Stationary Storage: the missing piece in a
modern electricity supply system
1 http://www.bmu.de/themen/klima-energie/erneuerbare-energien/kurzinfo/
Electricification of islands and remote locations on
the rise by replacing fossil fuels as energy source
Abating consequences of climate change requires a
shift from fossil to low-carbon options
Increase of generation from renewable energy sources
worldwide. E.g. Germany aims at covering 80% of its
power consumption in 20501 with renewables
Economic growth spurs electricity demand and peak
load; thereby stresses the grid, while acceptance for
grid expansion is limited

A lot of challenges still ahead of us, but
progress is being made Suitable reimbursement models are currently only being explored
(“Neighborhood energy trading”)
Legislative frame conditions, regulations, permissions, etc. to be adjusted
to enable the benefits of storage to unfold as part of decentralized energy
supply system
Partnerships between utilities, grid operators, industry and all other
stakeholders is key
Pilot storage projects help to promote and foster the “Energiewende” as
well as prove the benefits
