Insights from the india blackouts opportunities for energy storage, dr and microgrids

  1. 1. 03-10-2012 1 Washington DC October 2012 Insights from the India Blackouts: Opportunities for energy storage, DR and microgrids Dr. Rahul Walawalkar CEM CDSM Vice President, Emerging Tech & Markets Executive Director, India Energy Storage Alliance Customized Energy Solutions 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 Source: Wikipedia
  2. 2. 03-10-2012 2 Washington DC October 2012 Northern Grid fails at 2:30 AM in 7 states Grid Frequency data 30th July Washington DC October 2012 Northern & Eastern Grid fails at 1:05 PM North Eastern Grid fails later in the afternoon. Grid Frequency data 31st July
  3. 3. 03-10-2012 3 Washington DC October 2012 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.

  4. 4. 03-10-2012 4 Washington DC October 2012 Existing vs projected Capacity Additions 7 Washington DC October 2012 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.
