What Protergia does

Protergia is the electricity and natural gas supply brand and business unit of METLEN Energy & Metals S.A. (Athens Stock Exchange: MYTILINEOS), operating as the largest private-sector energy retailer in Greece with 680,000+ supply points, 85 retail stores nationwide, and an omni-channel distribution stack that includes the protergiaApp (iOS/Android), a self-serve website, dedicated phone support (18311), and a B2B field-sales team. It serves three customer segments — residential, business/SME, and large enterprise — with a portfolio spanning fixed-rate (Picasso, Value Sure), variable (Dynamic One), and dynamic industrial tariffs, plus bundled products such as Value Power + Gas and Double Energy Reward that combine electricity and natural gas supply.

The technology platform combines a billing and CRM backbone with the protergiaApp mobile/web application (consumption monitoring, Picasso MyPlan tracking, payments, meter-read submission), the QUORA AI platform for Green Energy Transition (predictive analytics, energy engagement, demand response optimization), and innovative supply-side products including Protergia V2H (Vehicle-to-Home energy flow), Demand Response Services, Sun Save energy storage, and the Chargespot public fast/ultra-fast EV charging network. Protergia Picasso, a fixed-monthly electricity bill product with 9 residential and 9 business packaging tiers and a 5% bonus kWh protection mechanism, is described as uniquely positioned in the Greek retail energy market and validated externally by Product of the Year 2026 and Energy Supplier of the Year (Energy Mastering Awards 2023).

Revenue is generated primarily via subscription/recurring commodity supply (electricity and natural gas metered consumption) supplemented by usage-based EV charging (Chargespot) and solution-driven recurring services (Helios Value photovoltaics, Heat Pumps, Smart Meters, Home Chargers, Home Care). Pricing spans €29.99/month fixed Picasso entry tiers, €0.0369-€0.199/kWh variable/fixed rates, and customized large-enterprise dynamic tariffs. The parent METLEN group provides renewable generation capacity, balance-sheet scale, and integration with regulated infrastructure (DEDDIE/HEDNO distribution operator, IPTO/ADMHE transmission, ENAON/HENGAS gas distribution), anchoring a defensible cost-to-serve and supply-mix position in a regulated but liberalized market.
