READ MORE1. Introduction. Nowadays, the energy generation systems are moving from the old concept of large-scale, centralized, power plants (Bell and Gill, 2018; Verbong et al., 2013) to the new model of distributed production systems (Gui and MacGill, 2018), also due to the wide adoption of Renewable Energy Sources (RES) (Greco et al., 2020;

READ MOREGreen pricing schemes have been set up in some IEA countries that offer consumers to pay more for renewable electricity. Thus, the increased cost of energy from renewable sources is borne by consumers voluntarily. In the case of voluntary actions, utilities or energy suppliers make a voluntary commitment to increase the use of
READ MOREIt can be seen below that the cost-optimal means of meeting the electricity demands as the renewable energy penetration is increased, is by first adding wind capacity. This is due to the fact that wind energy was the cheapest production method on all the islands except for Sumba. Increasing wind capacity was effective up to a critical point

The average weighted short-run marginal cost in 2040 is projected to be 7.8 USD/MWh, compared to 18.37 USD/MWh in 2020, due to the low operating costs of renewable energy plants and their high
READ MORETo achieve the decarbonisation of the electricity sector, a significant amount of renewable energy sources (RES) generation capacity is required to replace the phased-out fossil base load capacities. This process involves electrifying other energy sectors (e.g. transport), which will further increase the electricity demand to be covered by RES.
