1 The Italian experience from the first compliance period Bucharest October 17, 2028 Italian Energy Efficiency Agency

2 Legal Framework D. Lgs. 102/2014 Italy has transposed the Energy Efficiency Directive (2012/27/EU) into national law by issuing the Lgs. Decree n 102 of 4 July 2014 (G.U. Serie Generale n 165 of 18/07/2014) Art. 8 states who must carry out energy audits: Large enterprises (comma 1); Energy intensive enterprises (comma 3): only companies that have tax relief on the energy cost of the electric bill 2

6 Industrial plant energy framework (tree shape) Plant energy framework (tree shape) allows to summarize the main energy parameters, Plant is divided in three functional areas. 1. Main activities 2. Auxiliary systems 3. General Systems According to that scheme we follow the path of all energy vectors through each area 6

14 Guide Line for monitoring Guide for implementing a cost effective monitoring system Implementation of a monitoring depends on the sector each enterprise belongs to (industrial sector or service sector) and on the enterprise production area (main activities, auxiliary systems and general system) 14

15 Guide Line for monitoring Implementation of a monitoring system depends on specific enterprise according to the following criteria 1. Single site enterprises: each enterprise with an energy consumption more than 100 toe shall implement a monitoring system 2. Multi site enterprises: 1. Sites with an energy consumption more than toe shall implement a monitoring system 2. Sites with an energy consumption less than 100 toe are allowed to not implement a monitoring system 3. Sites with an energy consumption between 100 e toe shall apply sampling method 15

20 Guide Line for monitoring Monitoring system or monitoring strategy: a. Measurement campaign with temporary equipment/instrumentation : life time of a measurement campaign shall choose in order to be representative of the specific process (significance and replicability).; b. Set up of lasting equipment/instrumentation 20

21 Expected results form the next compliance period 1. Almost the same amount of energy audits 2. Better quality 3. More confident general KPIs 4. More in depth analysis of specific KPIs 21
