Orus Energy secures €2.2M to help decarbonise the power grid

Energy flexibility platform Orus Energy, has raised a 2.2 million pre-seed round to help decarbonize the power grid.

By optimizing the aggregated flexibility of numerous buildings, Orus' software dynamically adjusts energy usage, shifting it to times when electricity is cheapest and greenest, thus providing valuable flexibility to the electricity grid.

Leveraging machine learning, the platform predicts electricity consumption and flexibility needs in buildings. Then, it enables intelligent and dynamic control of the electricity consumption for a range of flexible energy-consuming assets like heat pumps or thermostats. The demand response platform interfaces with control systems deployed at scale, to shift power demand without impacting occupant comfort, thanks to the thermal inertia of buildings, and remunerates clients up to 10 percent of their electricity bill for doing so. 

The funding round was led by b2venture and top French impact funds Asterion Ventures and Ring Capital. The round also gathers several angel investors from the industry, including Pierre Trémolières (Accenta.ai) and Myriam Maestroni (e5t). 

“Orus Energy's mission is to enable decarbonized power grids through consumer involvement.” commented co-founder Alexandre Girard. “Our approach is unique: by using buildings as thermal batteries at scale, we can help unlock 6 gigawatts of power demand in France alone by 2030.”

“The power grid has become the Achilles' heel of the energy transition. The rise of intermittent renewable energies on one hand, and the increased electrification of uses with the advent of electric vehicles and heat pumps on the other, are putting more and more pressure on the power grid” states Fanny Sauvée, co founder and COO at Orus Energy. “The grid's critical role in balancing production and consumption at all times is becoming increasingly challenging.”

In this evolving energy landscape, demand-side flexibility becomes a cornerstone of the transition to a resilient energy system that fully integrates renewables. Modulating the power usage of flexible equipment such as heating, EV charging, and systems based on grid demands directly reduces reliance on polluting peak periods.

While demand-side flexibility has proven effective in the industrial sector, generating €1.3 billion in France in 2022, it has reached its limits. Commercial buildings, which account for over a third of peak electricity consumption, offer the greatest potential for scalable flexible power.

Since its commercial launch in 2023, Orus Energy has rapidly gathered attention and adoption from both commercial and office buildings owners and facility managers. Winner of the recent call for projects of La Caisse des Dépôts, Techsprint, Orus Energy already counts over 1 million m² of real estate space registered on its platform and deployed its solution in high-profile clients' buildings including retail giant IKEA and real estate leader La Poste Immobilier. 

“Alexandre, Fanny and Théophile are outstanding talents and form a great team that is tackling huge problems” says Florian Schweitzer, founding partner of b2venture. “Making smarter use of our energy grid and leveling out peak demand and supply of energy is a worthy mission that can have a huge impact on society and bring enormous benefits to the economy.”
