GENESIS

• The current energy path is unsustainable. • Future patterns of global energy consumption and

production – Need at least 50% more energy in 2030 than it uses

today

• Carbon emissions are set to follow a similar track.

SMART GRID - DRIVERS

4

The key market drivers behind Smart Grid solutions

1) Need for more energy. 2) Sustainability. 3) Security of supply. 4) Need to embrace renewable energy resources. 5) Ageing infrastructure.

Installed capacity = 1,64,836 MW

Per capita usage = 612 kwh Energy short fall = 10.6% Demand short fall = 12.1% [As of September 2010]


Drivers for India

5

Six factors

1. Supply shortfalls - Demand continues to outpace supply.

2. Loss reduction – AT & C loss about 25-30%,.

3. Human element - AMR would lower recording and other errors

4. Peak load management - Direct control or Pricing incentives.

5. Renewable energy – 20,000 MW of solar energy by 2020

6. Technological leapfrogging – Bring in latest technology

Smart Grid - definition

7

• A “smart grid” is a digital, self-healing energy system that delivers electricity from generation sources, including distributed renewable, to points of consumption.

• It is capable of optimizing power delivery and facilitating two-way flow of power and information across the grid, enabling end-user energy management.


Smart Grid - characteristics

8

The important characteristics of smart grid are

1. Self-Healing and Adaptive – Rapidly detects re-configures and restores power supply.

2. Interactive with consumers and markets - Motivates and includes the consumer and stakeholders.

3. Best use of resources and equipment - Optimizes assets and operates efficiently.

4. Predictive rather than reactive – the system operation can be planned to avoid emergencies.

5. Accommodates all generation and storage options.

6. Two-way communication across the grid - Enabling end-user energy management.

Need for pilots

10

Smart grid pilots are essential

Operate in lowered risk environment Field-test technologies

Develop understanding

Business model implications

Regulatory aspects

Mainstream roll out.


OPPORTUNITIES AND CHALLENGES

11

The industry has taken a significant step forward towrdas

technology & opportunities to extract more insight and

value.

key challenges of today’s smart grid pilots:

• Lack of regulatory measures.

• difficulty to align and allocate risk and reward

• Data privacy, cyber security, interoperability and standards

• Technologies and pricing structures - make it difficult to

understand cause and effect.

• Consumer engagement challenges

• Metering pilots could not convince the regulator and the

consumer over the true benefit.

Lessons Learned

12

Political and Regulatory Context

Right regulatory and policy framework

Drive for global standards

Scoping Phase

Clarity and ambition in design

Grid vs Consumer pilots

Successful commercial collaboration

Experiment with new operating and business models

Develop consumer insight

Segment consumers by behavior

Target business customers

Execution

Engage and educate consumers

Re-engineer in the field

Share lessons from the field

Generation pilots

13

Generation pilots - To integrate all forms of Renewable Energy (RE) with grid especially at LT level.

Benefits - Validation of technologically feasible energy

sources. Study of grid connectivity challenges.

Standardisation of Grid connectivity. Business case for small roof top RE systems,

Micro grids formulation and study.


Transmission pilots

14

Transmission pilots can be planned with the objective of studying WAMS of Transmission Network

Benefits - Dynamic insight into Power System


Distribution pilots

15

Distribution pilots - Aim of Transforming power distribution process in to an information based procedure involving monitoring and control of MV and LV networks. Benefits - Structured network

Standardised automation, MV and LV network control AMI Asset management Outage minimisation Peak management Volt / Var control, Load Balancing


Utilisation pilots

16

Utilisation pilots - objective of addressing End use energy efficiency Demand Side Management Customer premises control.

Benefits - TOU options DSM / DR programs Smart buildings / homes Smart appliances control Optimum energy utilisation Plug in Electric Vehicle


AN APPROACH

17

Smart grid philosophy - centers on removing or

minimizing supply – demand gap

For instance

In the chosen project area

restrictions if any are relaxed

existing demand will go up.

Option 1 – Put RE for the increase

Option 2 - Moderate demand

Option 3 - Switch of non priority loads.

Option 4 - Introduce TOU tariff structure to study

load leveling

CONCLUSION

• Pilot study is a requirement.

• Focused pilots with converging objectives

• Business case for each scenario

• Evolving Regulatory frame work
