INTRODUCTION
 Transformer most important link in the
power system
 Energy saving potential
 Conventional method to determine cost
effectiveness
 Total Owning Cost (TOC) concept
 Reduction in losses leads to higher capital
cost
TRADITIONAL CONCEPT (1)
 Traditional utility markets convinced about
significance of energy efficient
transformers
 The Netherlands, example for reduction in
losses in last decade

UTILITIES’ DILEMMA
 Forces of de-regulation, liberalization and
privatization
 Globalization of business
 Increased threats on international level
 Conflicting goals
UTILITIES’ DILEMMA

Uncertainty of future

Falling price levels

Demand to curtail
capital expenditure
UTILITIES’ REACTION
 Wait and watch policy
 Compromise on energy efficiency
 Staying afloat & enhance shareholder
value
 Increased emphasis on financial
performance
UTILITIES’ REACTION
 Control in the hands of commercial “Whiz
kids”
 Shorts term objectives
 KISS (Keep it Small & Simple - new
philosophy)
 Quick Gain Project
 Purchase decision by contractor
MANUFACTURERS’ DILEMMA
 Buyers’ market - over capacity
 Optimum efficiency levels achieved
 Unwise to embark on substantial
investment for new technology
 Forced to toe buyers’ line
DIFFICULT QUESTIONS
 Consequence of minimal efficiency
standard
 Manufacturers’ response to new utility
policy
 Should R&D continue for improving
transformer efficiencies
 New technology or regulatory mandates
SUGGESTIONS
Highlight
environmental
benefits
 Designate emission
reduction potential
 Abandon short
sighted approach for
better future

SOLUTIONS
 Evolve Energy Star Transformer Program
 Co-ordinated efforts by authorities,
regulator & manufacturers
 Follow Optimal Transformer Sizing Model
 Point out other advantages like less noise
pollution, compact dimensions
