AI summary The document requests information on the total annual avoided costs for solar generation exported by Net Metering customers and compares these costs to the incremental cost of providing energy offset by bill credits. The response outlines the methodology used, including load profiles for different rate classes and the use of AMI data.

hourly consumption and exported generation data.[1](#page-5-0) 1 Total estimated solar generation was matched to Appendix A of the Report, with behind-the-meter generation calculated as the difference between total generation and measured...

AI summary The document outlines a methodology for estimating the costs and benefits of net metering by analyzing hourly consumption and exported generation data. It uses irradiance-based weighting, marginal fuel prices, and tariff structures to calculate avoided fuel costs and incremental costs. The analysis considers energy credits and provides an indicative estimate for the 2026 NM Report.

1 Customers who added generation or who began service partway through 2025 are not included in the calculation of a representative customer. 1 (a) The values referenced in Appendix A of the Report represent the total production of all net...

AI summary The text discusses the exclusion of certain customers from the calculation of a representative customer and references metrics related to net metering (NM) credits and system savings, noting a discrepancy of $9.2 million.
