Spring in a nutshell

We connect various consumption-side assets and batteries to our platform and provide this harnessed capacity to various energy markets, including ancillary services, via Fortum’s trading system. By utilising the already existing assets for balancing services, we can create additional revenue streams for the asset owner and help the increased renewable production to integrate better to our energy system.

Our strategy
Our business is based on partnerships. In our business model, we generate new value that we then share with the customer. And since the customer owns the asset, we think that it’s only fair that the customer gets the biggest share of the generated value. We do our best to generate as much value as possible without harming the original purpose of customer's asset. Because we aspire to be a trustworthy partner to our customer, we are 100% transparent about the value that we generate.
