Distribution Business is at a Crossroad becauseof emerging technological and market trends

”It will also require reconsidering of the role of DSOs. In particular it needs to beensured that their regulated activities are limited to tasks which are best performedby a natural monopoly and that new services made possible by new technologies

are developed in competitive markets.”

The massive growth of DG from RES in ItalyA changing environment with new challenges…

The increased share of RES connected urgently requires the evolution of the distribution network management

The ambitious national support schemes for Low-carbon generation has led to a significant market penetration of distributed generation (DG) from renewable energy sources

Enel’s Smart InfoCustomer awareness

Enel smart info®

1. Plugged into any electricity sockets in the house

2. Makes consumption or generation data available

3. Univocally associated to customer’s own meter

Ensures customers have easy access to complementary information in real time and historical energy consumptions allowing detailed self-checks

Certified metering data are made easily accessible to market players in a not discriminatory way to provide new services and implement energy efficient improvement measures (e.g. in-home automation, active demand, etc.)

Fully exploiting a consolidated smart metering infrastructure, Enel has developed a new generation of solutions

… what is needed now are the right regulatory and market conditions,

financial incentives and a common vision to press ahead with large-scale projects

Market and RegulationPublic awareness and acceptance

Standardization and integration Business case and Financing

Difficult to accelerate Smart Grids deployment

without revising the regulatory frameworks

Fundamental bringing the customer on-board

European/international interoperability and

technology integration not only technology

innovation

Huge investment needs and large demonstrators need to be supported to accelerate

Smart Grids development

Some challenges need to be addressed for further Smart Grids development…
