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)
Government Sector: 10-20% of GDP
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
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
Venue: JJ Hospital Campus, Mumbai Implementing Maharashtra Public Works Department Organization: (PWD) Classification: Low- and no-cost Measures Project Term: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

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 crores Macro Benefits Reduction in generation capacity: 18 MW Investment avoided: Rs. 72 crores
Return on Investment on Three Technologies TechnologiesEnergy Savings (MWh) Capital Investment (Crores Rs.) Return on Investment (MWh/Crores Rs.) E+ Fittings21, CFL Fittings3, Solar Street Light Fittings 8, 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
