Three weeks and a bit — from 23 April to 12 May. This period covered the May long weekend ("majówka"), another long weekend and a trip to Mieroszów for a friend's funeral. In total: 2418 km, 437.32 kWh used, an average electricity price of 1.62 PLN/kWh.
That works out to:
| Metric | Value |
|---|---|
| Kilometres | 2418 km |
| Energy used | 437.32 kWh |
| Average consumption | 18.08 kWh/100 km |
| Average electricity price | 1.62 PLN/kWh |
| Total electricity cost | ~708 PLN |
| Cost per 100 km | ~29.30 PLN |
This also includes the trip to Mieroszów — 1066 km, two days and ~392 PLN for electricity. That trip pushed the average up, because an unplanned dash always costs more.
Ekoen over the May long weekend — charging at half price (and it could have been almost free)
Over the May long weekend Ekoen ran a promotion. It was sunny, the solar panels were doing their job, so you could charge for under 0.50 PLN/kWh, and at some hours for as little as 1 grosz. I picked a slot at 0.34 PLN/kWh — at least the queues weren't long. I could have aimed for the "pennies" price, but fighting for a spot during the promo's peak hours isn't my thing.
It's great that Ekoen runs campaigns like this. They have fast 350 kW chargers, their everyday prices are good, and on top of that there are promos like this. Super.
This is also part of the answer to why the average for this period came out at 1.62 PLN/kWh rather than 1.86 like on a classic Ionity route. A few really cheap stops over the long weekend pulled the top end down considerably — Ekoen at 0.34 PLN and the Supercharger on Al. Krakowska at 0 PLN (referral programme) did the job.
What's left of it
29.30 PLN per 100 km is a decent result for a period in which one of the two longer trips was completely unplanned. A combustion car over the same kilometres, at 6 l/100 km and 6.50 PLN/l for Pb95, would have come to ~39 PLN/100 km — a few zloty more. Not a cosmic difference, but it's there.
The Ekoen promotion also showed that when an operator wants to, solar-powered electricity prices can be truly ridiculous. The only question is whether this will stick as a permanent offer or remain an occasional campaign. For now I treat it as a nice bonus, not the rule.
