This letter to the CPUC for the Net Energy Metering 3.0 proceeding of December, 2022, includes a comprehensive literature review of Time of Use rate research that illustrates no TOU study, hypothetical or real-world, to date has shown Low Income households to benefit from TOU rates.
The primary objective for the project team is to analyze cooking session data taken from the Atascadero housing complex and determine if an 1800W induction cooktop is sufficient for their cooking needs. The project deliverables summarized below reflect the data analysis requests of the client (Redwood Energy) and are within scope of what is extractable from the data set provided.
Redwood Energy was contracted by Trinity Church in Menlo Park to deliver a feasibility report and plan for reducing natural gas use on its campus and adding a resilient microgrid so that the campus could be used as a shelter during grid outages. This document includes budget estimates for needed equipment and specific equipment recommendations to replace each gas appliance.
For new homes, an all-electric home is much more economical than adopting a dual-fuel home with two space conditioning appliances. In addition, taking into account the avoided cost of an NG infrastructure cost, the economics of an all-electric home gets even better. For existing homes, the current capital costs of HPSC are only around 10-15% higher than air-conditioners (AC). So already replacing retiring NG furnace or AC with an HPSC makes economic sense. Mandating new homes to be all-electric and incentivizing homes with AC and NG furnace to switch to HPSC will help bring down the installation cost of HPSC, due to economies of scale. Greater customer adoption will require larger outreach and education to consumers, building contractors, plumbers and technicians and developing regional partnerships that set market adoption targets, standards-setting, or performance goals in heat pumps.
