Your Resources. Your Market. UltimateBox Powers the DER Infrastructure

UltimateBox does not participate in local VPP market trading or settlement. We focus on DER aggregation, orchestration and dispatch, helping you turn more distributed DER into operational and dispatchable flexibility resources.

Reach More Existing DER and Expand VPP Enrollment Opportunities

Beyond aggregation, we can also help you access more flexible DER resources.

Through UltimateBox's connected global OEM ecosystem, VPP Operators can access more installed solar, battery and EV resources and bring them into their VPP platforms for aggregation, control and dispatch—accelerating the growth of dispatchable DER portfolios.

UltimateBox currently has access to a potential collaboration pool of more than 1 million residential energy inverters across Europe.

Unlock More Flexible Capacity from Every Home

UB Box connects and coordinates more controllable devices within each home, continuously expanding the flexibility available from a single household and turning every home into a richer source of flexible capacity.

UB Flow aggregates and dispatches these resources as a unified portfolio, helping VPP Operators unlock more flexible capacity from their existing customer base and improve both portfolio scale and asset utilization.

A broader mix of controllable loads also provides more resource combinations for different dispatch windows and market requirements.

Complete Technology Capabilities for VPP Operations

UltimateBox has successfully deployed and validated VPP projects, with a complete technology stack covering customer enrollment and authorization, device integration and asset management, DER aggregation and orchestration, dispatch execution, portfolio operations, and earnings and payout management.

For partners that already have the required local VPP market access and trading qualifications, UltimateBox can provide end-to-end technology support from customer-side onboarding through DER operations, while flexibly complementing your existing systems with the modules you need.

No need to build from scratch—launch and operate your VPP business faster.

Dispatch Decomposition: Turn Connected Capacity into Deliverable Capacity

Based on real-time DER status, device constraints, flexibility assessments and device-level control capabilities, UB Flow dynamically decomposes MW-scale VPP dispatch targets into executable kW-level actions across individual homes and devices.

During execution, UB Flow continuously optimizes the resource mix, corrects deviations and compensates for under-response, while returning the telemetry and execution data required for performance verification.

Deliver more reliable, market-ready capacity from the same DER portfolio.

Why UB Flow

Continuous Operations Are the Product

Energy prices, device ecosystems, market rules and customer behavior are constantly changing.

That is why a successful energy business cannot rely on a one-time software delivery. It requires continuous operation and adaptation.

Unlike traditional software vendors, our work truly begins after deployment.

UB Flow continuously evolves across devices, markets, tariffs, algorithms and energy-market capabilities, helping partners adapt to changing market conditions, create long-term value and reduce the ongoing cost of market participation.

OEM Ecosystem Expansion

Continuously onboard new OEM resources.

Ongoing protocol integration, control validation and compatibility testing continuously expand the pool of flexible DER available to your business.

New Market Expansion

Continuously adapt to local energy regulations, tariff structures, device ecosystems and business models, helping partners enter new energy markets faster.

Market & Regulatory Adaptation

Continuously track settlement mechanisms, flexibility markets, VPP dispatch requirements and regulatory changes, translating new market requirements into system strategies and operational capabilities.

Dynamic Tariff Integration Across Markets

Support for diverse tariff structures and real-time price updates enables local pricing mechanisms to be quickly translated into executable energy strategies when entering new markets.

Continuous AI Optimization

Using continuously accumulated device and energy data, we improve load forecasting, price forecasting, cost optimization, retail energy optimization and dispatch algorithms through ongoing iteration and validation, enabling smarter asset operation and greater long-term value.

Energy Orchestration Model Upgrade

As more device, market, and performance data continuously flows into the system, we keep improving available-capacity assessment, constraint identification, and resource portfolio optimization, making each dispatch decision more closely aligned with actual deliverable capacity.

Turn Partner Reach into Dispatchable Capacity

UB Flow connects VPP operators with OEMs’ installed device fleets and energy retailers’ customer portfolios, then standardizes device integration, customer activation, dispatch execution and performance verification through one orchestration layer.
