Profitable or not two-tariff electricity meter

Twice a year, on schedule, the cost of electricity is growing. And probably every one of us more than once already thought about how to save to pay less. One option is to use a two-rate saving (trehtarifnogo) metering device. And, it would seem, here it is the solution to all problems, but in fact it is so? In this article I will discuss the pros and cons of switching to two-tariff meter and will make counting on the example of the region.

How we consume energy

According to statistics, a schedule of electricity consumption of an average family is as follows:

At night we sleep with you, so from 00:00 to 5:30 hours of electric energy consumption is minimal.

Then, we'll begin to wake up and get ready for work, so from 6:00 to 9:00 there is a morning peak consumption. Then, during the day the energy consumption is relatively flat and up to six in the evening does not change.

Then we come to work and begin to actively use electronic equipment in the home, and in the period from 18:30 to 23:00 there is an evening peak electricity consumption.

Based on these statistics, and dual-rate counters were designed to smooth out these peaks and evenly distribute the load during the day. Now let's look at the pros and cons of dual-rate meters.

Advantages and disadvantages of two-tariff metering devices

Let's start it with the advantages of such an instrument taking into account:

1. Saving your money (it is assumed that the payback period is 1.5-2 years).

2. Reduced and more uniform load distribution on the high-voltage equipment (which allows to save fuel and to increase the generating capacity resource). Of course, for ordinary people, plus questionable. And thereby reducing emissions of harmful components into the atmosphere during electricity generation, such as CHP.

For us is important only possible savings.

Now let's look at what the shortcomings can be identified in the dual-rate (trehtarifnyh) metering devices:

1. Tariffs established for such metering devices in all areas really profitable. One can observe a trend toward higher day rate base (single-rate) twice, and the night below baseline only 30%.

2. Using such an instrument taking into account demands of us a complete or partial restructuring of their traditional way of life.

So if such a counter is profitable

Now let's calculate whether the move is really so profitable in the two-tariff calculation and whether it is possible to reconstruct a normal life, to start saving on electricity.

As an example I will take rates of Stavropol Territory:

As you can see the difference between the rates is quite significant, let's calculate how much advantageous transition.

Thus, we assume the average family consumption of three (with a small child) around 300 kWh per month. In this case, the main burden falls on the day. So such a family spends on paying the bill for the light in a month: 300 * 4.48 = 1344 rubles.

Of the load, which can translate into real consumption this night: refrigerator (a priori it is constantly working, so then at night it will be cheaper) Dishwasher (partly because the children's dishes will still need to wash at once), washing machine (as children's clothes have to be washed in the afternoon, at night will only erase things adults).

So, it turns out that actually convert only 30% of the load, and it turns out that 200 kWh will go on the daily rate and the price is equal to 200 * 5.15 = 1030 rubles, and the night component equal to 100 * 3.58 = 358 rubles. A total expenses are equal to 1030 + 358 = 1388 rubles.

In this case, the economy is not at all. I hasten to say that the calculation is very rough and if you want to calculate the actual feasibility of the transition to the two-tariff metering device, on the record during the month how much your energy consumption is in the period from 7:00 to 23:00, and how much the consumption of 7:00 23:00.

Then multiply the kilowatts resulting tariffs is in your area and compare it with the usual fare.

So you know exactly whether it makes sense to move to two-tariff metering device. I hope the article will be useful to you.

Thanks for attention!
