CHECKWATT AB

Their core work

CheckWatt is a Swedish technology SME specializing in smart energy monitoring, grid flexibility, and predictive maintenance for distributed energy systems. They develop software and analytics tools for managing prosumer assets, local flexibility markets, and microgrid operations. Their work spans from solar-heat pump system optimization to blockchain-based energy trading platforms and cybersecurity for electrical power networks. Based in Gothenburg, they bridge the gap between energy hardware (heat pumps, EVs, solar) and the intelligent software layer needed to operate these assets reliably and profitably.

What they specialise in

How they've shifted over time

CheckWatt's early H2020 work (2018-2019) centered on hardware-adjacent monitoring — predictive maintenance for solar-coupled heat pumps and resilience of electrical power systems. From 2019 onward, their focus shifted decisively toward software-driven energy markets: blockchain-based flexibility trading, prosumer aggregation, congestion management, and V2G integration. Their most recent projects also show a growing interest in cybersecurity for distributed energy networks and behavioural dimensions of energy consumption.

CheckWatt is moving from monitoring physical energy assets toward orchestrating digital energy markets and securing distributed grid infrastructure — positioning them at the intersection of energy trading and cybersecurity.

How they like to work

CheckWatt operates exclusively as a participant, never coordinating projects, which suggests they contribute specialized technical capabilities rather than driving research agendas. With 108 unique partners across 22 countries in just 5 projects, they work in large, diverse consortia — typical of Innovation Actions where many demonstration sites are involved. This makes them an accessible, low-friction partner: experienced in multi-national teams and comfortable delivering defined technical work packages without requiring project leadership.

Despite only 5 projects, CheckWatt has built a remarkably broad network of 108 partners across 22 countries, reflecting their participation in large-scale Innovation Actions with multiple pilot sites across Europe.

What sets them apart

CheckWatt combines energy monitoring software expertise with growing capabilities in grid cybersecurity — a rare dual competence among SMEs. While many companies focus on either energy management or security, CheckWatt's project portfolio shows hands-on experience with both flexibility markets and EPES (Electrical Power and Energy Systems) security certification. For consortium builders, they offer a Swedish SME perspective with proven ability to deliver in large international teams and a practical understanding of prosumer-side technology.

Highlights from their portfolio

• PARITY
  Their largest project (EUR 534K) and most technically ambitious — combining blockchain, smart contracts, prosumer flexibility markets, and V2G in a single platform.
• ELECTRON
  Addresses the critical and growing challenge of nanogrid cybersecurity, combining software-defined networking with risk assessment and certification frameworks.
• SunHorizon
  Their earliest H2020 project, establishing their core monitoring and predictive maintenance capabilities for renewable heating systems across European demo sites.
