    I believe each Powerpack stores 100kW.

    For 480 kW power you need at least 1000 kWh according to Tesla's website. Not including transportation and installing that's $607k each. So five of them would cost at least $3M. The news itself says

    But note that it also says

    That's over 44 years for the ROI

    It will save the school $10,000 per month (likely from demand shaving or self consumption and TOU metering), but they didn't pay for the system, so it makes no sense to use that figure for ROI calculation.

    Yeh, but what if some organization did pay for it?

    Then that organization would collect all the benefits that the college is getting plus some of the incentives that paid for the college's installation and get a ROI much shorter than what you said.

    ... and then, some will likely want to cut 10k a month out of their budget.

    Yeh but then there's still incentives. We can't rely on incentives forever.

    Most of the incentives are for the battery purchaser to help improve grid stability by absorbing or releasing energy on command from the grid operator. That will always be a benefit to the grid, so why should there be an end to the incentive scheme? I think the unique thing about this college installation is that they captured the ongoing demand response payments and capitalized it into the installation costs.

    The incentive schemes at work here are very different than the Federal Tax Credits for EVs and Renewable Energy.

    Actually $607,000 buys 10 Powerpacks, 500 kW worth of inverters, and cabling [installation not included]. Five power packs with inverter and cables would be roughly half of that or $304,000

    Why not?
    The fossil fuel companies still are:(

    But I agree, we shouldn't rely on them. They are there to help new technologies.
    As they get cheaper, they won't be needed.

    Each of the five they bought has 480kW power which would need that 500kW incerter. So, 5*$607k
