An Overview of Behind-the-Meter Solar-Plus-Storage Regulatory Design: Approaches and Case Studies to Inform International Applications

Behind-the-meter energy storage systems paired with distributed photovoltaic (DPV) - with the capability to act as both generation and load - represent a unique and disruptive power sector technology capable of providing a range of important services to customers, utilities, and the broader power system. How should regulators, utilities, and policymakers manage the range of challenges and opportunities that increased behind-the-meter energy storage deployment will bring to the power system, in particular when these systems are paired with DPV? This report is intended to offer key regulatory considerations for facilitating DPV-plus-storage programs for retail customers; relevant cases from U.S. states are provided as examples of how novel regulatory issues related to behind-the-meter energy storage systems paired with DPV are being addressed in practice. At a high level, designing a regulatory framework that aligns DPV-plus-storage deployment with larger policy objectives requires thoughtful deliberation across a range of technical and economic issues. While this report attempts to segment many of these issues into distinct topics to enhance reader understanding, in reality, DPV-plus-storage regulatory issues are all closely integrated, and design decisions on a single aspect often have broader implications. With that in mind, this report outlines a series of steps that can be employed by regulators to approach DPV-plus-storage regulatory design.

Distributed Solar Photovoltaic Cost-Benefit Framework Study: Considerations and Resources for Oklahoma

This baseline study on approaches to distributed solar photovoltaic (DPV) compensation and valuation mechanisms is the first part of a two-part deliverable. The goal of this report is to first clarify the range of compensation structures used for DPV across the country and what factors are considered in each framework, including net metering and billing, value of solar, and other models.

International Applications for Floating Solar Photovoltaics

To ensure reliable, affordable, and sustainable future power supplies many developing countries are exploring options for new generation. Floating solar photovoltaics (FPV) are becoming an increasingly competitive option. However, the technology is still nascent, and many potential adopters have questions about its benefits, how to analyze it appropriately, and the underlying technology. The U.S. National Renewable Energy Laboratory (NREL) is a global leader in FPV and is looking to develop international implementation, analysis, and research collaborations to further advance the technology and support global deployment. This concept note provides an overview of FPV and the potential areas of collaboration that NREL would be interested in supporting.

Informing Mexico's Distributed Generation Policy with System Advisor Model (SAM) Analysis

The Government of Mexico recognizes the potential for clean distributed generation (DG) to meaningfully contribute to Mexico's clean energy and emissions reduction goals. However, important questions remain about how to fairly value DG and foster inclusive and equitable market growth that is beneficial to investors, electricity ratepayers, electricity distributors, and society. The U.S. National Renewable Energy Laboratory (NREL) has partnered with power sector institutions and stakeholders in Mexico to provide timely analytical support and expertise to help inform policymaking processes on clean DG. This document describes two technical assistance interventions that used the System Advisor Model (SAM) to inform Mexico's DG policymaking processes with a focus on rooftop solar regulation and policy.

Demand Response Compensation Methodologies: Case Studies for Mexico

This report examines various compensation methodologies for demand response programs in Mexico. This report presents three case studies, including New England, California, and Hawaii. Demand response (DR) can refer to a variety of approaches to changing the amount and timing of customers' electricity use, allowing the electricity supplier to more easily balance electricity supply and demand. The level of compensation for a DR program will depend greatly upon both the regulatory context of the electricity supplier, as well as the economic circumstances of the DR providers. For a regulated utility, a proposed compensation level may need to pass regulatory approval. To determine the value of DR resources, a regulatory body typically seeks to determine the costs that the utility would avoid if demand-side resources 'produce' energy.

The Status and Outlook of Distributed Generation Public Policy in Mexico

Mexico is a regional leader in setting goals for reducing greenhouse gas emissions (GHG) and distributed generation (DG) development is a key priority for the country's policymakers. Current DG policies have fostered growth but need to be modernized to serve current needs and accommodate higher penetration levels. In this report, NREL summarizes international DG policy experiences and best practices and identifies the potential opportunities for policy reform.

Informando la Política de Generación Distribuida de México con Análisis del Modelo para Asesoría de Sistemas (SAM)

El Gobierno de Mexico reconoce el potencial de la generacion distribuida limpia (GD) para contribuir significativamente a los objetivos de energia limpia y reduccion de emisiones de Mexico. Sin embargo, aun quedan preguntas importantes sobre como valorar justamente a GD y fomentar un crecimiento de mercado inclusivo y equitativo que sea beneficioso para los inversionistas, los contribuyentes de electricidad, los distribuidores de electricidad y la sociedad. El Laboratorio Nacional de Energia Renovable (NREL) de los EE. UU. se ha asociado con instituciones del sector energetico y partes interesadas en Mexico para proporcionar apoyo analitico oportuno y experiencia para ayudar a informar los procesos de formulacion de politicas sobre GD limpio. Este documento describe dos intervenciones de asistencia tecnica que utilizaron el Modelo de Asesor del Sistema (SAM) para informar los procesos de formulacion de politicas de GD de Mexico con un enfoque en la regulacion y politica solar en tejados.

Low-Income Community Solar: Utility Return Considerations for Electric Cooperatives

The objective of this short report is to identify project structures that make low-income community solar projects more cost-effective, replicable, and scalable, for electric cooperative and municipal utilities. This report explores the tradeoffs between providing energy bill savings for low-income subscribers and utility project returns, as well as some of the key lessons learned from existing successful low-income community solar pilot projects.
