Washington DC October 2012 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.

Washington DC October 2012 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.
