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.

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 amount of time required to complete the distributed PV interconnection process can be a significant driver of interconnection costs to PV project developers, utilities, and local permitting authorities. Using data from over 30,000 residential and small commercial systems, this report provides insights from the United States (both nationally and in five states with active solar markets) on the length of time needed to interconnect and deploy distributed PV. The report assesses the number of business days required to 1) apply for and receive utility interconnection review and approval; 2) construct the PV system; 3) pass final local jurisdictional building permit inspection and submit permission-to-operate paperwork to the utility; and 4) receive permission to operate from the utility. It also provides insights on some of the drivers of the interconnection process timeline, which can be used to inform the development of interconnection procedures.

Standard IEEE 1547 is an example of an interconnection standard (commonly used in North American power systems) providing technical rules for interconnecting distributed generation resources with the electric grid. The standard’s guide introduces the background and rationale for the technical requirements, facilitates use of the standard by characterizing distributed resource technologies and related interconnection issues, and provides approaches and information to support interconnection and implementation. The standard was updated in 2014 with an amendment providing existing information on voltage, voltage regulation, and frequency.
