2020 Scenario

The generation of the demand profiles for the 2020 scenario were based on literature reviews and government policies which aim to reduce demand by increasing the efficiency of electrical appliances and increasing insulation levels of buildings [1,2,3].

The following assumptions where made for the creation of the 2020 scenario:

- It is assumed that from 2012 to 2020, 10% more of the community people will work at home

- The thermal demand, according to government statistics, would be reduced by ~20 % due to improvements in insulation for buildings.

- Misc includes: Microwaves, hi-fis, kettles, hairdryers, toasters, irons, vacuum cleaners, tumble dryers, printers…

- Some of the appliances efficiency improvements are shown in the table shown below [4].
