   Discoms buy power at different rates for periods of the day. If producers/ consumers (“prosumer”) sell a lot of power during the day (ie. solar) and buy expensive peak power in evening period at the SAME rate, then discoms will get short-changed; and smart producers will make a lot of money by going for large scale solar production. Thus, discoms are against ANY corporate or large solar producers taking advantage of them via net metering. 

   The reason the discoms pay different hourly prices is due to supply and demand. The electricity grid must supply power at all times, even when solar is not there. For peak demand, which is in the evenings, discoms collectively pay a high price for booking capacity which will be idle for the rest of the day. Gross metering pays producers the daylight rates but charges consumers peak-time rate. Net metering is a simple system that gives the small producer a higher rate as a way of encouraging them to go solar. Flexible hourly system is the fairest. It would be useful for matching large consumers and large producers, and for encouraging more solar and more consumption in non-peak hours.

Is gross metering a bad rule for large solar roof-top producer-consumers?
