"To complete this project in the near future requires hard work," said South Australian Minister of the Interior, Jay Weatherill in an official statement. "The largest lithium ion battery in the world will be an important part in our power source."
Musk was the subject of talk when he promised to build Powerpack-based backup power system within 100 days. At that time he promised that if Tesla failed to complete the project within a specified time, then the South Autralia did not have to pay the cost of a penny project.
Musk said, the countdown will begin when the contract is signed. By that time on September 29th, Tesla had actually completed half of this project.
However, Tesla successfully completed the project 45 days sooner than promised. If you do not count the weekend, then Tesla actually did complete this electricity backup project 99 days after Musk declared his promise.
The next step is to test the Powerpack system designed to provide backup electricity at about 30 thousand homes for the number of homes that went down in September last year.
Critics of wind and solar energy say these two sources are unreliable, unlike nuclear or coal. The reason the wind sometimes does not blow and the sun does not shine.
With the existence of a backup lithium battery system made by Tesla, the extra energy generated when wind and solar power generation is productive can be stored and used when both power plants are unproductive due to unfavorable weather.
