Enex Social Energy

What Enex Social Energy does

Enex Social Energy, S.L. is a Málaga-based, CNMC-registered (R2-1001) electricity retailer operating across peninsular Spain and the Balearic Islands. The company sells electricity directly to end customers under two core residential tariffs — Tarifa Plana, a fixed monthly quota personalized to historical 12-month consumption with no permanence, and Indexada, an hourly wholesale-pool (OMIE) pass-through plus a fixed operational fee — and offers a €0.15/kWh fixed-price Tarifa Empresas 3.0TD for SMBs with up to 450 kW in low voltage.

The technology foundation is a proprietary Virtual Power Plant (VPP) platform that aggregates distributed rooftop solar, residential and grid batteries, smart EV chargers, heat pumps and flexible loads across customer sites and dispatches them as a single virtual plant, buying from OMIE during low-price hours and discharging at peak hours. Core software is built in Python with Rust for performance-critical paths. Customer acquisition is 100% digital and self-serve via the 'Sube tu factura' funnel, where an AI-powered bill scanner extracts CUPS, contracted power and consumption from uploaded invoices in seconds, calculates a personalized offer, and completes onboarding through eIDAS or SMS-code digital signing.

Revenue comes from the spread between wholesale purchase (OMIE) and retail sale, with regulated peajes and taxes passed through at official CNMC rates without margin. The company is funded entirely through member contributions (aportaciones de los socios) and bank debt — no external VC/PE — and as of April 2026 reports 14,328 connected households, 2,847 in the live VPP network, 412 businesses on 3.0TD, 312 municipalities served, and 5.8 GWh/year of 100% renewable certified volume, equivalent to ~0.002% of national consumption.

Revenue model

1. Electricity Supply (Residential & SMB): Enex purchases electricity from the OMIE wholesale pool (Spanish/Portuguese market) and sells it to end customers through two tariff models: Tarifa Plana (fixed monthly quota personalized to historical consumption, guaranteed for 12 months) and Tarifa Indexada (hourly pool price plus a fixed operative fee). Revenue comes from the spread between wholesale purchase and retail sale, with transparent margin explicitized in the invoice. No hidden charges, no margin on regulated peajes, no permanence fees.
2. Business Electricity Supply (3.0TD / 6.1TD): Fixed kWh pricing for business customers on 3.0TD (up to 450 kW) and 6.1TD (>450 kW) tariff structures. Currently offering 0.15 €/kWh fixed for 12 months for 3.0TD customers, with regulated peajes passed through at official CNMC rates without margin. Tariff structure enables 30% bill reduction vs. prior provider. No permanence, no operative quota.
3. VPP Community Savings Distribution: The VPP generates collective savings by optimizing when the community buys, stores, and discharges electricity. Savings are distributed monthly as a line item on the invoice: fixed portion based on consumption, variable portion based on self-generation and battery capacity contributed. This is a cost-reduction mechanism rather than a direct revenue stream, but it drives customer acquisition and retention by providing tangible economic benefit beyond commodity supply.

Core offering

Enex Social Energy is a CNMC-registered electricity commercializer (code R2-1001) that purchases electricity from the OMIE wholesale pool and resells it to Spanish residential and business customers under two residential tariffs (Tarifa Plana fixed monthly quota and Tarifa Indexada hourly pool price) and a fixed-price 3.0TD business tariff. The supply is differentiated by a proprietary Virtual Power Plant (VPP) that aggregates distributed solar panels, batteries, and flexible consumption across connected households to optimize collective energy costs, with savings distributed monthly to participants. All customer acquisition and contracting is fully digital via the website and Progressive Web App, with no commercial agents, no permanence, and 24-hour supplier switching.

Product overview

Enex Social Energy operates as a decentralized electricity retailer offering two residential tariff products (Tarifa Plana and Indexada) backed by a proprietary Virtual Power Plant (VPP) platform. The VPP aggregates distributed solar panels, batteries, and flexible consumption across thousands of connected households to optimize collective energy costs. The enex App (PWA) provides real-time bill tracking, pool price visualization, and tariff management. Business customers are served through the 3.0TD fixed-rate tariff. The company also provides commercial and technical support services for established energy communities (CELs/CERs) as a registered commercializer (CNMC R2-1001).

Products and services

• Tarifa Plana (Flat Rate Tariff) Fixed monthly quota electricity tariff personalized to each customer's 12-month historical consumption, guaranteed for 12 months with no surprises month-to-month. The quota includes energy, regulated access charges, counter rental, electricity tax, and VAT, with annual adjustment in which under-consumption is refunded and over-consumption is prorated. Includes 100% renewable certified electricity and monthly VPP community savings reflected on the invoice. No activation fees, no permanence, no commercial agents. Product is for Spanish households (2.0TD) switching from their incumbent supplier.
• Tarifa Indexada (Indexed Tariff) Electricity tariff tied to the real-time OMIE wholesale pool price hour by hour plus a fixed operating fee from Enex. Customers pay the actual hourly wholesale cost without hidden margins; the enex PWA provides a 24-hour OMIE price curve for visibility. Designed for households that can shift consumption to off-peak hours and maximize savings from the VPP's collective buying. Available to Spanish residential customers (2.0TD) with no permanence, no operative quota, and pass-through of regulated peajes and taxes at official rates.
• VPP (Virtual Power Plant) Platform Distributed energy aggregation platform that coordinates solar panels, batteries, and flexible consumption across thousands of connected households to buy electricity at low-cost hours and discharge during peak hours. The dispatch software, built in Python with Rust performance-critical paths, sends charge/discharge commands minute by minute to minimize collective costs. VPP community savings are distributed monthly as a line item on each member's invoice. Beneath all customer-facing tariffs, the VPP is the operating backbone that differentiates Enex's pricing.
• App enex (Progressive Web App) Progressive Web App that lets customers track live invoices in real time, visualize the 24-hour OMIE pool price curve, monitor community battery status, and toggle between Tarifa Plana and Tarifa Indexada with one tap. Installable as a native-feeling app on iOS and Android without App Store requirements; uses push notifications only for service updates and active client alerts, with no advertising or third-party tracking. Functions both as an acquisition tool (comparator mode) and as the day-to-day retention tool for active clients.
• Tarifa Empresas 3.0TD (Business Fixed Tariff) Business electricity supply tariff at €0.15/kWh fixed for 12 months across all periods for small and medium businesses (PYMEs) on 3.0TD (low voltage, contracted power up to 450 kW, six time periods). Regulated peajes P1–P6 are passed through at official CNMC rates without margin, with no permanence and no operative quota. Engineered to deliver a 30% bill reduction versus a typical prior provider (e.g., Bar La Esquina S.L. saving 1,041 €/year versus its prior 285.40 €/month bill). Industrial customers on 6.1TD (>450 kW) are handled via custom-quoted engagement through the same channel.
• Comunidad Energética (Energy Community Commercializer Service) Advisory and authorized commercializer service for constituted renewable energy communities (Comunidad Energética Renovable / CER or Comunidad Ciudadana de Energía / CCE). Enex acts as the CNMC-registered commercializer (R2-1001) for the community and adds the VPP collective optimization layer on top of the community's local autoconsumo (shared solar installations within 2 km), without requiring the community to manage additional paperwork or seek a separate supplier. Designed for energy community administrators seeking additional savings beyond collective autoconsumo.

Direct peers

• Audax Renovables: Spanish renewable energy retailer serving residential and SMB customers across Iberia with 100% renewable tariffs and self-generation offerings. Direct competitor in the retail supply space with a much larger capital base and broader energy services portfolio.
• Lucera: Spanish 100% renewable electricity retailer targeting residential customers with transparent, digital-first onboarding. Competes head-to-head with Enex on flat and indexed tariffs, no-permanence positioning, and online self-serve acquisition.
• Cambio Energético: Spanish renewable energy retailer focused on residential customers with solar and 100% renewable tariffs. Comparable to Enex as a smaller-scale green retailer operating in the same CNMC-regulated market with similar anti-incumbent positioning.
• Holaluz: Spanish publicly-listed green electricity retailer offering 100% renewable flat and indexed tariffs to residential customers. Closest direct competitor to Enex in the neoeléctrica category, with similar product-led, no-permanence positioning and growing VPP ambitions in Spain.

Broad incumbents

• Iberdrola: Spain's largest vertically integrated utility with a broad renewable portfolio, regulated and liberalized retail tariffs, and growing VPP initiatives (Iberdola's 'Iberdrola Soluciones'). Provides the dominant competitive context Enex operates against.
• Repsol: Spanish integrated energy major that has entered residential electricity supply with renewable-focused tariffs (Repsol Solar, Repsol Luz). Provides a well-capitalized incumbent competing for the same anti-oligopoly-conscious residential customer base.
• Naturgy: Spanish incumbent gas and electricity retailer with growing renewable supply portfolio and CER/CCE commercializer services. Competes with Enex in both residential supply and emerging energy community (CER/CCE) market segments.
• Endesa: Spanish incumbent utility (part of Enel Group) serving tens of millions of customers with broad retail and renewable offerings. Endesa's One Lumens and Endesa Energía XXI segments overlap with Enex's residential and SMB supply proposition at much greater scale.

Others

• SunPower (Maxeon): Global residential solar and storage provider with VPP aggregation capabilities via its Energy Services platform. Comparable to Enex on the DER aggregation and residential solar storage technology stack, though geographically focused outside Spain.

Emerging players

• Octopus Energy: UK-founded digital-first energy retailer that has expanded into Spain with smart tariffs, no-permanence pricing, and VPP integration via Kraken platform. Comparable on the PLG, technology-led model and represents the most credible well-funded entrant Enex must defend against.
