Increasing Apartment Connection Power for 7.4kW Induction, 2.2kW Appliances: 14-15kW vs 16-17kW

Hello,
I have read a lot of topics regarding connection reporting, but I still have no answers. I would like to increase the connection power in the apartment. The devices I plan in the apartment are:
- 7.4 kW (2 phase) induction
- washing machine 2,2kW
- 2kW washing dryer
- 2kW dishwasher
- 2,2kW kettle
- 3.2 kW oven

I would like to ask about what connection power I should report to the EE at 3 phases.
From the formula "P = ?3 o U o I o cos ?" by replacing something ? = 0.95, the total current goes to me:

Ib = 17000 / (1.74 * 400 * 0.95) = 25.71A

Will the connection power of 14-15kW and 3x25A pre-meter protection be enough, should I order 16-17kW and then 3x32A protection?
In the power plant for my apartment, the cost of increasing power was calculated for:
price = number of additional kW * coefficient of simultaneity (0.213) * 76.54 PLN gross. It gives about PLN 16 for 1kW. with an additional 10kW, it's about PLN 160.

Hello.

Maybe I do not know, but I do not like the one-off fee for an extra kW.
Is it really 16 PLN?

PS. The connection power of 14-15 kW and 3x25A pre-meter protection is enough

Yes, I got a reply to a complex letter for increasing the power from 5kW to 13kW and there are:
"2. The operator determines the connection fee for the amount of 106.04 (say: PLN one hundred six and 04/100) + VAT (23%), i.e. PLN 130.43 gross , which is the product of the increase in connection capacity, the coefficient of simultaneity kj = 0.213 and the rate of PLN 62.23 for 1kW + VAT (23%), t j. PLN 76.54 gross ".
And so it came to me from the calculations: 8kW * 0.213 * 76.54 = 130.43 PLN.

Someone on the forum wrote that these are amounts around 80 PLN / kW, so I suggested one post on the forum to apply for the lowest power for a given security, ie from 12-13kW already 25A. If I knew that it would be PLN 16 instead of PLN 80 per kW, I would probably ask for 16-18kW immediately.

I understand that such power should be enough? I'm not an electrician, so I know if I took the calculation well. Only the induction hob will run on two phases simultaneously. The rest of the devices will be on the 1-phase (separated between 3 phases).

Since there is no need to use a water heater or electric heaters, the 3x25A protection is enough.
As for the calculations, it looks like the mistake of the person who worked out the conditions. The coefficient of simultaneity is used to calculate the connection power for a multi-block building and does not affect the power charges for a single apartment.

It can not be counted like this.
Ask the kobity - what he wants to do at the same time.
Kobita determines the simultaneity.

Ask what power you have to insert in order to have 25A pre-meter protection.

Taż writes you like an ox, that 62.23 for 1 kW + 23% VAT. Problems with reading? STOEN has pressed you the coincidence factor, you do not have 13 kW at all.

When it comes to calculations, maybe it costs so much. As far as I know, in the block most residents have 1 phase and power about 5kW, they were exchanged some time ago (counters, WLZ for apartments 5x6 mm2). Increasing power is now just replacing the installation of a 3-phase meter and changing the fuses.

What are you talking about? A total of PLN 130.43 is issued from the magazine. The difference between the present power (5kW) and the requested power (13kW) is 8kW. If you accept the calculation according to STOEN information it comes out
8 (product of power increase) * 0.213 (coefficient) * 62.33 PLN (price for 1kW net) = which gives 106 PLN net, or 130 gross.

That is, for the additional 8kW comes exactly as much as they wrote (PLN 130.43 gross)

And the installation in the apartment you have adapted for 3-phase power supply?

Yes, some time ago there were all pions with meters and WLZs. I currently have 5x6 mm in the flat.
Not to prolong - I understand that the proposed 13kW should be enough. At STOEN, they said that they would then provide 3x25A security, i.e. I still have a buffer of about 3kW for maximum power on these protections (16kW from what I know). I think well?

I understand that exceeding the power by individual recipients does not entail additional charges, i.e. as if I took, for example, 15kW, and I have a connection power of 13kW. I ask, because on the meter I can see the indication of the maximum power consumed (I just do not know in which period). I associate that such restrictions (additional charges for exceeding the power) are for larger plants.

For an additional 8 * 0,213 = 1,704 kW. Be serious. You will eventually have approx. 7 kW of power.

So from what you wrote it follows that I will pay for 1,704kW. So I will get 13kW (extra 8kW) for 130.43 PLN. I understand that the error is that there should not be a coefficient here and the fee should be 8 * 62.33 net = PLN 498.64 net, i.e. 613,33 PLN gross . That's it? At the beginning of the connection conditions it is clearly written:

"Innogy STOEN agrees to power supply with power:
connection terminal 13kW - increase by 8kW
supply voltage 0.4 / 0.23kV "

and next

"2. Innogy Stoen Operator determines the connection fee for the amount of 106.04 (in words: PLN one hundred six and 04/100) + VAT (23%), ie PLN 130.43 gross, which is the product of the increase of connecting power, coefficient of simultaneity kj = 0.213 and rates in the amount of PLN 62.23 for 1kW + VAT (23%), ie gross PLN 76.54 ".

Show in conditions you have a pre-meter protection. And what you need to change at your own expense.

"4. The commencement of electricity supply will be possible after:
a) execution by the Customer of an internal power supply line from the building's internal installation
b) execution by the Customer of the receiving installation in the facility

7. Additional conditions
7.1 Protection in ZK adapted to the cross-section and load of the inlets.
7.2 Pre-meter protection with over-current circuit breakers with a value of 25A , adapted for sealing
7.3 Surge arresters should be used in the customer installation.
7.4 In the Customer's installation, do not install receivers that cause excessive strain distortion (acceptable content of higher harmonics in accordance with the Min. Of the House of Commons dated May 4, 2007 on specific conditions of the power system operation) "

So on my side
1. WLZ to the apartment - it is already
2. Receipt (measurements, bar diagram)
3. Security in the switchgear in the apartment (surge arresters, etc.)
4. Changing the pre-meter protection to 25A

On the supplier's side:
1. Changing the meter to 3-phase

In the contract in the duties of the client (paragraph 6) there is such an entry:
2. The Customer undertakes to carry out the electrical installation in the own premises at the expense and effort, only by legal or natural persons having the authorization to carry out such works, from the place where the customer's network and installation are separated.

So I think that the whole installation in the switchgear in front of the meter, behind the meter and in the apartment is on my side (including the pre-meter protection), and the operator only changes the meter?

I do not have a contract with me right now, but it is identical to the contract of a friend of yak in the subject https://www.elektroda.pl/rtvforum/topic3318367-150.html.
