Energy Generation & Distribution Flashcards

Which type of power plant does BGE primarily rely on for baseload electricity generation in the PJM Interconnection?

Answer: Nuclear power plants

Nuclear power plants provide consistent baseload generation in the BGE service territory through PJM.

What is the role of a substation transformer in BGE's distribution system?

Answer: To step voltage down for safe delivery to homes and businesses

Substation transformers reduce high transmission voltages to lower distribution voltages suitable for end-use customers.

In electricity distribution, what does the term 'radial feeder' describe?

Answer: A feeder that supplies power in one direction from a single source

A radial feeder distributes power in a single path from substation to customers without a return loop.

Which fuel source is used in BGE's service territory peaker plants that activate during high-demand periods?

Answer: Natural gas

Natural gas peaker plants can start quickly and are used to meet demand spikes in the BGE region.

What is the standard distribution voltage BGE uses to deliver electricity along neighborhood lines before final step-down?

Answer: 13,200 volts

BGE distributes electricity at approximately 13,200 volts (13.2 kV) along primary distribution lines before pad-mount or pole transformers reduce it further.

Which organization operates the regional transmission grid that BGE participates in for wholesale electricity dispatch?

Answer: PJM Interconnection

PJM Interconnection manages the bulk power system and electricity markets across the mid-Atlantic region including BGE's territory.

What is 'demand response' as it applies to BGE's grid management strategy?

Answer: Incentivizing customers to reduce usage during peak grid stress periods

Demand response programs pay or credit customers who voluntarily cut electricity use during peak periods, reducing grid strain.
