> distributed generation, reduces transmission infra costs
Distributed generation does reduce transmission costs slightly, but nowhere near in line with the amount of credit being given. Transmission costs mostly scale with the maximum power demand and the reliability needed, not with actual power delivered. Billing for distribution and grid reliability with a usage-based charge made sense when the power company was an absolute monopoly, but it doesn't with distributed power. Grid connectivity and distribution should be billed as a flat rate, or based on the size of the mains connection. That would be more in line with the actual costs.
