What does 'spinning reserve' mean in the context of BGE's grid operations?
Answer: Online generators running below full capacity ready to increase output instantly
Spinning reserve refers to capacity from already-running generators that can be ramped up immediately to cover sudden load increases or generator failures.
BGE's underground distribution cables are most commonly insulated with which material?
Answer: Cross-linked polyethylene (XLPE)
Modern underground distribution cables in BGE's network use cross-linked polyethylene insulation for durability and moisture resistance.
What function does a capacitor bank serve on BGE's distribution feeder?
Answer: It improves power factor and reduces reactive power losses on the line
Capacitor banks supply reactive power locally, correcting power factor and reducing line losses on distribution feeders.
Which measurement unit does BGE use when reporting annual electricity sales to large commercial customers?
Answer: Megawatt-hours (MWh)
Megawatt-hours (MWh) measure energy consumed over time and are standard for billing large commercial and industrial accounts.
In BGE's territory, which entity sets the retail electricity distribution rates that BGE charges customers?
Answer: The Maryland Public Service Commission (PSC)
The Maryland Public Service Commission regulates BGE's distribution rates through formal rate case proceedings.
What is the purpose of automatic reclosers on BGE's overhead distribution lines?
Answer: To briefly interrupt and reclose the circuit to clear temporary faults without a sustained outage
Reclosers interrupt the circuit for a brief period after a fault; if the fault was temporary (like a tree branch), the line restores automatically.
When BGE energizes a new residential subdivision, what is the typical final step-down voltage delivered to each home?
Answer: 240/120 volts split-phase
Residential service in the U.S. is delivered as 240/120V split-phase, providing both 120V for outlets and 240V for large appliances.
