This document discusses Ecoult's UltraBattery technology for managing variability in renewable energy sources using large-scale energy storage. The UltraBattery combines lead-acid battery and ultracapacitor technologies. It has applications that include smoothing fluctuations from wind and solar power, shifting solar energy to meet evening demand, and providing grid services like frequency regulation. Ecoult offers complete energy storage systems and a lifecycle management program called UBer that supports project development, installation, operation and maintenance.
