Replacing other fuels

Significant savings were made in the past year through replacing other fuels: €3.1 million in the residential market and €3.2 million in the large consumer market. The figures translate into a total €6.3 million of savings in the proprietary distribution zone (our own calculation based on annual growth and the energy mix handled by us in the residential and large consumer markets).

The energy mix of fuels we have displaced is made up of 65% propane and butane, 20% diesel and 15% electricity.

Regarding carbon emissions, the savings achieved in 2013 translate into: 4,500 metric tons in the residential market and 7,200 metric tons in the large consumer market, making for a total of 11,700 metric tons per annum of emission savings in the Madrid region. A key fact to bear in mind: a propane-fuelled household emits 420 kg per annum of carbon dioxide more than if it were fuelled by natural gas.

Energy efficiency study

With condensing boilers, which utilize the latent heat of condensation gases and reduce natural gas usage, MRG has achieved efficiency figures in excess of 110%. This makes for energy savings of more than 25%. In addition, emissions of carbon dioxide and nitrogen oxides are up to 20% less than for a conventional low-consumption boiler, which only achieves NOx emission savings of 6%. Furthermore, maintenance costs are considerably lower.
