BRAZIL OVERVIEW
8,500,000 SQUARE KILOMETERS
AROUND 62 ELECTRIC UTILITIES
AROUND 188 MILLION INHABITANTS
AROUND 51 MILLION CUSTOMERS
NEW COMPETITIVE ENVIRONMENT
DEREGULATION (VERY SIMILAR TO THE UK)
IURPA JUNE 2002
NON-TECHNICAL LOSSES
TOTAL (TECHNICAL AND NON-TECHNICAL) LOSSES:
BRAZIL AVERAGE 18%
NON-TECHNICAL LOSSES:FROM ABOUT 0.5% UP TO 28% (DEPENDING ON THE UTILITY)
TOTAL NON-TECHNICAL LOSSES:
1.4 BILLION US$ / YEAR
IURPA JUNE 2002
BRAZILIAN ELECTRIC GRID SYSTEM
WE USE ABOUT 13% OF THE TOTAL ENERGY USED IN THE U.S.A.
95% OF OUR ELECTRIC ENERGY COMES FROM HYDROELETRIC POWER PLANTS
OUR NATIONAL ELECTRIC SYSTEM IS INTEGRATED
IURPA JUNE 2002
2001 ELECTRICITY RATIONING WE EXPERIENCIED SEVERE ELETRICITY RATIONING (OUR RESERVOIRS WERE ALMOST EMPTY IN MAY 2001)
ACCORDING TO THE RATIONING RULES ALL CUSTOMERS HAD TO REDUCE CONSUPTION BY A MINIMUM OF 15% UP TO 25% DEPENDING ON THEIR PRINCIPAL ACTIVITY
IURPA JUNE 2002
2001 ELECTRICITY RATIONING AFTER AN INCREDIBLY GOOD SEASON OF RAIN, RATIONING IS OVER
UTILITIES HAVE HAD HEAVY REVENUE LOSSES DUE TO:
SPECIAL DISCOUNT FOR LOW INCOME PEOPLE WHO HAD DECREASED THEIR CONSUMPTION
CUSTOMERS HAD TO REDUCE CONSUMPTION BY A MINIMUM OF 15% UP TO 25% (OF THE PREVIOUS YEAR’S AVERAGE)
IURPA JUNE 2002
2001 ELECTRICITY RATIONING
UTILITIES HAVE HAD HEAVY REVENUE LOSSES
THERE WERE HEAVY PENALTIES IF CUSTOMER CONSUMPTION WAS GREATER THAN THE LEVEL ALLOCATED BY THE RATIONING RULES
IURPA JUNE 2002
NON-TECHNICAL LOSSES
INCREASED RAPIDLY DURING 2001
MAIN CAUSES:
HEAVY PENALTIES IF CUSTOMER CONSUPTION WAS GREATER THAN THE LEVEL GIVEN BY THE RATIONING RULES
IURPA JUNE 2002
NON-TECHNICAL LOSSES
INCREASED RAPIDLY DURING 2001
MAIN CAUSES (Cont.):
CULTURAL ISSUE:STEALING FROM THE UTILITIES IS OFTEN CONSIDERED NORMAL AND RIGHT (ALTHOUGH ACCORDING TO BRAZILIAN LAW IT IS A CRIME)

REVENUE PROTECTION AND NEW TECHNOLOGY
MOST OF THE REVENUE PROTECTION DEPARTMENTS DO NOT HAVE
SPECIFIC EQUIPMENT AND/OR
COMPUTER TECHNOLOGY
TO HELP IDENTIFY GENERAL PROBLEMS
IURPA JUNE 2002
REVENUE PROTECTION AND NEW TECHNOLOGIES:SPECIAL DEVICES
A WAY TO IMPROVE THE SAFETY CONDITIONS,
EFFICIENCY AND EFFECTIVENESS OF OUR
INSPECTION TEAMS
CHECK METERS WITH REMOTE RADIO READING
SOME UTILITIES ARE USING IT REGULARLY
VERY USEFUL AND RELIABLE
GIVES THE EXACT QUANTITY OF ENERGY BEING
LOST

A WAY TO IMPROVE THE SAFETY CONDITIONS,
EFFICIENCY AND EFFECTIVENESS OF OUR
INSPECTION TEAMS BY-PASS DETECTORS
STILL UNDER TESTING
GOOD RESULTS IN SPECIFIC CASES

REVENUE PROTECTION AND NEW TECHNOLOGIES:SPECIAL DEVICES
A WAY TO IMPROVE THE SAFETY CONDITIONS,
EFFICIENCY AND EFFECTIVENESS OF OUR
INSPECTION TEAMS
INTERNAL VISION CONDUIT DEVICE
GOOD RESULTS MAINLY BECAUSE MOST OF
THE FRAUDS ARE METER BY- PASSES

FOR RURAL AREAS
WHERE WE HAVE VERY LARGE DISTANCES
BETWEEN FARMS
WE ARE TESTING THE TURTLE SYSTEM

MAIN CAUSES OF NON-TECHNICAL LOSSES
BAD METERS
SOME UTILITIES DO NOT HAVE TESTING
LABORATORIES OR EVEN TEST DEVICES TO
BE USED IN THE FIELD
IURPA JUNE 2002
SOME SPECIFIC SOLUTIONS
COMPRISING OF A SPECIAL METERING BOX
(WHICH HAS A SPECIAL LENS ON THE COVER)
INSTALLED ON THE LINE POLE (10 FEET HIGH)
WICH WE ARE ABLE TO BE READ FROM THE
GROUND
A VERY SIMPLE SOLUTION THAT IS HELPING US TO AVOID LOSSES
