What's the dynamic SimplyDynamic tariff?

At Ostrom, we have been working hard to offer our customers the opportunity to use electricity when it is cheapest. This is now possible with our dynamic tariff offer. Simply sign up for SimplyFair, and if you have a supported smart meter installed, you will be automatically switched to SimplyDynamic.

What does this mean for you?

• Your electricity consumption will be billed by the hour at the current electricity price on the stock exchange.

• This allows you to shift your consumption to low-cost hours, such as at night or when there is a lot of sunshine, and thus save money day after day.

• Our app allows you to keep an eye on both your consumption from the previous day and the electricity price on the stock exchange, so you can only use electricity when it is the cheapest.

You can find more infos here.

Please note: In order to use our dynamic tariff, we first need to check if you have a smart meter ( intelligent measuring device with a BSI-certified smart meter gateway).

Feel free to send us a picture of your meter via chat, and we'll be happy to check it for you! 😊
