Multi-zone counters

In view of the permanent increase in electricity prices is necessary to reflect on how to make good use of.

For example, setting a two-band meter apartment can significantly save energy and to pay half of the electricity used Kilowatt.

Consider the following example of economy, prices are as of the date of publication of this article.

Given:

Minimum one-time payments, a landmark:

Counter 2 zone - 1380 UAH.

Installation - 250 UAH.

Total one-time UAH = 1630 UAH

Assume the power consumption is 200 kW per month.

Of them:

1. 50 kW per month - a refrigerator and the light, the price = 50 * 0.714 kW (tariff, UAH) = 35.7 UAH
2. 50 kW per month - dishwasher, price = 50 * 0.714 kW (tariff, UAH) = 35.7 UAH
3. 50 kW per month - stiralka, price = 50 * 1.29 kW (tariff, UAH) = 64.5 UAH
4. 50 kW per month - multivarka, price = 50 * 1.29 kW (tariff, UAH) = 64.5 UAH

Total, without passing on the lower rate, in this case for the billing month to pay 200 UAH 40 kopecks.

We take into account that the reduced 2-fold rate applies to 23oo - 7oo

Given the setting and turn the work of home appliances during the term of the reduced rate (claims 2 - 4), it can be argued that the calculation of the electricity will be:

1. 50 kW per month - a refrigerator and a light - reducing the coefficient of payment = 8/24 = 0.33, the price = 50 * 0.714 kW (tariff, UAH) * (1 - 0.33) = 23.92 USD
2. 50 kW per month - dishwasher - 0.5, the price = 50 * 0.714 kW (tariff, UAH) * 0.5 = 17.85 USD
3. 50 kW per month - stiralka - 0.5, the price = 50 * 1.29 kW (tariff, UAH) * 0.5 = 32.25 USD
4. 50 kW per month - multivarka - 0.5, the price = 50 * 1.29 kW (tariff, UAH) * 0.5 = 32.25 USD

Total, with the transition to a reduced rate, in this case, you must pay 106 UAH 27 kopecks, net savings for the billing month - 94 UAH 13 kopeks.

Time of return on investment for replacement and installation of the two-band count = 1630 / 94.13 = 17.3 (months), up to about 1.5 years.

In a specific example, we have considered the obvious benefits of installing a 2-band energy meters, and, in the case of larger power consumption, or further increase the tariffs for its payback and profitability will increase.

Do the findings themselves.
