The most distinctive feature of an ESCO is that they do not require customers to make large initial outlays for equipment expenses, but can instead pay on an installment basis, drawing on the savings created by reduced power consumption. Customers thus are not tempt-ed to refuse because of an unwillingness to spend.
ESCO 最大的特色在於客戶不必先付龐大的設備費用，而是以日後節省下來的能源費用分期攤還，讓客戶不會因為心疼花錢而拒絕。
