Why would net metering go away? With distributed production and net metering a power company becomes an electricity broker instead of sole producer.
Power companies already buy much of their electricity from independent power generators. However, for the economics to work, producer prices need to be lower than retail prices. These prices change throughout the day, based on demand.
Net metering results in people getting paid the retail price instead of the producer price.
A decentralized power system is going to have a lot of battery backup and that might even be more important than the solar panels?
