We have undertaken the attempt to define the readiness level of activities and
technologies in the electricity sector. That is to say, we try to identify the activities and
technologies which still need research and those that are already widely available. We
defined four levels or readiness:
x early (in R&D level),
x young (pilots and field tests exist),
x existing (available commercially, from at least one vendor, early adopters are
involved),
x mature (widespread commercial).
“Mature” does not imply the tools can no longer be developed further but rather that it is
working and well available. Table 5 below lists our assessment of the readiness of the
different tool categories
