2c per kWh, care to quote the source?
I looked up my statement last month from Eversource, it is $0.22029 per kWh for net metering.
The utilities' argument is that if the power wall can export energy back to the grid, then there is no stopping of customer who stores energy in the off-peak hour, then sell it back to grid at peak hours. TOU is coming to Mass.
The utilities will fight every inch of ground to make the process of solar panel and energy storage difficult for their customer. Let the due process plays out. But if the Tesla Power Wall does not have a bulletproof design or set up to avoid exporting energy back to the grid, I'm fearful that the DPU will side with the utilities.
