What StackEase does

StackEase is a Paris-based, privately held battery storage optimization and aggregation company founded in 2022, focused exclusively on maximizing the net revenue of standalone and co-located battery energy storage systems (BESS) on the French public distribution network (Enedis) and broader European electricity markets. The company operates across three horizontal customer segments: battery owners seeking aggregation services to monetize their assets, battery developers requiring feasibility studies and bankable business plans for project financing, and aggregators holding EPEX SPOT or NORDPOOL access but lacking the resources to actively trade on intraday markets.

Its platform consists of four integrated solutions: Multi-Market Aggregation (dispatching batteries across day-ahead, intraday, capacity mechanism, FCR, and aFRR markets via a reserve responsible partner), Trading on Behalf (intraday trading for balance responsible parties with limited financial exposure), Long-Term Studies (revenue simulations using the same algorithms as live operations to support project IRR analysis and sizing), and Performance Monitoring (a Grafana-based dashboard for observing daily financial performance and physical state of digital twins). The proprietary optimization engine uniquely integrates TURPE variable costs, cycling constraints, and battery degradation costs into net revenue optimization rather than gross revenue.

The business model combines managed services (aggregation, trading on behalf) with professional services (long-term studies) and subscription-based performance monitoring. Go-to-market is consultative direct sales targeting French and European energy market participants, supported by content marketing and the credibility of institutional backers including INRIA, Techstars, BPI France, Réseau Entreprendre, Wilco, and Pulsalys. As of latest data, the company reports zero batteries in operation, indicating the platform is commercially nascent despite the launch of live operations in 2025.

Revenue model

1. Battery aggregation services: StackEase aggregates batteries on wholesale markets (day-ahead and intraday) via their market access and on reserve markets (capacity mechanism, FCR, aFRR) through their reserve responsible partner. The company optimizes battery dispatch to maximize net revenue.
2. Trading on behalf: For balance responsible parties and EPEX/NORDPOOL members, StackEase trades flexible assets on the continuous intraday market with limited financial exposure and open order book.
3. Long-term studies: Simulation of optimized battery revenues over the long term using the same algorithms as in operations, delivering precise, interpretable results consistent with aggregation practices.
4. Performance monitoring: Dashboard services for observing daily financial performance and physical state of battery digital twins.

Core offering

StackEase develops proprietary optimization algorithms and provides aggregation, trading, and consulting services for large-scale battery storage systems in the French and European energy markets. The platform maximizes net battery revenue across wholesale electricity markets (day-ahead, intraday) and reserve markets (capacity mechanism, FCR, aFRR) on the Enedis public distribution network, while accounting for TURPE variable costs, cycling constraints, and battery degradation.

Product overview

StackEase is a battery aggregation platform offering four integrated solutions: Agrégation Multi-Marchés for multi-market optimization, Trading on Behalf for intraday trading services, Études Long Terme for long-term revenue studies, and Suivi de Performances for performance monitoring. The platform operates batteries on public distribution networks (Enedis) in low voltage and HTA, optimizing standalone and co-located batteries across wholesale (day-ahead, intraday) and reserve markets (capacity, FCR, aFRR).

Functional benefit

Products and services

• Agrégation Multi-Marchés (Multi-Market Aggregation) Aggregation service for standalone or co-located batteries on wholesale markets (day-ahead and intraday) via StackEase's market access and on reserve markets (capacity mechanism, FCR, aFRR) through its reserve responsibility partner; the dispatch optimizer accounts for cycling limits, TURPE, and degradation costs. Designed for battery owners and developers seeking to maximize net revenue from assets on the Enedis network.
• Trading on Behalf Outsourced continuous intraday trading service for balance responsible parties and EPEX/NORDPOOL members. StackEase trades their flexible battery assets on the intraday market with limited financial exposure and an open order book, addressing clients who have market access but lack in-house trading resources.
• Études Long Terme (Long-Term Studies) Consulting studies that simulate optimized long-term battery revenues using StackEase's production optimization algorithms, ensuring projection-to-operation consistency. The service can analyze a specific configuration or size the optimal battery for a target project IRR, supporting feasibility and bankable business plan preparation.
• Suivi de Performances (Performance Tracking) Recurring dashboard service that lets users observe daily financial performance and the physical state of a digital twin of their battery site, helping them familiarize with operations and evaluate site potential from realized prices.

Scale indicators3 records

Recent moves6 records

Expansion highlights5 records

Regional players

• Piclo: Piclo operates a UK-centric flexibility matching and optimization marketplace for distributed energy and storage, comparable in concept to StackEase's optimization approach but primarily focused on the UK market rather than France.

Direct peers

• Flexcity (EDF Group): Flexcity is EDF's industrial demand response and battery aggregation arm operating across France and Europe. It competes head-on with StackEase in French BESS aggregation and ancillary services, with the backing of a major utility balance sheet.
• Kiwi Power (Engie): Kiwi Power is a UK- and European-focused flexibility aggregator acquired by Engie, providing battery and demand-side optimization across FCR, aFRR, and wholesale markets — a direct comparator to StackEase's multi-market optimization offering.
• GridBeyond: GridBeyond provides AI-driven battery and distributed energy optimization across European markets including the UK and Ireland, with both aggregation and behind-the-meter capabilities — overlapping significantly with StackEase's optimization platform and European expansion path.
• Energy Pool: Energy Pool is a European flexibility aggregator and BESS optimizer active across France and other European markets, offering multi-market optimization, demand response, and battery dispatch services — directly comparable to StackEase's core aggregation and trading business.
• sonnen eServices: sonnen (owned by Shell) aggregates and optimizes residential and commercial battery fleets across Europe, including virtual power plant operations — directly comparable to StackEase in concept, though focused more on behind-the-meter residential assets.

Broad incumbents

• Fluence: Fluence is a global battery storage system integrator and optimizer (with the MosaicOS/Nispera platform) competing in European BESS optimization as part of a much broader hardware-and-software portfolio — a broad incumbent StackEase must compete against for French developer relationships.
• Stem Inc: Stem provides AI-driven battery storage optimization software globally, including in European markets, with capabilities overlapping StackEase's net-revenue optimization, forecasting, and asset performance management features.
• EnerNOC / Enel X Way: Enel X (formerly EnerNOC) is a global demand response and distributed energy optimization platform active in European flexibility and ancillary services markets, competing for the same pool of C&I and utility-scale battery optimization customers as StackEase.
• Tesla Energy (Autobidder): Tesla's Autobidder platform optimizes Megapack fleets across wholesale and ancillary markets globally, including Europe. It is a broad incumbent whose scale and vertical integration pose a competitive threat for any independent French BESS optimizer.
