What Frank Energie does
Frank Energie is a Dutch residential energy supplier founded in 2020 and headquartered in Amsterdam, operating as Frank Energie B.V. The company provides electricity and gas to households under dynamic contracts, where energy is sold at wholesale market price on a pass-through basis and the only revenue comes from a fixed monthly fee of €7.00 per product (electricity or gas). This subscription-style, transparent-fee model is the opposite of traditional margin-loaded variable contracts and is designed for the modern prosumer household with solar panels, home batteries, EV chargers, and heat pumps.
The core technology is a proprietary optimization algorithm that integrates real-time data from multiple energy markets — day-ahead, quarter-hour, and imbalance — together with household-level telemetry and weather inputs, to automatically orchestrate smart devices. Four branded services run on this engine: Slim Laden (smart EV charging), Slim Stroom Handelen (home battery trading on multiple markets), Slim Verwarmen (heat-pump/air-conditioning optimization), and Slim Terugleveren (solar feed-in management with ~15% bonus over market price and automatic cutoff at negative prices). The platform is built around an open integration approach — supported brands include Easee, Wallbox, Tesla, Zaptec, AlphaESS, Enphase, SolarEdge, SMA, Sigenergy, GoodWe, Huawei, and others — explicitly avoiding vendor lock-in. The Frank mobile app (iOS/Android, 4.4 stars) is the unified interface for contract management, real-time pricing, device control, and a bill-predictor tool.
Distribution is fully digital and product-led: customers sign up via the website (postal-code savings calculator) or the app, with no physical retail. The company serves customers in four countries — the Netherlands, Belgium (2025), Spain (2025), and France (announced February 2026) — and reports a Trustpilot rating of 4.3 across 2,889 reviews. Independent recognition includes Overstappen.nl "Beste Dynamische Energieleverancier 2026," Keuze.nl 2025, MijnBatterij.nl 2025, and Independer "Beste Keus 2025" (third consecutive year). In 2024 the platform distributed approximately €890,000 to customers actively trading batteries, and customer savings average €181.12/year vs. fixed contracts of the five largest suppliers (Independer, 27-02-2026). Recent strategic milestones include a CSP (flexibility market) license in June 2026 and a strategic partnership with Anker SOLIX for plug-in home batteries in July 2026, with scaled cooperation with Dutch grid operators (netbeheerders) on congestion compensation.

- Dynamic Energy Pricing (Pass-through): Revenue is generated through dynamic energy contracts where customers pay the actual market price for electricity and gas. The company passes through the market price without margin markup. Revenue is primarily derived from the monthly fixed fee structure.

Frank Energie competitors and assessment
Company assessmentBroad incumbents
- Octopus Energy: UK-founded disruptive energy retailer expanding across Europe, including the Netherlands with dynamic tariffs, smart consumption services and strong tech-led brand. Closest large-scale analogue to Frank's dynamic-contract + technology-first positioning.
- Greenchoice: Dutch green energy supplier offering dynamic and fixed contracts with sustainability focus. Competes with Frank in the residential green-tariff space and offers similar app-based consumption insights, though with less emphasis on hardware-specific optimization services.
- Vattenfall (Netherlands): Swedish incumbent utility with Dutch retail operations selling dynamic and fixed energy contracts. Comparable as a large-scale residential supplier with growing dynamic-pricing offerings; not a direct niche focus on smart-device optimization.
- Eneco: One of the largest Dutch energy suppliers and a major competitor across dynamic, fixed and green tariffs. Eneco's Toon thermostat and smart home services overlap with Frank's HEMS/Slim services, though Eneco also owns generation assets and has a much broader portfolio.
Direct peers
- Tibber: Norwegian-headquartered dynamic energy retailer operating across multiple European markets including the Netherlands. Tibber sells market-passed-through electricity and gas with app-based smart consumption controls for EV chargers, heat pumps and home batteries — directly comparable to Frank's dynamic contract + smart services stack.
- ANWB Energie: Dutch energy supplier offering dynamic and fixed contracts to residential customers. Competes head-to-head with Frank in the Dutch dynamic-tariff segment and uses similar pass-through pricing plus smart-device integration messaging.
- Pure Energie: Dutch 100% green energy supplier offering dynamic contracts to residential customers. Comparable product range (electricity + gas, dynamic pricing, focus on solar/heat pump households) with a narrower smart-device optimization layer than Frank.
- Zonneplan: Dutch provider of solar panels, home batteries, EV chargers and dynamic energy contracts to residential customers. Mirrors Frank's smart homeowner segment and competes on integrated solar+battery+EV optimization, with proprietary hardware and software stack.
Emerging players
- Enphase: US-based home energy and solar inverter/battery company whose Enphase IQ platform competes for smart-home energy optimization. Overlaps with Frank's integration partner list, and Enphase's own consumption optimization could be a competitive substitute for some Frank smart-service features.
- Tesla (Energy / Powerwall): Tesla operates an integrated solar + Powerwall + EV + energy-tariff ecosystem in select European markets. Overlaps with Frank as both an energy supplier and smart home device ecosystem player, with greater vertical integration but historically less tariff flexibility.
