Time-of-Day Tariff Monitoring
Same units, cheaper hours.
A Time-of-Day (ToD) tariff, also called Time-of-Use, charges different electricity rates by hour: a premium in peak windows, standard rates in normal hours and a discount in off-peak and solar hours. The Electricity (Rights of Consumers) Amendment Rules, 2023 made ToD mandatory for C&I consumers above 10 kW maximum demand from 1 April 2024. Titan Class 0.5S meters record energy and maximum demand across up to eight ToD zones.
Under a Time-of-Day tariff, when you use energy matters as much as how much. Titan Class 0.5S meters split your consumption and demand across up to eight ToD windows, so you can shift flexible load out of the expensive peak hours, use off-peak and solar-hour rebates, and keep demand peaks out of the priciest window.
What Titan tracks
- →Consumption & demand across up to 8 ToD zones
- →kWh and rupees in peak / normal / off-peak
- →Alerts on avoidable load in peak windows
- →Demand peaks by time-of-day
- →Solar-hour vs grid-hour consumption
Why the Hour of the Day Now Matters
A Time-of-Day tariff turns timing into money — in both directions.
Peak-Hour Energy Costs More
Under a Time-of-Day (ToD) tariff, energy in peak windows is charged at a premium — for C&I consumers, at least 1.20× the normal rate under the 2023 ToD rules. Run the same load at the wrong hour and it simply costs more.
Off-Peak & Solar-Hour Rebates
The flip side: ToD tariffs discount solar-hour consumption — at least 20% below the normal rate, during solar hours set by your State Commission — and many also discount night off-peak hours. Shifting flexible loads into those windows lowers the bill, but only if you know when your load actually runs.
Now Mandated for C&I Consumers
The Electricity (Rights of Consumers) Amendment Rules, 2023 (Ministry of Power) require ToD tariffs for commercial and industrial consumers with maximum demand above 10 kW from no later than 1 April 2024, and for most other consumers (except agriculture) from 1 April 2025. The exact windows and rates are set in your State Commission's tariff order.
Peak Demand in Peak Windows
Under the 2023 rules the ToD differential applies to the energy charge; demand is billed separately on your month's maximum demand. The same busy hours often drive both — so a heavy load running in the peak window costs you at the peak energy rate and can also set your billed maximum demand.
What Titan Monitors
You can only shift load out of peak hours if you can see which hours your load runs in.
Up to 8 ToD / Tariff Zones
Titan tracks consumption and demand across up to eight configurable Time-of-Day zones on-device — matching your utility's exact peak, normal, off-peak and solar windows.
Load Split by Window
See how much energy and demand falls in each window, in kWh and in rupees. The picture that tells you which loads to shift and how much you'd save.
Peak-Window Alerts
Get alerted when avoidable load is running in a peak window, or when demand is climbing during peak hours — in time to defer it to a cheaper window.
Solar-Hour Optimisation
Line up your ToD windows with on-site solar generation and see whether flexible loads are actually running during the cheap, self-generated hours.
