The government measure for regenerating land and housing in Barcelona currently highlights the need for spearheading new energy improvements associated with renovating less efficient buildings. It therefore favours energy-generating installations that use renewable sources (solar photovoltaic and thermal energy) and other associated initiatives.

Along these lines, the new 2017 housing-renovation subsidy campaign promotes initiatives to install systems for generating renewable energy.

The City Council is therefore offering subsidies of up to 60% of the cost of voluntary installation of photovoltaic panels (for producing electricity) and solar thermal panels (for producing sanitary hot water), for both individual and collective projects. There are also subsidies of up to 60% of the cost of replacing supply services with other, more efficient ones.

Likewise, the new Incentive Programme for Generating Solar Energy in Barcelona, has also provided for a series of grants, subsidies and tax allowances to enable installations of renewable-energy systems in individual private buildings.

There is currently a three-year, 50 % discount on Property Tax (IBI) for solar-generation installations (thermal and photovoltaic) and the application of other discounts is being studied (Construction, installation and works tax (ICIO), economic activity tax (IAE) etc.)

On the other hand, work is also being carried out on several accompaniment measures, such as creating a unique window for processing energy-generating installations, simplifying management and legalisation procedures and providing more information from Energy Advice Points and La Fàbrica del Sol.
