About Cubex Energy
One partner from hardware to revenue
Cubex Energy builds, finances and operates battery storage for Europe's flexibility markets. We turn stored energy into revenue through frequency regulation, capacity reserve and energy arbitrage. Every system is engineered for local grid codes and market rules, for commercial and industrial sites and for storage investors alike.

Flexibility projects
Storage assets for Europe's power markets
We take storage projects from site to revenue. We secure the site, grid access and market entry, finance the asset, build it with an efficient supply chain and local delivery, then operate it for the long term with Cubex EMS and our trading partner.

- Energy trading and arbitrage
- Capacity reserve
Funding capability
Capital to build what we design
Through our Hong Kong capital hub, we finance storage projects as well as building them. Our investment platform focuses on European power markets, with priority on frequency-regulation storage. Its capital comes from a diversified mix of institutional funds and international private investors.
Project pipeline
100+ MW
Assets under an investment agreement for Europe's ancillary services markets
Cubex EMS
One system linking site, grid and markets
Cubex EMS takes in TSO and BSP dispatch signals and on-site solar and load, and runs each system on site. It sends live data to our trading partner's platform and carries out the charge and discharge commands it receives. Our partner bids the asset into ancillary services, capacity and power markets.
Built in-house
We own the core technology.
Local BSP integration
We integrate and commission with local European BSP software.
End-to-end data links
Grid dispatch and trading platforms in one data path.
Market-ready
Live data and fast command execution, so our trading partner can bid the asset into several markets.
Proven technology, local delivery, global capital
We are growing our project portfolio in Europe's flexibility markets, to help build the stable, renewable-ready power system Europe needs.
