WHERE FUSEBOX OS WINS
Fusebox controls and optimises PV, BESS and loads, aggregates them into portfolios, and runs market execution to monetise flexibility. SparkMeter focuses on metering, billing and distribution utility operations. If the goal is building a flexibility and EMS + VPP business, Fusebox is the relevant layer.
Fusebox is built for hybrid sites and complex portfolios with real-time EMS logic and constraint-aware optimisation. SparkMeter operates at meter and grid-customer level rather than at asset and hybrid-site control level.
Fusebox is designed for BRP/BSP and market-facing workflows: portfolio aggregation, dispatch, and market participation under chosen trading partners. SparkMeter is designed for tariffs, billing and grid reliability, not for cross-border market operations.
Fusebox supports multi-tenant, partner and white-label models for utilities, EPCs and aggregators that want to offer EMS + VPP products to end customers. SparkMeter is a utility platform for metering and distribution operations rather than a customer-facing EMS + VPP product platform.
WHERE SPARKMETER WINS
IDEAL CUSTOMER FIT BREAKDOWN
Who should choose Fusebox OS
-
Utilities, aggregators, BRPs/BSPs, EPCs, IPPs and asset funds in markets with active flexibility and energy markets.
-
Organisations that want to control hybrid sites, aggregate portfolios and monetise flexibility under their own commercial model.
-
Teams that may already have AMI/metering platforms and now need the EMS + VPP layer on top.
Who should choose SparkMeter
-
Small/medium utilities, microgrid operators and rural/co-op utilities focused on metering, billing and distribution operations.
-
Organisations operating in emerging or weak-grid markets where the primary priority is revenue collection and grid stability rather than market-based flexibility.
-
Teams that need AMI head-end and prepaid systems as foundational infrastructure.
STRATEGIC POSITIONING ANGLE
SparkMeter is a strong utility metering and distribution operations platform that improves revenue collection and low-voltage grid visibility, especially in emerging markets. Fusebox OS sits above the meter layer as the EMS + VPP operational backbone: it uses metering and SCADA data to control hybrid assets, aggregate portfolios, and monetise flexibility in ancillary and energy markets under the customer’s chosen commercial and market roles.
