WHERE FUSEBOX SYSTEM WINS

Questions

Fusebox is designed for larger portfolios and multi-country operations with repeatable processes across TSOs and products, rather than a single national retail segment.

WHERE CHECKWATT WINS

Turnkey packaged offer for Swedish households and small properties

CheckWatt’s model is well suited for end customers who want a single provider to deliver batteries/solar and monetisation with minimal complexity.

Residential and small commercial optimisation focus

CheckWatt is optimised for the needs of homes, housing associations and smaller properties, including onboarding at scale and simple customer journeys.

Strong Swedish market presence

For Sweden-focused rollouts in the residential and small commercial segment, a local provider embedded in that ecosystem can be a practical advantage.

  • Utilities, BRPs/BSPs, aggregators, EPCs, IPPs and asset funds operating C&I and utility-scale portfolios across multiple countries.

  • Organisations that want to own the flexibility business model and run EMS + VPP operations under their own brand with multi-tenant and white-label capability.

  • Teams that need hybrid-site EMS depth, demand response, and multi-market orchestration across TSOs.

Who should choose CheckWatt

  • Households, housing associations and small commercial/property owners in Sweden.
