This report discusses the links between weather forecasts and photovoltaic (PV) output, as well as the various methods for conducting forecasting. Also included is an example of “upscaling” in which representative systems are used to develop a forecast for a larger pool of systems. The authors also analyze the accuracy of tools and present a survey of tools used worldwide.

Based on a series of interviews with thirteen operating entities in the Western Interconnection of the United States, this report summarizes practices, lessons learned, and priorities related to the implementation of wind and solar forecasting. The operating entities provided insights regarding cost assignment, forecasting accuracy and uses, data collection, curtailment and outages, probabilistic forecasting, distributed solar production, control room integration, and staff training, among other topics.

This report describes the state-of-the-art with respect to variable generation integration, mostly focused on the United States but also providing a few international examples where particularly relevant. The report is predominantly based on an extensive literature review with input from General Electric (GE) and PJM. Pages 97–119 focus on forecasting.

The North American Electric Reliability Council (NERC) examines best practices for variable RE generation forecasting. The authors suggest using forecasts across timeframes and as close to real-time as is possible. The report focuses on forecasts from real-time to the coming 48-hours and how the forecasts can be best communicated to and utilized by system operators.

This report summarizes the key changes to power system planning and operations that FERC Order 764 encourages. The authors outline the reasons why traditional electricity scheduling practices may lead to system inefficiencies in the presence of variable RE generation. While compliance costs for renewable energy producers are expected to be minimal, the report estimates that complete compliance by regional transmission operators and independent system operators will take many years to achieve due to challenges associated with cost allocation.

In 2010, the United States’ Midcontinent Independent System Operator (MISO) began a process to work with stakeholders to design a new market mechanism that utilizes the benefits of wind energy and reduces the relevance of the non-dispatchability of the technology. This guide outlines MISO's approach to wind forecasting and practices to improve ramping capabilities.

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.

This report examines various compensation methodologies for demand response programs in Mexico. 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. This report presents three case studies, including New England, California, and Hawaii.
