Spanish SMEs could save more than 1,200 euros per year by changing their lighting for a more efficient type

To mark World Energy Day, Endesa has presented the 2016 Endesa Report on the Energy Performance of Spanish Companies at its headquarters in Madrid. The report shows that 81% of the Spanish SMEs have not put energy efficiency measures into practice.

This lack of awareness of Spanish SMEs is generally due to ignorance regarding as to their actual level of consumption itself, in addition to the limitations on investment in facilities and equipment to improve energy efficiency. According to Endesa’s study, one of the most important measures to improve energy performance is the adjustment and optimisation of the contracted powercapacity, which could lead to companies saving an average of 800 euros per year; with 20%. of these able to cut costs by This figure rises to more thanover 2,000 euros for 20% of the cases. 

These figures could be increased in some cases by the control of reactive energy, the energy generated by the pipes of some electric motors and fluorescent lights and which is penalised by the electrical system. This reactive energy consumption is avoided with the installation of capacitor banks, which could save an average of 400 euros per year. The Endesa study also reveals that 78% of the companies do not have equipment to compensate for this energy.

In terms of efficient lighting, the replacing of old lights with lights using LED technology would save 1,200 euros per year on average for SMEs. In 46% of the cases analysed, the investment would be recovered in less than 4 years.

In addition, most of the Spanish companies – 68% of those analysed – have no control over so-called phantom energy consumption; that is to say, over the energy consumed unnecessarily, by computer screens lit up without activity, for example, or air conditioning activated when is not necessary, or lighting in garages at night when no cars are present. If the Spanish companies were to apply control measures in this regard, they could save 1,400 euros a year.

Applying all the above measures, Spanish companies could reduce their energy consumption by 20%. Some 26% of the companies analysed by Endesa showed an even higher potential for savings. However, it must be borne in mind that the measures complement each other, and that the individual savings cannot simply be added together, given that some improvements also imply the correction of other problems. For example, replacing the lighting or the HVAC motors with more efficient equipment not only reduces consumption but can also make it possible to reduce the contracted powercapacity.

By sector, the industrial sector is the one that could save most by implementing energy efficiency measures, with an average per company of at least 2,400 euros per year. This is followed by the agricultural sector, with possible savings of more than 2,100 euros per year, and then the tertiary sector, with savings of at least 2,000 euros per year.

Investing in the saving of energy not only increases the competitiveness of SMEs but is also beneficial for the environment. Companies implementing energy efficiency measures can reduce their emissions by up to 26% in the case of the tertiary sector, by 20% in the industrial sector and by 15% in the agricultural sector.
