a) What is the total variable cost of generation for each of the 3 technologies (coal, gas, and solar) in S/MWh? b) What is the total operating cost of generation for each of the 3 technologies on an annual basis for each unit of installed capacity ($/W-yr)? c) What is the LCOE (levelized cost of electricity) in S/MWh for each of the 3 generating technologies (coal, gas, solar)? Questions: 30 year lifetime for each technology (at the end of which let us assume the plant is worthless) 8% cost of capital $10 per ton cost of carbon emissions 15% capacity factor for solar 85% capacity factor for coal and gas Assumptions: 8,760 hours per year For discounting purposes, assume revenue and costs from each year of operation are incurred at the end of the year overnight capital cost (S/w) Variable O&M ($/MWh) (S/MMBTU) (BTU/kWh) (tons/MWh) CO2 emissions Fixed O&M Fuel cost Heat rate Technology type coal (dual unit advanced PC) ($/kW-yr) 2.3 30 15 25 8800 as (advanced combined cycle solar Pv 3.3 6430 2 0
