Company Overview

CheckWatt AB

Danderyd, Sweden

2011

Approximately 60 employees (source: linkedin.com). Revenue of 277 million Swedish kronor in FY 2024 (source: checkwatt.se).

What They Do

CheckWatt operates as an energy service company specializing in the measurement, monitoring, and control of energy storage, renewable electricity production, and flexible electricity consumption (source: checkwatt.se). The company has developed a unique "virtual power plant" technology that integrates various flexible energy resources, including residential and commercial batteries, electric vehicle chargers, solar installations, and wind turbines, to optimize grid stability and profitability (source: checkwatt.se). This innovative approach allows CheckWatt to aggregate numerous small and large batteries, enabling customers to participate in electricity markets and ancillary services that would otherwise be inaccessible due to scale limitations (source: checkwatt.se). Their flagship product, EnergyInBalance, provides a data visualization portal for customers to monitor their electricity consumption and production from various sources, enhancing user engagement and operational efficiency (source: checkwatt.se).

Projects & Track Record

CheckWatt has achieved several significant milestones in its operational history. In the winter of 2022/2023, the company successfully delivered local flexibility for the first time, utilizing a 300-kilowatt battery on the Stockholm Flex market (source: checkwatt.se). In November 2023, CheckWatt was awarded first prize in the E-Prize innovation competition for energy optimization, highlighting its commitment to advancing energy solutions (source: checkwatt.se). A major operational achievement occurred in summer 2024 when CheckWatt reached 100 megawatts of ancillary services delivery, fulfilling one-fifth of Sweden's total FCR-D ancillary service demand (source: checkwatt.se). The company also connected its 10,000th site to its virtual power plant, showcasing its rapid growth and integration capabilities (source: checkwatt.se).

Recent Developments

In April 2025, CheckWatt was acquired by Emaldo Power, creating the Nordic region's largest renewable energy aggregator (source: checkwatt.se). This strategic merger combines Emaldo's energy management solutions with CheckWatt's expertise in virtual power plants and grid balancing, ensuring continued investment in development and expansion into new European markets (source: checkwatt.se). Prior to this acquisition, CheckWatt reported a remarkable revenue growth of 146 percent in 2024 compared to 2023, driven by its aggregation services for approximately 15,000 customers (source: checkwatt.se). The launch of CheckWatt AI in February 2025 marked a significant technological advancement, integrating AI-driven forecasting with ancillary service delivery (source: checkwatt.se).

Working There

CheckWatt employs approximately 60 staff members, indicating a diverse organizational structure that includes technical and business functions (source: linkedin.com). The company maintains offices in both Stockholm and Gothenburg, suggesting potential hiring opportunities in these locations (source: checkwatt.se). The culture at CheckWatt is mission-driven, focusing on enabling households and businesses to contribute to a stable, renewable energy system (source: checkwatt.se). The emphasis on innovation and technical excellence is evident from their recent E-Prize award and the implementation of cutting-edge AI solutions, positioning CheckWatt as a leader in grid flexibility technology (source: checkwatt.se).
