Elevator Power Consumption – Types, Standby Power, and Electricity Bills
Lifts, also known as elevators, play a crucial role in modern buildings, providing vertical transportation convenience. Understanding the power consumption of lifts is important for managing energy usage and estimating electricity costs. In this article, we will explore the power consumption of different types of elevators, the power consumed when in standby mode, and compare the monthly electricity consumption of various lift brands.
Types of Lifts and Power Consumption
The power consumption of a lift depends on its capacity and design. Let’s compare the power consumption of different lift types based on their passenger capacity:
- 4 Passenger Lift: A 4 passenger lift typically consumes around 2,500 to 4,000 watts of power during operation, depending on factors such as motor efficiency and design. The power consumption per hour would be approximately 2.5 to 4 units.
- 6 Passenger Lift: A 6 passenger lift usually consumes around 3,000 to 5,000 watts of power while in operation, resulting in a power consumption of approximately 3 to 5 units per hour.
- 8 Passenger Lift: An 8 passenger lift generally consumes around 4,000 to 6,000 watts of power during operation, equating to a power consumption of approximately 4 to 6 units per hour.
Standby Power Consumption of Elevator
Lifts also consume a certain amount of power even when not in use, commonly referred to as standby power. Standby power is required for functions such as keeping the lift ready for immediate operation, maintaining lighting and ventilation, and powering control systems.
The standby power consumption of a lift can range from 200 to 500 watts, depending on the lift’s design and features. This corresponds to a power consumption of approximately 0.2 to 0.5 units per hour when the lift is in standby mode.

Monthly Elevator Power Consumption by Brands
Different lift brands may have variations in power consumption based on their design, efficiency, and technological advancements. Let’s compare the estimated monthly electricity consumption of popular lift brands available in the market.
- Otis: Otis lifts are known for their reliability and energy efficiency. The monthly electricity consumption of Otis lifts can vary based on factors such as lift type and capacity. On average, an Otis lift may consume around 3,000 to 6,000 units per month, depending on usage patterns and lift specifications.
- Schindler: Schindler lifts are designed with a focus on energy efficiency and sustainability. The monthly electricity consumption of Schindler lifts can range from 2,500 to 5,500 units, considering factors such as lift type, capacity, and usage.
- KONE: KONE is renowned for its innovative lift solutions with a strong emphasis on energy efficiency. The monthly electricity consumption of KONE lifts may vary from 2,000 to 5,000 units, depending on lift type, capacity, and usage patterns.
It’s important to note that the power consumption mentioned for different lift types and brands are approximate values and can vary based on specific models, lift configurations, and operational factors.
Power Consumption By Example
Example 1: Assuming an electricity rate of Rs. 6 per unit, if a domestic elevator is used moderately for an average of 20 hours per week, the monthly power consumption would be approximately 80 to 120 units (4 to 6 units per hour * 20 hours * 4.33 weeks). Consequently, the estimated monthly electricity bill would range from Rs. 480 to Rs. 720 (80 units * Rs. 6 to 120 units * Rs. 6).
Example 2: Considering the same electricity rate and assuming slightly higher usage, if the domestic elevator is used moderately for an average of 25 hours per week, the monthly power consumption would be around 100 to 150 units (4 to 6 units per hour * 25 hours * 4.33 weeks). This would result in an estimated monthly electricity bill ranging from Rs. 600 to Rs. 900 (100 units * Rs. 6 to 150 units * Rs. 6).
Example 3: For a domestic elevator with even higher usage, assuming an average of 30 hours per week, the monthly power consumption would be approximately 120 to 180 units (4 to 6 units per hour * 30 hours * 4.33 weeks). Hence, the estimated monthly electricity bill would range from Rs. 720 to Rs. 1,080 (120 units * Rs. 6 to 180 units * Rs. 6).
