Energy efficiency

Energy efficiency

obiettivi Hera al 2017

Hera's commitment to a sustainable future involves investment in technologies for efficiency, containment and greater awareness of energy consumption.

In December 2014, Hera obtained ISO 50001 certification for its energy management system, issued by the DNV GL certification body that recognises best corporate practices in the efficient use of energy.
It is one of the first ISO 50001 system certifications issued in the entire business world.

A company plan dedicated to saving energy

The energy management system involves the entire Hera S.p.A. organisation, including all company premises and plants and has been part of an ambitious plan for many years: constantly monitoring the entire extent of the company and getting to know, in detail, how much energy is consumed and when and where.
An increasingly important aspect, especially from the point of view of environmental sustainability, alongside the quality and environment protection certifications (ISO 9001 and ISO 14001).



The goals of Hera's energy policy

The measures implemented are aimed at creating energy efficiency to reduce the environmental impact of the use of fossil fuels, keep down costs and stop the wasting of energy.
Specifically, the implementation of special measures to comply with the requirements of White Certificates. To date, over 45 measures capable, once completed and up and running, of generating estimated savings of over 3,000 tonnes of oil equivalent (toe) per year, have already been identified.

In-house staff dedicated to controlling the consumption of plants and buildings

Hera's energy policy has assigned the task of monitoring efficiency management to a dedicated team, which has identified over 80 consumption centres within the company, which range from the largest plants to individual buildings. Consumption monitoring has been set up for each of them through Energy Performance Indicators (EnPI), which allow the conduction efficiency of the systems and equipment to be constantly kept under control. This allows any critical areas with regard to efficiency to be highlighted and then measures to introduce improvements in the use of energy can be implemented.

Target for 2017: to reduce consumption by 3%

Aware of the fact that ISO 50001 certification should be considered a starting point and not an end in itself, Hera's target for 2017 is to achieve savings of at least 3% compared with the consumption figures recorded in 2013. Savings equal to approximately 6,200 toe per year. All Hera Group structures are therefore hard at work to increase their commitment to further improve corporate energy efficiency to make a contribution to respecting the environment.

ISO 50001


ISO 50001, International Standard for Energy Management, is the standard or scheme for Energy Management Systems (SGE or EMS in the English version). It is an internationally-developed standard for helping corporate organisations improve their performance in terms of energy, increasing efficiency and reducing the impact on the climate and the environment. The standard establishes specific minimum criteria that the EMS must satisfy. In brief, the concept can be summarised as the corporate organisation, when faced by a precise directive requirement to adopt a specific energy policy, organising constant monitoring capable of evaluating energy consumption in terms of what (what type of energy source), how much (mc, kWh, etc.), where (in which plant of part of the plant, building, etc.), and how (whether the energy performance is efficient or could potentially be improved). This is designed to identify improvement measures and to evaluate whether these actions will be cost effective in a reasonable period.




In 2013, Hera S.p.A.'s "energy bill" came to approximately 143 million euros and the most used energy sources were natural gas (46%) and electricity (38%). These were followed, in much lower percentages, by renewable sources (mainly biogas and photovoltaic self-consumption), heat from district heating and fuels. This does not include production from renewable sources by Hera Energie Rinnovabili, Herambiente (energy recovery from waste biodegradable fraction) and other Group companies, which is far more significant than the production under the scope of Hera S.p.A. subject to certification.
The budget items which recorded the highest consumption were ENERGY (57%) and WATER (36%).




There is a new frontier for the energy efficiency represented by the widespread application of the most advanced experiences of behavioral theory. A targeted, reliable information that compares ways to use energy can influence behaviors and can lead to a significant saving, as Prof. Thaler has established. After the experience with the residential market, the border to cross is now represented by the industrial sector: ideas, solutions, tools to be put together with a tailor-made approach.
The challenge has underlying rational and potential that make it attractive, however, what we need right now is the help of "architects of the choices" and enabling, consistent elements working together in order to build a "less resistance" way.
"What" and "How" from the point of view of Hera...
