Pros and cons
Alperia
Pros
- Exit fees are €0, so leaving early carries no charge on the green plans
- Green supply runs at 100% renewable, backed by certificates
- A €0.13 unit rate that ranks ahead of many suppliers on unit rate alone
Cons
- Supply is limited to Trentino Alto Adige, so most of the country cannot switch to it
- The standing charge of €109 ranks mid-table rather than near the cheapest
- Green claims rest on certificates rather than on the supplier's own generation
Green Planet Energy eG
Pros
- The exit fee is €0, which places Green Planet Energy eG at 1 of 29 brands, so leaving later costs nothing.
- Renewable supply of 100% rests on own generation, so the green claim comes from the cooperative's own generation rather than bought certificates.
- Tariff types cover green, variable and dynamic, so a household can pick a green plan, a variable rate, a dynamic rate or an electric vehicle rate.
Cons
- The standing charge of €16.57 ranks 10 of 16 brands, so a low usage home pays more for the connection than most rivals.
- The unit rate of €0.17 ranks 9 of 23 brands, which is mid table rather than a standout for anyone shopping purely on unit cost.
- A smart meter is required, so the tariff cannot start until a compatible meter is fitted, which adds a step to every switch.
Who each suits
Alperia
Who it suits
- Households in Trentino Alto Adige that want renewable electricity at a fair unit rate
- Anyone planning to move house or supplier within the fixed term, since exit fees are €0
- EV owners who want solar divert and installation included with their charger
Who should look elsewhere
- Households outside Trentino Alto Adige, since it serves IT only
- EV drivers who want a time of use tariff, which Powerpeers and Endesa both list
- Shoppers chasing the lowest unit rate in the market rather than a fair mid-table one
Green Planet Energy eG
Who it suits
- Households in DE already on a variable or dynamic rate who want to move to renewable electricity without paying to leave.
- EV owners who want charging priced on the supplier's electric vehicle tariff rather than on a standard rate.
- Gas and electricity households who would rather keep the same cooperative than split the account between suppliers.
Who should look elsewhere
- Endesa buyers, since these tariffs run in DE while Endesa lists fixed, time of use and ev for Spanish households.
- Powerpeers buyers who want a fixed rate from a supplier listing dynamic, fixed and variable, since the range here is green, variable and dynamic.
- Electricity Ratings buyers after a prepay meter, since fixed, ev and time of use includes prepay and the range here is green, variable and dynamic.

Questions about each
Alperia
Does it cost anything to leave Alperia early?+
No. Exit fees on the green plans are €0, so you can switch supplier before the term ends without a charge. Fixed terms still run for 12, 36 and 60, but the commitment does not come with a penalty for walking away from it.
How renewable is the green electricity?+
The green plans are described as 100% renewable. That claim is backed by certificates rather than by electricity the supplier generates itself, which is worth weighing if you prefer supply from owned generation.
Green Planet Energy eG
What does Green Planet Energy eG cost?+
The unit rate is €0.17 and the standing charge is €16.57, and those charges together make up a typical bill. The unit rate ranks 9 of 23 brands, so the price sits in the middle of the range rather than at either end.
Is there an exit fee if I want to leave?+
The exit fee is €0, which places Green Planet Energy eG at 1 of 29 brands. Nothing has to be paid to switch away, which matters for anyone who expects to move home, split with a partner or change supplier later.
