在孟加拉国最近的国家可再生能源政策中，通过分散的可再生混合微型电网(HMG)实现离网、农村和偏远地区的电气化已成为优先事项。在考虑了广泛的社会经济因素的同时，开展了研究，以探索客户为这类HMG提供的电力的实际支付意愿(WTP)。2015年12月，在三个不同行政区的六个离网村庄，采用结构化问卷进行入户调查，收集受访者数据。目前煤油照明的成本和预期负荷需求在不同收入群体之间存在很大差异。平均每月照明成本在3.0美元到9.24美元之间，预计用电量为3.60千瓦时和33.76千瓦时。收入较高的家庭对煤油照明的平均满意度最低。然而，无论收入状况如何，更换HMG的平均意愿都很强。为此，采用了二分选择条件估值方法(CVM)。这里确定的最大水价(0.432美元/千瓦时)表明，可以采用可持续的电价模式来吸引该部门的私人投资。
Off-grid rural and remote area electrification through decentralized renewable hybrid mini-grids (HMG) has been prioritized in the recent national renewable energy policy of Bangladesh. Research was carried out to explore the actual customer willingness to pay (WTP) for the electricity to be supplied by such HMGs, while considering a wide spectrum of socioeconomic factors. Door to door household survey was conducted using structured questionnaire to collect respondent data in December 2015 from six off-grid villages under three different administrative districts. Wide variations in current cost of kerosene based lighting and expected load demand were observed among different income groups. Average monthly cost of lighting ranged between USD 3.0 to USD 9.24 and expected electricity usages as 3.60 kWh and 33.76 kWh. Families with higher income showed least mean satisfaction with kerosene lighting. However, strong mean willingness to switch HMG has been identified regardless of income status. The dichotomous choice contingent valuation method (CVM) was applied for this purpose. The maximum WPT value (USD 0.432/kWh) identified here indicates that a sustainable tariff model can be applied for attracting private investment in this sector.
