Regulatory measures in the new paradigm context
Autorità per l’energia elettrica il gas e il sistema idrico
The Italian electricity sector:
from liberalization to European integration
1999- Liberalization decree (79/99) following directive 92/96/CE
Unbundling
Generation: incumbent
splitting (4 GENCOs)
Transmission: ownership
Distribution: legal
Wholesale market
Public Power Exchange
(Long term - Day AheadIntra Day -Balancing)
Bilateral contracts
Retail market
Single Buyer model
Two market segments:
eligible and captive
customers
2007-Completion of retail market opening following directive 53/2003/CE:
domestic customers and SME can refer to a protection service provided by a default
supplier at prices defined by AEEGSI on a market basis
2014- Completion of Internal Electricity Market in Europe: the Italian market is going to
be integrated with other markets through day ahead market coupling

Italian electricity system in 2012: capacity
RES effects on low load days
Net installed capacity (124 GW)
Demand peak 54,1 MW (max 56,8 MW in 2007)
Measures for the balance of the grid
•Import reduction
•Pumping storage
From an energy
•RES curtailment
only market... to a capacity based market?
The penetration of intermittent RES with zero marginal costs is deeply changing the market
structure: thermo PP cannot recover fixed costs and flexibility services have to be enhanced

Regulatory measures in the new paradigm: far future regulation 1/2
General approach:
– focus on effectiveness (i.e. performance) and economic efficiency (i.e. costs):
projects are paid for by all consumers
– full transparency of procedures, rules, criteria (e.g. for project selection and
evaluation) defined and known ex-ante
– scientific and technical support (Universities, research centers; technical
Committee)
– continuous monitoring (throughout the project’s lifetime)
– replicability
– public dissemination of results

Decision 393/2013
State of the art: definition of selection criteria (number
of points, variety of services included), minimum
requirements (e.g. at least 30% of points in the gas
sector and 60% in services regulated by AEEGSI)

Drivers for the new regulation
•
Decarbonisation increases the need for flexibility of the electricity system =>
growing share of renewables
•
Expected growth of markets for electrification of mobility and heating (power to
heat) => significant increase of the peak of demand above the limits of the existing
electricity distribution networks
•
The European Directive 2012/27/EC pushes towards the integration of demand-side
flexibility (= modification of consumption patterns in reaction to an external price
signal or activation, in order to provide a service within the energy system) in the
electricity system
