What Nexus Energia does
Nexus Energía, S.A. is a Barcelona-based electricity and natural gas retailer founded in 2000 that commercializes energy across Spain and Portugal, serving four segments: residential households (Hogar), small and medium businesses (Pymes), enterprises (Empresas), and renewable energy producers (Productores). The company sells 100% CNMC-accredited renewable electricity through five residential tariffs (Luz Estable, Luz a precio de coste, Luz Eficiente, Luz Indexada, Luz Óptima), plus fixed and indexed natural gas supply, self-consumption installations, and a virtual battery (Batería Virtual) that lets customers bank surplus renewable generation for later use. Supporting technology includes the Esfera Luz mobile app and the Zona de Cliente web portal for contract management, bill access, consumption monitoring, and CO2-savings tracking.
The business operates a recurring, mostly subscription-based revenue model combining consumption-based charges with fixed monthly management fees (e.g., €4.50/month on the market-price tariff), layered with professional services for enterprise and producer clients — energy audits, ISO 50.001 consulting, ESG/carbon-footprint reporting, demand flexibility, Energy Savings Certificates (CAE) management, PPA hedging, and wholesale-market representation. Distribution is multi-channel: self-serve web contracting, toll-free inside sales, a mobile app, and a recently opened physical retail store in Zamora opened with partner Origen Energía. The firm is majority-owned by Japanese conglomerate Sojitz Corporation and operates under a 2026-2030 Strategic Plan led by new director Miguel Fandiño, with a stated goal of doubling the business in five years and consolidating as a "Smart Energy Partner" across the Iberian market. In FY2025 the group reported €1,673 million in revenue and a record 20.8 TWh of managed energy, ranking 8th-9th among Spanish electricity and gas retailers and 2nd-largest representative of renewable producers nationally.
