PURPA ayudó a establecer
requerimientos de confianza
(90 %) y precisión (±10 %) en
las estimaciones de factores de
asignación de costos seleccio-
nados, como la demanda má-
xima coincidente (del sistema)
A su vez, estos requerimientos
sentaron las bases para futuras
consideraciones con respecto a
las necesidades de confianza y
precisión para las evaluaciones
de eficiencia energética y res-
puesta a la demanda. PURPA
dio lugar a un renovado interés
en la investigación de carga y a
toda una generación de depar-
tamentos y actividades de esta
disciplina. Los investigadores
de carga que se unieron a la in-
dustria durante esta era a me-
nudo se los denominaba niños
PURPA.

En los comienzos, la instru-
mentación y la recolección de
datos resultaban extremada-
mente desafiantes. En la figu-
ra 1 se muestra la evolución del
equipo de medición, comen-
zando con los registradores
gráficos en papel en la década
de 1950. Estos fueron seguidos
por los magnetófonos de bobi-
na abierta y luego por los mag-
netófonos de cartuchos (cinta
magnética) y los registradores
de estado sólido. Hoy en día,
nos estamos acercando rápida-
mente a la información masiva
de carga a intervalos, no solo
en toda la instalación, sino en
una multitud de elementos que
rodean la existencia diaria de
un cliente.

Parcialmente en respuesta a
PURPA, AEIC, con el apoyo del
Departamento de Energía de los Estados
Unidos y el Laboratorio Nacional Ar-
gonne, comenzó a desarrollar el primer
manual de investigación de carga (Fi-

visión de los requerimientos de PURPA.
