RAP developed a model rule for use by U.S. state and local air quality regulators to reduce nitrogen oxide (NOx) emissions from water heaters. This technical support document was published to assist regulators and staff in understanding and making use of the model rule. It describes why water heaters are a significant source of air pollution, why NOx emissions st...
Electric utility regulators are paying closer attention than ever before to individual distribution system investment decisions, in part because of the rapid growth in distributed energy resources and the need for new grid modernization investments. To achieve the best outcomes for ratepayers and society, regulators need robust and comprehensive tools for eval...

This fact sheet, prepared as a poster for presentation at the ACEEE 2022 Summer Study on Energy Efficiency in Buildings, describes the concept of a model rule to reduce emissions of nitrogen oxides (NOx) from fossil fuel-fired water heaters, an opportunity to transform the market for these appliances by driving the adoption of cleaner, more energy-efficient elect...
In a presentation for national advocates, Nancy Seidman and John Shenot proposed an innovative model rule concept to reduce nitrogen oxides emissions from water heaters, a significant source of emissions that has received little attention from state regulators....
In a webinar for the New Mexico Public Regulation Commission, John Shenot explored cost-effectiveness methods and the increasing applicability of benefit-cost analysis for grid modernization investments and distributed energy resources. ...
In a presentation for committee members of the Ozone Transport Commission, Nancy Seidman and John Shenot discussed progress on their innovative model rule concept to reduce nitrogen oxides emissions from water heaters, a significant source of emissions that has received little attention from state regulators....
A growing number of states have considered reforms to their net metering practices in recent years, a period of decreasing prices for distributed energy resources, rapid changes in technology and evolution of the electricity system. Depending on its design, a net metering program can advance specific policy goals while maintaining sound principles of rate de...
In a Maryland Public Service Commission session, John Shenot explored the use of benefit-cost analysis as a promising tool for evaluating distributed energy resources....
In a roundtable webinar discussion, RAP staff highlighted what states can do (and are doing) on a variety of topics — from performance regulation to system planning to rate design — to navigate the energy transition with the customer’s interests always a top priority. The panel also discussed opportunities stemming from federal action....
