Hong Kong's electric market is not a 100% elastic demand.
Actually your question is about what is the determiner of the price elasticity of demand?
The following factors determine price elastic demand:
1. Availability of close substitutes ( No substitutes )
2. Necessities or luxuries ( necessities )
3. Definition of the market ( good )
4. share of expenditure on the good ( have no data supports if it's high, it can be elastic, otherwise can be inelastic)
5. Habit forming ( no comment )
6. Product durability ( must maintain )
7. The length of time involved ( have no data supports if it's long, elastic, short inelastic)
