Energy Storage

Large-scale battery systems (BESS) can absorb volatility in the power supply and prices as well as store renewable energy obtained during periods of low demand, but high renewable generation, until there is increased demand for electricity. The establishment of storage systems therefore allows the introduction of additional renewable energy capacities accelerating the transition to a CO2-free energy future.

Our Activities

Optimization of Commercial Operation & Market Access

Axpo combines a deep knowledge of trading in the European energy markets and a long experience in assets operation together with the latest computation techniques based on AI and machine learning, to optimise the value of the storage system portfolio. Axpo identifies the revenue streams available in the individual countries, optimises the operating strategies and designs the storage systems.



Potential Revenues Streams

  • Day Ahead arbitrage
  • Intraday arbitrage

Frequency Regulation:

  • Capacity mechanism 
  • Voltage control
  • Peak shaving
  • Optimisation of grid costs
  • Imbalance management
  • Clipping reduction

Project Development and Construction Management

Axpo has the experience to develop, construct, manage and commercially operate renewables and BESS assets across Europe.

Axpo is willing to establish partnership with project developers and landowners. Please contact us if you are interested in receiving further information about such collaboration.

Standalone and Hybrid Systems

BESS managed by Axpo include standalone systems directly plugged to the main grid, and hybrid or co-located solutions where the grid connection is shared with a renewable energy source: This last one allows to utilise synergies between the assets.

Financing & Ownership

Axpo has the capability to finance storage projects partly or fully. The ownership structure is being adjusted to the individual project specifics.
