Altus Energy

What Altus Energy does

Altus Energy is a privately held French solar energy developer-operator founded in 2008 and headquartered in Valbonne (Sophia Antipolis). The company manages the full lifecycle of medium-to-large photovoltaic power plants (250 kWc to several MWc), covering project identification, land acquisition, development, financing, construction steering, commissioning, and long-term operational management and maintenance. It targets agricultural and industrial building owners, municipalities, private landowners, and financial investors across France, retaining ownership of the assets it develops and operating a France-wide maintenance network with telemonitoring and remote monitoring across its installed base.

Core products include ground-mounted and rooftop photovoltaic installations, with underlying technology centered on conventional solar panels, inverters, and substations supplemented by in-house telemonitoring systems, thermal imaging diagnostics, and current-clamps for rapid fault intervention. The company has developed and financed approximately 130 MW of capacity across France and reports that all its generators meet budget and production forecasts. It also operates a subsidiary, THIRD STEP (founded 2012), which extends the same integrated model into China.

Altus Energy generates revenue through multiple streams: solar project development and financing (over €160 million in cumulative debt and equity raised since 2008), construction management and EPC services (95 MW of ground-mounted plants built in 2014-2015), long-term operational management, predictive and reactive maintenance for both owned and third-party plants, and equipment supply to solar industry operators. Distribution is direct, with no reseller network, relying on field-based enterprise sales to landowners, municipalities, and investors alongside a multilingual corporate website (French, English, German) and athlete-sponsorship branding.
