Demand for electricity in Nigeria: Some empirical findings

This paper presents the findings from an econometric model of Nigerian electricity demand. Electricity consumers are partitioned into three classes-namely. Residential, Commercial and Industrial. It shows that over the last two decades there has been tremendous increase in both the supply and demand for electric energy. Although supply has increased, it has not been able to keep pace with demand. Various explanatory variables that determine changes in demand are analysed for each of the three consuming sectors. The findings are as follows.(i) Per capital income, previous level of electricity consumption and urbanization are the most significant explanatory variables for the Residential sector's electricity consumption. The short and long-run income elasticities are found to be below unity, while whose of urbanization are above unity. The average price of electricity, though rightly signed, was found to be insignificant.(ii) As regards the commercial sector, the significant explanatory variables were previous level of electricity consumption, income, average price of electricity and urbanization. Urbanization was, however, found to be the most sensitive variable in respect to changes in the sector's electricity demand.(iii) Previous level of industrial electricity consumption and degree of urbanization were the main explanatory variables for changes in the Industrial sector's demand for electricity. Industrial output and income were not found to be significant variables in explaining changes in the Industrial sector's demand for electricity.

Determinants of price mark‐up tolerance for green electricity – lessons for environmental marketing strategies from a study of residential electricity customers in Germany

This paper develops hypotheses on the effects of various attitudinal and perceptual variables as well as socio‐demographic characteristics of residential electricity customers on an individual's willingness to pay a mark‐up for electricity generated from renewable energy sources compared with the price due for electricity from conventional sources. The hypotheses are tested with data from a standardized telephone survey of 238 household electricity consumers in Germany. 53.4% of the participants are willing to pay a mark‐up for green electricity. 26.1% report a price tolerance equal to a 5–10% increase in their current electricity bill. Binary logistic and ordinal regression analyses indicate that price tolerance for green electricity is particularly influenced by attitudes (1) towards environmental issues and (2) towards one's current power supplier, (3) perceptions of the evaluation of green energy by an individual's social reference groups, (4) household size and (5) current electricity bill level. The findings are used to derive suggestions for energy related informational activities of public institutions, green marketing strategies of energy companies and future consumer research regarding demand for pro‐environmental goods.

Malmquist productivity index for multi-output producers: An application to electricity generation plants

Different types of plants are used to generate electricity in the US: single-, multi-, and mixed-electricity plants. In this paper, we question the best type/design of plants for both renewable and non-renewable electricity. To do so, we suggest a new index that takes the form of a Malmquist productivity index. The specificity of our new index is that it offers the option to investigate the performances and the causes of the performance changes for each type of electricity separately; this is not possible when relying on more standard indexes. Moreover, our new index takes the links between the inputs and the outputs into account, and is nonparametric in nature. Using our index, we study the performances of more than 5000 plants for the period 2000–2012. Our findings reveal that single-electricity plants perform better for renewable electricity, while multi-electricity plants perform better for non-renewable electricity. This is coherent with the decreasing importance of multi-electricity plants in the US, and the increasing importance of single-electricity plants producing renewable electricity. Furthermore, our results do not suggest that combining renewable and non-renewable electricity generations within a plant improves the performance of the plants. Finally, we demonstrate that the reasons for the changes in performance are different for each type of electricity and plant.
