Pros and cons
Base Power Company
Pros
- fixed at $0.08 holds for a term of 36 months, so the rate you enter on is the rate you pay through the term.
- Help is offered on email, chat and phone, so a query can go to phone or chat rather than waiting on email.
- The footprint spans Oncor, CenterPoint and AEP Texas Central, so a meter on either an Oncor or a CenterPoint network, or on ComEd, is in scope.
Cons
- Tariff choice is a single type, fixed, against fixed, ev and time of use at Electricity Ratings and fixed, time of use and ev at Endesa.
- Supply is electricity only, electricity, so a combined electricity and gas bill has to be arranged elsewhere.
- Availability is TX and IL only, across Oncor, CenterPoint and AEP Texas Central territories, so a meter sitting on another network has no plan here to move to.
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.
Who each suits
Base Power Company
Who it suits
- Households on the listed footprints, Oncor, CenterPoint and AEP Texas Central, that want a rate held rather than one that moves.
- Single-fuel electricity customers who are content with fixed as the only type on offer.
- People who want phone and chat support, both part of email, chat and phone.
Who should look elsewhere
- Anyone after a time-of-use or electric vehicle tariff: Endesa lists fixed, time of use and ev.
- Buyers looking for a dynamic or green plan: Powerpeers lists dynamic, fixed and variable.
- Households that want prepay or green options: Electricity Ratings lists fixed, ev and time of use.
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.

Questions about each
Base Power Company
What does the plan cost per unit of electricity?+
The published unit rate is $0.08, and the plan is listed as fixed. That is the per-unit figure, so the bill also picks up a standing charge. Compare the unit rate and the standing charge together rather than weighing one line in isolation.
How long does the price last?+
The term runs 36 months and the tariff type is fixed, so a single unit rate of $0.08 applies across the whole term instead of resetting part way through. A different rate applies once that term is over, which is the point to plan around if your usage is likely to change.
Endesa
Does it cost anything to leave an Endesa contract early?+
The exit fee listed for the Conecta de Endesa plan is €0, so ending a fixed term early carries no charge. That stands out among the suppliers in this comparison, several of which price a fee for switching. It makes Endesa easier to move away from if wholesale prices move against you later.
What does a unit of electricity cost from Endesa?+
The unit rate on Conecta de Endesa is €0.12, with a standing charge of €2.85 added to the bill. In this comparison the unit rate ranks 6 of 23 and the standing charge 3 of 16, putting both figures near the competitive end of the group.
