Net Metering & DISCOMs
DISCOM-specific net metering guides for India and tariff/interconnection guidance for major US utilities.
Net metering policy is where solar economics actually get decided. Two identical 1 MWp systems can have radically different payback periods because of NEM 3.0 in California, gross metering caps in Karnataka, or banking restrictions in Maharashtra. This hub maps live net metering rules DISCOM by DISCOM and state by state, application paperwork, tariff math, timelines, and the rejection reasons we see most often. Cross-reference with the permit hub for the engineering submission package and the finance hub for the resulting cashflow model.
