What does the term 'distributed generation' mean in BGE's operational context?
Answer: Small-scale power sources located close to the point of use, such as rooftop solar
Distributed generation refers to small energy sources like rooftop solar or backup generators located at or near customer facilities.
Which phenomenon, caused by inductive and capacitive loads, reduces the efficiency of BGE's distribution system if left uncorrected?
Answer: Poor power factor
Poor power factor means more current must flow to deliver the same real power, increasing line losses and reducing system efficiency.
BGE's smart grid investments include Advanced Metering Infrastructure (AMI). What key capability do AMI meters provide?
Answer: They allow two-way communication of usage data between customers and BGE
AMI meters transmit interval usage data to BGE and can receive signals for programs like time-of-use pricing or remote disconnect.
What is the approximate voltage level used on BGE's high-voltage transmission lines that connect major substations?
Answer: 115 kV to 500 kV
BGE operates transmission infrastructure at voltage levels ranging from 115 kV to 500 kV for long-distance bulk power transfer.
Which condition triggers a 'brownout' in BGE's service area, as distinct from a full blackout?
Answer: A sustained undervoltage condition where voltage drops but service continues at reduced levels
A brownout is a deliberate or unintentional reduction in voltage to manage grid stress, unlike a blackout which is total power loss.
In BGE's generation mix procurement through PJM auctions, what is the primary mechanism for ensuring long-term capacity adequacy?
Answer: The PJM Capacity Market (RPM auction)
PJM's Reliability Pricing Model (RPM) capacity auction commits resources years ahead to guarantee sufficient generation exists to meet future peak demand.
What safety hazard is created when a downed BGE power line energizes the surrounding ground, creating a voltage gradient?
Answer: Step potential, which can electrocute anyone walking near the line
Step potential occurs when current flows through the ground from a downed energized conductor, creating dangerous voltage differences between footsteps.
