John Grandfield gives a comprehensive commentary on the Aluminium Industry's response to Climate Change. He mentions specifically mentions the EnPot technology:
"Another opportunity is to modulate smelter power consumption so the smelter performs essentially as a battery in the grid with quick response to renewable energy variation. EnPot technology, developed by Energia Potior Ltd in New Zealand is an enabling technology to improve the smelters modulating ability. Far greater impact to the grid stability is possible than with current battery systems".
