Efficienza energetica: l'impegno italiano nel rapporto AIE 2013

(Maria Antonietta Giffoni)

Tra le migliori esperienze di risparmio energetico a livello globale, l'Agenzia Internazionale per l'Energia ne ha scelto 4 italiane: quelle di Hera, Enel, Innowatio e Studio Bartucci.

"Energy Provider‐Delivered Energy Efficiency. A global stock‐taking based on case studies", così si intitola il rapporto 2013 dedicato dall'Agenzia Internazionale per l'Energia (AIE o IEA - International Energy Agency) alle migliori pratiche di efficienza energetica realizzate, in particolare, dai distributori di energia.

Secondo il rapporto, i distributori di energia hanno avuto e continuano a svolgere un ruolo decisivo per l'incremento dell'efficienza energetica negli usi finali. L'AIE ha stimato che nel 2011 essi hanno speso quasi 12 miliardi di dollari per finanziare attività di risparmio energetico.

 

 

Per quel che riguarda l'Italia, grazie al meccanismo dei Certificati Bianchi, si sono spesi oltre 260 milioni di dollari annui (cifra riferita al 2010 e al 2011 - Lees 2012). Questo impegno, che vede come protagonisti sia i distributori di energia (soggetti obbligati del meccanismo) che le Energy Service Company (soggetti volontari), ha portato l'Italia al secondo posto per numero di casi virtuosi pubblicati nel rapporto.

 

I 4 "casi studio" considerati sono riferiti alle attività svolte da due distributori: Hera e Enel; e da due ESCo: Innowatio e Studio Bartucci. Riportiamo qui di seguito le parole utilizzate dal rapporto per descrivere l'esperienza italiana.

 

"Case Study # 20: HERA SpA is a large Italian utility providing energy, water, and waste management services for 3 million customers. HERA SpA is obliged to meet annual energy savings targets under the Italian White Certificates (WhC) Scheme. In the early years of the WhC Scheme HERA met its energy savings targets through energy‐saving projects developed for its own plants and building (e.g. offices buildings, water treatment, lighting improvements, district heating and cogeneration). More recently the company has been able to apply its know‐how gained from operating its own industrial facilities (power plants, waste treatment facilities, municipal waste incinerators) to develop a suite of energy services valuable to industrial operators throughout Italy. HERA provides energy audits, develops projects, sources equipment, prepares and measurement and verification planning, and handles the paperwork needed to originate the WhC – all on a no‐fee basis. HERA and the industrial end‐user enter into an agreement regarding project development and sharing of energy savings and WhC revenues. Through this strategy HERA has maintained diversity in how it meets its energy savings obligations, producing one‐quarter of its 160,000 toe annual energy savings obligation by originating energy savings projects in partnership with industrial end‐users".

 

"Case Study # 13: Enel’s energy efficiency partnership program brings together energy efficiency suppliers (technology providers, financing, installers, and operators) with energy consumers (residential, municipal, services, and industrial customers). Retail outlets have proven an effective strategy in addressing the fragmented market of small energy consumers. Enel operates its own franchise network of more than 500 EnelSi stores which sell energy efficient services (energy analysis and audits) as well as energy efficient products (heat‐ pumps, efficient lighting, efficient appliances and motors, water saving devices) and even renewable energy (solar panels). Enel has built up the retail energy efficiency market by making EE products more affordable (through centralized procurement), distributing branded energy efficiency goods and services through franchised retailers, and through market support mechanisms including sales force training, marketing, and customer support".

 

"Case Study # 23: Innowatio is an Italian ESCO which uses an energy management portfolio approach to optimize procurement and consumption of gas and electricity for large energy users in the industrial, tertiary sector and public sectors. Innowatio provides energy assessments, detailed planning of energy requirements, and identification, development, realization and operation of energy savings projects. In partnership with Humanitas, Innowatio worked with engineers, managers and health care professionals from two hospitals in Milan and Bergamo to shape an energy management portfolio that integrated patient needs and energy savings opportunities. Such an integrated and comprehensive approach can yield savings of up to 20% without affecting the quality of health care operations".

 

"Case Study # 38: Studio Bartucci is an Italian Energy Services Company (ESCO) which has combined its knowledge of industrial process innovations with the Energy Performance Contract (EPC) business model to implement more than 60 industrial energy efficiency projects. Studio Bartucci specializes in process innovation and new technologies that result in verifiable energy savings that can be used to create energy savings certificates under the Italian White Certificates scheme. Studio Bartucci identifies process innovations with energy savings potential and then finances and installs the technology application itself, thus drastically reducing the risk of investing in new technology. ESCO and factory owner enter into an Energy Performance Contract that governs measurement of savings, how costs are recovered, and sharing of the energy savings and White Certificates revenue streams. A typical industrial process innovation would have a payback period of 3‐5 years for both the ESCO and the factory owner2.
