It is expected that the implementation of MEPS will also help to address the challenges of unreliability of electricity supply and facilitate the desired energy-efficient appliance market transformation. The MEPS currently covers the three most energy-consuming electrical products in households (lighting, refrigerators, and air conditioners). This research relied on data collected from the survey of 384 households in the case study area of Enugu to study the policy impacts of the current MEPS and identify the potential for its improvement. The research also, empirically, investigated policy and institutional barriers against appliance energy efficiency improvement in the country. Three different policy scenarios were conceptualized to model the policy impacts of current MEPS: a scenario assuming no MEPS or a business-as-usual (BAU) scenario, a policy scenario (PS) that considers the current MEPS, and an aggressive policy scenario (APS) that assumes the scaling up of the current MEPS to more stringent levels. The policy analysis modeling system (PAMS) was adopted to study the impacts of MEPS considering a policy implementation period of 2019 through 2030. The United Nations' integrated policy framework was also adopted as evaluation criteria to identify policy gaps in the existing policy measures and the identification of possible policy overlaps was conducted using content analysis. Based on the results, the implementation of the current standards would reduce annual residential electricity demand in the surveyed households by 37\% compared to BAU. National-level policy impacts show that the implementation of more stringent MEPS would contribute about 11.3\% of the national emissions reduction target reached in Nigeria's NDC. The research also finds out that key policy instruments (such as financial incentives) are still in their planning stages. Furthermore, the result from the content analysis reveals that the assigned institutional roles for the advancement of end-use energy efficiency are in some cases, not based on the statutory mandates of the respective institutions which create room for possible overlaps. To close the existing energy efficiency gaps and achieve effective energy-efficient appliance market transformation, the research underscores the need for a large-scale appliance market assessment to understand current baseline efficiency levels which will guide future policy designs and ensure that MEPS remain effective. The research also recommends key possible frameworks that can guide the design and implementation of financial incentive instruments to make energy-efficient investments more attractive.}, subject = {Mindeststandards f{\"u}r die Gesamtenergieeffizienz; Auswirkungen der Politik; Nationally Determined Contribution; Pariser Abkommen; Haushaltsger{\"a}te; Minimum Energy Performance Standards; Policy impacts; Nationally Determined Contribution; Paris Agreement; Appliances; Nigeria; Klimaabkommen von Paris; Energieeffizienz; Emissionsverringerung; Elektrisches Haushaltsger{\"a}t; Elektrizit{\"a}tsversorgung}, language = {en} }
