These installations will be required to incorporate “smart” inverter technology, which will be accessible to the utility to facilitate grid reliability. Note that these customers are eligible only for a so-called dual metering arrangement with credits per kWh at the utility’s ‘avoided cost’ (wholesale rate), if they elect to be designated as a Qualifying Facility.
