|Distributed Generation Toolkit|
Interest among customers in customer-owned renewable generation is growing, and utilities must have policies to address interconnection of these generators. Solar PV generation, in particular, becoming more economical due to falling prices combined with state and federal tax incentives. The resources on this page are designed to help utilities understand the issues associated with distributed generation, and adopt appropriate policies.
Interconnection Standards and Metering
IAMU Model Interconnection Standards These model standards have been written so that a utility can adopt them into their service rules. The Interconnection Standards include:
These model standards cover small systems (up to 25 kW), but the utility's obligation to interconnect extends to larger systems. Municipal utilities may consider the interconnection rules contained in Iowa Administrative Code 199 Chapter 14 for more comprehensive standards.
Additional Utility Resources
Utilities' Obligation to Interconnect with Qualifying Facilities This document outlines municipal utilities to interconnect with customer-owned generation under federal and state law
Guide to IEEE Standard 1547 for Interconnection Utilities in Iowa are required to follow IEEE Standard 1547 when interconnecting customer-owned generation. This document provides and overview of the standard.
Iowa Solar Potential The Iowa Environmental Council, with funding from the Iowa Energy Center, developed a document on the potential for solar PV in Iowa. The document can be found at the link above.
Community Solar Programs in Iowa
Community Solar in Iowa Report The DOE's National Renewable Energy Lab's (NREL) Solar Technical Assistance Team wrote a report on community solar programs in Iowa. The report can be found at the link above.
Community Solar Scenario Tool The DOE's national Renewable Energy Lab (NREL) developed a spreadsheet based tools to help utilities do an initial analysis of a community solar project. The tool was designed specifically with small utilities in mind.
Consumer Guides to Distributed Generation
Consumer's Guide to Distributed Generation A consumer's guide to distributed generation was developed as part of the Iowa Utilities Board's notice of inquiry on distributed generation (NOI-2014-0001). The guide is technology neutral, and utilities are encouraged to provide the guide to customers interested in installing distributed generation.
Solar Power for Your Home The Edison Electric Institute (EEI) commissioned this report to provide consumers a comprehensive guide on distributed solar generation. It is a good resource for utilities and customers.
