Capital projects, investments into itself that make the company tick. New plants, improve infrastructure (down to the application server). See: https://blog.aee.net/how-do-electric-utilities-make-money
Now, that doesn't excuse them because its entirely possible they did not invest wisely. But simply blaming "profit" is hand wavy anti-corporate speak, which doesn't necessarily explain what is happening.
No, there isn't.

That doesn't make money, it reduces operating expenses and increases operating margins at the same rates. The money still comes from ratepayers. And public entities reduce operating expenses the same way, the benefits (after paying for any debt financing) just go to taxpayers, rather than private investors.
Capital project costs (along with other fixed costs) generally get passed through to rate payers + an approved ROR by the public utility board. Operating expenses cut into this. Capital project costs do not necessarily reduce operation expenses directly.
Private capital is only required to have someone to return dividends to.

Yes, exactly, because it's a for profit institution, it is structurally incentivized to return profits to investors.
> It's a state-sponsored monopoly.
Which makes it being a private, profit-making enterprise nonsensical, exactly.
