The Impact of Rate Design and Net Metering on the Bill Savings from Distributed PV for Residential Customers in California

We analyze the bill savings from PV for residential customers of California’s two largest electric utilities, Pacific Gas and Electric (PG&E) and Southern California Edison (SCE). The analysis is based on hourly load data from a sample of 215 residential customers located in the service territories of the two utilities, matched with simulated hourly PV production for the same time period based on data from the nearest of 73 weather stations in the state.

Connecting to the Grid: A Guide to Distributed Generation Interconnection Issues, 6th Edition

This guide provides a comprehensive introduction to a span of topics that relate to grid-tied renewable energy sources. The sixth edition has been revised to include information on IREC's recently updated model procedures, alternative billing arrangements for net metering, energy storage and several other emerging issues in the field. This guide is designed for state regulators and other policymakers, utilities, industry representatives and consumers interested in the development of state-level interconnection and net metering policies.

Assessment of Rooftop Area in Austin Energys Service Territory Suitable for PV Development

As part of the Solar America Cities program, Austin Energy proposed to perform an assessment of the rooftop area available for PV development within its service area. Austin Energy contracted with Clean Energy Associates (CEA) to perform the analysis. This report summarizes the project objectives, data sources and methodological approach employed, and results.

Key questions addressed by this project were:

Florida's Emergency Shelters Go Solar

Florida has its fair share of dangerous weather conditions including hurricanes, tornados and floods. Florida legislature passed various laws and made revisions addressing disaster planning which required that the Department of Education, in consultation with school boards and county and state emergency management offices, develop design standards for public shelters to be incorporated into State Requirements for Educational Facilities.

NREL Response to the Report Study of the Effects on Employment of Public Aid to Renewable Energy Sources from King Juan Carlos University (Spain)

Job generation has been a part of the national dialogue surrounding energy policy and renewable energy (RE) for many years. RE advocates tout the ability of renewable energy to support new job opportunities in rural locations and the manufacturing sector. Others argue that spending on renewable energy is an inefficient allocation of resources and can result in job losses in the broader economy.

Problems and Solutions: Training Disaster Organizations of the Use of PV

Experience has shown that photovoltaic systems can be used effectively to support electrical power during emergencies. This paper describes what is being done to deploy PV following disasters, types of training needed, target audiences, available training material and types of workshops being conducted.

Geographic Variation in Potential of Rooftop Residential Photovoltaic Electric Power Production in the United States

This paper describes a geographic evaluation of Zero Energy Home (ZEH) potential, specifically an assessment of residential roof-top solar electric photovoltaic (PV) performance around the United States and how energy produced would match up with very-efficient and super-efficient home designs. We performed annual simulations for 236 TMY2 data locations throughout the United States on two highly-efficient one-story 3-bedroom homes with a generic grid-tied solar electric 2kW PV system.

Disasters: Photovoltaics for Special Needs

This paper emphasizes on the needs to protect special needs people because of their health conditions and evaluates the approaches to prevent injury. Disaster resistant homes with a renewable energy source would reduce shelter efforts, emotional stress and recovery costs.
