What Gesternova does
Gesternova S.A. is a privately held Spanish renewable energy company headquartered in Madrid that markets electricity, solar, EV charging, and aerothermal heating solutions to households, SMEs, industrial businesses, and energy producers under the commercial brand Contigo Energía. The company operates through two Spanish legal entities (GESTERNOVA, S.A. and its wholly owned subsidiary GESTERNOVA SERVICIOS ENERGÉTICOS, S.A.) and has been active in the Spanish energy sector for over 20 years since its founding in 2004. Its revenue model combines recurring retail electricity supply contracts (monthly billing, quote-based pricing via an online comparator that claims 77% of users save an average of €219 per year) with one-time and project-based revenue from solar panel installations, EV charger installations, and aerothermal heat pump installations.
The company runs a digital-first go-to-market supported by phone-based inside sales (multiple 900-prefix lines plus WhatsApp), a self-serve website with a tariff comparison tool, a customer mobile app on iOS and Android, and content marketing via a blog, YouTube, and social channels. Customer segments are organized as Hogares (residential households), Empresas (SMEs and industrial clients served via 3.0TD and high-voltage tariffs), and Productores (renewable energy producers connected to the grid). Its geographic footprint is limited to Spain, with a Portuguese-language site version suggesting early-stage cross-border exploration.
Gesternova's distribution platform is described as enabling 100% renewable energy supply, but no proprietary technology or patents are disclosed. The company faces a notable regulatory headwind: in December 2024 the Spanish market regulator CNMC imposed a €6 million fine for alleged manipulation of the electricity market involving 141 GWh of non-deliverable nighttime solar power sales, a decision the company has stated it will appeal. Revenue, headcount growth, and funding data are not publicly disclosed.
