背景缺乏电力供应的挑战，特别是在尼日利亚的农村地区，由于缺乏令人信服的电气化计划而进一步加剧。一个相当合理的电气化计划应该能够模拟将要采用的成本最低的电气化技术，并对给定时期内所需的投资作出估计。联合国宣布2012年为“人人享有可持续能源国际年”，强调了此类研究和创新的重要性，以吸引各种来源的资金用于可持续电气化项目。方法借助空间电力规划模型，称为“网络规划师”（NP Planner），本研究确定了适当的最低成本电气化供应模式（电网、微型电网和/或离网），并提供了到2030年实现尼日利亚普遍能源接入的成本估计。结果这项研究的结果表明，到17年规划期结束时，到2013年至2030年，98%目前未通电的社区将可用于电网扩展，而只有2%将与微型电网兼容。到2030年，为总共2850万户家庭（1.25亿人）提供电力，估计需要345亿美元的投资。进行了分析的36个州的尼日利亚以及整个国家，使用的数据从774个地方政府地区（LGAs）的尼日利亚.ConclusionsThis文件提供了尼日利亚农村电气化机构（NREA）制定电气化计划的基础，以及涉及所有利益相关者在开展直接调查，以产生一个数据库，农村电气化状况在尼日利亚。
BackgroundThe challenge of lack of access to electricity especially in the rural areas of Nigeria is further compounded by the lack of cogent electrification plans. A fairly reasonable electrification plan should be able to model least-cost electrification technologies to be employed and give an estimate of investments required over a given period of time. The 2012 United Nation’s declaration of ‘International Year of Sustainable Energy for All’ highlights the importance of such studies and innovations, towards attracting funds from various sources for sustainable electrification projects.MethodsWith the aid of a spatial electricity planning model called the ‘Network Planner (NP)’, this study identifies the appropriate least-cost electrification supply mode (grid, mini-grid and/or off-grid) and provides cost estimates for achieving universal energy access in Nigeria by 2030.ResultsResults from this research show that by the end of the 17-year planning period (2013 to 2030), 98% of currently unelectrified communities will be viable for grid expansion, while only 2% will be mini-grid compatible. An estimated total cost of US$34.5 billion investment is required to provide electricity access to a total number of 28.5 million households (125 million people) by 2030. The analysis was carried out for the 36 states of Nigeria as well as the entire country, using data from the 774 local government areas (LGAs) of Nigeria.ConclusionsThis paper provides the foundation for the Nigerian Rural Electrification Agency (NREA) to develop an electrification plan as well as involve all stakeholders in carrying out direct surveys towards generating a database for rural electrification status in Nigeria.
