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
