Implementation of maximum demand charge is a possible solution to better reflect the cost of generating and delivering electricity. However, this implementation leads to additional charge in the electricity bill and would effect on the electricity affordability among the residential customers. As a preliminary study on the issue related to electricity affordability and willingness to pay for maximum demand charge, this paper uses survey data collected from 411 residential electricity customers in Malaysia and descriptive analysis. Findings from this study indicates most of the respondents do not face electricity unaffordability problem and seem to be willing to pay for the maximum demand charge. � BEIESP.

Renewable Energy studies are gaining more interest by involved parties such as energy producer as well as research community. However, there are still limited number of studies in particular concerning instrument to measure public participation towards Renewable Energy (RE) development in Malaysia. The instrument for assessing public participation seem to require some extent of revalidation. Thus, the purpose of this paper is to validate the factor structure of public participation instrument that measured by willingness to pay level and it determinants. The questions of this developed scale were derived from previous published quantitative study. Validity and reliability of the instruments were assessed with Exploratory Factor Analysis (EFA) and Cronbach�Alpha respectively. Four hundred and five respondents had participated in this study. Results from this study revealed that the originally validated form of every factor structure, i.e. Willingness to pay (WTP), Awareness on RE (ARE), Knowledge on RE (KRE), Willingness to adopt RE technology (WTA) and Attitude towards RE usage (AURE) and Environmental concern (EC) had performed as per previous literatures within this research context. Furthermore, all the revised factors had a good reliability with the Cronbach�s Alpha value well above 0.70 of threshold. Therefore, a total of 45-items revised in public participation toward RE measurement might be better suited for use within the selected population. This information provides preliminary evidence that the public participation towards RE instrument is a reliable and a valid measure that can be used to provide the data regarding Renewable Energy (RE) development in Malaysia. However, in order to cross validate, in future study can be conducted by engaging other location to cater different public opinion. � BEIESP.
