What are the main financial considerations in electricity generation? - (Correct Answer)-
Financial considerations include generation costs, transmission, distribution, and administrative
profits.
What percentage of consumer payments typically goes to electricity generation? - (Correct
Answer)-Approximately 60%.
How are electricity costs historically expressed? - (Correct Answer)-In mills per kilowatt-hour,
where 1,000 mills equal $1.
What are the three main components of generation costs? - (Correct Answer)-Capital, Operating
and Maintenance (O&M), and Fuel costs.
What does capital cost in electricity generation include? - (Correct Answer)-Land, equipment,
construction, and interest.
What are the two types of O&M costs? - (Correct Answer)-Fixed O&M costs ($/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? -
(Correct Answer)-As the plant size increases, costs decrease.
What is the significance of capital costs in relation to the plant's operating lifetime? - (Correct
Answer)-Capital costs must be distributed throughout the expected operating lifetime to find an
annual payment.
How are power plants classified based on capacity factor? - (Correct Answer)-They are classified
as Base load, Peak, and Intermediate plants.
, 2
What characterizes base load power plants? - (Correct Answer)-They operate 24/7 and have a
high capacity factor.
What is a key feature of peak power plants? - (Correct Answer)-They are used only as needed,
typically during high demand periods.
What geological features are associated with geothermal power locations? - (Correct Answer)-
Cracks in the Earth's crust, known as rifts, often near tectonic plate boundaries.
What are the three classifications of geothermal sources? - (Correct Answer)-Hydrothermal,
Geopressurized water, and Petrothermal.
What is the typical thermal efficiency of geothermal power? - (Correct Answer)-Approximately
20%.
What are the two types of hydrothermal systems? - (Correct Answer)-Vapor dominated and
liquid dominated systems.
What is a flash steam geothermal plant? - (Correct Answer)-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? - (Correct Answer)-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? - (Correct
Answer)-Between 225°F and 360°F.
What is the role of hot springs in geothermal locations? - (Correct Answer)-They release
geothermally heated groundwater.
, 3
What is the main advantage of binary cycle geothermal plants? - (Correct Answer)-They produce
no air emissions.
What is the typical depth range for drilling geothermal wells? - (Correct Answer)-Between 3,000
to 9,000 feet.
What is the primary challenge associated with hydrothermal power plants? - (Correct Answer)-
Mineralization problems that can affect components over time.
What is the purpose of drilling new wells in hydrothermal systems? - (Correct Answer)-To
maintain production after existing wells have been used for a few years.
What is the significance of the Pacific 'Ring of Fire' in geothermal energy? - (Correct Answer)-It
is a region with significant geothermal activity due to tectonic plate movements.
What are the conditions for Geopressurized Water? - (Correct Answer)-Approximately 350°F
and 16,000 psi.
Where is Geopressurized Water typically found? - (Correct Answer)-Trapped in deep
underground aquifers.
What is one of the uses of Geopressurized Water? - (Correct Answer)-Extracting and burning the
methane content within the produced hot water (brine).
What is Petrothermal also known as? - (Correct Answer)-Hot Dry Rock (HDR).
What is the temperature range for Petrothermal systems? - (Correct Answer)-300-550°F.
