Who each solution is for
When to choose Fusebox OS
Choose Fusebox OS if you are a utility, BRP/BSP, aggregator, EPC, IPP or asset fund that:
-
Wants to build and run your own EMS + VPP and flexibility business rather than outsource it to a DR operator long term.
-
Needs one orchestration layer across PV, BESS, flexible loads and EV charging, including coordinated EV charger + BESS strategies at sites.
-
Plans to operate across multiple TSOs and countries with your own commercial models and partner choices.
-
Needs multi-tenant and white-label capability to serve many customers and portfolios.
-
Wants fast time-to-revenue, typically 1–6 months depending on whether new TSO connections must be built.
When to choose Prelect
Choose Prelect if you are a C&I or industrial site owner in the Nordics, or a local energy company, and:
-
Primarily want a turnkey DR and flexibility service for reserve markets with minimal internal build-up.
-
Prefer Prelect to handle aggregation, dispatch, TSO interaction and compliance and share revenues with you.
-
Do not plan to build internal EMS + VPP capabilities in the short term.

WHERE FUSEBOX OS WINS
Fusebox enables utilities and aggregators to own the flexibility capability: customer relationship, commercial model, data and optimisation logic, and the choice of BRP/BSP and trading partners. Prelect is a service-led operator model.
Fusebox provides site-level control and optimisation for PV, BESS, flexible loads and EV charging. This matters when value depends on coordinated site behaviour, not only responding to DR events.
Fusebox supports partner and white-label models for operating many customer portfolios under one platform. Prelect’s service model is not designed to be licensed and branded as a platform by third parties.
Fusebox is designed for multi-TSO and multi-country scaling. Prelect’s operating model is primarily anchored in the Nordics, where it runs programs directly.
