“SMART GIRD” is a  set of  technology  implementation  that uses advanced sensing, metering, communication, control, computation  and  reporting  technologies  to  facilitate generation and distribution of  electricity more  effectively, economically and securely  to achieve desired balancing of supply and demand.

Today’s grid is aging and outmoded

Unreliability is costing consumers billions

Today’s grid is vulnerable to attack and natural disaster

An  extended  loss of  today’s grid  could be  catastrophic  to our security, economy and quality of life

Today’s grid does not address the 21st century power supply challenges

The benefits of a modernized grid are substantial

Responds  to  prevent  further damage.  Focus  is  on  protection of assets following  system faults.

Self‐heals

Automatically  detects  and  responds to actual and emerging  transmission and  distribution  problems.  Focus  is on  prevention. Minimizes  consumer impact.

Consumers  are  uninformed  and non‐participative with the power system.

How should India respond to Smart Grid Vision?How should India respond to Smart Grid Vision?

Following are basic preconditions:

• Commercially viable and self‐sufficient discoms

• Public awareness and acceptance of the smart grid from regulators

• A national smart grid vision and a flexible plan

• Appropriate smart grid standards, policies and regulations

• Build on R‐APDRP program and  link  it to  improvements  in service quality as defined by measurable KPI’s

• Identify  and  implement  smart  grid  concepts  that  will  reinforce  the operational efficiency of discoms

• Conduct  customer  and  market  surveys  to  develop  a  more  refined understanding  of  what  drives  customer  satisfaction,  and  analysis to develop a better understanding of demand and consumption

• Implement  techno‐commercial  ‘proof  of  concept’ pilot  projects  for initiatives  those have potentially high  impacts  and  can be  implemented independently .

Barriers in Smart Grid Implementation in IndiaBarriers in Smart Grid Implementation in India

Major hurdles are:

• No proven commercial viability for large‐scale smart grid roll out

• Poor financial health of most state‐owned T&D companies

• Low awareness of technological developments in the utility sector

• No coordinated national road map for smart grid deployment

• A fragmented industry

Regulators role on Smart Grid

The success of smart grid deployment depends quite a  lot on the regulatory landscape of the utility / country. The best and most efficient  smart grid products will not  reap  the benefits without  the  regulatory  framework  needed  to  make  these attractive to the customer.

For this purpose, a smart rate tariff should be there.

Page 27: 1000-1200 Smart Grid-The Indian Scenario - Schneider … · SAP-ISU WMS (SAP) AMI. SAP Modules ... • Low awareness of technological developments in the utility sector ... 1000-1200

In the Indian Context, any Capex intensive scheme is scrutinized by the Regulator on following criteria:‐

• Impact on Reliability

• Impact on AT&C Loss reduction

• Tariff Neutrality to the extent possible

While  in  developed  countries,  Smart  Grid  is  more  driven  by Reliability and Safety considerations ( including grid synchronization for  renewable  sources),  the  driver  in  India would  continue  to  be tariff neutral for some time.

Development of a Robust Business Case is extremely important forthe  effort  to  be  recognized  and  approved  by  the  regulators  as currently  India  is  in  a nascent  stage  for  implementation of  Smart Grids and there is a lack of proven technology and vendors.
