IREC papers and reports offer independent, thought-leading expertise and insight, including publications in which IREC has collaborated with others. They are divided here into four categories: regulatory; market trends and analysis; workforce education; and permitting/inspection. Click the link for details and to download each publication.
A background on DG and why the size, location and technology of DG resources matter in determining the benefits DG is able to provide. The report also provides an analysis of the cost effectiveness of DG resources and, perhaps most importantly, recommends ways to maximize the benefits that DG can provide to the grid.
This report offers lessons learned from 16 regional and utility-specific Distributed Solar Generation (DSG) studies summarized in a recent review by the Rocky Mountain Institute (RMI), and then proposes a standardized valuation methodology for public utility commissions to consider implementing in future studies.
An overview of policies that will allow California to continue to support distributed generation (DG) while driving projects into the highest-value locations in a manner that enables the state to get the most out of its investment.
Three case studies offer a glimpse at three different utilities’ approaches to offering community solar to their customers.
An introduction to the issues surrounding policy and technical considerations of grid-integrated, renewable energy development.
Since the market for distributed energy storage is still in its infancy, there is a significant need for regulatory guidance and proactive policies to ensure a smooth integration into the existing electrical system. In this report, IREC offers independent insight on how to address these new challenges – and opportunities – in the regulatory arena.
This landmark IREC report offers a unique look at the national movement toward a more modern electricity grid, and offers five insightful approaches for state utility regulators to consider as they facilitate the transition through rules and regulations that govern the electricity system and electric utilities.
A concept paper from IREC and Sandia National Laboratories proposing an Integrated Distribution Planning (IDP) approach to proactive planning for DG growth.
Many states have either adopted net metering policies that capture some of the best practices identified in these IREC model rules or adopted rules that advance the policies contained in IREC’s model. First published in 2003 and updated in 2009.
First developed in 2005 and updated in 2009, the 2013 edition of IREC’s Model Interconnection Procedures synthesizes a number of best practices in the evolution of safe and reliable connecting of renewable energy systems to the utility grid.
Revised in collaboration with The Vote Solar Initiative, these model rules were updated in 2013 to assist stakeholders in developing shared renewables programs that broaden renewable energy access to more consumers.
This report provides clarification on how net metering works in complex competitive markets.
In this paper, the advantages and disadvantages of such an approach to Distributed Generation (DG) are discussed. It concludes with several considerations to address before PURPA could become a viable option for promoting DG growth in many states. Several recent Federal Energy Regulatory Commission (FERC) decisions have provided the needed justification to value the benefits of DG facilities.
