Can battery energy storage systems generate revenue through grid services?

Many of our customers are using battery energy storage systems to generate revenue through providing grid services. Many of our customers use battery energy storage systems to generate revenue through grid services. But how easy is it and what does it all mean? Frazer Wagg, Head of Data Services at Connected Energy, explains

Will the capital cost of residential energy storage systems fall?

A continuous fall in the capital cost of building grid-scale ESSs is also projected (Figure 2.5). Benchmark capital costs for a fully installed residential energy storage system. The capital cost of residential ESS projects are similarly foreseen to drop over the next few years (Figure 2.6).

How do you value energy storage?

Valuing energy storage is often a complex endeavor that must consider different polices, market structures, incentives, and value streams, which can vary significantly across locations. In addition, the economic benefits of an ESS highly depend on its operational characteristics and physical capabilities.

How is the lifetime revenue of ESS calculated?

The lifetime revenue of ESS is calculated considering battery degradation and a cost–benefit analysis is performed to provide investors with an estimate of the net present value, return on investment and payback period. The effect of considering the degradation cost on the estimated revenue is also studied.

How is the lifetime revenue of a battery calculated?

The lifetime revenue offered by the BESS is calculated by using the optimisation framework described in the previous subsections. As the battery operates over time, it loses active material due to repeated charging and discharging. Hence, the maximum capacity of the battery decreases gradually.

How do you calculate system value per MW?

The system value per MW for each benefit category is determined based on the C-rate of storage (Table 12). After accounting for the monetisable revenues and system value, as well as the costs of an electricity storage project, the project feasibility model should stack up the monetisable revenues and compare them to the costs.
