FAQ
TL;DR: A 14 kW home connection costs a one-off ~2 500 PLN but adds 0 PLN/month in G-tariff capacity fees; “There are no capacity-related charges in the G tariff group” [Elektroda, zbich70, post #12718909] Capacity uplift at PGE is 7.87 PLN per kW [Elektroda, stomat, post #16303273]
Why it matters: Choosing the right power and tariff prevents surprise bills during and after construction.
Quick Facts
• One-off connection fee: 14 kW ≈ 2 500 PLN incl. VAT [Elektroda, sputnik1, post #12723131]
• Capacity uplift price (PGE): 7.87 PLN / kW [Elektroda, stomat, post #16303273]
• Monthly capacity charge in G-tariff: 0 PLN [Elektroda, zbich70, post #12718909]
• Typical capacity charge in C-tariff: ~25 PLN/month for 14 kW [Elektroda, stomat, post #12720013]
• Average Polish household use: ~2 000 kWh/year [Eurostat, 2022]
Will a 14 kW connection raise my monthly bills compared with 7 kW?
No, if you are billed on the household G-tariff. That tariff has no standing charge per kilowatt, so 7 kW and 14 kW cost the same each month once the connection is built [Elektroda, zbich70, post #12718909]
Why do builders warn about higher fees with more power?
During construction you are often placed on the business C-tariff, which adds a capacity charge. At 14 kW that can be about 25 PLN per month [Elektroda, stomat, post #12720013] Once you switch to G-tariff the extra fee disappears.
How big is the one-off connection fee difference between 7 kW and 14 kW?
Distribution operators price the connection per ordered kilowatt. The poster paid about 2 500 PLN for 14 kW; 7 kW would have been roughly half that [Elektroda, sputnik1, post #12723131]
Is 7 kW enough for a modern single-family house?
Many users find 7 kW too low; appliances can trip a 1-phase fuse. “14 kW is the minimum” for current loads [Elektroda, stomat, post #12719249]
Will a 14 kW service be single-phase or three-phase?
Utilities deliver 14 kW only as a three-phase supply. Single-phase is usually capped near 7 kW [Elektroda, bartekfigura, post #12718864]
What is connection group V mentioned in my contract?
Group V covers customers up to 40 kW, up to 1 kV voltage, with meter fuses ≤ 63 A [Elektroda, bartekfigura, post #12723293]
How do I change from C-tariff to G-tariff before house completion?
Submit a written request, include an electrician’s statement that the house is inhabited, and pass a utility inspection. One user switched this way without an occupancy permit [Elektroda, grzeskk, post #12726490]
Can I start with 7 kW during construction and upgrade to 14 kW later?
Yes. PGE charges 7.87 PLN per added kilowatt when no network work is needed—55.09 PLN to move from 7 kW to 14 kW [Elektroda, stomat, post #16303273]
What happens if 7 kW proves insufficient?
Frequent breaker trips occur, forcing manual resets or fuse replacements—an avoidable nuisance [Elektroda, stomat, post #12719249]
Are there edge cases where G-tariff users still pay capacity fees?
Only if mis-classified. Some builders were wrongly left on C-tariff; after complaint and regulator review, fees were refunded [Elektroda, masonry, post #12724198]
