Technically the“Telegestore”

is a system of electronic interconnected equipments made of:

An integrated equipment for metering, data

transmission and data management A Concentrator of data

from the Meters. It is located in

secondary distribution substation

A Central System for data aggregation and the management of the whole process

Something will change in the relationship with customer

Availability of “Time of Use” tariffs and customised tariffs

Deregulated customer could be managed without change of assets

No more estimated bills; real time measure of consumption for each bill

Improvement of quality in commercial activities; In activation or contract changes, time goes from days to minutes

Indicators for Network Quality are strongly monitored

Opening a new communication channel to customers home in order to supply Value Added Services and measure gas, water and heat supply

Billing on real readings

Advantages for customer

Flexibility (tailored) of billing period

No wrong readings and decrease of customer dispute

Quicker solution of dispute with customer (spot reading on request)

Flexible tariff structure

Simple customer contractualisation

No need of customer presence for readings,contract activation, de activationor contractual power modification

Increase of comfort and consumption optimisation

Improvement

of Service Quality

and optimisation

of Service Cost

Advantages for the marketAll customers will benefit from the system even if they are not eligible

Demand side management (see California crisis)

Improvement of losses information, calculation and regulation

Improvement on load forecast

Improvement on new pricing initiatives

Improvement of quality of service information and regulation

Control of fraud

Improve of settlement, invoicing processes and imbalance allocation

Advantages for the Authorities: data collection

Avoiding the need of Load profiling

Improvement of guarantee of supply regulation

New metering services

More selling competition
