Hybridising Hydropower: Unlocking Flexibility with Battery Storage
/ producer

Years : 2023
Scope : Hydropower Producer Site Profile: 7 run-of-river plants – 2 MW each

From river flow to revenue flow: enhancing hydropower with storage and grid services

Small-scale hydro plants, especially run-of-river types with limited storage, are traditionally seen as inflexible. But when paired with smart control systems and batteries, they can become powerful contributors to grid stability and open new sources of revenue through ancillary services. This hybridisation brings both resilience and profitability to clean energy production.

Client needs

  • Demonstrate that small hydro plants can contribute to grid stability

  • Optimise production using real-time market signals and forecasting

  • Add BESS (Battery Energy Storage System) to unlock new flexibility revenue streams

Energy Pool outputs

Comprehensive support from strategy to operation for the hybrid hydro + storage system:

  • Advisory
    Technical support for battery sizing and procurement recommendations, tailored to market potential and production patterns.

  • Certification
    Guidance and execution of the certification process with the French TSO, ensuring compliance and market eligibility.

  • Operation
    Operating plan design to monetise the battery’s flexibility on ancillary services (e.g., aFRR), maximising return on investment.

  • Automation & Management
    Deployment of a fully automated EMS + PMS to manage generation forecasting, monitor market signals in real time, and control the hybrid plant efficiently.
