Title 24 2013 Time Dependent Valuation
For California's Title 24 building standards, E3 is leading the development of the
Time Dependent Valuation (TDV) factors for the California Energy Commission's
2013 building standards. The TDV factors are used to evaluate the cost-effectiveness
of energy efficiency measures in buildings.
2013 Net Energy Metering (NEM) Evaluation
E3 conducted a study to evaluate the ratepayer impacts of the California net energy metering (NEM) program. This study fulfills the requirements of Assembly Bill (AB) 2514 (Bradford, 2012)  and Commission Decision (D.) 12-05-036 to determine "who benefits, and who bears the economic burden, if any, of the net energy metering program," by October 1, 2013.
E3 developed three public models to inform the analysis: (1) the E3 NEM Bill Calculator calculates bill savings of NEM customers, (2) the E3 NEM Avoided Cost Model calculates the ratepayer costs that are avoided due to NEM generation, and (3) the E3 NEM Summary Tool combines and displays all of the costs and benefits of NEM.
More information about using the E3 NEM Summary Tool can be found in Appendix F of the draft report. Appendix B contains details on the bill calculations, and Appendix C outlines the avoided cost methodology.
