage
Generator Renewable
Fossil
Transmission System Operator
Distribution System Operator
Prosumer
Different use-cases and technologies for storage Current roadblocks for breakthrough of storage
1) Technical maturity 3) Incentive schemes and regulations (e.g. fixed feed in tariff for renewable) 4) Viable alternatives available: (e.g. Fossil GT ramp-up within 30 minutes) Prosumer – blend of “producer” and “consumer”
