Pros and cons
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.
Octopus Energy
Pros
- Exit fee is €0, so a fixed term can be left early without a penalty
- Green tariff is backed by 100% renewable supply on a certificates basis
- Tariff choice covers fixed, variable and green on both electricity and gas
Cons
- Fixed terms run 12 months and then need a renewal decision, since no separate renewal price is set out
- Unit rate of €0.17 sits mid-field, so it does not undercut every rival on usage
- Tariff list covers fixed, variable and green only, with no time of use or electric vehicle option as listed
Who each suits
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.
Octopus Energy
Who it suits
- Italian households in IT who want to switch supplier without paying to leave
- Households that want a green tariff on a certificates basis at 100% renewable supply
- People who prefer fixed pricing but want an exit fee of €0 behind it
Who should look elsewhere
- Households wanting an electric vehicle or time of use tariff, since fixed, variable and green does not list them
- Anyone outside IT, where the supplier does not operate
- Households chasing the lowest unit rate, where €0.17 is only mid-field

Octopus Energy

Which markets does Octopus Energy serve?+
Octopus Energy sells in IT only, so the tariffs and support described here apply there. Anyone outside that market will not find these offers, and would need a supplier operating in their own country.
