What Voltiva Energy does

Voltiva Energy, S.L. (formerly MIWenergía) is a privately held Spanish energy retailer and energy services company headquartered at the Parque Científico de Murcia. Founded in 2013, the company supplies electricity to residential, business, and industrial customers across 17+ Spanish regions. Its portfolio spans indexed and fixed-price electricity tariffs (Tarifa Valor, Tarifa Estándar Reducida, Tarifa Solar, plus dedicated business and high-voltage variants), photovoltaic solar panel installation with full project management including permits and subsidy processing, electric vehicle charging point installation, and a proprietary "Batería Virtual" (Virtual Battery) system that allows customers to bank surplus energy credits and target zero-euro electricity bills. The company rebranded from MIWenergía to Voltiva Energy in 2024-2025 as part of a deliberate shift from regional to national positioning.

The underlying technology is an in-house energy management platform that integrates real-time OMIE Iberian electricity market pricing, IoT-enabled monitoring of solar and storage assets, and a mobile application providing hourly price visibility, personalized consumption alerts, and virtual battery balance tracking. On top of this retail layer, Voltiva operates an industrial solutions vertical comprising SRAD (Active Demand Response Service — covering technical analysis, auction participation, aggregation, and real-time operation), energy flexibility management, industrial energy storage, and CAE (energy savings certificate) monetization. A dedicated energy community software platform supports shared solar generation among solar communities and energy cooperatives, and the company participates in the international ACCEPT innovation project consortium.

Voltiva generates revenue through electricity supply contracts (subscription/recurring), hardware sales of solar installations and EV charging points, and managed industrial energy services. Its go-to-market combines inside sales via a free advisory phone line (900 649 086), self-service through the mobile app and online portal, a partner network of energy advisors and solar installers across 17+ regions, and direct outreach to industrial clients. Pricing is quote-based rather than publicly disclosed, and residential tariffs carry no permanence commitments — a deliberate friction-reduction posture in Spain's liberalized electricity market. The company has received PYME Innovadora certification (2024) from the Spanish Government and the Cheque-Europa 2024 grant from the European Union, validating its R&D+i program. No external funding rounds, institutional investors, or parent company are disclosed.

Scale indicators4 records

Recent moves6 records

Expansion highlights6 records

Direct peers

• Holaluz: Barcelona-based electricity retailer focused on residential solar self-consumption and green tariffs in Spain. Most direct comparison: similar residential-led GTM, indexed/flat tariff mix, and reliance on Spanish solar growth — Voltiva competes head-to-head for the same Iberian switcher.
• Lucera: Spanish 100% renewable electricity retailer with digital customer experience. Comparable as a tech-forward, green-only residential/SMB supplier directly competing for Spanish switchers seeking sustainable tariffs.
• Factor Energía: Spanish comercializadora serving both residential and business customers with transparent pricing and digital tools. Comparable because it competes in the same indexed-tariff segment, offers business-focused plans, and shares Voltiva's Spanish-only footprint and SME challenger positioning.
• Octopus Energy: Tech-led UK-origin energy retailer now operating in Spain with time-of-use tariffs and Kraken-powered smart features. Comparable because it competes with Voltiva on digitally-native, flexible/spot-linked residential and SMB tariffs and represents the 'tech retailer' archetype Voltiva aspires to.
• Podo: Spanish online electricity retailer offering simple, transparent residential and SMB tariffs. Comparable as a digital-first Spanish comercializadora with no-permanence positioning competing for the same price-sensitive segment.

Broad incumbents

• Repsol: Spanish integrated energy company with growing electricity retail and solar/EV businesses. Comparable as a Spanish full-stack competitor moving into residential solar and EV charging — directly overlapping with Voltiva's installation and EV-charger revenue lines.
• Iberdrola: Spanish/global integrated utility with massive retail and renewables presence. Comparable as the dominant incumbent in the same residential, business, and industrial tariff segments that Voltiva targets; Iberian spot exposure also overlaps with Voltiva's OMIE-linked indexed tariffs.
• Naturgy: Spanish multi-utility (electricity + gas) with broad residential, SMB, and industrial offerings. Comparable as a national incumbent competing for the same Spanish switchers and large-industrial customers.
• Endesa (Enel Group): Spain's largest electricity retailer and a major generation/retail incumbent. Comparable because Voltiva explicitly benchmarks against Endesa in customer testimonials and competes across residential, SMB, and high-voltage industrial segments — but Endesa operates at vastly greater scale and a full utility value chain.

Emerging players

• Repsol Solar360: Joint venture between Repsol and Telefónica offering residential solar and EV charging in Spain. Comparable as a newer entrant scaling solar EPC + EV charging in the same regions as Voltiva's installation business.
