The Battery Development section - HUGE !From my experience in Grid systems, I am predicting that by the end of the decade - battery deployment for energy storage will have become the new standard - the presently "missing" link to providing system reliability - GREEN energy when the Sun isn't shining, and the wind isn't blowing - and improving frequency stabilization and load management capabilities no matter what the generation source is ! Not much buzz about that yet - but it is an emerging market - think if there had been general deployment of battery storage in the recent Texas - Storm Uri emergency !
