What is demand response and how does it support grid reliability?

• A. Consumers adjust or reduce electricity use in response to price signals or incentives; helps shave peak demand, improves reliability, and reduces the need for peaking generation.
• B. Demand response involves increasing consumption during peak hours to maximize revenue.
• C. Demand response creates new generation capacity during outages.
• D. It only applies to industrial customers and does not affect reliability.

Answer: (A)

Demand response is a program where people and businesses reduce or shift their electricity use in response to price signals or incentives. By cutting back during times of high demand or tight supply, the overall load on the grid is lowered, which helps shave peak demand and reduces the need to run expensive or fast-start generation. This keeps the system more balanced and improves reliability because grid operators have a bigger margin to manage contingencies, maintain voltage and frequency, and avoid outages. It can be delivered automatically through smart controls or manually by consumers, and it benefits a wide range of customers, not just large industrial users.
