The paper examines the compatibility of wind and solar energy resources with projections
of future electricity demand in Hungary. For such, we model the national electricity
system and estimate surplus generation. The model makes use of hourly distributions
of electricity demand and power generation. Simulations for the year 2033 (last scenario
year) suggest that 46–47% of the projected electricity consumption can be supplied
by wind turbines and solar PV technology with a surplus of less than 5% of yearly
consumption. A suitable capacity ratio of wind to solar PV and the management of electric
vehicle charging may reduce surplus electricity. It is shown by our EnergyPLAN model
that the solar PV capacity should be 1.1 times the wind power capacity which is a
huge contrast to the current situation where solar PV is 13 times the wind power capacity
in Hungary.
