Energy efficiency and demand-side management

Date of investment




At a glance

Energy efficiency project based on the replacement and improvement of public lighting in the town of Graus (Huesca) to reduce electricity consumption, improve energy efficiency and reduce its carbon footprint.



Energy efficiency through LED lighting generates significant energy savings and reduces energy costs. It also helps to reduce the light pollution we suffer in cities.


The implementation of smarter and more efficient public lighting systems results in reduced energy consumption, allowing municipalities to manage costs while reducing their dependence on fossil fuels. All this contributes to reducing emissions, light pollution and improving air quality, bringing benefits to both citizens and society at large.

How much

This action resulted in a 50% reduction in the municipality’s energy consumption and an improvement in the quality of lighting, which has improved the well-being of citizens.

Core SDGs


The implementation of energy efficiency solutions significantly reduces emissions, but some solutions rely on fossil fuels and may be constrained in the future due to environmental regulations and taxes. The environmental benefits of electricity efficiency measures depend on the evolution of the electricity mix towards renewable sources.
