What happened?
Background
In the weeks leading up to the failure, extreme heat had
caused power use to reach record levels in Northern
region including New Delhi.
Impact
• The July 2012 India blackouts included a power
outage that occurred on 30 July 2012 in northern
India, affecting 14 states.
• This outage affected over 300 million people
• This was followed by another power outage on 31 July
affecting 22 states.
• This outage affected over 700 million people

Findings of the
investigation committee
• Weak Inter-regional Corridors due to multiple
outages
• High Loading on 400 kV Bina-Gwalior-Agra link
due to overdrawal by some of the NR utilities,
utilizing Unscheduled Interchange (UI).
• Inadequate Response by SLDCs to RLDCs’
instructions to reduce overdrawl by the NR
utilities and underdrawal by the WR utilities.
• Loss of 400 kV Bina-Gwalior link caused the NR
system to separate from the WR.

How can this be
averted in future?
• Need for Ancillary services in India
– Current supply mix is focused on lowest average
cost and not the flexibility required to maintain grid
reliability
– Ancillary services can incentivize generation owners
to maintain appropriate reserves to respond to
system emergencies
– Right policies can provide incentives for investment
in fast response technologies such as energy
storage which can act as shock absorbers and
provide flexibility required to avoid such events.

Summary
• The problems faced by Indian grid operators on
30th and 31st July are not unique and exceptional
• 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 real
time monitoring systems, controls, energy storage
and Demand Response can provide the required
technical solutions for coping with similar
challenges in new future.
