Elon Musk asks utilities to buy Tesla’s new Megapack to replace peaker plants

Elon Musk turned to his 28 million followers to help push Tesla’s latest product, the Megapack, to electric utilities in an aim to replace peaker plants.
 
After a year of anticipation, Tesla launched ‘Megapack’ last month.

It’s the company’s latest energy storage product, after the Powerpack and the Powerwall, and it is meant as an even bigger option targeting electric utility projects.

According to Tesla, a single Megapack has up to 3 MWh of storage capacity and a 1.5 MW inverter.

The company’s energy storage business has found some success with electric utility companies through the years with its Powerpack, but the competition has been offering bigger options.

Tesla was competing by simply configuring projects with a lot of Powerpacks, but now the Megapack is a new option better suited for larger projects:

“Using Megapack, Tesla can deploy an emissions-free 250 MW, 1 GWh power plant in less than three months on a three-acre footprint – four times faster than a traditional fossil fuel power plant of that size. Megapack can also be DC-connected directly to solar, creating seamless renewable energy plants.”....

Does he mention how long the battery packs will last? Or the probabilities of it catching on fire? I do not think the reliability is there, especially given Tesla's quality control problems.

The key to long-life is to not max out the batteries, both discharge and charge.  An example would be to charge to 80% and discharge to 30%, needing double the capability of the battery for short term use.  That reduces the fire risk given less stress and increase the life.

The link above talks a bit about the different types of battery design Tesla is expected to use.

One bursts into flames at time of need.  Then what?
