TWEETS

Full retail credit with no subtractions. Customers protected from fees and additional charges. Rules actively encourage use of DG.

A

Generally good net metering policies with full retail credit, but there could be certain fees or costs that detract from full retail equivalent value. There may be some obstacles to net metering.

B

Adequate net metering rules, but there could be some significant fees or other obstacles that undercut the value or make the process of net metering more difficult.

C

Poor net metering policies with substantial charges or other hindrances. Many customers will forgo an opportunity to install DG because net metering rules subtract substantial economic value.

D

Net metering policies that deter customer-sited DG.

Model Rules

Applying the lessons from existing statewide net metering programs and interconnection procedures, IREC has drafted model interconnection procedures and net metering rules for use by state utility commissions and other stakeholders. As states consider adopting or revising programs, these models provide an easy way to emulate effective policies and avoid wasteful mistakes.

 

Model Net Metering Rules

These model rules from IREC provide additional detail regarding net metering policy design and best practices.

 

Model Interconnection Standards

These model interconnection procedures from IREC incorporate the best practices of small-generator interconnection procedures developed by various state governments, the Federal Energy Regulatory Commission (FERC) standards, the National Association of Regulatory Utility Commissioners (NARUC), and the Mid-Atlantic Distributed Resources Initiative (MADRI).

 

Connecting to the Grid Guide

IREC’s Connecting to the Grid Guide provides a comprehensive introduction to both net metering and interconnection policies and technical issues.  The 6th edition of this guide includes explanations of IREC’s updated model interconnection procedures, alternative billing arrangements for net metering, energy storage issues and several other emerging issues in the field.

 

Calculating the Benefits and Costs of Distributed Solar Generation

There is an acute need for a standardized approach to determining the benefits and costs associated with distributed solar generation (DSG). This report offers lessons learned from 16 regional and utility-specific 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
