This paper presents the results of calculation and mapping of the commercial potential of wind and solar energy source and preliminary assessment of the ability to absorb renewable energy of the power transmission grid in the 5 provinces of the Central Highlands. The research results show that the total area of land that can be developed for wind and solar power plants is 106,869ha and 29,519ha, respectively, with a total capacity of 5.1GW and 24.6GWp respectively. The Central Highlands power transmission grid infrastructure as planned by 2030 is capable of absorbing 3,467 MW compared to 29,693 MW of commercial renewable energy potential, accounting for about 12%.
