Solutions

Two ways we work with you

For businesses

C&I storage solutions

Lower energy bills, more from your grid connection and backup for critical loads. We size, install and run storage on your site, and can connect it to flexibility markets for extra revenue.

For investors and asset owners

Flexibility projects

Storage assets that earn from frequency regulation, energy trading and capacity reserve. We develop, finance, build and operate them.

One partner from site to revenue
