Fusebox OS vs Voltus

EXECUTIVE SUMMARY

Who each solution is for

Fusebox OS (Fusebox Energy)

A neutral, modular EMS + VPP operations platform for energy companies, BRPs/BSPs, aggregators, EPCs and asset owners that operate hybrid portfolios of PV, BESS, wind, EV chargers and flexible loads. Fusebox combines site-level EMS with portfolio-level VPP and market execution through a hardware-agnostic, multi-tenant platform. Fusebox is deployable globally; day-to-day delivery and support are strongest in Europe and nearby time zones, while US time-zone coverage can be provided via a paid dedicated support/operations setup.

Voltus

A North America–centric demand response and flexibility aggregator that acts as the market participant, enrolling customers into DR and capacity programs. Voltus serves industrial, commercial and institutional loads, plus some generation and storage, with strong focus on US and Canadian ISO/RTO markets.

When to choose Fusebox OS

Choose Fusebox OS if you are a utility, BRP/BSP, aggregator, EPC, IPP or asset fund that:

Wants to own a flexibility business with an EMS + VPP platform rather than outsource operations to an aggregator long term.
Needs hybrid-site control and optimisation for PV, BESS, flexible loads and EV charging, plus portfolio aggregation and market workflows.
Plans to deploy a repeatable, multi-tenant platform across many customers, countries and asset types, including aggregator-of-aggregators structures.
Wants to keep BRP/BSP and customer ownership, choosing trading partners and commercial model freely.
Operates in Europe or nearby time zones, or is willing to fund dedicated support/operations coverage for US time zones.

When to choose Voltus

Choose Voltus if you are an industrial or commercial customer in North America, or a utility serving that region, and you:

Want to quickly enrol in DR, capacity and related programs.
Prefer a turnkey service where Voltus handles enrolment, bidding, dispatch and compliance and shares program revenues with you.
Do not want to adopt and operate a dedicated EMS + VPP platform internally.

WHERE FUSEBOX OS WINS

Platform ownership instead of outsourced aggregator dependency

Fusebox is designed for organisations that want to own the flexibility capability: control of commercial model, customer relationship, data and optimisation logic. Voltus is primarily a managed-service aggregator where the provider is the market participant and controls operational execution.

Hybrid-site EMS depth and multi-asset coordination

Fusebox provides real-time EMS control and optimisation across PV, BESS, flexible loads and EV charging, including coordinated strategies like EV charger + BESS optimisation under site constraints. Voltus is focused on enabling DR and capacity program participation rather than providing full hybrid-site EMS.

Scalable platform for partners and multi-country rollouts

Fusebox supports multi-tenant and white-label deployment models suited to utilities, aggregators and EPCs running many customers and portfolios. This enables reuse of one operational backbone across geographies and customer segments.

Global deployability with clear operating model

Fusebox can be deployed globally; operational support is strongest in Europe and nearby time zones. US time-zone operations can be provided via paid dedicated support/operations coverage when required.

WHERE VOLTUS WINS

Turnkey DR and capacity monetisation in North America

Voltus provides a straightforward path for North American customers to access DR and capacity revenues with low internal effort, handling enrolment, dispatch, compliance and settlement as a service.

Deep ISO/RTO expertise and program integration

Voltus is tightly aligned with US and Canadian program structures and has expertise across ISO/RTO rules and products, which reduces complexity for customers operating primarily in those markets.

Low internal overhead and simple revenue-share models

For end customers, Voltus’ model avoids building internal DR operations teams or adopting platform tooling, making it easy to adopt for a limited set of sites.

IDEAL CUSTOMER FIT BREAKDOWN

Who should choose Fusebox OS

Utilities, BRPs/BSPs, aggregators, EPCs, IPPs and asset funds that want to build flexibility as an owned capability.
Organisations that need hybrid-site EMS plus portfolio VPP and market workflows, including EV charging flexibility coordinated with BESS and PV.
Companies scaling across asset sizes and types, including smaller C&I sites and aggregator-of-aggregators models.
Teams operating in Europe and nearby time zones, or prepared to fund dedicated support coverage for US time zones.

Who should choose Voltus

Industrial and commercial customers or utilities in North America seeking DR and capacity revenues quickly with minimal internal build-up.
Organisations that prefer a managed aggregator service rather than owning and operating an EMS + VPP platform.
Customers whose primary assets and programs are in US/Canadian ISO/RTO markets.

STRATEGIC POSITIONING ANGLE

Voltus is a strong choice for outsourced DR and capacity program participation in North America. Fusebox OS is the EMS + VPP operational backbone for organisations that want to own flexibility: hybrid-site control including EV charging coordinated with BESS and PV, portfolio aggregation, multi-tenant and white-label capability, and a global deployment model with strongest default support in Europe and nearby time zones and paid options for dedicated US time-zone operations.
