Tesla CEO Elon Musk said the ability of grid-connected big battery to deliver significant savings and make money on its own account had made it a great success, both technically, and economically.
“The Hornsdale project has generated substantial savings and is likely to pay for itself within a few years,” Musk said in comments on Tela’s latest quarterly results.
“This has generated interest from governments and municipalities to invest in large battery storage projects rather than in conventional peak energy generation.
“In addition to providing backup generation and cost savings to businesses, Powerpack units are now used in over 100 microgrid projects across 32 countries.”
Musk said that Tesla had deployed 1.04GWh of battery storage in 2018, a three-fold increase over the previous year, and expects this growth to double again in 2019 as a new manufacturing line at Gigafactory 1 in Nevada boosts the output of both Powerwall and Powerpack modules.
