The city of Malaga generates an income of 7.5 million euros for electricity generation by the following means:

  • Biogas generated from organic waste from the "Los Ruices" Environmental Center.
  • Gas obtained in the digestion of sludge in the treatment of our wastewater (Guadalhorce WWTP).
  • 41 photovoltaic installations.

Los Ruices Environmental Center

Centro Ambiental "Los Ruices"

The plant for generating electricity from biogas from the Environmental Center of "Los Ruices" produced during 2015 the amount of 24,360,976 kWh thanks to the use of gases emanating from non-hazardous waste buried in the landfill. Of this amount, a part was sold to the supplier company and the remaining part was dedicated to the electrical supply of all the facilities and equipment in "Los Ruices", which has managed to achieve, thanks to this technology, a 98% level of energy self-sufficiency.

EDAR of the Guadalhorce

EDAR del Guadalhorce

In the Wastewater Treatment Plant (EDAR) of the Guadalhorce, electricity production reached 31,500,000 kWh in 2015 and was 38,200,000 kWh in 2016, for which around 22% of the biogas obtained in the process of anaerobic digestion of sludge was used.(renewable energy) 

Municipal photovoltaic installations

Generación Fotovoltaica

The 41 municipal photovoltaic installations (which represent a total of 535 kW of total installed power) have a double mission: on the one hand, to generate clean energy, and on the other, to play an important educational role for young people since 27 of them are located in public schools in the city. These facilities produced 507,670 KWh in 2015 and 512,700 KWh in 2016.

The plants have control equipment and inverters connected by GPRS / 3G technology (M2M network) and fiber optic network (in the case of municipal public buildings). Its operation is remotely controlled with the aim of disseminating the available information of energy generation to citizens through different means such as the Internet or screens installed in public schools.

The servers that periodically consult the information, as well as the management applications and the web servers for the publication of the results to citizens through the Internet, are housed in the Data Processing and Communications Center of the CEMI. The benefits of this action are:

  • Offer real-time information on energy infrastructures as part of the Smart City municipal strategy.
  • Improve the performance of these facilities, by having measures of their evolution depending on the different performance parameters and the ability to detect operational errors.
  • Allow efficient energy management thanks to detailed information, whose analysis allows the historical study, the monitoring of billing, or evaluate the operation of the different technologies and configurations of the facilities in the city of Malaga.
  • Serve as an instrument to raise awareness about the use of environmentally friendly energies and the promotion of savings and energy efficiency among citizens.
