Now, the Elon Musk-headed venture is vying to build another massive Powerpack system in Colorado for Xcel Energy Inc., an electric utility operating in eight Western and Midwestern states.
Here's how massive Tesla's battery could be, as Electrek detailed:
"In South Australia, Tesla's 100MW/ 129MWh Powerpack project is known as 'the most powerful battery system in the world' and while this proposal in Colorado would not be as powerful with a power capacity of 75 MW, it would be able to run for 4 hours, which would require a much bigger energy capacity of 300 MWh.
"It would be a major energy storage project that would represent twice the energy capacity that Tesla deployed during the entire last quarter. It would consist of as many as 1,500 Powerpack 2 battery systems."
Xcel Energy is currently soliciting for energy storage and renewable energy projects in Colorado. Along with Tesla, power providers NextERA Energy Resources, Convergent and AEIF Battery Storage have also made bids to build a giant battery, as you can see from this chart posted on pv magazine.
One bid from NextEra is a stunning 150-megawatt system that could run for 10 hours and that, as pv magazine noted, "would be the largest planned anywhere in the world at this moment." In fact, four of the proposed battery projects would qualify for the distinction of "world's largest."
Electrek pointed out that while most of Colorado's electricity currently comes from coal and natural gas, the state is ramping up renewable energy and energy storage projects to boost the efficiency and stability of its power grid.
The move comes after regional authorities declared a state of emergency over the weekend after sightings of more than 50 bears in the town of Belushya Guba since December.
This year's letter from Bill and Melinda Gates focused on nine things that surprised them. For the Microsoft-cofounder, one thing he was surprised to learn was the massive amount of new buildings the planet should expect in the coming decades due to urban population growth.
"The number of buildings in the world is going to double by 2060. It's like we're going to build a new New York City every month for the next 40 years," he said.

After a dearth of action on climate change and a record year of extreme events in 2017, the inclusion of climate change policies within the annual legislation Congress considers to outline its defense spending priorities (the National Defense Authorization Act) for fiscal year 2018 was welcome progress. House and Senate leaders pushed to include language that mandated that the Department of Defense (DoD) incorporate climate change in their facility planning (see more on what this section of the bill does here and here) as well as issue a report on the impacts of climate change on military installations. Unfortunately, what DoD produced fell far short of what was mandated.
Trump is losing his rallying cry to save coal. The Tennessee Valley Authority (TVA) voted on Thursday to retire two coal-fired power plants in the next few years despite a plea from the president to keep one of the plants open.
Earlier this week, the president posted an oddly specific tweet that urged the government-owned utility to save the 49-year-old Paradise 3 plant in Kentucky. It so happens that the facility burns coal supplied by Murray Energy Corporation, whose CEO is Robert Murray, is a major Trump donor.
