- 摘要
- 隨著近年來越來越多再生能源加入電網，電力產業需要儲能設備平衡電網供需，以維持電力 系統的穩定度。電力產業除了建置電池儲能系統，可以選擇電動公車的電池作為儲能設備之替代方 案。本文分析臺灣電動公車參與B2G之營運模式下，相對於傳統柴油公車之成本有效性分析。實證 結果顯示，從使用者情境的角度，考量12輛柴油公車之固定成本與變動成本，其淨現值約為201.9 百萬元。公車業者購置電動公車，在申請政府補助的情況下，12輛電動公車之淨現值約為270.6百 萬元。若參加B2G獲得業外收入，其淨現值最高可達到277.4百萬元。因此，在使用者情境中，電動 公車係具有成本有效性。從整體社會情境的角度，12輛傳統柴油公車之總成本現值約為194.3百萬 元。扣除政府補助之移轉性支付，12輛電動公車之淨現值約為228.5百萬元。若參加B2G獲得業外收 入，其淨現值最高可達到235.9百萬元。因此，在整體社會情境中，電動公車係具有成本有效性。

- With renewable energies increasingly being incorporated into power grids, the power industry requires energy storage equipment to balance the supply and demand in power grids and thus maintain the stability of the power system. As an alternative to establishing battery energy storage systems, electric bus batteries can also be used as energy storage equipment by the power industry. This practice reduces power companies’ costs in constructing energy storage systems and helps bus operators, through engagement of their electric buses in the bus-to-grid (B2G) business model, to gain nonoperating income. This study conducted a cost-effectiveness analysis of electric buses under the B2G business model in comparison with conventional diesel buses in Taiwan. The results revealed that, in a user scenario, the net present value of 12 diesel buses was approximately 201.9 million NTD after considering the fixed costs, and variable costs. By contrast, the net present of 12 electric buses with subsidies from government was approximately 227.4 million NTD when bus operators purchased electric buses. If operators participate in B2G, their net present value can reach up to 277.4 million NTD. Hence, electric buses are cost effective in a user scenario. In a social scenario, the present value of the total cost of 12 conventional diesel buses was approximately 194.3 million NTD. Excluding the transfer payment of government subsidies, the net present value of the 12 electric buses is approximately 228.5 million NTD. If participating in B2G, its net present value can reach up to 235.9 million NTD. Therefore, adopting electric bus system is cost-effective.
