Transmission Upgrades – Green Corridors• Green Corridors planned forTamil

Nadu, Gujarat, Rajasthan, Karnataka, Andhra Pradesh, Maharashtra, Himachal Pradesh and Jammu & Kashmir.

• The transmission system costing about Rs. 32,000 crores (5 billion US $) have been planned to cater to the needs of about 32 GW RE capacity addition program for the 12th Plan (2012-17).

• INR 2000 Cr. (~$333 Million) investment anticipated for energy storage investments.

• Currently looking for 1-5 MW pilot demonstration projects for technology validation

Implementing new Indian Grid Code• Wind / Solar developers may have to pay financial penalties

for deviations of more than ±30% of forecast• 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 Hz to 49.2 Hz’ to ‘50.2 to 49.5 Hz’.

• This is generating interest in exploring better forecasting as well as integrating storage for wind farms

• This provision is currently put on hold as policy makers are exploring alternative options

India Opportunities

India Opportunities• India plans to integrate 50GW renewables (30 GW wind and 20 GW Solar)

between 2014-2020.• Proposed ancillary service introduction by CERC could create a 3-4 GW

opportunity for frequency regulation by 2018• 600,000 telecom towers – 70% + utilize DG for backup / primary source have

been mandated by regulators to reduce diesel consumption• Over 100,000 Bank ATMs that need backup solutions• India Plans to Install 26 Million Solar-powered Water Pumps (over 9 Million

diesel powered water pumps in operation)• Over 300 million people currently do not have access to grid electricity and

India’s National Mission for energy access aims to provide at least 8 hours of access by 2017

• India’s National Electric Mobility Mission aims to get 6 million EV / HEVs (including 2 wheelers) on road by 2020

• Indian railways is 5th largest rail network with over 65,000 km of rail network and is driving integration of energy storage for public transportation systems22

India Energy Storage Alliance India Energy Storage Alliance was launched in

2012 to help technology and system integration companies involved in energy storage and microgrids to understand and capture opportunities in thro growing market

In 2013 launched IESA-Knowledge Partner Network with a goal of addressing energy storage applications in over 10 key sectors of Indian economy

1. Working with key stake holders and policy makers for developing national and state level policies related to energy storage applications for energy access, renewable integration, diesel replacement, ancillary services and electric transportation. Collaborations with other trade groups such as INWEA and WTMA MERC Smart Grid Co-ordination Committee CEA – ISGF smart grid regional workshops for utilities and regulators MNRE – Energy Storage Standing Committee International collaboration through GESA initiatives and IRENA workshop

2. Developing a detailed reports & white papers Introduction of ancillary services in India and role of energy storage

technologies in improving grid reliability and power quality Series of market reports developed on energy storage potential for wind,

solar and telecom sector.

IESA Road Map 2014

3. Undertaking research on mapping various storage technologies with high potential applications in India such as renewable integration and diesel replacement.

4. Focusing on building international partnerships by bringing special IESA delegations and hosting IESA Pavilions to showcase member companies at key global events such as Energy Storage Europe – Dusseldorf, Germany (March 2014) ESA Annual Meeting - Washington DC, USA (June 2014) Energy Storage China (June 2014) Energy Storage North America (Sept 2014) Energy Storage Summit – Japan (November 2014) Energy Storage India – New Delhi (Dec 3-5, 2014)

5. IESA-ETN: Emerging Tech News Quarterly magazine Inaugural Earth Day issue Launched on Earth Day 2nd issue to be launched at ESA Annual conference, June

Summary

India presents large opportunities for renewable energy integration as well as energy storage & microgrid technologies

We need fundamental policy reforms as well as better implementation mechanisms for existing policies to avoid recurrence of such event in future

Emerging technologies including advanced controls, energy storage and Demand Response can provide the required technical solutions for coping with similar challenges in new future.

Need industry to come together to address policy barriers and educate potential customers for enabling fast adoption of these technologies.

Need industry to get involved with IESA to achieve this change.
