Granarium Technologies targets grid stability with supercapacitors
Granarium Technologies is addressing the need for instant power stabilization in increasingly electrified and decentralized energy systems, CEO Paula Viinamäki told CB Insights. The company uses renewable-material supercapacitors.

Granarium Technologies is providing solutions to enhance industrial power reliability and grid stability using supercapacitors made from renewable materials.
The company's technology aims to meet the growing demand for immediate power stabilization as energy systems become more electrified, reliant on renewables, and decentralized. Granarium estimates its initial serviceable market in Europe alone includes 500,000 to 1 million industrial and energy sites where power quality and system reliability are critical.
Target applications span industrial facilities, renewable energy assets, data centers, utilities, and hybrid systems, where fast-response power improves uptime and dependability. A primary issue Granarium addresses is enabling instant power response, facilitated by its supercapacitor technology.
These supercapacitors support 24/7 operations and stabilize dynamic power systems, complementing batteries in applications where milliseconds matter. Granarium's focus is on ensuring uninterrupted operations for critical industrial and energy sector activities.
CEO Paula Viinamäki highlighted that the company's technology provides the rapid power supply necessary for the effective and reliable functioning of modern, increasingly electrified, and decentralized energy grids.
