What Holaluz does

Holaluz (HOLALUZ-CLIDOM, S.A.; BME: HLZ) is a Barcelona-headquartered, Spanish-regulated energy retailer and solar installer founded in 2010, supplying 100% renewable electricity and natural gas to households and SMEs across Spain. Its commercial model rests on three tariff products (Tarifa Justa flat-rate, Tarifa Clásica 24-hour fixed, and Tarifa 3 time-of-use), a solar installation service under the "La Revolución de los Tejados" brand, and an integrated battery/EV-charger offering anchored by partnerships with Tesla Powerwall 3 and Sungrow. The company operates a digital-first direct-to-consumer motion: 3-minute online signup for electricity and dedicated inside-sales 900-number lines per product category, supported by a self-service customer portal and mobile app.

The technology layer is the Holaluz Cloud platform, which consumes household-level usage data from over 325,000 electricity contracts and 14,500+ solar installations to compute personalized flat-rate quotas, optimize surplus energy compensation at €0.06/kWh, and design installations from roof, geographic, and consumption inputs. Revenue streams combine recurring electricity and gas subscription/usage fees, one-time hardware sale and installation revenue (typically financed up to 25 years through partner lenders at 7.95% TIN), and transaction-based surplus compensation. Maintenance and repair services (up to €1,200/year electrical, €125/year appliance) are bundled into Tarifa Justa and sold as add-ons elsewhere, layering annuity economics onto the residential book.

Operationally, Holaluz is single-country (Spain), public-listed on BME, with 101–250 employees, a 90% customer retention rate, 4.6/5 App Store and 4.4/5 Google Play ratings, and a #1 Sustainalytics ESG ranking (January 2023) plus EcoVadis Gold Medal (July 2023). Capital structure reflects the scale-up: equity rounds in November 2024 (~$7M) and March 2025 (~$16.9M) from Icosium Investment, on top of an earlier Axon Partners Group and ENISA history, while reported EBITDA has been negative in four consecutive years, indicating an early-stage profitability profile despite a mature top-line tied to commodity pass-through.
