Renewable Energy & Sustainability Flashcards

What is the purpose of BGE's Electric Vehicle (EV) charging infrastructure incentive programs?

Answer: To encourage customers and businesses to install EV chargers by offsetting installation costs

BGE's EV programs offer rebates and incentives to customers and businesses to install Level 2 and DC fast chargers, supporting broader EV adoption in the service territory.

What is 'curtailment' in the context of renewable energy grid management?

Answer: Intentionally reducing renewable generation output when supply exceeds grid demand

Curtailment occurs when grid operators reduce output from renewable sources like wind or solar because the grid cannot absorb all the power being generated at that moment.

Maryland's 'Community Solar' program primarily benefits which group of electricity customers?

Answer: Customers who cannot install rooftop solar due to renting, shading, or roof limitations

Community solar allows renters, condo owners, and others who cannot install rooftop panels to subscribe to a shared off-site solar array and receive bill credits.

What is the main advantage of 'behind-the-meter' battery storage installed at a customer's home or business?

Answer: It stores self-generated or off-peak grid electricity for use during outages or high-rate periods

Behind-the-meter storage lets customers use stored energy during outages or peak-rate periods, reducing grid dependence and maximizing the value of their solar or off-peak electricity.

Which aspect of BGE's sustainability strategy involves planting trees to offset carbon emissions and improve urban environments?

Answer: Reforestation and urban forestry programs

BGE participates in reforestation and urban forestry programs that plant trees to sequester carbon, reduce urban heat islands, and improve air quality in the service territory.

What does the 'duck curve' phenomenon in solar-heavy grids illustrate about grid management challenges?

Answer: A demand curve that dips midday when solar peaks and then sharply rises in the evening when solar drops off

The duck curve shows how net electricity demand drops midday when solar generation peaks but then surges rapidly in the evening, requiring fast-ramping backup resources to fill the gap.

How does BGE's smart thermostat program contribute to sustainability goals?

Answer: It enables automated adjustment of home temperatures during peak demand events, reducing grid stress

Smart thermostats enrolled in BGE programs can be remotely adjusted during peak demand events to reduce energy consumption, lowering both grid strain and customer bills.
