Value stacking energy storage Zimbabwe

What is a value-stacking project?

Value-stacking is a multi-use approach to energy where a BESS (Battery Energy Storage System) project can help defer the need for new transmission by meeting a portion of the peak demand with stored energy during select hours in the year.

Can service stacking improve energy storage system integration?

Service stacking is a promising method to improve energy storage system integration. There are several interesting cases where service stacking is crucial. Frequency supportive services are the most common to add when expanding portfolios. There is no standard method to solve optimization of service portfolios.

Is service stacking a good investment?

To ensure that an energy storage investment is guaranteed a reasonable payback period and a good return of investment it is advantageous to consider the possibility of service stacking. By offering additional services in turns or in parallel with the main service it is possible to create important revenue streams.

Is service stacking a good option for storage units?

Storage units that are operating mainly for a service with large seasonal variation, service stacking has a great potential to be implemented. RES integration and T&D investment deferral are two examples of such services which both include large annual variations.

What is service stacking?

Service stacking, alternatively value stacking or revenue stacking, is a promising method to optimize and maximize the technical and economic potential of an ESS. The aim is to find one or more additional services which the ESS can provide, besides of the main service. Offering additional services results in higher degree of utilization of the ESS.

Is service stacking a good idea for a power demanding main service?

The opposite is valid for a power demanding main service. One interesting approach is to consider service stacking already during the dimensioning process. This approach requires an optimization of the storage size given the specified portfolio, accounting for all relevant services included.
