Battery storage

BESS - Battery Energy Storage Systems

BESS (Battery Energy Storage Systems) enable businesses, local authorities and industrial sites to regain control over their energy. Instead of being subject to market fluctuations and grid constraints, they store electricity when it is abundant and cheap, then consume or resell it when prices rise.

Overall
Operation

Go from a customer to a consumer

Purchasing or producing energy at a client's site.

Storage of energy in batteries combined with an energy management system (EMS).

Communication between the EMS and the market price to gain the best possible resale value.

Resale and transfer of energy into the public grid as well as within your installation.

Benefits

A. Energy independence and cost optimisation

BESS enable businesses, local authorities and industrial sites to regain control over their energy. Instead of being subject to market fluctuations and grid constraints, they store electricity when it is abundant and cheap, then consume or resell it when prices rise :

  • Reduction in purchasing costs through price arbitrage (buy low / use or sell high).

  • Reduced reliance on the network or imports.

  • Promotion of local energy production (solar, wind, cogeneration).

  • Ability to maintain autonomous power supply in the event of an outage (island mode).

Result: more controlled, more cost-effective energy that is better aligned with the site's energy strategy, designed and tailored to your specific situation.

B. Reliability and stability for income

Unlike simple renewable producers, BESS operators can generate predictable and stable revenues by combining several sources :

  • Energy arbitrage on spot markets (difference between low price and high price).

  • System services: participation in grid balancing, fast reserve, frequency, etc.

  • Capacity: remuneration for storage availability.

  • Smart PPAs: integration into supply or flexibility schemes.

The entire process, managed by an EMS and optimised through algorithmic trading, guarantees continuous appreciation of the invested capital.

Result: diversified income streams that are less exposed to market volatility and assets that generate returns over a 10- to 15-year period.

C. Sustainable and Future-Oriented

Energy storage systems fully support the European energy transition:

  • They facilitate the large-scale integration of intermittent renewable energies.

  • They reduce CO2 emissions by replacing peak fossil power generation.

  • They support the digitalisation and decentralisation of the electricity system.

  • They lay the groundwork for new applications: electric vehicles, green hydrogen, microgrids, and more.

Result: a future-proof asset that is both profitable today and essential tomorrow.
