越来越多的人承认，可再生能源微型电网将在普及电力方面发挥不可或缺的作用，因为它们现在被认为是远离国家电网的地点电气化的最低成本选择。然而，迷你电网的部署步伐因多重障碍而变得缓慢。这篇论文研究了加纳的这些障碍，因为今天有相当大一部分人口无法用上电，必须通过微型电网供电。通过文献回顾和实地研究相结合的方法，确定并验证了22个障碍，将其划分为政治、经济、技术、社会和环境类别，并最终使用层次分析(AHP)方法进行排名。分类结果显示，政治障碍是最重要的障碍(44.3%)，环境障碍最小(6.4%)。总体结果将前十大障碍集中在三个主要障碍类别：政治障碍(5)、经济障碍(3)和技术障碍(2)，这三个类别占集体障碍权重的70%。获得融资的重要性最高，为11.7%，而有限的支付能力被赋予3.88%的重要性。这篇论文认为，严重缺乏资金，再加上一项政策，加剧了这一问题，这项政策强加了无法承受的补贴，限制了商业模式创新，最不支持生产性用途，并驱散了私人资本投资，阻碍了加纳加快部署迷你电网，以便及时普及电力。因此，需要对当前政策进行修改。
There is growing acceptance that renewable energy mini-grids will play an integral role in the attainment of universal access to electricity as they are now considered to be least cost option for the electrification of locations far from the national grid. Yet, the pace of mini-grids deployment is tapered by multiple obstacles. The paper examined these barriers for Ghana, since a sizable proportion of the population without access to electricity today, will have to be electrified through mini-grids. By coupling literature reviews with field research, twenty-two barriers were identified and validated, dimensioned into political, economic, technical, social and environmental categories, and eventually ranked using the analytic hierarchy process (AHP) method. The category results ranked political barriers as the most important obstacles (44.3%) and environmental as the least (6.4%). The overall results concentrate the top ten barriers around three main barrier categories; Political (5) Economic (3) and Technical (2), which makes up 70% of the collective barrier weight. Access to finance is accorded the greatest share of importance of 11.7% while limited paying capacity is assigned 3.88%. The paper argues that severe lack of funding, exacerbated by a policy that imposes unbearable subsidies, limits business model innovation, least support productive uses and dispels private capital investment, impedes accelerated deployment of mini-grids for timely universal access to electricity in Ghana. Modifications to the current policy are therefore required.
