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
niba
Pros
- An exit fee of €0 means switching costs nothing, which places niba in the no exit fee group.
- Renewable supply of 100% covers the whole plan, and an export rate of €0.06 rewards rooftop solar.
- A standing charge of €0.091 keeps the fixed part of bills small for light users.
Cons
- The unit rate of €0.12 sits above the cheapest tariffs in the comparison, so heavy users pay more for each unit.
- Sales cover ES only, across the Iberian Peninsula, so there is nothing on offer for households elsewhere.
- Endesa and Electricity Ratings both list an electric vehicle tariff, while the niba range is fixed, time of use and dynamic.
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
niba
Who it suits
- Households in Spain that want to leave a fixed contract without paying an exit fee.
- Homes with rooftop solar that want renewable supply plus an export rate.
- People who want electricity and gas together across fixed, time of use or dynamic pricing.
Who should look elsewhere
- Electricity vehicle drivers: Endesa lists fixed, time of use and electric vehicle tariffs (fixed, time of use and ev), and a charging rate is the point for them.
- Anyone after a variable or prepay choice: Powerpeers lists dynamic, fixed, variable and green (dynamic, fixed and variable).

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.
niba
What does it cost to leave niba?+
Nothing. The exit fee is €0, so you can end the contract without paying to walk away. The fixed term runs 12 months, so the commitment stays short and an earlier switch costs nothing. That makes niba a low risk contract to try first.
How much is the energy itself?+
The unit rate is €0.12 and the standing charge is €0.091. The unit rate moves with how much you consume, while the standing charge is the fixed part you pay regardless. Light users notice the fixed part most, heavy users notice the unit rate most.
