Multi-tariff (TOU) Energy Meters Manufacturer.

High-performance smart metering infrastructure for global utility networks and sustainable energy grids.

Narrative

Technical Innovation & Quality Heritage

YTL’s Multi-tariff (TOU) Energy Meters are powerful tools for utilities to implement demand-side management. As an expert manufacturer, Zhejiang Yongtailong has equipped these meters with high-precision, temperature-compensated real-time clocks (RTC) to support complex Time-of-Use pricing. These meters can be programmed with up to 8 different tariff periods (e.g., Peak, Off-Peak, Shoulder), allowing utilities to incentivize consumers to shift their energy use to low-demand periods. This not only helps balance the grid load but also allows users to significantly reduce their bills by running heavy appliances during "valley" periods. With detailed load profiling and historical data storage, our TOU meters provide the transparency needed for modern, flexible electricity markets.

Product Application

  • Industrial Peak Shaving
  • Residential Smart Pricing
  • EV Charging Infrastructure

Industrial Peak Shaving

For large factories, electricity prices vary drastically throughout the day. Using YTL’s TOU meters, facility managers can identify "Peak" periods when electricity is most expensive. By rescheduling energy-intensive processes—like heavy smelting or industrial cooling—to "Off-Peak" hours, the factory can save thousands of dollars monthly in energy costs. The meter's Maximum Demand feature also helps the facility stay within its contracted power limits, avoiding heavy penalties from the utility and improving the overall efficiency of the industrial plant.

Residential Smart Pricing

Utilities use these meters to offer flexible plans to residential customers, such as lower rates on weekends or during the night. The TOU meter provides the homeowner with a clear breakdown of when they use the most energy. This transparency encourages the use of smart timers for dishwashers and laundry machines to operate during cheaper "Valley" hours. Over time, this shifts the neighborhood's load profile, reducing the need for the utility to fire up expensive peaker plants and lowering the carbon footprint of the community.

EV Charging Infrastructure

In public and private EV charging stations, TOU meters are critical for fair pricing. They allow charging operators to set higher prices during daytime peaks and offer "overnight charging" discounts to EV owners. The meter’s high-precision clock ensures that the switch between price tiers happens exactly on the second. This helps manage the local transformer load by preventing all EVs from charging at the same time, ensuring a sustainable and cost-effective rollout of electric vehicle infrastructure.

Product Advantages

Precision Timekeeping

Features an independent, battery-backed RTC that stays accurate for over 10 years, ensuring that billing transitions between price tiers are always fair and synchronized.

Flexible Tariff Configuration

Fully programmable to match any global utility's pricing structure, including complex seasonal changes, weekend rates, and special public holiday tariffs.

Historical Data Audit

Stores an extensive record of consumption by tariff and peak demand for the past year, providing a robust audit trail for resolving any billing disputes.

Frequently Asked Questions

  • Q: What happens to the time if the power goes out?

    A: The meter has a high-quality internal lithium battery that keeps the clock running accurately even during extended power outages.

  • Q: Can the utility change my rates remotely?

    A: Yes, if the meter is part of an AMI network, the utility can push a new tariff table to the meter remotely without a technician visiting your home.

  • Q: How many time zones can I set?

    A: Our TOU meters typically support up to 8 or 12 different time periods within a single 24-hour cycle to cover peak, shoulder, and valley rates.

  • Q: Does it show which tariff is currently active?

    A: Yes, the LCD will display an indicator (like T1, T2, etc.) so you can see at a glance if you are currently being billed at the peak or off-peak rate.

  • Q: Can it track my peak power usage?

    A: Yes, it records the Maximum Demand (MD) in kW and the exact time it occurred, which is vital for commercial customers on demand-based billing.
