Energy efficiency services for the Public Administration, condominiums and companies

Through its subsidiaries Hera Servizi Energia and AcegasApsAmga Servizi Energia, the Hera Group also operates actively in the energy efficiency sector providing a broad range of services. The company mainly targets apartment buildings, large industrial customers and public administration.

Hera Servizi Energia (HSE) offers condominiums with central heating, a temperature control and heat metering system that transparently and unequivocally identifies the consumption of each individual user. To respond to the needs of energy efficiency and to faithfully report real consumption, these systems must be designed with care and made suitable to existing systems which have generally been designed several years ago and are lacking of any supporting documentation.

As of the end of 2017, 401 condominiums had installed and regularly used our control system, thanks to the professionalism and experience of Hera Servizi Energia (+19% compared to 2016). The savings expected with this system are about 17% with respect to the energy for heating, and about 13% with respect to total gas consumption (used for heating and for domestic hot water).

In parallel to its individual heat metering business, Hera Servizi Energia is active in the field of replacement of old central heating boilers with high efficiency models, that combined with the temperature control systems, significantly reduce gas consumption for condominiums. These condominiums can also have complete heat management under the “Servizio Energia” contract arrangement. At the end of the year, 88 condominiums were using the Servizio Energia service and the savings estimated by its integrated measures are about 27% with respect to total gas consumption

In Friuli Venezia Giulia, the energy services company Amga Calore e Impianti (on 1 January 2018 it merged into AcegasApsAmga Servizi Energia ASE), which operates in the same sector as Hera Servizi Energia in the area of Udine and its province, had 67 condominiums that had installed and regularly used our control system as of the end of the year. The savings estimated by using this control system are about 16% with respect to total gas consumption.

Furthermore, during 2017, Amga Calore Impianti replaced 14 old thermoelectric power stations, 5 of which using diesel and 1 using low-sulphur fuel oil, with high efficiency boilers. The savings obtained using this production and control system are about 20% with respect to total gas consumption.

In the industrial cogeneration sector, Hera offers multi-year energy supply contracts through the development and management of electricity and thermal energy production plants dedicated to meeting all the energy needs of top customers. The main product sectors in which the energy service is particularly effective are plastics, food, pharmaceuticals, ceramics and large-scale services such as museums, shopping centres, spas and condominiums.

With cogeneration and tri-generation (production of electricity and thermal energy at the same plant plus cooling services) primary energy is saved with respect to traditional consumption, emissions are reduced, energy efficiency is increased and supply costs are reduced.

HSE and ASE offer a full range of all energy carriers, making it inexpensive and easy for the customers to manage. HSE and ASE identify, in terms of the customer’s energy requirements, the characteristics of the technology plant, manage the preparation of all authorisation documents, operate and manage the plant.

At the end of 2017, 14 cogeneration plants run by HSE were operational, 3 of witch are trigeneration plants.

The environmental benefits achieved in 2017 by these plants include 14,418 tonnes lower CO2 emissions and primary energy savings of approx. 6,162 toe.
