For energy storage owners and investors

The value of an energy storage asset depends on the decisions made with its available capacity. Charging, discharging or keeping capacity available each creates different market opportunities. Scholt Energy connects your battery to relevant energy markets and helps optimise its flexibility within agreed technical parameters.

Energy storage turns timing into a commercial opportunity

Energy storage occupies a fundamentally different position in the electricity system from solar or wind generation. Its core value comes from flexibility: the ability to store electricity and decide when available capacity should be used.

At any moment, a battery can potentially charge, discharge or remain available for another market opportunity. Choosing one application can reduce the ability to capture another.

That makes the economics of energy storage highly dynamic. Wholesale price spreads, intraday volatility, balancing requirements, grid conditions and competition between flexible assets can all influence the value of available capacity.

At the same time, every battery has physical boundaries. State of charge, power, storage capacity, efficiency, cycling limits and availability determine which commercial decisions are possible.

The central challenge for energy storage owners is therefore continuous allocation: where should finite battery capacity be deployed, given both the opportunity now and the opportunities that may follow?

Challenges

What determines the commercial performance of energy storage?

 

Every market opportunity has an opportunity cost

Using battery capacity for one application can make it unavailable for another. An attractive wholesale trade may be less valuable if it prevents participation in another relevant market opportunity.

Energy storage optimisation therefore requires looking beyond individual trades and considering how available capacity can be allocated over time.
Price spreads change continuously

Energy storage can respond to differences in electricity prices by charging and discharging at different moments. But those spreads change as renewable generation, demand and available flexibility change.

A fixed operating schedule cannot respond fully to an increasingly dynamic electricity market.
Combining revenue opportunities increases complexity

Energy storage can potentially participate in different energy and balancing markets, subject to technical and market requirements. These opportunities cannot necessarily be captured simultaneously.

The optimisation strategy therefore needs to compare opportunities while respecting existing commitments and preserving sufficient capacity to fulfil them.
Battery operation has physical consequences

Charging and discharging are not commercially neutral actions. Cycling, efficiency, state of charge, availability and agreed technical limitations all affect how a battery can be operated.

A positive market spread alone therefore does not determine whether deploying the battery creates sufficient value.
More energy storage changes the market

As more battery capacity enters the electricity system, competition for individual flexibility opportunities can increase.

For owners and investors, this makes it increasingly important to consider access to multiple relevant markets rather than building the commercial strategy around one revenue source.

What is changing for energy storage owners?

Short-term volatility increases the importance of responsiveness

Electricity prices and system needs can change considerably between day-ahead trading and delivery.

What this means for you: the ability to adjust how your energy storage asset is deployed as market conditions develop becomes increasingly relevant.
Energy storage capacity is growing

More battery storage is entering the electricity system as the need for flexibility increases.

What this means for you: growing demand for flexibility does not mean every market opportunity will remain equally attractive. Access and optimisation become increasingly important as competition develops. 
Energy storage is moving beyond single-market strategies

Relying on one application leaves an asset exposed when the economics of that market change.

What this means for you: wholesale, intraday and balancing opportunities should be considered together where the battery and applicable market rules allow it. 
Co-located energy storage creates a different optimisation challenge

When a battery shares a site with solar or wind generation, storage interacts with production, connection capacity and the renewable asset's market position.

What this means for you: the commercial strategy should consider generation and energy storage together rather than treating them as unrelated assets.

Our take

“Energy storage value comes from preserving and deploying flexibility
Successful energy storage optimisation is not simply about responding to the highest visible electricity price.
Every decision changes the battery's state of charge, future availability and remaining operating flexibility. The value of acting now therefore needs to be considered against the potential value of remaining available for what happens next.
That requires market access, data, automated control and a clear understanding of the battery's technical boundaries.
For energy storage, optimisation is not separate from the commercial model of the asset. It is central to it.”

Why energy storage owners work with Scholt Energy

Market access and asset control come together

Scholt combines access to relevant energy and balancing markets with the systems required to control battery operation within agreed parameters. 

  
Flexible assets connect through our Virtual Power Plant

The VPP connects energy storage, renewable generation and other flexible assets, enabling their flexibility to respond to relevant market and grid conditions. 

  
Optimisation combines technology and market expertise

In-house technology and algorithms support decisions around flexible assets, while Scholt's energy-market expertise connects those decisions to changing market conditions. 

  
Energy storage can stand alone or complement renewable generation

Scholt supports both standalone energy storage and batteries combined with solar or wind generation, subject to the technical and commercial setup of the asset. 

  
FAQ

What others ask

 

Which markets can my energy storage asset participate in?

Potential opportunities include wholesale energy markets and balancing services. The markets available to a specific battery depend on its technical characteristics, qualification, location, contractual structure and applicable market rules. 
How does Scholt determine when a battery should charge or discharge?

Optimisation considers market conditions and available flexibility while respecting agreed technical parameters such as state of charge and operating limits. 
Does energy storage optimisation mean maximising the number of cycles?

No. More cycling does not automatically create more economic value. Market opportunities need to be considered alongside efficiency, technical limitations and agreed cycling constraints. 
Can an energy storage asset create value across several markets?

Potentially, yes. However, the same battery capacity cannot necessarily be committed to different applications simultaneously. Optimisation therefore involves deciding where and when available flexibility should be allocated. 
How are battery degradation and technical limits considered?

The operating boundaries of the battery form part of the optimisation setup. The specific treatment of degradation, warranties and cycling constraints depends on the individual asset and its technical conditions. 
Can Scholt optimise energy storage alongside solar or wind generation? Yes, subject to the technical and commercial setup. For co-located assets, generation, battery capacity, grid connection, metering and existing offtake arrangements need to be considered together. 
What if market opportunities change during the lifetime of my energy storage asset? The commercial strategy does not need to depend on a single market application. Access to multiple relevant markets allows the optimisation approach to respond as market conditions and opportunities develop.
