Pinergy vs PrepayPowerWhich is cheaper for you?
Both suppliers run several plans, and the cheaper one depends on how your home uses electricity. Here's who wins for different kinds of household.
The short answer
There's no single answer — and that's exactly the point. Pinergy is cheaper for some homes, PrepayPower for others. It all comes down to when you actually use electricity.

Find my cheapest planPinergy vs PrepayPower — frequently asked
Is Pinergy cheaper than PrepayPower?▾
Not always — it depends on your home. Pinergy works out cheaper for some usage patterns and PrepayPower for others (see the breakdown above). An EV owner who charges overnight and a household that's out all day can get opposite answers from the same two suppliers.
Why isn't there one "cheapest" plan?▾
Because electricity plans charge different rates at different times of day. A night-saver plan is the cheapest thing going for an EV owner charging at 3am, and one of the dearest for someone home all day. The "best" plan depends entirely on when you use power — so a single league table is misleading.
How do I find which is actually cheapest for me?▾
Link your smart meter to SmarterMeter (free). We rank every plan from every supplier against your actual half-hourly usage — not an average household — so you see your real cheapest plan, not a generic winner.
Can I switch between Pinergy and PrepayPower?▾
Yes. Switching electricity supplier in Ireland is free, takes about two weeks, and there's no interruption to your supply — the wires and meter stay exactly the same.
