They further reported "the levelized cost of energy from lithium-ion battery storage systems is competitive with many peak-demand generators."[80]: 23 BNEF does not disclose the detailed methodology and LCOE calculation assumptions, however, apart from declaring it is "derived from selected public sources".[80]: 98 Costs of gas peakers are substantial, and include both the cost of fuel and external costs of its combustion.
