2026-2027 FINAL EXAM WITH QUESTIONS
AND CORECT DETAILED ANSWERS WITH
ALREADY GRADED A+
What are the main financial considerations in electricity generation?
ANSWER-Financial considerations include generation costs, transmission, distribution, and
administrative profits.
What percentage of consumer payments typically goes to electricity generation?
Approximately 60%.
How are electricity costs historically expressed?
In mills per kilowatt-hour, where 1,000 mills equal $1.
,What are the three main components of generation costs?
Capital, Operating and Maintenance (O&M), and Fuel costs.
What does capital cost in electricity generation include?
Land, equipment, construction, and interest.
What are the two types of O&M costs?
Fixed O&M costs ($/kW per yr) and Variable O&M costs (¢/kW·hr).
What is the relationship between plant size and costs according to the economy of scale?
As the plant size increases, costs decrease.
What is the significance of capital costs in relation to the plant's operating lifetime?
Capital costs must be distributed throughout the expected operating lifetime to find an annual
payment.
How are power plants classified based on capacity factor?
They are classified as Base load, Peak, and Intermediate plants.
What characterizes base load power plants?
,They operate 24/7 and have a high capacity factor.
What is a key feature of peak power plants?
They are used only as needed, typically during high demand periods.
What geological features are associated with geothermal power locations?
Cracks in the Earth's crust, known as rifts, often near tectonic plate boundaries.
What are the three classifications of geothermal sources?
Hydrothermal, Geopressured water, and Petr thermal.
What is the typical thermal efficiency of geothermal power?
Approximately 20%.
What are the two types of hydrothermal systems?
Vapor dominated and liquid dominated systems.
What is a flash steam geothermal plant?
, A plant where geothermal water is pumped under high pressure to the surface, where it flashes
into steam to drive a turbine.
What type of geothermal plant uses a binary cycle?
A plant that uses geothermal water to heat a secondary working fluid with a lower boiling point.
What is the typical temperature range for liquid dominated geothermal plants?
Between 225°F and 360°F.
What is the role of hot springs in geothermal locations?
They release geothermally heated groundwater.
What is the main advantage of binary cycle geothermal plants?
They produce no air emissions.
What is the typical depth range for drilling geothermal wells?
Between 3,000 to 9,000 feet.
What is the primary challenge associated with hydrothermal power plants?
Mineralization problems that can affect components over time.
