Pros and cons
Endesa
Pros
- Exit fee of €0 means a fixed term can be ended early without a charge, which is unusual in this group.
- Unit rate of €0.12 and standing charge of €2.85 sit at the competitive end of the suppliers listed here.
- A tethered home charger costs €1,099 with installation included, gives power of 7.4 to 22 kW and carries a warranty of 3 years.
Cons
- Tariff choice is narrower than some rivals: fixed, time of use and ev covers fixed, time-of-use and EV, while Powerpeers lists dynamic, fixed and variable.
- A green tariff does not appear in fixed, time of use and ev, though Electricity Ratings includes fixed, ev and time of use.
- Coverage is limited to Spain, Canarias and Baleares, so households in other markets need a different supplier.
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
Endesa
Who it suits
- Households in Spain, Canarias or Baleares that want electricity and gas from one supplier with an exit fee of €0.
- EV owners who want a tethered charger fitted at home and linked to the electricity tariff.
- Customers who expect phone help, since email, chat and phone includes phone and chat alongside email.
Who should look elsewhere
- Powerpeers readers who want a dynamic or variable tariff, since dynamic, fixed and variable lists both and fixed, time of use and ev does not.
- Anyone set on a green tariff, which Electricity Ratings offers in fixed, ev and time of use but Endesa does not list.
- Households outside Spain, Canarias and Baleares, and readers who prefer the fixed-only setup of Base Power Company in fixed.
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.
