Overview of Lighting Energy in India
India – Facts:  Year 1947 Power Generation was 1362 MW  Year 2004 Power generation – 100,000 MW  Electrification of > 500,000 Villages  Year 2001 – 44% households without Electricity  Present Per Capita Consumption – 350 wh  Supply vs. Peak Demand Gap – 39,816 million Units (Peak Demand Gap = 17%)

Demand Side Management
  

 

Lighting Consumes 18% of Power in India as against 8 – 10% in Developed countries 13% of the peak load in Indian power system occurs for 365 hours a year – i.e. one hour per day at dusk In 44% households without Electricity, people still use kerosene lanterns which affect their lungs and eyes, besides generating high soot and pollution Energy backlog has concerned the government Unable to meet Demand / Supply Gap

Short term Solution
• The most effective and practical solutions to achieve immediate relief and reduction in the peak load demand is to
replace :  GLS by CFL

 

40W Fluorescent tube light by 36W (or 28W) FTL Electromagnetic ballasts by Electronic ballasts

“ A WATT SAVED IS 2.5 WATTS GENERATED”.
5 ELCOMA

Why CFL ?
CFL lamps can easily replace GLS lamps and offer the following benefits :     Relatively small investment per point (Rs.100 - 150) Easy to install retrofit solution High luminous efficacy Saves 80% on electrical energy for same light output when compared to GLS lamps   Have longer life (6 – 12 times longer than GLS) Wide range of shapes, sizes and colours for varied applications 

Environment friendly.

Cost Benefit Analysis
Cost Benefit Analysis for using Retrofit CFL Savings in Electronic Retrofit CFL over a lifetime of 6000 burning hours
1 2 3 Electronic Retrofit CFL Replaces GLS Savings in Electricity consumption over 6000 hours (2-1) x 6000 1000 4 5 6 7 Savings in electricity bills per lamp @Rs.3.50 per KWH Cost of Electronic Retrofit CFL Cost of 6 GLS lamps Net savings per GLS point (4-5+6) Rs.1680 Rs.150 Rs.66 Rs.1596 Rs.1260 Rs.100 Rs.66 Rs1226 Rs.1029 Rs.100 Rs.66 Rs.995 480KWH 360KWH 294KWH 20W 100W 15W 75W 11W 60W

Conversion of 1 million GLS lamps of 100W to CFL of 20W reduces 80MW in peak load

Barriers to use of CFL
 Affordability

 Performance  Awareness

8 ELCOMA

Affordability
• CFL lamps cost 8–15 times more than GLS • This is down from 20-25 times only 2 years ago

• Further cost reductions shall accrue with : - Volume growth
- Concessional sales tax (VAT) of 4% - Lower component customs duties (special glass, Triband

fluorescent powder, electronic circuits) - Lower excise duties

MANUFACTURERS HAVE ALREADY REDUCED PRICE OF CFL OVER THE LAST TWO YEARS AND CAN MAKE THE LAMPS MORE AFFORDABLE WITH GOVT. SUPPORT

Performance
CHEAP CFL FROM CHINA HAD RUINED THE MARKET AND CUSTOMER HAD LOST CONFIDENCE IN CFL • The BIS standard is now in place and specifies the performance criteria • Standards have been made mandatory – to be effective 18 months from 24th August 2005 • Many local manufacturers have BIS approvals for the CFL lamps • Performance guarantees offered by manufacturers. • Labeling Program initiated by Bureau of Energy Efficiency

THE MANDATORY BIS MARKING AND ENERGY LABELLING WILL BUILD CONSUMER CONFIDENCE
10 ELCOMA

Awareness
In a survey in India barely 5% knew about CFL (Australia – 80%)  Retailers not taking pains to explain to consumers on cost benefits in long term  Public Education Program by Government not adequate  Industry ads talked only of 80% power saving

ELCOMA

Agenda for participants
Educate large Electricity Users on energy efficient lighting  Initiative to start with own buildings and installations  Involve Utilities and Users at the same platform  Short Term solution to convert GLS points by CFL  Initiate BESCOM like projects

14 ELCOMA

Agenda


contd..

 



Conduct local audit of energy consumption Work out plans for immediate replacements of GLS points with CFL or FTL Carry out educational programs in local areas through Power Supply utilities (Message in the Electricity bill) Organize long term payment schemes for consumers like BESCOM, through local suppliers or Power Finance Corporation
