Energiot Devices, the Barcelona-based startup specialising in the digitalisation of electrical infrastructure, has closed a €1.5 million funding round led by Inclimo, the venture capital fund focused on climate tech. The round also included participation from EASO Ventures and BStartup of Banco Sabadell, as well as Axon Partners Group, alongside support from existing investors InnoEnergy and Axel Carbon Capital.
Founded in 2017 as a spin-off from the Institute of Microelectronics of Barcelona (IMB-CNM, CSIC), Energiot has developed a new generation of IoT sensors powered by piezoelectric technology that harvests energy from power lines themselves, eliminating the need for battery replacement and periodic maintenance. This patented technology enables large-scale deployment across critical infrastructure in high-, medium- and low-voltage networks.
“This round is a turning point for Energiot. We are moving from demonstrating that the technology works to deploying it at scale with Europe’s largest operators. The confidence shown by Inclimo, EASO and BStartup, our reference investors, validates the work of recent years and gives us the resources to execute the next chapter,” said Gonzalo Murillo, CEO and co-founder of Energiot.
The funds will allow Energiot to strengthen its technical team, advance the industrialisation of its hardware, and intensify its commercial activity in markets where it already operates, including Spain, France, Italy, Belgium, Lithuania and the Netherlands. The company, which works with some of Europe’s leading grid operators, aims to consolidate its presence in these markets before expanding into new geographies.
The company currently employs fourteen people and has completed sixteen projects with ten leading electricity operators across six countries, including Iberdrola, Red Eléctrica de España (REE), Enel, and Alliander. In recent months, some of these pilot projects have been converted into contracts through tenders with Iberdrola (Spain) and Litgrid (Lithuania), competing with other technology providers.
“At Inclimo, we look for solutions that address the root challenge of power grid digitalisation. Energiot has a genuinely differentiated technology — piezoelectric self-powering is a hard-to-replicate competitive advantage — and a team with deep sector expertise. It is exactly the kind of company Inclimo wants to back from the very beginning,” said Emili Curia, Investment Manager at Inclimo.
Energiot’s business model combines hardware sales with recurring data services (DaaS) and an analytics platform (SaaS), enabling grid operators to reduce operating costs, prevent failures, optimise transmission capacity through dynamic line rating without new infrastructure investment, and facilitate the integration of renewable energy sources.
“At EASO Ventures we invest in deep tech with measurable impact on the decarbonisation of the energy system. Energiot fits precisely within our thesis: strong intellectual property, real traction with leading European utilities, and a rapidly expanding market. We are proud to support the team in this new stage,” said Teresa Gómez, Principal at EASO Ventures.
The coming months will focus on converting active pilots into deployment contracts, launching drone-based installation — planned for this year — and scaling the team to support commercial expansion. The company is also working on integrating a wind sensor directly into its device, a feature not currently available on the market, which is expected to significantly improve the accuracy of Dynamic Line Rating.
“At BStartup we support companies that combine robust technology with real scalability in demanding markets. Energiot meets both criteria: years of rigorous technical development backed by CSIC and a client base that includes some of Europe’s largest grid operators. It is a clear commitment to high-impact industrial innovation,” said Laurent Arens, Investment Director at BStartup, Banco Sabadell.
In the medium term, Energiot aims to establish itself as the leading platform for intelligent power grid monitoring in Europe, capitalizing on the regulatory momentum of the energy transition and the increasing pressure on grid operators to integrate renewable energy sources without compromising network stability. The company’s roadmap includes exploring new geographies once it has strengthened its position in its current markets, where it has already built relationships with some of the largest electricity distribution and transmission operators across other continents, including Latin America, the United States, and Asia.
