About CleverNett
Time to accelerate the transition.
formerly Nett Energie
As business owners, we are increasingly exposed to the volatility of the energy market. Sudden price spikes, evolving regulation and geopolitical uncertainty force us to rethink how we secure our future energy supply.
Facing this transition, most companies lack a plan that is both climate-aligned and economically sound. How can businesses contribute to decarbonisation without derailing their operating budget?
We are CleverNett, a Belgian developer of renewable electricity. We are convinced that corporate PPAs are the right instrument for companies that want to chart their own course — independent from the volatility of the wholesale grid — with a strategy where price stability and CO₂ reduction reinforce each other.
At CleverNett, businesses don't have to invest in a solar asset or manage its operations. We offer the simplest possible model: in exchange for the use of your rooftop, we deliver renewable electricity at a fixed rate for 25 years.
Without a rooftop, you're equally welcome — our platform matches you with local producers. No shifting of guarantees of origin: every new contract translates into the actual construction of additional renewable capacity in Belgium.
Choose price clarity, and accelerate the transition together with other forward-looking businesses.

A word from the founders
Today, we make the difference.
CleverNett was founded by Arthur Despiegelaere and Emile Steyaert, who run the company together day-to-day. Arthur comes from data analysis, Emile from real estate development. That combination is no coincidence: building hybrid solar parks and running them smartly requires both a feel for numbers and a feel for locations, structures and long-term projects.
Together they develop and manage the CleverNett solar parks — solar and battery — optimised day after day.
