Polarium is the market leader in reserve power for telecom towers where the greener Li-ion technology substitutes lead-acid batteries and diesel generators. To date, Polarium has implemented over 350,000 installations in more than 70 countries on all continents and in all climate zones – from the Equator to the Arctic. With production facilities in Mexico, South Africa and Vietnam, Polarium has grown with around 150% annually between 2016 and 2021.

Within Energy Optimization, Polarium uses battery modules and smart algorithms to help customers significantly reduce energy costs while at the same time contributing to stabilize and maximize utilization of the existing electric grids. Energy optimization is a fast-growing segment as a consequence of the high and volatile energy prices the world see today.

Polarium creates significant impact in greening and electrifying the energy system as well as the telecom sector. Li-Ion reserve power installations reduces diesel consumption and avoids hazardous lead-acid recycling processes. The company takes responsibility in greening the supply chain for battery modules, trough e.g. a long-term partnership with Northvolt on green battery cells. Batteries are also the missing link in a renewable energy system as smart and distributed energy storage is crucial to allowing more intermittent energy sources, such as wind and solar, into the electricity mix. To meet the targets in the Paris Climate Agreement, the International Energy Association estimates a need of more than 3,000 GW of batteries in the grid by 2050, almost 200 times more than the world has today.
