Re: $2/kwh is a lot of money
It's only going to be paid during "load management events", which I think is PG&E for "getting close to a partial blackout or brownout". During these times, $2/kWh is probably at or below the marginal cost of getting more generation online.
Over here in the UK, National Grid recently paid over $11/kWh for a couple of MW of additional power from Belgium to stop demand disconnection in the south east.
