What Checkwatt AB does
Checkwatt AB is a Swedish energy technology company that operates a cloud-based virtual power plant (VPP) platform aggregating distributed energy resources — primarily residential, commercial, and utility-scale batteries, alongside solar, wind, and EV chargers — for participation in electricity grid services. The company connects customer assets via its CM10 gateway hardware and integrates with 50+ brands of batteries and inverters (including Pixii, Sungrow, Solax, Sigenergy, Kostal, iPotisEdge, Kehua, and SAJ), then dispatches the aggregated portfolio using AI-driven optimization across multiple revenue streams: ancillary services to Svenska kraftnät (FCR-D, FCR-N, FFR, mFRR), local flexibility to regional grid operators, solar self-consumption, and electricity price arbitrage. As of the latest data, the platform manages 15,000+ installations and 300+ MW of capacity, holds 200+ ancillary service pre-qualifications, and supports the largest connected VPP footprint in Sweden.
The company's commercial model is built around a transaction-based take rate on ancillary service revenue (approximately 25% fee plus 15% safety margin in bidding and a 60 SEK/month fixed fee), supplemented by hardware sales (CM10 gateways, electricity meters, irradiance sensors) through an exclusive partner webshop and by subscription-style optimization services. Customer segments span residential villas (10 kW/10 kWh), commercial and industrial facilities (250 kW/250 kWh), utility-scale battery parks (1 MW/1 MWh), as well as solar producers, wind operators, EV charging operators, and industrial flexible consumption sites. Go-to-market is delivered through a certified installer partner network across Sweden, with sales engineers and customer success managers supporting partners and direct enterprise relationships. CheckWatt was founded in 2014 by Dan-Eric, remains privately held, employs approximately 60 people across offices in Göteborg and Danderyd, and is currently expanding from its Nordic core into Poland and other European markets.

Revenue model
- Ancillary Services Revenue Share: CheckWatt aggregates battery systems to provide frequency restoration services (FCR-D, FCR-N, FFR, mFRR) to Svenska kraftnät. Revenue is shared with customers after deducting approximately 25% for fees, 15% safety margin in bidding, and 60 SEK/month fixed fee.
- Local Flexibility Markets: Battery owners can sell flexibility services to local grid operators during peak demand periods (typically tens of hours per year). CheckWatt facilitates these transactions and takes a percentage.
- Energy Cost Optimization Services: AI-driven optimization for increased self-consumption of solar energy and electricity price arbitrage (charging at low prices, discharging at high prices). Generates savings for customers.
- Hardware Sales (CM10 and Accessories): CheckWatt sells hardware products including the CM10 gateway, electricity meters (Acuvim IIR, Eastron SDM630), solar irradiance sensors, and static IP addresses through their partner webshop.
