nrel 80% renewable_electricity_integration_study
TRANSCRIPT
Portrayal of generation stack in 2050 for 4 days in summer peak load and 4 days in spring of lowest load showing how various generation types contribute, with 80% renewable generation.
Chart showing the increased cost of retail electricity due to integration of 80% renewables. The current study’s projection is the gray region that projects a $38 per Megawatt hour increase in 2050. Current national retail cost of electricity is approximately $120 per Megawatt hour.
This projection shows that the cost of integrating 80% renewable energy into the power grid is quite reasonable (and this is without major decreases in cost such as from improved photo-voltaic solar panels).
