Everyday convenience and benefits without the stress of electricity price spikes.

“With three kids and both of us working from home, keeping track of electricity market prices isn’t exactly top of mind. It’s great that I can still earn benefits from my energy use with Smart Rewards”

Juuso Rantaniitty lives in a detached house, heats his home with a water-based heat pump, and owns an electric car. Right now, the daily hustle doesn’t allow living according to fluctuating electricity prices, but Synergi Smart Rewards program provides valuable benefits for charging his EV without disrupting his routine.

“I just plug in the car and enjoy watching the points add up – my daily life hasn’t really changed because of it. I first heard about Synergi in the Tesla Club Finland group and was immediately interested in the rewards feature. Setting up the app was easy with my car login, and using it has been very straightforward.”

A Nintendo gift card as a thank-you for helping balance the grid

In just over just four months of use, Juuso has earned slightly over €40 in rewards. With three kids at home, the family decided together how to use the rewards, and the most attractive option was a Nintendo gift card.

“My oldest son suggested I could get a new game with it.”

For Juuso, the biggest advantage of Synergi is earning rewards from energy use without the risks that come with a spot-price electricity contract. At the same time, contributing to the common good is also appealing.

Synergi’s Smart Rewards helps stabilise the electricity grid by providing support when it’s needed most. EVs participating in Synergi’s collective virtual power plant act as a safety net for the grid whenever consumption needs balancing. Synergi receives compensation for this service and passes it on to EV owners as rewards.

“With a spot-price electricity contract, I might be able to save more, but in my situation, supporting grid stability while earning Synergi rewards is the better choice. I simply keep the car plugged in whenever I’m home – and so easily, I gain meaningful benefits.”

Coming soon: Charge and earn rewards
