STORAGE
Who are we?
Ambos is a key player in electricity storage. It contributes to the energy transition by enabling an increase in the share of renewable energy in the energy mix, offering a « flexibility » solution to bridge the gap between renewable energy production peaks and electricity consumption peaks.
As true tools for preventing grid saturation, energy storage infrastructures have become essential accelerators for the energy transition.
Ambos also positions itself as a partner for local authorities, farmers, and industries, working closely with them to find the most relevant solutions for optimal value sharing.
OUR VALUES
Entrepreneurship
Led by its CEO, an entrepreneur at heart, Ambos believes in innovative models and is convinced that complex projects generate dynamism, enthusiasm, and substantial value creation.
Commitment
Driven by its CFO, with a decade of experience in major investment banks, Ambos ensures that all efforts are focused on achieving its objectives in project management and business operations.
Proximity
Ambos positions itself as a local player with teams in Paris, Toulouse, Montpellier, Gaillac, Nantes, and Dijon. Special attention is given to generating and sharing value at every stage of our projects with local partners (territories, farmers, industries, crowdfunding).
Adaptability
Ambos is a human-sized company with simplified governance that enables quick decision-making, while benefiting from significant financial resources. This flexibility allows the development of complex, high-value projects in a constantly evolving energy market.
OUR SOLUTIONS
We develop and operate storage assets designed to serve as flexibility assets on behalf of grid operators or aggregators.
En permettant un meilleur équilibre du réseau et un ajustement de l’offre By enabling better grid balance and adjusting supply to match electricity demand, these assets become essential tools for the integration of renewable energies into the grid. They contribute to energy independence and reduce the need for fossil fuels during consumption peaks.
Leveraging its network of partners (co-developers, grid management experts), Ambos specializes in high-capacity projects (from 100 MW) known as ‘stand-alone’ BESS (Battery Energy Storage Systems), which serve as powerful flexibility tools. We exclusively develop isolated projects, located near connection points (private or public substations, and under high-voltage lines at the exit of power plants).
We are the preferred partner for:
• Developers seeking funding support to bring their projects to completion.
• Local authorities, farmers, and industries near an RTE substation looking to capitalize on underused or unused land.
Reduction of infrastructure needs and costs for the end user
Batteries store excess energy and release it during demand peaks, reducing the strain on electrical grids and the investments required for their reinforcement.
