Introduction
India’s GDP is growing at ~ 8% per year
Current installed generation capacity ~199 GW
Expected capacity additions over the next 5-10
years: 200 – 450 GW
Exponential increase in renewables, owing to
policies and economic incentives (Feed-in Tariffs,
RECs)
Critical need for bridging the supply – demand gap:
 Average power deficits: 8.3% ;
 Peak power deficits in industrial regions : 22% (MH), 17% (PB)

Implementing new Indian Grid Code 2012
Wind developers have to pay financial penalties
for deviations of more than ±30% of forecast
New wind energy generators will be able to fine
tune their schedules (based on forecasting) as
close as three hours before actual generation.
The operational frequency band has been further
tightened from ‘50.3 - 49.2 Hz’ to ‘50.2 - 49.5 Hz’.
This is generating interest in exploring better
forecasting and integrating storage for wind farms

Industrial Estates / SEZs
A Special Economic Zone (SEZ) is a geographical region to promote
commercial & industrial activity.
 Categorization of SEZ:
 Free Trade Zones (FTZ),
 Export processing zones (EPZ),
 Free Zones (FZ),
 Industrial Estates (IE),
 Free ports,
 Urban Enterprise Zones etc.
 It is anticipated that more than 300 new such townships with
more than 1M population will be developed in India during next
10-15 years.
 The green field development provides a great opportunity to
explore new business models for integrating energy storage
technologies to optimize the distribution systems and generation
mix for optimizing resources

Summary
 There is tremendous growth potential for supply &
demand growth in India including renewables
Current grid is not geared to tackle the potential
challenges that could impact PQ and reliability
New regulations as well as reliability and PQ concerns
are creating a need for evaluating of energy storage
Need to learn from international experiences and
successful energy storage project implementations
Need to create a clear business case and demonstrate
energy storage in various applications
