How data analytics is being used by Spanish municipalities to become more efficient and renewable

FuturENERGY July-September 2020

The electricity bill represents a significant expense for city halls and in most cases there are clear opportunities for saving. But this is difficult to manage if measurements are not taken, so city halls that are leading the way in energy efficiency and saving have supported data analysis technologies in order to become more efficient and renewable and thereby address the climate crisis and energy poverty. ATA Insights and PylonData have brought these experiences together in the report “Data analysis for efficient and renewable municipalities”, which includes information on how to use data analytical technologies to promote municipal initiatives designed to maximise saving and energy efficiency; as well as combating energy poverty and fostering self-consumption.

The energy expenditure of municipal buildings and departments is far from being a trivial matter. For example, in 2016, the Madrid City Hall spent €33m on the energy bills of its 1,600 buildings. The energy expenditure is not only high in absolute terms, but also represents an important part of the municipal budget; around 30% of municipal costs is in supplies.

The application of energy efficiency measures is the first step to reducing greenhouse gas emissions and is essential for saving money that can then be invested into initiatives geared towards combating energy poverty and promoting renewable self-consumption.
