Flexcity

What Flexcity does

Flexcity is a European electricity flexibility aggregator that monetizes the demand-side flexibility of industrial and commercial energy assets across Belgium, France, Italy, and the Netherlands. A subsidiary of Veolia Environnement, the company operates a proprietary platform that connects industrial facilities (such as water utilities, paper and steel manufacturers, data centers, and telecom networks) to grid operators and multiple energy markets — including aFRR and mFRR balancing reserves, capacity mechanisms (e.g., Elia CRM), and wholesale markets (intraday, day-ahead, imbalance). At the technical layer, Flexcity relies on its proprietary Flexcity Box hardware installed on client sites to execute local, decentralized control algorithms, complemented by an Energy Process Modeling module that models complex industrial processes and issues real-time control signals to respect operational constraints while optimizing for market opportunities.

The business model combines transaction-fee revenue from monetizing flexibility on behalf of asset owners with performance-based optimization fees, particularly through a 2025 strategic partnership with Vienna-based enspired that extends the offering into multi-market battery energy storage system (BESS) optimization in Belgium and the Netherlands. Flexcity captures a share of the value created (capacity payments, balancing payments, and wholesale spread) and shares a portion with clients under individually negotiated, multi-year B2B contracts. Approximately 3 GW of flexible power capacity is under management, anchored by the full selection of 350+ MW in the Elia CRM auction (>80% of demand response volumes) and the integration of 8,000+ backup batteries from Orange France.

Go-to-market is primarily direct enterprise sales supported by regional channel partnerships (AiLux and Siram Veolia for Italy) and Veolia's broader commercial footprint. Flexcity is headquartered in Brussels (Saint-Gilles) with a Paris entity (Flexcity SAS, €9.55M share capital), operates from 11–50 employees as a private subsidiary, and has GDPR-compliant operations across all four served jurisdictions.

Revenue model

1. Flexibility Aggregation and Monetization: Flexcity aggregates flexible electrical capacity from industrial consumers and prosumers, then monetizes this flexibility on various electricity markets including balancing markets (aFRR, mFRR), capacity mechanisms (CRM), and wholesale markets. Revenue is generated by selling flexibility services to grid operators (TSOs like Elia, RTE) and through capacity auctions. The company shares revenue with clients while retaining a portion as aggregation fees.
2. Multi-market Battery Optimization Services: In partnership with enspired, Flexcity provides comprehensive battery energy storage system (BESS) optimization across Belgium and Netherlands. Services include wholesale market optimization (intraday, day-ahead, imbalance), aFRR capacity and energy, and congestion management. Revenue derived from performance-based optimization fees.
