Using updated information from the EIA website for 2022: 1. Which technology has the longest lead time? The shortest lead time? 2. Which two technologies have the highest and next-to-highest Total Overnight Costs in 2022 as shown in the exhibit? 3. Which two technologies have the lowest and next-to-lowest Total Overnight Costs in 2022 as shown in the exhibit? 4. Heat rate is a measure of the amount of energy it takes to generate a kilowatt-hour. A higher high rate equates to lower efficiency. Using updated EIA information from 2022, which technology(ies) have the lowest high rate and which have the highest?
