Ms Pi, as a recent business school graduate, you helped found the Holaluz start-up. Today, the company is a pioneer of the transition to clean energy in Spain and a top player in the field of solar energy. What was the inspiration behind it?
Carlota Pi: We want to use Holaluz to shape a world that is 100% driven by renewable energies and decarbonise the economy. Because the previous energy system has collapsed and we are in the middle of the climate crisis. Our answer is the Rooftop Revolution, a movement that is driving the transition to clean energy in Spain. We are now able to generate solar power from around 12,500 customers’ roofs across the country. We use our innovative technology platform and local power grids to connect these to households in their area that have no available roofs.
Your approach allows prosumers – people who consume energy and produce it themselves – to participate in the energy market. What good is that?
Carlota Pi: That’s how we're going to democratise access to green energy. We focus on people and their needs. We want to build long-term relationships and jointly create the most impactful green energy community in Europe. To achieve this, we want to exploit the full potential of the roofs and meet the demand of green energy by scaling electricity and storage solutions. Unnecessary solar power is fed into the local power grid and distributed to around 325,000 current electricity customers without an available roof. This is sustainable and saves electricity transmission costs because we rent the power lines and eliminate longer transport routes.
What are the specific benefits for users?
Carlota Pi: Our customers have access to green energy and save electricity and network costs. We also offer flexible modules for storing the solar power – such as batteries and charging stations for electric cars – to optimise energy management. We have already installed more than 1,000 e-chargers, and one in ten new solar systems has a house battery. For our customers, making the switch has paid off when it comes to their electricity bills: three-quarters save 70% or more, and 9 out of 10 are satisfied.
