Because of Jamaica’s high retail electricity prices, significant opportunity exists for DPV as an economic alternative. This paper reviews the effectiveness of Jamaica’s net billing pilot program, and identifies remaining challenges including a complex interconnection process, contractual ambiguity, and stakeholder equity concerns. The report provides several specific recommendations like shortening interconnection timelines, reducing caps on individual systems, and moving beyond a pilot phase. Many of these recommendations are applicable to other countries, particularly those with similarly high electricity rates.

Utilities worldwide are concerned about the financial impact of increasing DPV adoption among their retail customers. This report analyzes the impact of DPV deployment on distribution utility revenues and retail electricity tariffs in Thailand. It provides policymakers, utilities, and other energy practitioners a real-world example of how DPV affects certain stakeholders.

Estimating the benefits and costs of DPV helps power system stakeholders evaluate appropriate regulatory measures and compensation programs for DPV. To inform these decisions, this report describes current and potential future methods, data, and tools to estimate the benefits and costs of DPV from the utility or electricity-generation system perspective. Although the report is explicitly written in the context of informing estimation of DPV costs and benefits to the United States electricity system, it provides insights relevant to power systems around the world.

The U.S. state of Minnesota has enacted legislation allowing investor-owned utilities to use a value of solar tariff as an alternative to net metering for DPV. This document details the methodology participating utilities will use to calculate the value of solar tariff to account for several values of DPV (including energy and its delivery, generation and transmission capacity, transmission and distribution losses, and environmental value). The methodology includes detailed example calculations for each step.

When not properly addressed, high penetrations of DPV on a distribution system present issues like voltage overload, reverse power flow, and protection failure, which threaten system reliability. Drawing upon results from a five-year study of the Southern California Edison (SCE) distribution system, this handbook presents a detailed analysis of the potential impacts and mitigation techniques when integrating DPV. Written for distribution engineers, the handbook also provides a study guide for modeling and assessing PV impacts, covering topics such as model development, data validation and measurement, study criteria, and the steps involved in power flow and fault analysis. While the impacts and mitigation techniques described in this handbook are written for utility-scale PV systems (1-5 MW), much of the information is also relevant for the proliferation of smaller, DPV systems.

Capacity expansion modeling is a fundamental tool for planning the future power system. Capacity expansion models can provide insights on possible pathways for the power system under different assumptions about technology innovation, transmission expansion, demand changes, and policies. This report summarizes the experience of capacity expansion modeling at the National Renewable Energy Laboratory (NREL). The authors address in detail NREL’s approach to key questions that arise when modeling future capacity expansion, with a particular emphasis on modeling significant levels of variable RE deployment.

This step-by-step guide provides a comprehensive overview of power system planning and describes the key planning implications related to variable RE deployment and integration, with a particular focus on implications for emerging economics. The second part of the report describes the considerations needed to accurately represent variable RE in energy models and suggests several cross-cutting solutions to improve capacity expansion modeling.

This report reviews grid interconnection codes that relate to the performance of wind turbines, as well as requirements that can validate wind farm and turbine performance. Also reviewed are modeling requirements for simulating the performance of wind farms in the power system. Specifically, the authors examine grid codes from the UK, Germany, Denmark, Spain, Texas, Canada, and Europe.
