Summary
 With increasing Wind and Solar penetration, states are finding it difficult to handle the Grid operation.
 For stability and success with large percentage of renewable penetration in the Grid, addressing all of
technology, policy and financial measures is needed.
 From technology perspective
 Bottom-up data analysis approach in identifying the optimized storage requirement at Low voltage
Distribution level to Transmission level.
 Balance of investment between strengthening of transmission network and installing balancing systems like
energy storage systems.
 From policy perspective
 Better clarity on legality and regulations on ESS usage
 Matrix definition for evaluation of performance of ESS in Grid usage.
 From financial measures perspective
 Stricter penalization with respect to grid violations and stabilization
 National level funds/grants/subsidy set up to promote storage systems.

Drivers
Drivers for Renewable Energy & Challenges in Grid Integration
Energy System Decarbonization
− Stabilizing climate impact from fossil fuel use
− CO2 emissions related to energy use account for 70 % of total GHG emissions
Long-term Energy
Security
− Average energy costs tend to decline over time for renewable generation
− Insulation from fluctuations in fossil fuel prices because of geopolitical disruptions
− Better geographical distribution and non-diminishing nature of Renewable resources
Expansion of Energy
access to new consumers
− Meeting the energy demand of a growing population
− Meeting demand for new uses and industrialization
In addition to the current challenges faced by Grid due to load variability, renewable integration leads to
Challenges
Uncontrollable variability
23
•
•
Non Constant Output even if we could predict
Fluctuations in frequency and voltage.
•
Partial unpredictability
Inability to predict exact weather wind/sun inspite of advanced
weather prediction systems

Actions Taken
Impact
Relevance for India
United
States
• United States has recognized quality of ancillary services
provided via following FERC1 orders:
– Order 755: Higher tariff for fast responding services
– Order 784: Recognized storage devices as third party
services & allowed tariff recovery for utilities
– Order 792: Included storage interconnection as part of
small generation units, esp. solar plants
• In 2011-2014, ten states developed their own roadmaps
and bills to support energy storage
• These regulations and bills have helped in
– Offering services with emphasis on speed and
accuracy of response
– Competing in the market with traditional
ancillary options such as gas and pumped
hydro
– Allowing utilities to recover cost of these
services from the end-consumer tariffs
• India will need to establish ancillary services
market before these interventions can come in
• In the US, battery storage systems are
competing against gas peakers for speed &
accuracy, while India still relies on coal
generation which are much cheaper and slower
• Regulatory changes will have to be made at
state-level in India as well, with many changes
governed by Forum of Regulators
Japan
• Grid inter-connection code for storage devices (JEAC
9701) created in 2012
• Inclusion of batteries in Electricity Business Act, Fire
Service Act, Fire Prevention Ordinance and Building
Standards Act
• METI developed stringent guidelines to govern
renewable energy quality
• Renewable energy integration allowed via
small and distributed storage systems,
• Faster regulatory approvals up to 80MWh
• Batteries deployed for renewable integration
• Creation of installation regulations can
simplify approval route in India
• Renewable integration quality in India should
be made stringent
Italy
• Batteries were used to integrate renewable
generation in South Italy with national grid
Germany
• Battery storage recognized alongside gas and
pumped hydro, however no incentive for fast
response systems
• In India, grid operators and LDCs may be
allowed install batteries to help with energy
balancing and frequency regulation
Europe
Italy
• In 2011, grid operator was allowed to “develop &
manage electricity storage systems using batteries”
• In 2014, network access rules for energy storage were
defined
Germany
• Included formal definitions of energy storage in the
Federal Energy Industry Act
Tamil Nadu – Renewable Penetration
• Renewables account for over 45% of Tamil Nadu’s total generation capacity (>80% by wind – 7.6GW)
• Such high % of renewable penetration create challenge for Grid management.
Tamil Nadu Power Generation Profile
26
Tamil Nadu – Wind Variability and Loss of Generation
• Wind power generation in Tamil Nadu can be seen to vary between 50MW to 3000MW on some days.
• According to a CAG report, in Tamil Nadu wind power backed down was 6,018 million units (MUs) during 2007-2014.
• Resulting in a loss of revenue to the extent of INR 2,040 crore.
Loss of Wind Generation in Tamil Nadu 2012-2013

Hybrid power system : Addresses Challenges PARTIALLY
Uniqueness of Hybrid system
 Leveraging various technology for best performance.
 Various generation sources complement each other
while mitigating each other’s drawbacks.
Key drivers for hybrid system
 India is blessed with ample solar and wind resources.
 Wind power has a generation potential of
3,00,000MW at 100m height.
 Total solar target at 1,00,000MW by 2022.
 Large geographical area having higher solar and wind
energy potential.
Owing to large potential and target, more wind and solar
projects to come up in future
28
Energy Storage with Renewable Integration
• Considering a case of Solar-Wind hybrid generation in integration with Energy Storage for serving a constant
load.
Power (kW/MW)
• Inherent variability of Wind & PV generation can be firmed up and balanced with Energy Storage system.
