									Public Sector Energy Management
Satish Kumar, Ph.D. Lawrence Berkeley National Laboratory Public Sector Energy Management Workshop Mumbai, India
September 20, 2005

Overview
• • • • • Motivation Benefits Activities Case Studies State-wide Energy Saving Potential

Positive Impact on Power Infrastructure
• According to Indian Ministry of Power
 Power Capacity Position
• 11.3 % peak demand deficit (total installed – 112 GW) • 7% supply deficit (total installed – 520 GWh)

 Cost of building a Thermal Power Plant with 1 GW Generating Capacity = Rs. 4,000 crores (Approx. $900 million)  Energy Efficiency has the potential to create “generation capacity (negawatts)” of 25 GW by 2012 (According to Ministry of Power) = A saving of Rs. 1 trillion (Approx. $22.5 billion)

Benefits of Efficient Energy Management
• Saves government (taxpayers) money; • Reduces the gap between energy demand and suppy; • Reduces greenhouse gas emissions; • Protects the environment and natural resources; and • Contributes to the goal of energy independence.

Energy Management Activities in Public Sector
• Low-cost or no-cost measures
 Education/Awareness campaigns  Better operation and maintenance  Focus of the presentation

• Capital improvement projects
    Lighting system upgrade Replacement/Upgrade of HVAC components/system Summary report based on PWD Study Details in PWD Presentation

• Energy efficient procurement
 To be discussed in the afternoon workshop

Running an Effective Awareness Campaign

1. Plan the Effort

2. Design and implement the program

4. Sustain the effort

3. Evaluate and Report Results

Running an Effective Awareness Campaign
• Plan the effort
 Establish goals and objectives  Assess Resources

• Design and implement the program
     Gather input from staff and management Identify desired behaviour Identify what motivates people Specify activities Develop budget and schedule

Running an Effective Awareness Campaign
• Evaluate and report results
 Evaluate process  Evaluate results  Reporting and publicizing results

• Sustain the effort
    Reach newcomers Self-motivation/Awards Commitment Instituitionalization

JJ Hospital Case Study
• Venue: JJ Hospital Campus, Mumbai

• Implementing Organization:
• Classification: • Project Term:

Maharashtra Public Works Department (PWD)
Low- and no-cost Measures 2001 to 2004

• Planning Concept: Quality Circle and Deming Cycle

JJ Hospital Case Study
• Primary Energy Conservation Strategy
 Creating awareness about energy conservation
• Catchy campaigns (use of easy to remember) slogans; • Posters displayed at strategic locations (simple steps that people can take to conserve energy and minimize wastage)

• Secondary Energy Conservation Strategies
    Use of natural daylight Switching off equipment when unused Plugging air leakage in AC rooms Switching off water pumps when tank fills up

JJ Hospital Case Study
Annual Energy and Cost Savings from the Project
FY (April 1st to March 31st) FY2002 FY2003 FY2004 Total Savings Energy Savings 473,000 kWh 229,000 kWh 110,000 kWh 812,000 kWh Cost Savings Rs. 2.13 million (Approx. $50,000) Rs. 0.73 million (Approx. $17,000) Rs. 0.99 million (Approx. $23,000) Rs. 3.85 million (Approx. $90,000)

MSEB Case Study
• Venue Prakashgadh Building, Mumbai

• Implementing Organization
• Key Statistics

Maharashtra State Electricity Board (MSEB)
Area: 200,000 sq. ft. No. of People: 1,500

• Classification
• Benefits:

Low-cost Energy Conservation Measures
Energy Savings in the range of 13-29% Cost Savings in the range of 12-27% Improved Power factor

MSEB Case Study
• Energy Conservation Measures
 Changes in operating schedules  De-lamping of fixtures  Power factor correction panels  Education/Awareness campaign

MSEB Case Study
Annual Energy and Cost Savings from the Project
Year 2003 Energy Savings 318,320 kWh (13.3%) Cost Savings Rs. 1.97 million (Approx. $46,000) (12.5%)

2004
2005

326,160 kWh (13.65%)
29.6% from first five months

Rs. 3.18 million (Approx. $71,500) (19.8%)
27% from first five months

Summary of Energy Saving Proposals Prepared by PWD
• 18 Departments
 Public Health, Education, Public Works, Home, etc.

• Focus on three technologies
 E+, CFLs, Solar Street Lighting  Energy savings: 34,000 MWh/year  Total investment in projects (needed): Rs. 86.78 crores

• Macro Benefits
 Reduction in generation capacity: 18 MW  Investment avoided: Rs. 72 crores

Return on Investment on Three Technologies

Return on investment in CFL is 15x times solar street lights Return on investment in E+ is 6x times solar street lights

Energy Saving Proposals – Key Questions
• First-cost vs. life-cycle cost • Reliability and O&M issues
 CFLs  Solar street lights

• Validity of Assumptions
