To prevent a big damages to the power companies, here in Spain the people that produce their own electricity with solar panels must pay “el impuesto al sol” (the sun tax). This tax let power companies to continue receiving money from the customers by the infrastructure. The customer can’t let the grid, can’t stop to pay. They can sell energy to the power company, but must pay for the infrastructure. And that is a big disadvantage for the customers that want to get solar panels and save money in Spain.My BMW has to have premium, so it was $3.67/gal at Chevron today, or over $50 to fill-up for the week compared with less than $10 for electricity for the same range. And it's those buying the new turbocharged engines for the higher mpg and power that need to buy premium. Like PHEVs.
The incentive for the power company to spend on battery pack based upgrades, is that they cost millions and millions less than building another coal or nuclear plant, and takes months instead of years to build and go live. This is why the recent new peaker plants that went live are all battery based(storing the energy when demand is low and delivering it when demand is nigher).
In states like yours that have no off peak rates, consumers are going with solar and powerwalls to get themselves off the grid. Because all day when no one is home, the house is storing power in the battery pack to be used in the evening when homeowners return. Reducing or eliminating the need to pull from the grid. It is the solar/battery storage trend with consumers and businesses and school systems, along with charging networks like Superchargers that are going solar/powerpacks, that has power companies worried about their future and resisting off peak rates along with allowing homeowners/businesses to sell back extra power from their solar systems.
The oil and power/coal companies know this, and why both are investing in wind/solar farms and public charging.
