Cost of energy storage diesel

Which energy storage technologies are included in the 2020 cost and performance assessment?

The 2020 Cost and Performance Assessment provided installed costs for six energy storage technologies: lithium-ion (Li-ion) batteries, lead-acid batteries, vanadium redox flow batteries, pumped storage hydro, compressed-air energy storage, and hydrogen energy storage.

Does energy storage reduce fuel consumption?

When assessing the use of energy storage to reduce fuel consumption from associated DG, the cost function should include generator fuel consumption as this is the main operational cost. This necessitates that constraints should be added to reflect fuel consumption with the power output of the generator (s).

Should a diesel generation facility be based on cost?

Assumptions also need to be made with regard to costs. A major source of risk in the future for a diesel generation facility is the price of diesel. Given that cost savings achieved by coordinated operation of diesel generation and BESS can be marginal (e.g., 5% of fuel consumption), the price of fuel becomes extremely relevant.

What are the different types of energy storage costs?

The cost categories used in the report extend across all energy storage technologies to allow ease of data comparison. Direct costs correspond to equipment capital and installation, while indirect costs include EPC fee and project development, which include permitting, preliminary engineering design, and the owner’s engineer and financing costs.

How much would a diesel battery cost?

At current wholesale diesel prices of US$0.56 l –1 and ignoring environmental damages, all-inclusive electricity prices would need to approach US$0.056 kWh –1 with battery prices at US$100 kWh –1 and US$0.074 kWh –1 with battery prices at US$50 kWh –1 to compete with diesel.

Are energy storage systems cost estimates accurate?

The cost estimates provided in the report are not intended to be exact numbers but reflect a representative cost based on ranges provided by various sources for the examined technologies. The analysis was done for energy storage systems (ESSs) across various power levels and energy-to-power ratios.
