Energy storage
Energy storage systems turn renewable power into flexible value
An Energy Storage System (ESS) stores electricity when supply exceeds demand or prices are low, and feeds it back into the grid when demand or prices increase.
Wind and solar energy are essential, but also create fluctuations. Surpluses often occur during sunny or windy daytime hours, when production is high and demand is lower.
These moments can cause grid congestion or negative prices. A battery absorbs surplus energy and releases it when demand or prices rise, turning volatility into flexibility.
Storage is most relevant for battery investors, renewable producers combining storage with wind or solar, and industrial sites looking to optimise and monetise flexibility.
What is a cPPA?
A Corporate Power Purchase Agreement (cPPA) is a long-term energy contract that connects renewable electricity production directly to corporate consumption.Electricity generated by a renewable installation — such as a solar or wind park — is delivered “as produced”. This means the consumer receives electricity following the actual generation profile of the asset.
This creates a clear commercial link between renewable generation and corporate energy demand, supported by transparent pricing agreements and clearly defined operational responsibilities.
How energy storage works in practice
Your battery installation remains your asset and can operate as a standalone system or alongside on-site renewable generation. In many cases, it functions as a separate installation with its own grid connection. We manage forecasting, market access, activation signals and settlement, while ensuring the battery operates within agreed technical parameters.
We also connects the battery to flexibility markets and optimises its operation based on real-time market conditions. The system can:
Charge when electricity supply is high or prices are low
Discharge when electricity becomes scarce or prices increase
Provide balancing capacity when the grid requires fast response
How energy storage participates in flexibility markets

Transparency is central to the operational model. Battery owners have clear insight into:
-
Which markets the battery participates in
-
When activation occurs
-
How revenues are generated
Revenue from market participation is shared between us and the battery owner through a profit-sharing model. This aligns incentives and ensures optimisation decisions focus on maximising overall value.
Depending on the configuration, some setups may resemble a supply agreement with a predefined fee per MWh.

How energy storage generates revenue and protects against price volatility
Energy storage allows battery capacity to be deployed in short-term electricity markets where price spreads and system imbalances create opportunities.
Through smart optimisation and real-time trading, batteries can generate additional revenue while improving the overall energy position of the asset owner. Energy storage can contribute to:
-
Protection against prolonged negative price periods
-
Reduced imbalance exposure
-
Improved integration of on-site renewable production
-
Additional revenue streams from flexibility markets
Instead of passively absorbing market volatility, the battery becomes an active flexibility asset.

Why energy storage is essential for a stable energy system
Batteries provide fast and precise flexibility. They can absorb renewable surpluses and deliver power within seconds when shortages occur.
As renewable energy production increases, storage becomes essential to maintain system stability without relying on fossil-based backup generation.
Energy storage therefore plays a crucial role in balancing the electricity system and enabling further renewable growth.
