Problem
Businesses face unpredictable energy prices and rising operational costs, with many lacking the technical expertise to identify and implement effective consumption-reduction measures. Traditional energy management approaches often rely on generic solutions that fail to account for a company's specific consumption patterns, leading to suboptimal savings and missed opportunities for financial and environmental gains.
Solution
Onersa provides a comprehensive energy optimization service that combines detailed consumption analysis with tailored efficiency interventions. The company's methodology, validated by the international consultancy Leyton, uses real consumption data to establish a baseline and measure savings with precision, ensuring compliance with regulatory standards for energy savings certificates. Onersa designs custom solar self-consumption systems and applies patented technology to reduce electrical losses, delivering verified reductions in energy use and costs. The company's approach prioritizes direct self-consumption over surplus sales, maximizing the financial return for clients by focusing on the energy they avoid purchasing from the grid.
