PROJECT OVERVIEW

USAID’s energy program, Catalyzing Clean Energy in Bangladesh (CCEB)Project supports the development of a low greenhouse gas (GHG)polluting economy and promotes clean energy, energy efficiency andenergy conservation in Bangladesh. CCEB is a five-year program beginning2012 and is implemented by Deloitte Consulting LLP. The key focus of theprogram includes:

Improving the Regulatory Environment for Clean Energy DevelopmentStrengthening Analytical Capacity for Energy Sector Planning &Policy-makingSupporting Industrial Energy Efficiency Analysis and AdoptionPromoting Demand Side Management Programs for Electric UtilitiesConducting Market Analysis and Promotion of using Improved Cook stoves

SCOPE OF WORKS

1. Project identification and development 2. Walk-through energy audits at selected industrial facilities3. Investment grade energy audits at industrial facilities 4. Project Finance Facilitation 5. Follow-up technical assistance in procurement, installation & monitoring. 6. Project Implementation Oversight and Monitoring

MAIN ENERGY RESOURCES

In Steel & Re-Rolling sector the main energy resources areELECTRICITYNATURAL GAS

The source of electricity is mainlyGRID SUPPLYCAPTIVE POWER GENERATION BY GAS GENERATORPOWER GENERATION BY DIESEL GENERATOR AS STANDBY SOURCE

MAIN ENERGY RESOURCES

Natural gas is mainly used forRe-heating furnace operationCaptive power generation by gas generator

CAUSES OF INEFFICIENCIES

Non engineered design & planning•Improper sizing & improper dimensioning•Actual capacity confirmation•No energy efficiency concept•Improper placement or plan layout•Improper & non linear heating

Non professional installation•Non professional workmanship•Non trained & unskilled contractor•Copy of traditional installation

CAUSES OF INEFFICIENCIES

Poor quality materials of installation•Low price consideration•Locally available materials

Inefficient operationImproper maintenance•Lack of trained & skilled manpower•Lack of technical know how•No idea about energy efficiency

BARRIERS OF ENERGY EFFICENCY ACHIEVEMENT

Lack of owner’s interest on energy efficiencyOwners (decision making persons) are too busy to think about energyefficiency. Very hard to reach themNo perceived value for free services - Perceived as student class projectNot necessary-already doing/not needed-Negative approach ofemployeesNegative attitude of middle management for personal egoAbsence of qualified positive attitude personnel to implement energyefficiency activitiesData on energy use of systems is very limited. Industrial systems are nottypically separated metered, so the cost of their operation is not known tomanagementOpportunities to become more energy efficient are overlooked
