What Watts does
Watts generates revenue through three streams: (1) one-time hardware sales of bundled Homegrid packages (Go DKK 99,800, Family DKK 124,900, Max DKK 144,900 - approximately $14,400-$20,900 USD) plus accessories like Watts Live (DKK 299); (2) recurring software/subscription value via the Watts On app and continuous Homegrid Controller updates including automated energy trading features; and (3) professional installation services delivered by company-trained electricians, carpenters, and technicians, with feasibility studies, static calculations, and leasing/financing options available for business customers. GTM is direct-to-consumer for residential (e-commerce at shop.watts.dk plus advisor-led quote process) and enterprise field sales for commercial solar ([email protected]), with separate motions for utility partnerships embedding Watts On into meter data ecosystems. Geographic operations remain concentrated in Denmark as of 2025, with the December 2025 opening of a software competence center in Vilnius, Lithuania representing the first organizational footprint outside the home market.

Watts competitors and assessment
Company assessmentRegional players
- Tibber: Tibber is a Nordic digital electricity retailer offering dynamic pricing and a smart home app that optimizes consumption against spot prices — a software/consumer-facing complement and competitor to the Watts On app experience.
Broad incumbents
- Generac Power Systems: Generac is a leading backup power and storage provider (PWRcell, ecobee acquisition) — overlapping with Watts' backup power positioning within the Homegrid Max bundle and broader home resilience narrative.
- Octopus Energy (Kraken): Octopus Energy operates retail electricity businesses plus the Kraken energy platform (used by utilities globally) to optimize home consumption, tariffs, and grid services — a broader incumbent with overlapping software capabilities.
Direct peers
- Tesla Energy: Tesla Powerwall and Tesla App form a residential energy storage + solar + EV ecosystem that directly competes with Watts Homegrid. Both target the same residential solar+battery+EV orchestration category globally.
- Enphase Energy: Enphase IQ Battery and IQ Energy Router compete directly in HEMS with AI-driven optimization across solar, battery, and EV. Enphase also acquired a green energy SaaS provider for home energy management.
- Sonnen (sonnen GmbH / Shell): Sonnen offers sonnenBatterie + sonnenCommunity, an integrated home energy storage and VPP product. Acquired by Shell, it competes with Watts Homegrid across solar+battery+managed services in Northern Europe.
- Easee: Easee is a Nordic EV charger and home energy management company whose products share the integration logic with Watts Homegrid Charge and the broader home optimization narrative.
- SolarEdge: SolarEdge provides inverters, optimizers, batteries (via SEST250), and an end-to-end energy management ecosystem — overlapping with Watts' Homegrid Controller and inverter partnerships (Kostal, Fronius landscape).
Emerging players
- OhmConnect: OhmConnect is a US-based demand response platform that pays households to shift consumption — directly comparable to Watts' virtual power plant ambition for aggregating Danish home batteries.
- EnergieID: EnergieID is a Dutch energy data and HEMS platform that integrates with utility meters — closely comparable to the Watts On app's data aggregation layer across European utilities.
