Again, and since the main focus here is on how the final consumer is directly affected by the
provision of electricity, the concentration will be on two particular indicators of quality: average
frequency of interruptions per consumer and total time of interruptions per consumer. To this
end, quality guidelines approved by the Superintendency of Electricity establish the allowed limit
values shown on Table 3.2.

The frequency indicator measures the average number of interruptions experienced by every
consumer in each of the 4 semesters of the transition period. Results are reported for two diffent
groups of operators: the first group is comprised of Cre (Santa Cruz), Electropaz (La Paz) and
Elfec (Cochabamba), the biggest distributors in the country. The second group is composed of
Elfeo (Oruro), Cessa (Chuquisaca) and Sepsa (Potosi), medium-sized distributors of electricity.
According to the frequency values of Table 3.2, the first group has an allowed limit value of 25
and the second group an allowed limit value of 35.
